  • Minerals

    The living body is a complex of many chemical components.  Much of our flesh, from skin to muscles and internal organs to the brain and nerves is made up of organic matter formed from carbon, hydrogen, oxygen, and nitrogen.  These basic elements are recycled back into the earth when we die and the body decays. “Remember, man, that dust you are and unto dust you will return” is not just a biblical statement.  It is the reality of life.  It is as much fundamental biology as it is fundamental spirituality.  The very dust that clings to your feet or you breathe through your nose might have once been part of the bodies of your ancestors. Even when a body is cremated, the smoke, made of these elements, comes back to the earth.

    Minerals are elements from the earth that we take in through our foods.  They are essential nutrients because they cannot be made by living things but are used by living things for growth, development, and functioning.  They serve structural and functional roles and some (electrolytes) are constituents of body fluids.  Plants take up minerals from the soil.  Animals receive minerals chiefly from the plants they consume and also from eating other animals and from drinking.

    Some of the important functions of minerals in the human body are for building strong bones, for brain and nerve function, for the functioning of the heart, and for making various hormones that regulate and maintain body functions.

    There are two kinds of minerals: macrominerals needed in large amounts and microminerals needed in trace amounts. The macrominerals include calcium, phosphorus, magnesium, sodium, potassium, (the five major minerals in the human body), chloride, and sulfur. Trace minerals include iron, manganese, copper, iodine, zinc, cobalt, fluoride, selenium and molybdenum.

    If you want to ensure you get enough minerals in your diet, there are foods that are certain sources of multiple minerals.

    Nuts may have up to eight minerals including calcium, copper, iron, phosphorus, magnesium, selenium, and zinc.  A handful a day is good, healthy snack.  Beans (and bean foods such as moin moin, bean cakes, and tofu), and lentils are equally rich in variety of minerals including copper, iron, potassium, phosphorus, magnesium, and zinc. All economic classes can benefit from the richness of beans and lentils which are also rich in vegetable protein and fibre.

    Dark leafy green vegetables contain a rich array of minerals too, such as calcium, copper, iron, potassium, magnesium, and zinc.  The minerals are not destroyed by cooking, therefore vegetable soups made from such leaves are rich in minerals.

    Fish such as salmon, tuna, and mackerel contain minerals such as calcium, potassium, phosphorus, magnesium, and selenium. Eating canned sardines and mackerel which contain the fish bones is a good sources of calcium from the bones.  Fish is good for all economic classes and is a rich source of protein and omega 3 fatty acids which are good for cardiovascular health.

    Seeds such as almond seeds, pumpkin seeds, egusi, and sunflower seeds, are rich in minerals such as copper, iron, phosphorus, selenium, and zinc.  Including them in meals regularly is a source of good health.

    Shellfish such as oysters, scallops, mussels, and clams contain minerals such as copper, iron, phosphorus, selenium, and zinc. They also tend to contain omega 3 fatty acids and vitamin B12.

    Whole grains in oatmeal and other breakfast cereals, breads, swallows, and other foods are a sources of a variety of minerals including iron, phosphorus, selenium, and zinc, and should be included in our diet regularly.  They are also a good source of energy and fibre.

    Other foods that we can add to our diet regularly because they have a variety of minerals are meat (for iron, phosphorus, selenium, and zinc); milk and yogurt (for calcium, potassium, phosphorus, and magnesium); cocoa (for iron, magnesium, and zinc); avocado pears (for copper, potassium, and magnesium); cheese (for calcium, copper, and phosphorus); mushrooms (for copper, potassium, selenium, and zinc); and dried fruits such as raisins, dates, figs, prunes and apricots (for copper, potassium, and magnesium).

  • Functions of Vitamin C and the Adek vitamins

    Vitamin C or ascorbic acid is important in the synthesis of collagen, the main structural protein around cells in connective tissues and in the skin.  Collagen keeps our skin firm and resilient and protects it from wrinkling.  Vitamin C function also keeps the blood vessels strong and holds the teeth in their sockets. Vitamin C is essential for healthy bones and teeth, gums, and blood vessels.  It plays a significant role in tissue repair, synthesis of some nerve transmitter molecules (neurotransmitters) and brain function, and supports immune function. Vitamin C helps the body to absorb iron. Vitamin C deficiency leads to scurvy which is characterized by weak blood capillaries, poor wound healing, bone deformity in children, bleeding and inflamed gums, loose teeth and anaemia. Vitamin C is also an antioxidant that neutralizes harmful reactive molecules thereby it helps to prevent cell damage caused by reactive molecules and reduces risk of diseases such as heart disease and some cancers, including those of the mouth, oesophagus, stomach, and breast.

    We have discussed vitamin A which is one of the fat soluble vitamins A, D, E and K.

    Vitamin D is chemically a steroid structure and acts like a hormone.  If we are regularly and sufficiently exposed to sunlight, our skin can synthesize vitamin D under the influence of sunlight.  If we do not get enough sunlight we would need dietary supplement of vitamin D.  Under sunlight the skin produces cholecalciferol which is then converted by the liver to calcidiol and then by the kidneys to calcitriol, which is the active form of vitamin D in the body.  Vitamin D promotes intestinal absorption and metabolism (body usage) of the minerals calcium and phosphorus.  It is important for maintenance of normal blood levels of calcium and phosphorus which are utilized to form teeth and bones and give bones strength.  Deficiency leads to osteomalacia (softening of bones) in adults and rickets in children seen as bone deformities such as bow legs. Supplements can reduce the risk of non-spinal fractures and skeletal deformities.

    Vitamin E is an antioxidant.  Antioxidants neutralize reactive molecules that can damage cells.  Vitamin E protects the heart, eyes, nerves, and helps in skin healing and prevents scarring.   It may prevent degenerative conditions such as Alzheimer’s disease and may protect against prostate cancer. Premature or low weight babies who do not absorb fat well may become deficient in vitamin E. Vitamin E deficiency can cause peripheral neuropathy, muscle problems, ataxia, eye disease such as retinopathy, red blood cell destruction and anaemia, and impairment of immune responses.

    Vitamin K is an essential player in the formation of blood clotting factors.  It activates proteins and calcium essential to blood clotting. Vitamin K is also important for controlling binding of calcium in bones and other tissues.  It reduces risk of hip fractures.  Deficiency of vitamin K results in abnormal bleeding such as nosebleeds and internal haemorrhage.

    In summary, vitamins are very important for good looks, good health, and ability to function well in life.  In order to obtain all the vitamins we have discussed, we need to eat a variety of foods regularly and some fresh fruits and vegetables should be included.

    As with many aspects of life in Africa, we don’t lack natural resources but we are often poor in standard of living.  For lack of knowledge, people hunger and thirst, people are malnourished, people suffer, and people perish.  With the abundant sun and abundant rain, there should be such a variety of foods from fruits and vegetables to carbohydrates and oils that malnutrition should not be a problem in Africa. Vitamin deficiency should not be an issue even amongst the lower income people. We do need to apply more science to industry and to profitably utilize natural products for better life and living in Africa. Africa’s paradox of not lacking but being poor can be solved through scientific knowledge from a culture of research and development.

  • Functions of the B complex Vitamins in the body

    Vitamin B1 or thiamine is a coenzyme in metabolic processes that convert carbohydrates that we obtain from foods into energy that is used by the heart, muscles, and nervous system for normal function. Without energy, these organs are like a vehicle without fuel.  They cannot move on with their functions well. Deficiency of vitamin B1 in the diet leads to beriberi, a disease with dysfunctional heart and nervous system. Initially, deficiency manifests as a group of symptoms that include fatigue, weak muscles, and anorexia.  Then the person begins to lose weight and manifest mental changes such as irritability and confusion. The mucosal surfaces of the mouth, gums and teeth are affected and the lips manifest cracks.  Extreme deficiency causes anaemia, paralysis and muscular wasting. In adults two types of beri beri are wet and dry beriberi.  Wet beriberi affects the heart and circulatory system and can lead to heart failure. Dry beriberi damages the nerves and can lead to decreased muscle strength and muscle paralysis.

    Vitamin B2 or riboflavin is involved in enzymatic functions.  It is important for the conversion of food into energy and for healthy skin, hair, blood and brain. It protects against sores and swelling of the mouth and lips and deficiency of this vitamin manifests as inflammation of the lining of the mouth and skin, itching and irritation of the lips, eyes, skin and mucous membranes.  The eyes may become hypersensitive to light.

    Vitamin B3 or niacin is also essential for metabolic functions involving enzymes that release energy from carbohydrates.  It is important for healthy skin, the nervous system, and the digestive system. Its deficiency manifests as inflammation of the skin and mucous membranes of the mouth, rectum and vagina, halitosis (bad breath), anorexia (fear of eating and weight loss),   indigestion, diarrhoea, low blood sugar, fatigue, muscular weakness, limb pains, skin eruptions, and inflammation.  Brain function may be affected leading to headaches, dizziness, insomnia, mental retardation or depression

    Viitamin B6 or pyridoxine is a cofactor for certain enzymes that regulate the metabolism of amino acids (from meats) and carbohydrates.  It is important for healthy functioning of the nervous system including brain function and for production of red blood cells. It may lower the risk of heart disease.  Deficiency leads to skin disorders, inflammation of the mouth, nausea and vomiting, dizziness, weakness, abnormality of the nervous system, poor coordination, confusion and insomnia.

    Vitamin B9 or folate or synthetic folic acid is an important factor in nucleic acids DNA and RNA (genetic material) synthesis and is necessary for cell division and generation of new cells. Folate is needed when there is rapid growth of cells and tissues such as in infancy, adolescence, and pregnancy. Folic acid and vitamin B12 are together important for the production of red blood cells and for iron to function in the body.  Folate deficiency leads to megaloblastic anemia a condition in which red blood cells are larger than normal and underdeveloped and the person affected has reduced growth rates.

    In pregnancy, folate is important for the foetus’ neural tube to develop into the baby brain and spinal cord.  Sufficient folate taken in early pregnancy helps prevent brain and spine birth defects such as spina bifida and anencephaly. Women who are pregnant or are likely to become pregnant should take sufficient folic acid to prevent these neural tube defects and miscarriage

    Folate is important for normal brain functions and mental and emotional health.  It is also believed to promote sperm viability and male fertility.  Because folate is involved in the conversion of homocysteine into methionine, lack of folate leads to accumulation of homocysteine and the related cardiovascular problems and stroke.

    Folate given with other B vitamin supplements, vitamin B6 and B12, can reduce risk of age related macula degeneration of the eyes.

    Lack of folate can lead to various symptoms including sore tongues, diarrhoea, loss of appetite, weight loss, weakness, headaches, heart palpitations, irritability, forgetfulness, and behavioural disorders such as dementia.

    Vitamin B12 or cyanocobalamin is important in nucleic acid synthesis and for the production of new cells including blood cells and in the breaking down of some fatty acids and amino acids. It protects nerve cells and facilitates their normal growth.  Lack of vitamin B12 intake can cause anaemia and nervous system damage.

    Uniquely, vitamin B12 is not found in natural plant foods. In synthetic cereals, it is added. It is naturally abundant in meats and fish and is also found in smaller amounts in milk and eggs. Vegetarians who eat only plant foods may not get necessary amounts of vitamin B12 and this can result in anaemia and nervous system damage. Vegans need to take enough foods that are fortified with vitamin B12 such as soy products and fortified cereals, or take vitamin B12 supplements. Vitamin B12 deficiency causes the same type of anaemia as folate deficiency but in addition B12 deficiency causes irreversible damage to the central and peripheral nervous systems. Taking folate will reverse B12 deficiency megaloblastic anaemia but will not stop B12 deficiency neurological damage.

    Vitamin B12 is absorbed in the intestines with the help of intrinsic factor.  People who lack intrinsic factor develop pernicious anaemia or megaloblastic anaemia due to lack of intrinsic factor.  Vitamin B12 may lower the risk of heart disease. Symptoms of its deficiency include numbness or tingling of the extremities and an abnormal gait.

  • Functions of Vitamins in the body

    For most people in a struggling economy, pay day is possibly the happiest day of the month. To be able to eat well, at least for a while, is a wonderful thing. One can eat proteins, vegetables, and fruits, not just carbohydrates to fill up.

    The feeding economics of households vary but whatever budget we work with, we do need to ensure we include in our diet a variety of food types and a variety of foods from each type.  For example, beans, groundnuts, walnuts, and melon seeds are all seeds and nuts.  Yams, cassava, and potatoes are vegetable tubers.  Rice, millet, wheat, and corn are all grains. Liver, beef, and kidney are all meats. Oranges, limes, and grapefruits are all citrus fruits.  Bananas, mangoes, and guavas are all fruits.  Mackerel, stock fish, tilapia are all fish.  Chicken, turkey, and eggs are all poultry. When we include a variety of food types in our diet, we ensure that we get all the vitamins as different foods contain different vitamins and to different extents.

    Since we cannot do maths with every meal, forever calculating and measuring , the  easy thing to do is to include a variety over a course of time such as within a month: rice once in a while, cassava once in a while, yam once in a while; liver once in a while, chicken once in a while, kidney once in a while, stock fish once in a while, beef once in a while, mackerel once in a while; oranges once in a while, mangoes once in a while, avocados once in a while, etc., based on what foods we like and can afford and are safe for our peculiar conditions. Some foods such as rice, cassava, and bread are staples and we tend to eat them almost every day, but they should be combined with a variety of other foods to ensure we get all the vitamins.

    Apart from variety of food types, we also need to include something fresh (uncooked vegetable and fruit) amongst the foods we consume daily because cooking can destroy some vitamins or reduce the amount of some vitamins in foods. Fresh foods will always give us some vitamins.  In affluent countries, a vegetable salad is a regular course in a main meal and fruits are also always at the table.

    Why the fuss about vitamins?  We will now consider the functions of various vitamins.

    Vitamin A

    The bright orange colour of carrots is due to carotene compounds or carotenoids which are converted to Vitamin A. They are present in many fruits and vegetables.  In animal foods, they are present as retinol. Vitamin A is important for the functioning of the eye because it is needed to produce retinal.  Retinal is important the transmission of light sensation in the retina of the eye. Vitamin A compounds in foods are important for maintenance of eyesight.  Deficiency of vitamin A leads to night blindness.

    Another role of vitamin A is to promote the growth of skin, hair, bones, and teeth. Deficiency can lead to dry, rough skin; poor bone and teeth growth and development; and a susceptibility to infectious diseases. Vitamin A is also important in reproduction and in maintaining a healthy immune system.

    Vitamin A compounds are antioxidants and in this role they can prevent some cancers and fight heart disease. Beta carotene protects cells against oxidation damage that can lead to cancer.

    Infants fed on excessive carrots can temporarily develop carotenemia with a yellowish skin colour.

    B Complex Vitamins

    The B complex vitamins include thiamine(B1), riboflavin (B2), niacin (B3), pantothenic acid (B5), pyridoxine (B6), biotin (B7), folic acid (B9), and cyanocobalamin (B12).  They are important for many processes within the body.  These include processes that lead to energy production, formation of red blood cells, production of new DNA for multiplication of cells and growth and repairs.

    The B complex vitamins are important for nerve and brain function, for healthy intestines, and for a healthy functioning of the heart and blood vessels.  We shall discuss them one by one.

  • Classes and dietary sources of Vitamins

    Little things that we fail to do now or that we do wrongly in the present can cheat our future in life and beyond.  If we want to be fair to the future we need to take care of many little things in the present.  For good health, this is especially so with vitamins. In order for us to make sure we take enough vitamins we need to know about them.

    A vitamin is a chemical substance that our bodies need in small amounts and cannot synthesize enough of it and must obtain it from the diet, hence it is an essential nutrient.

    The chemical structures or compounds that we know as vitamins are not always universally vitamins. For example, while vitamin C is a vitamin for humans, it is not for many animals that synthesize this compound in their bodies.  Another example is vitamin D which is essential to take as a nutrient for people who are not sufficiently exposed to sunlight.  In people who are exposed to the sun, the ultraviolet light of the sun promotes synthesis of vitamin D in the skin.  Many people take vitamin supplements without needing them.  In some disease states, we may need to take supplements.  In normal health it is best to eat the right foods to get a good combination of vitamins and to get enough of each vitamin.

    Our discussion in vitaminology begins with classes of vitamins.  Some vitamins dissolve in water and we call them the water soluble vitamins.  They are vitamins B1, B2, B3, B6, B7, B9, B12, and vitamin C.  I have not decided to add B17 because it is in the middle of some scientific argument. Some vitamins dissolve in oil and we call them the fat soluble vitamins. They are vitamins A, D, E, and K. The fat soluble vitamins are more readily stored in the body in fatty tissue.

    Vitamins B11, B13, B14, B15, and B16 are folates like vitamin B9.  The vitamins of the B complex have been named up to vitamin B22.  The D vitamins have been named up to vitamin D7.  Why no vitamins F, G, H, I, and J?  The vitamins that were so named have been either discarded as false vitamins or reclassified as a B vitamin which is now a complex of vitamins that are closely related. Vitamin H, now vitamin B7 or biotin is an example of a reclassification. Interestingly, this vitamin, biotin, is present in large amounts in some cancer cells. Scientists through molecular engineering, attach certain anticancer drugs to this vitamin so that the drug gets concentrated in cancer tissue and spares normal tissues of the body.  This is targeted drug therapy.

    Many vitamins were discovered decades ago and much is known about their functions.  We should be familiar with vitamin sources in our diet.  Let us look at them.

    Vitamin A (retinol or beta carotene) was discovered in 1913. It is found as retinol in animal foods and as carotenoids in plant foods, compounds which our bodies convert to vitamin A.   These sources of vitamin A can be found in cod liver oil, dark leafy greens such as greens, spinach, and kale, beef, liver, lean ham, pork chops, eggs, shrimp, fish, fortified milk, cheddar cheese, darkly coloured orange fruits and vegetables such as carrots, sweet potatoes, pumpkin, cantaloupe, apricots, peaches, and mangoes.

    Vitamin B1 (thiamine) was discovered in 1910.  It can be found in rice and other whole and enriched grains, liver, lean pork, seeds, nuts, and legumes, bananas, most fish, liver, nuts and seeds, potatoes, peas, watermelon, avocado, and poultry.

    Vitamin B2 (riboflavin) was discovered in 1920.  It can be found in whole grains and fortified cereals, meat, dairy products such as milk, yogurt, and cheese, eggs, fish and shellfish, poultry, kiwi, avocado, broccoli, turnip greens, and asparagus.

    Vitamin B3 (niacin) was discovered in 1936.  It can be found in meat, fish, poultry, fortified and whole grains, mushrooms, potatoes, mangoes, lentils, and peanuts.

    Vitamin B5, (pantothenic acid) was discovered in 1931.  It can be found in meat, poultry, whole grains, and many foods.

    Vitamin B6 (pyridoxine) was discovered in 1934.  It can be found in fortified cereals, soy products, meat, dairy products, bananas, watermelon, brewer’s yeast, wheat bran, walnuts, brown rice, meat, fish, poultry, potatoes, and soy.

    Vitamin B7, (biotin) was discovered in 1931.

    It can be found in fruits, meats, dairy products, and eggs.

    Vitamin B9 or folic Acid (folate) was discovered in 1941.  It can be found in dark green vegetables, dry beans, peas, and lentils, enriched grain products and fortified cereals, liver, orange juice, wheat germ, and yeast.

    Vitamin B12 (cobalamin) was discovered in 1948. It can be found in liver, eggs, fish, poultry, meat, dairy products and other animal products and in fortified cereals and fortified soymilk.

    Vitamin C (ascorbic acid) was discovered in 1920.  It can be found in citrus fruits such as oranges and grapefruits and citrus fruit juices, in red, yellow, and green peppers, potatoes, broccoli, spinach, strawberries, tomatoes, Brussels sprouts, and most fresh foods in various amounts.

    Vitamin D (calciferol) was discovered in 1920. It can be found in cod liver oil, fortified milk, margarine or cereals, dairy products, fatty fish, liver, and eggs.

    Vitamin E (tocopherol) was discovered in 1922.   It can be found in fortified cereals, wheat germ oil, unrefined vegetable oils, leafy green vegetables, seeds, nuts such as groundnuts, peanut butter, and whole-grain.

    Vitamin K (phylloquinone) was discovered in 1929. It can be found in dark green leafy vegetables such as collard greens, spinach, and kale, cabbage, liver, eggs, milk, broccoli, and sprouts.

    Many of the staple foods we eat should be well analysed and scientifically evaluated to help people make rational choices.

  • Vitamins

    Life and love are perhaps the most powerful forces on earth, more powerful than nuclear weapons and space rockets and money and information and probably all we consider as powerful. As powerful as life is, it depends on many little things.  Some of these little things can themselves be described as small and mighty and vitamins fall into this category. Vitamins can make the difference between life and death.

    What are vitamins?   They are vital substances, originally thought to be chemicals called amines (vital amines), but now known to be of various chemical classes as well as amines. The word vital is from Latin “vita” which means life.  Vitamins are substances that are important for maintaining biologic life.

    In 1911, at the Lister Institute in London, a (Polish) biochemist, Casimir Funk  (1884-1967) isolated a substance that he  named  “vitamine” because it was an amine and was necessary to be in the diet of chicken to save the animals from a deadly inflammation of their nerves  (a neuritis). Vitamines became vitamins when other essential substances were scientifically discovered and they were not amines by chemical nature. Scientists began to name them A, B, C in the order in which they were discovered except  Vitamin K which was named by Henrik Dam, a Danish scientist, to signify its role in “Koagulation”.  However the story of vitamins is an interesting scientific story which we shall look at as we talk about vitamins. It actually dates back to ancient times.

    Vitamins and minerals all variously play roles in maintaining a healthy body.  They are important for body (including brain) functions such as generation of cells, cell and tissue repair, defence against disease, energy production, etc.

    Vitamins are nutrients.  Generally, the body does not produce them.  They have to be obtained from the diet. Only a minute amount of any vitamin is needed by the body daily.

    There are two classes of vitamins: fat-soluble vitamins and water-soluble vitamins. Fat-soluble vitamins can be stored in fat cells in the body.  Fat soluble vitamins include vitamins A, D, E and K and consuming high amounts of such vitamins leads to their accumulation in the body and a disease call hypervitaminosis (hypervitaminosis A, hypervitaminosis D, hypervitaminos E, or hypervitaminosis K).  Water soluble vitamins include the many B vitamins and vitamin C.  Water-soluble vitamins are not stored in the body and must be supplied in our nutrition continually. They are extracted from food and utilized and the excess water soluble vitamins are expelled from the body through excretion, mainly in urine. When a person fails to eat or is malnourished, he or she will automatically lack water soluble vitamins.

    Since ancient times, substances present in food have been identified to be important for health such that if they were lacking in the diet a disease will result.  A classic example is scurvy, a disease that was common amongst sailors of the renaissance period because they went sailing for long periods during which they ran out of fresh foods and survived on preserved foods.  It was discovered that lemons and limes could prevent scurvy.  This is because citrus fruits contain vitamin C.  In recent times, cancer, the deadly disease that ravaged mankind at the end of the twentieth century and is still menacing is being relooked at as a deficiency disease.  A lack of vitamin B17 may be the cause of cancers and a hot debate is on in the scientific community to resolve this issue.  It is found in pits and seeds of many fruits.  Those of you that grind your peppers whole to make soups may actually be keeping safe from cancer.  We are yet to prove this with scientific evidence.

    Next we shall look at the history of vitamins and then talk about the importance of various vitamins.  To keep healthy, make sure you eat something fresh every day, even if it is just one lime or orange or tomato, or mango.  No matter how poor a person is, he or she should manage to get some vitamins daily.  Ideally, about five different fruits or vegetables should be consumed daily.

  • Healthy responses and behaviour: manners in public life

    In discussing manners in public life we are also discussing manners in private life as manners are manners anywhere: at home, in the office, on line, on the phone, in the bank, at a meeting, at the ATM,  in the shopping mall, in the market, in the car park, in the amusement park, at the cinema, in the swimming pool, at a party, on the beach, at the bus stop, on the bus, on the train, at the airport, in a plane, on the streets, in the hospital, in court, at a business, in a factory, in a place of worship, etc.  In fact, the only place on earth where a human being does not need good manners is in the grave.

    In the past few weeks while writing on manners, I have discovered many bad manners that I have.  Now, the habits I have that are bad manners are not for telling so do not read on eagerly to find out. And do not come spying on me to find out because that will not be good manners on your part.

    I started watching my manners from the time I wake up to the time I go to sleep: bedroom manners, bathroom manners, toilet manners, kitchen manners, dining manners, living room manners, electronics use manners, driving manners, conversation manners, relationship manners, work manners, street manners, shopping manners, and I needed to pray for many more years of life to make things better.  There is so much to improve in.

    We all have manners, good, bad or a mixture of good and bad manners. Why should we care about our manners? The things we think, say, or do affect other people directly and indirectly.  Our thoughts are reflected in our dispositions, attitudes, and reactions. The things we say or do or do not say or do not do can change a person’s psychological state, can affect physiological processes in other persons, and can pitch another person towards good or evil.

    Our physiological states (such as breathing rate, heart rate, blood pressure, and mental focus, as well as our emotions and passions) are controlled or modified by hormones and chemical messengers called neurotransmitters in our nerves.  Physiologic states are dynamic and can be raised or lowered by environmental factors.  Environmental factors influence us through our senses of sight, hearing, smell, taste, and touch.  Other people’s manners are constant environmental factors that affect our senses of sight, hearing, smell, taste, and touch as well as our emotions and passions. Good manners tend to engender pleasure in other persons and bad manners tend to engender displeasure or threat in other persons.

    A brainy quote by Laurence Sterne, an Irish novelist goes: “Respect for ourselves guide our morals, respect for others guide our manners”.

    Respect is the source, the means, and the end of good manners.  Good manners is shown in respect for a person’s body, mind, spirit, name, identity, dignity, status, property, rights, freedoms, privacy, security, peace, choice, environment including personal space, resources, goals, opportunities, benefits, merits, credits, interests, relationships, life etc.

    What constitute good manners and respect for others?  Can an adult poop on your lap like a baby can do and you forgive him? In some parts of the world you have to burp to show your host you loved the food while in another part of the world, if you burp in a posh restaurant you will be dismissed.  There are many factors that guide what are good and bad manners: gender, age, culture, geography, history, education, religion, social status, and profession.  Irrespective of the guiding factors, good manners are defined by the wilful respect for others and the wilful disposition towards the pleasure and well-being of others.  It is really about sharing the world with others properly, with good will.

    As we mature in life, we would find that “The test of good manners is to be patient with the bad ones” (Spanish poet, Solomon Ibn Gabirol).

    Can good manners put a person at a disadvantage? Certainly, in a jungle.   All civilized societies cherish good manners and most civil laws are put in place to ensure good manners and the well -being of citizens.

    Good manners start from within the family.  It is good to have a family.  A good family brings out our better and our best selves.  Being able to respect and love another and to be respected and loved by another is the normal rhythm of human living.  Be it for our physical, mental, or spiritual well-being, good manners in human relationships is an essential aspect of life.

  • Healthy responses and behaviours: Relaxation

    Relaxation is a deliberate effort to break away from stressors especially normal or usual stressors such as duties and work.  It is often a break from overpowering mental states, feelings, emotions, and passions. Relaxation may also be a break from an environment or from associates.  Relaxation consists of physical relaxation, mental relaxation, and spiritual relation.  For one to become properly or totally relaxed, the three should go together.

    Relaxation diverts life from stress and harm. On the one hand, it is a control mechanism that limits the amount of exposure to stress, the duration of exposure to stress and the overall level of stress we experience. On the other hand, it is an avoidance mechanism that blocks a person from being harmed by stress.

    Relaxation techniques are numerous and may vary from a few minutes of breathing exercise to an absolute retreat.

    Relaxation is not escapism, or avoidance of responsibility or avoidance of social connectivity.  Relaxation is a means to recover, improve, re-focus, re-energize, and increase in life.  Escapism leads to dysfunction, relaxation leads to improved function.

    Family life is an important platform for relaxation – physical, mental, and spiritual.  We should take care of our families and our families should take care of us and our needs.  Unfortunately, many families end up as centres of stress.

    Relaxation can be done alone or collectively, momentarily or for a period of days, spontaneously or by guidance.  We shall discuss various ways by which we can relax.

    Before we go on to discuss how to relax, we can contemplate why we need to relax as needed.

    Why do we need physical relaxation?  We need physical relaxation every now and then because the body is finite. The body has its thresholds and breaking points. The body’s life is at its best when in a state of homeostasis or balance.  Our daily activities can cause depletion or elevation of components of our bodies and can as well produce wear and tear on various parts of our bodies.  There is a need for recovery periods for bodily repairs, rejuvenation, balancing and strengthening.  This dynamism involves all the body organs and systems: the brain, the heart and blood vessels, the eyes, the digestive system, the immune system, the hormonal system, etc.

    Why do we need mental relaxation?  We need mental relaxation every now an d then because the mind is a flux of good and evil and is easily tilted by environmental factors and experiences. Mental relaxation enables one to dominate experience and generate wilful responses of choice. Our actions are sometimes driven rather than chosen because we have not been able to exercise the mental faculty fully against environmental factors.  Environmental factors that over power our thinking could be other persons, events, propaganda, climate, finance, illness, religion, culture, etc.  Mental relaxation, even if for just a brief few seconds, helps us in rationality and avoidance of regrettable consequences of our living.

    Why do we need spiritual relaxation?  We need spiritual relaxation to connect us or to keep us connected with our origin and our end, the meaning of our lives and the consequences of all we are and do in life. Much of our stress in life and the sufferings and pains we experience are from lack of spiritual positioning and relaxation.

    There is ample reason for learning the art of relaxation.  A little bit of prior relaxation – bodily, mental, or spiritual – may be important before leaping at an opportunity, dashing for some profit, or going headlong into a responsibility. Relaxation can save us from errors and troubles. For example, without astute relaxation, interest can become obsession, care can become fuss, and duty can become mania. Be it for the father or mother of a family, or the boss of a business, or the leader of an organization, the art of relaxation is a very important aspect of holistic health.

  • Healthy responses and behaviours: When tears are not as expected

    Crying becomes too much and even pathological when it distracts from normal life activities and normal duties and makes one dysfunctional.  It is thus necessary to be able to control one’s crying by avoiding encounter with overwhelming stimuli, walking away from overwhelming stimuli if possible, finding a suitable distraction, and by mental balancing: using positives (prayer, counselling, music, fun and pleasures, change of companions, change of environment, change of activity, writing a diary, etc.) to counteract negatives (fear, anxiety, distress, loss, anger, hatred, etc.).

    Excessive crying can be a sign of a mood or personality disorder.   “Crying spells, crying over nothing at all, or crying about small things that normally wouldn’t bother you may be signs of depression” (https://www.webmd.com/depression/depression-disguises#1).

    While crying has clear beneficial effects in healthy persons, crying may not have the same beneficial effects in patients with mood disorders and may even have an opposite effect, but there are conflicting information on this matter.  Some people under depression have successfully used crying to improve their mood.

    Pseudobulbar affect (PBA) is described as pathological crying and laughter. It is also referred to as emotional incontinence.   “PBA is a condition that causes uncontrollable crying and/or laughing that happens suddenly and frequently. It can happen in people with a brain injury or certain neurologic conditions.  A person having a PBA crying spell may cry when they don’t feel sad or when they only feel a little bit sad. Someone having a PBA laughing spell may laugh when they don’t feel amused or when they only feel a little bit amused” (https://www.pbainfo.org/about-pba).

    Familial dysautonomia is a genetic disorder that affects the development of autonomic nerve cells which control involuntary actions including production of tears.  Symptoms may include insensitivity to pain, unstable blood pressure and body temperature, lack of overflow tears and poor development. The affected person has alacrima or lack of overflow of tears during psychic or emotional crying.

    Babies normally cry more than adults.  Some crying disorders are observed in some babies.  Known infant pathologic conditions of crying include cri-du-chat syndrome and baby colic.

    Cri-du-chat (French for cat’s cry) syndrome is also known as 5p- (5p minus) syndrome.  It is a chromosomal condition due to a missing piece of chromosome 5 in the genetic composition of the child. Infants with 5p minus cry with a sound like a cat’s cry.  This type of human infant cry is caused by problems in the larynx which contains the vocal cords and problems in the nervous system.  About a third of such children lose the cry by the time they reach 2 years of age.

    With primitive African beliefs, superstitious dumping or killing of suspicious children that are regarded as witches is partly because of unexplained medical conditions such as Cri-du-chat and baby colic. Other confusions come from the fact that a cat may cry like a baby.  “Generally, female cats (or queens) make baby cries at night when they are in heat i.e. when the queens are fertile and ready to mate. The sound made in the mating season is a long howl or moan, similar to that of a crying baby. Usually it is the voice of the cats in their breeding condition” (https://www.quora.com/Why-do-cats-sound-like-a-crying-baby-at-night). Thus cat and baby superstitions abound and within illiterate environments can lead to disaster for some children.

    Baby colic  is excessive crying of an infant. The crying has no obvious cause but may be due to lack of adaptation to environmental stimuli. Baby colic is generally described by the rule of three: the crying lasts three hours, occurs at least three days a week, and persists for at least three weeks in a row. Experts estimate that 1 out of 5 babies become colicky. The crying starts suddenly and has no apparent cure though some parents use colic drops and other aids. The episodes may peak in about six weeks and disappear by three months of age.

    Change in position may help.  The baby may calm down if the parent lays the baby on its tummy across the parent’s stomach or lap and the parent rubs the baby’s back which soothes and helps baby to pass gas. Some parents give the baby a pacifier to suck or put a warm bottle on the baby’s belly or put baby in a warm bath or give it a gentle massage. The baby may be swaddled and laid on its back in a dark quiet room.  A colicky baby seems to cry more than any other human and requires a lot of fuss.

  • Healthy responses and behaviours: Crying

    I am in Lagos, Tues Jan 23 2018 and I wake up at 3.30 am to go to ease myself.  I look at my cell phone for time.  I see an unsolicited text message from 2221.  I look at the thread: Fuel; we don’t have supply Mon 14.53; Ten killed, dozens injured in Borno under-aged suicide blasts 1/18 15.02.  There were previous killing news.  People are groaning: “Cry, the beloved country”.

    Crying is a physiologic response to pain: physical pain, mental suffering (such as sorrow); or spiritual suffering (such as distress).  We all feel physical pains: such as itching, burning, and aches.  We all feel mental suffering such as heart break, loss, failure, regret, shame, lack, deprivation, and desperation.  We all experience spiritual suffering such as distress, empathy, sympathy, want, and agony.

    The physiologic response to pain involves release of tears from the eyes (lacrimation).  Lacrimation can be induced by onions and noxious stimulants by direct action on the eyes or through inhalation and irritation of the mucous membranes.  A girl once told me how her mum told her and her siblings to rub a menthol balm on their eyes to help them to release tears when their wicked father died so that the father’s people might not accuse them of murder.  They did not kill him but they were relieved and not sad when he died. Crying is more than lacrimation.

    Crying is a complex physiologic mechanism involving the face and facial expression, the respiratory system and breathing patterns, secretory mechanisms including tears from the eyes and mucus from the nose, as well as the muscular-skeletal system and specific demonstrations as we see when a child goes into a tantrum or an adult experiences a  sudden catastrophe.

    Crying is an overt response, a signal to the surrounding (e.g. other humans, a child’s parents) that something is wrong or unacceptable.  It makes a natural connection that engenders a social response from sympathy to support.  When we cry alone, the benefits of crying are limited.

    Crying is a complex response.  The brain and many nerve pathways, voluntary and involuntary, are involved and many hormones are released during crying. The mental and spiritual capacities are involved.  The feelings, emotions, passions, and the heart (the capacity to love or hate) are all involved.  It means that to be able to cry well, we need to be fit and healthy in body, mind, and spirit.  Inability to cry is unhealthy.

    Crying is a social response. It calls for attention. It is contagious. It initiates bonding with other human beings. It generates spiritual connections and propagates sympathy, empathy, and compassion.

    They say grown men don’t cry.  They do.  They just have a higher threshold for crying than women generally have. Crying can get in the way of action and men, especially young men, are hormonally wired for emergency action. Inability to cry may be a danger with men that are leaders.  Leadership cannot afford to be slow in sympathy, empathy, or compassion.  In family life, we thus have two leaders: a man and a woman.

    Sometimes we do not know how to cry or have forgotten how to cry.  If we look back and look now, we see that all the world’s greats cried for something.  Jesus wept over Jerusalem. President Obama cried when a mad man went on a shooting spree on children in a school. Many songs that we sing are from people who felt pain, sorrow, or distress.

    Inability to feel pain, sorrow, or distress at other people’s miseries is a psychic paralysis.  We ca see disaster upon disaster: cheating, injustice, oppression, victimization, rape, terror, poverty, deprivation, disease, kidnappings, accidents, deaths – without sighing, without crying.

    The popular stories of the Bible tell us about Jesus’ heart.  One day, after preaching for long, he refused to allow the people (thousands) to leave without being fed because they may faint on the way.  His baffled disciples did not have food and saw no sense in his objection. The people got fed and there were left overs.

    Sorrow and compassion, bring miracles out of good leaders.  Where there is a will, there is a way. Celebrity sympathy may be common but the world always needs sincere empathy. Lack of sorrow, hardness of heart, blindness of vision, failure of will power – are all part of the syndrome of psychic paralysis. The poem “Leisure” by W. H. Davies says “What is this life, if full of care, we have no time to stand and stare”.  If we do not observe, we may not empathize.

    History tells us that one reason why misery abounds is that there is a class that allows it and sometimes is guilty of it. The danger with being elite is that the elite can be so absorbed with their own good life that they cannot observe misery; they don’t shake, they don’t shiver, they don’t shudder at the site of misery, and certainly, they don’t cry.  To be continued.
