Healthy Diet

Homocysteine is an amino acid derived from the metabolism of Amino acid methionine, its excessive level in the blood threaten cardiovascular health in a complex way, its use in the body depends on the level of methionine present at a particular time, it is converted to cysteine in the presence of adequate methionine and methionine in it(methionine) deficiency by the action of enzyme in the body. Homocysteine in itself is not present in food but its gotten from food sources of methionine like meat, egg, legumes e.t.c The excessive level of homocysteine can be the result of genetic defect of its metabolising enzyme or as a result of nutrient deficiency e.g vitamin B6, B12 and folate. The presence of these B vitamins in the daily consumption helps in proper elimination of excessive homocysteine derived from food or other sources. Uncontrolled level of homocysteine can reduce flexibility of vessels  or damage endothelial cell hence inhibiting proper flow of blood and effectiv...

                Introduction Phytochemicals are groups of non nutrients plant's colour presents in food or as supplement which are biologically active in the body. They are widely present in plant food such as fruit, vegetables, herbs and spices. Some examples of phytochemicals are Lycopene present in tomato Limonene present in citrus fruits Catechins present in teas Dially sulphide present in ginger/garlic. Quercertin present in apple e.t.c. Phytochemicals, when adequately present in the diet delivers a wide range of benefit in the prevention of some chronic diseases like; Cancer Diabetes mellitus Cardiovascular diseases and lot more.   Dietary choice Phytochemicals content of the diet can be increased with diet rich in fruits (like apple, citrus), vegetables especially green leafy ones, legumes like soy e.t.c.    Lycopene is responsible for the red colour of tomato, it is an healthy source of this phytochemic...

Introduction Free radicals, chemically are refer to as atom/molecules that have one or more unpaired electron, this unpaired electron makes them highly reactive. Actions of free radicals is harmful to the body system initiating a lot of chronic diseases like cancer, cardiovascular disease, diabetes mellitus e.t.c. How are free radicals generated ? Free radicals are of different types ranging from reactive oxygen species like superoxide radicals to nitrogen species. Superoxide radicals are generated during exposure to certain chemicals or drugs, they are also generated during activation of White blood cell. Hydrogen peroxide, though though not a free radicals is consider harmful to the body at a high level. It is generated during an ascobate reaction, and also during oxidation of long chain fatty acid. Hydroxyl radicals are generated during exposure to high heat where water components of the cell are broken down into hydroxyl and hydrogen ion. Damage by free radicals ; Fr...

INTRODUCTION ; Sodium, a macromineral present naturally in food play a good role in the body some which include Fluid balance Muscle contraction Nerve transmission High intake of sodium has a direct link with hypertension. It's often thought that the only way of reducing the intake of this macro mineral is to reduce the use of table salts but sodium is also present in other chemicals used in food industry, and some home preservatives all which can increase the intake of the ion unaware. Some of those chemicals among others are; Monosodium glutamate ( MSG): it is used in food preparation, canning and frozen of foods. Sodium arginate : this chemicals is used in chocolate milk and ice cream for smooth texture. Sodium hydroxide : it is often used in food processing to soften and loosen skins of certain fruits and vegetables. Brine : a water-salt mixture often used in food preservation to prevent growth of bacteria. Disodium phosphate: its present in some cheeses. SOL...

Introduction ; Goitrogens are chemical substances present in some foods like vegetables,fruits and seeds which interfere with iodine metabolism preventing the synthesis of thyroid hormone. Some iodine deficiency are not as a result of low dietary intake but are as a result of the presence of Goitrogens in the diet which inhibit their uptake in the gland. Sources; foods high in sulphur are generally high in goitrogens. Some of the goitrogenic foods are Vegetables ; kale, collard green, egg plants, cabbage, broccoli, okra e.t.c Fruits ; grapes, figs,peaches, plums e.t.c  Seeds ; flaxseed,pumpkin seeds e.t.c Nuts ; almonds, peanuts, walnut e.t.c. Some of this food have goitrogens originating from pesticides and other chemical used during the cultivation of the plant. Solution ;  Thyroid health can be improve by effective and controlled Iodine supplementation with a decrease Goitrogenic foods intake.  This is beneficial as more iodine is available to m...

Introduction Hyperlipidemia is a disorder characterized by high fat level in the blood. It is an indication of high fats diet especially saturated one coupled with low to no physical activities in adults. Because of high serum lipid associated with this condition, the blood vessel got clogged up and increase the pressure in the affected vessels hence gives rise to high blood pressure. Overtime, some of the excess fats accumulate in the abdomen leading to abdominal obesity all which posses threat to the healthy functions of many organs. Solution Diet though not the only therapy play an important role in preventing this disorder. Reduced cholesterol intake to less than 200mg/day in adults diet prevent the disorder, limiting saturated fats and trans-fats content of the diet and increasing polyunsaturated and monounsaturated fatty acid in the diet is also a good prevention measure. All this can be achieve by decreasing the following food groups Fried foods Coconut Butter ...

Introduction: The brain like any other part of the body responds to both genetic and environmental factors that can enhance or diminish its amazing capacity during the process of ageing. Ageing can decrease blood supply to the brain and reduce brain cells, a condition which can affect the cognition of the brain. Requirements; Proper functions of the brain depends on some chemicals called neurotransmitter example of which are serotonin and norepinephrine. Synthesis of these chemicals directly depends on some nutrients like   Protein-amino acid e.g tryptophan.   Vitamins e.g vitamin C. Minerals e g copper. Fatty acid e.g omega-3 and 6. Vitamin C and copper are responsible for hydroxylation of amino acid tryptophan for the synthesis of serotonin for healthy functions of the brain. A high protein diet of high tryptophan content supplement with vitamin C is required for healthy brain functions and prevent some associated disorder. Omega-3 fatty acids are t...

Introduction ;  Ageing process in older people bring about many physiological changes some of which are; Loss of muscle Inadequate dentition and difficulty during swallowing. Decrease sensitivity to taste and smell Decrease in firmness of intestinal muscle Constipation and diarrhoea Requirements ; Carbohydrates, proteins, fats vitamins and minerals should be properly formulated for older people to allow good health. 1. Proteinous food of high quality should be consumed because of decrease in calorie requirements during this stage for good immune system and for tissue and muscle building. 2. Carbohydrates majorly complex ones should be encourage to spare protein from being used as an energy source. Fibre content of the diet should be increase to allow proper movement of intestinal muscle and prevent constipation. 3. Fats should be enough to enhance flavor and provide valuable nutrients but should be limited to saturated fats so as as to prevent excess cholesterol whi...

Introduction: Acidic foods are foods which contains some cations like Ca, mg, k, and others which make the end product of digestion of the food acidic and increase the acidity of the body. On the other hand, alkaline food produce alkaline reactions in the body after digestion. Examples Acidic foods : fish, meat, cheese, eggs, legumes and grains Alkaline foods: fruits and vegetables, milk, water. Interactions ; The nutrients in foods have either an acidic or alkaline effects on the blood, while acidic foods decreases the pH, alkaline foods increases it. To keep the body in an healthy state for proper functioning of the enzyme, the pH must be at it normal state. Alteration in the normal pH values can leads to the following conditions; 1. Physical tiredness 2. Allergies 3. Low/high stomach acidity 4. Diarrhoea 5. Low thyroid and other hormones activities. Solution ; To keep the body in an healthy state for proper functioning of the enzyme system at the norm...
