Diet • In mammals carbohydrates and fats are needed in relatively large quantities as energy source, and • proteins for growth and repair. • Vitamins and minerals are required in much smaller quantities for a variety of specific functions. • Water is a vital constituent of the diet and • roughage is necessary for preventing constipation.
Carbohydrates and fats (energy requirements) The energy required by an organism varies with age, sex, size and activity. Ideally 2/3 from carbohydrates and 1/3 from fats. A high intake of fats, especially saturated fats, is a contributory factor in causing heart disease.
Proteins Main function: as a source of amino acids which are used to synthesized new proteins Plants are able to synthesize all their own amino acids but animals are more limited. Thus man requires essential amino acids in the diet. Although plant food contains proportionately fewer proteins, a properly balanced diet can nevertheless provide all the essential amino acids.
Vitamins These are group of organic compounds with the following features:
1. No energy value
2. Essential in very small quantities for maintenance of good health
3. Not structural materials in body
4. Work as co-factors in enzymatic reactions
Two groups of vitamins:
A. Fat soluble vitamins and B. Water soluble vitamins
Too much vitamins, e.g. vitamin A, may be harmful to our body.
Vitamins B & C are water soluble; others fat soluble
Vitamin C could be destroyed by prolonged heating; tested by decolorizing deep blue colour of DCPIP; and vitamin C has relatively larger daily requirement than other vitamins.
Minerals needed to regulate the metabolism of the body essential for health needed in small amount.
Water - makes up about 75% of body weight.
- importance: as a solvent; for transport; as a reaction medium; as a reactant; dilutes wastes & poisons; forms urine.
Roughage/Dietary fibre
- consists of cellulose
- indigestible because human body has no enzyme for its digestion
- stimulate peristalsis;
- absence will lead constipation.
Milk Milk is a balanced diet for growth and development of young mammals, but it cannot sustain healthy development indefinitely because: 1. It contains little if any iron - new born baby has Fe accumulated from mother, but store becomes deficient in later life 2. It contains no roughage - constipation results with its long-term absence from diet 3. It contains a high proportion of FAT - ideal for young and actively growing organisms, but as energy demand decreases, more fat deposits around the body would increase risk of heart disease.
WEIGHT LOSS TIPS
Weight Loss Health Tip 1: For instant weight gain, exclusive milk diet is recommended in which milk is advocated to be taken after every 2 hours. So if you really want to shed some weight, 90% avoidance of milk diet is perfect for a rapid weight loss. Long absence from diet is not advisable since it is needed for growth and development.
Weight Loss Health Tip 2: New Research Suggests that routinely wearing a pedometer encourages people to walk about an extra mile, thereby lose weight and also lower their blood pressure.
Weight Loss Health Tip 3: Since the energy requirement of organism varies with activity and organism gets 2/3 of its energy from Carbohydrate then avoid eating more of Carbohydrate food at night since one is not expected to be involved in much activity during sleep hours (at night). The much of the carbohydrate ate at night add to the overall weight gain of the organism since it was not used on/for any activity. Carbohydrates are better taken during the rush hours and especially in the afternoon when one is occupied with much activity. More so if one is interested in losing weight little quantity of carbohydrate per meal during peak time is advocated. The logical effect of this is that with little quantity of carbohydrate taken during this time one is engaged in be hive of activity; the accumulated fats will be diverted to meet up with the energy requirement of the organism by providing energy to the body system.
Weight Loss Health Tip 4: If u want to have good metabolism,toxin free body then drink lot of water as water aids in digestion & muscle recovery In addition to the above Health ethics, a non habitual and non abusive use of weight loss supplement could work for people who are not discipline in the natural dietary specification needed for a positive, resultant and constructive weight loss.
