Read the passage below and answer questions 39 to 50.
Foodstuffs are basically divided into carbohydrates (mainly starch and sugars) protein and fats from animals or plants sources. Often, one particular source contains more than one constituent but may be predominantly carbohydrates, proteins. Vitamins and minerals, though not providing direct energy, are essential for many bodies functions. They are usually required in relatively small amounts and are obtainable from the primary food sources unless one is eating highly refined foods or there is an inability within the body to extract them from these foodstuffs. Under these conditions, supplementation becomes necessary. Therefore it is important to eat fresh wholesome foods grown in places with no known minerals deficiencies or excesses.
dy's energy requirements and supplies all the essential building blocks. These include nine amino acids (from proteins, one fatty acid (from fats) and glucose (from carbohydrates). The body has an in-built mechanism for converting types of food into different building blocks, those listed above, which together with vitamins and minerals have to be acquired from the diet.
It should be appreciated that, while food is only eaten at certain times, the body requires energy continuously. Thus, the composition of a meal should be such that it can provide energy immediately and also in a sustained manner. Carbohydrates provide energy in the short term, proteins in the medium term and fats in the long team. The same process is replicated in the body when it is using up stored food. The type of activity one is involved in also influences energy needs, people leading actual lives require more energy than those with a sedentary lifestyle. Children, pregnant women and breast feeding mothers also require more energy
The biological value of food is also important. Animals' protein has a higher biological value Act than plant protein and hence, a small portion may suffice. Unsaturated vegetable fats are also safer to use compared to animal fats. Generally, a balanced diet should supply fifty percent of energy requirements from carbohydrates, thirty percent from proteins and twenty percent from fats.
Though associated with good factors, the use of mega-doses of vitamins cannot be a substitute for energy requirements. It is especially not advisable to have a high intake of fats, soluble vitamins A, D, E and K and foods with high minerals content, especially of sodium and potassium. Where deficiency exists due to the soil type or food preparation style, supplementation via manufactured foodstuffs for example, iodized salt or fortified bread and milk, may do as a substitute.
