Why proteins, Fats, Carbohydrates, Minerals, Vitamins and Fibre are essential for health?

Everyone knows that we need food in order to survive, and the big bonus is that eating is such a pleasurable pastime. But, as with anything so enjoyable, it is very easy to get carried away, which is why, in this age of fast food and plenty of it, it is so important to stick to a balanced diet. This does not mean that diets should be boring and unadventurous, simply that what we do eat should be healthy, energy-giving and nourishing. Lets know why proteins, fats, carbohydrates, minerals, vitamins and fibre are essential for health.

The body’s needs

From a fairly simple range of foods the body can derive all he raw materials it needs to keep strong and healthy.

And, although the foods we normally eat are very varied and often far from simple, the body can break these foods down, sort them out and distribute the resulting compounds to the areas of the body where they are needed.

What is not needed becomes waste. The one thing the body cannot do, however, is to cover for us if we are not getting enough of a certain type of nutrient.

Food containing Proteins and it’s benefits to health

Proteins form an essential part of all plant and animal cells, and are required for growth and tissue repair. Proteins from animal foods, such as meat, cheese, eggs and fish, are of a higher value then vegetable proteins, such as beans and peas.

Benefits of fats and some foods containing fat

Fats provide the body with heat and energy, and prevent the skin from drying. They also promote growth by making calcium available to the body tissues. Not eating enough fats can cause a vitamin deficiency and, as a result, skin disorders.

However, an excess of fats causes indigestion and increased weight, so certain foods high in fats, such as cooking oils, butters, eggs, nuts, chocolate, pork products and oily fish, such as herrings, sardines and whitebait, should be eaten in moderation.
