Nutrients, their types and their roles

What are Nutrients?

Nutrients are the essential components of life, which are extremely important for human beings to lead a healthy and fit life. Nutrients are nothing but, certain chemical substances, which are present in some or the other foods that we consume.

Classification of Nutrients

Foods can be classified into three types, based on their nutrient content as, protein rich, carbohydrate rich, and fat rich. The carbohydrate and fat rich foods should be consumed in lesser quantity, as they increase the content of fats in the body. Proteins and fats are oxidized in order to produce energy. Nutrients include chemical compounds like proteins, fat, carbohydrates, vitamins and minerals.

Vitamins and minerals are not the source of energy to the body. However, they assist the metabolic activities in the body. They also help in utilization of proximate values. Minerals are important components, which help in forming the body structure and shaping of the skeleton.

Importance of proportion

All the elements of the nutrients family are essential components of human lifecycle. It is important to have the right, proportionate balance among these nutrient components, in order to lead a healthy life. Right proportion of these elements can increase stamina and fitness. Dieting actually focuses on this concept. A right diet chart makes a framework, allowing an individual to obtain the necessary amounts of nutrients, so as to proper supply of energy throughout the body.

If only selected nutrients like fats and carbohydrates are consumed in larger proportion required, they may lead to over accumulation of fat molecules in the body. These are tough to break down as, oxidization is a slow process. These excess fats need to be burnt, in order to prevent obesity threats for future. Burning these fats is not easy. Regular and large consumption of oily items, junk food, etc, can increase the fat molecules in the body. Such people need to follow ‘Venus Factor’ training methods, in order to burn their accumulated, excess amounts of fats.

Consider them before selecting your diet chart

All individuals go through a lot of studies and posted diet charts on nutrient proportion, foods that provide nutrients, etc. People should not blindly believe on information in the blogs and forums, they should look for reviews and suggestions, before implementing or experimenting with the nutrient or diet chart. It is also a sensitive area similar to body building. As we consult various expert opinions about Venus factor, Venus factor review, and also the views and suggestions of people, who have already used or tried it. Similarly one has to consider nutrients as a sensitive issue. He/she has to consult experts, ascertain factual information and reviews before experimenting or trying out the nutrient or diet chart.

Different people, different composition of nutrients

It is important to note that dietary habits vary from each person to another. They depend on various factors like culture, location, food habits, gender, etc, thus, using a common diet plan based on single nutrient chart, would not result into an extremely positive result. Every individual has to customize their diet plan, based on their requirements and objectives.

A human body should get proper nourishment. Due to lack of knowledge or due incomplete or inadequate consumption of food, a person should not become weak, and malnourished. Thus, these concepts help in facilitating accurate information to people, in order to help them a proportionate and all round growth. People lack important nutrients because of their food habits, their food habits need to change and they have to focus more on eating healthy items, in right quantity.

People, when see an item in the high nutrient yielding category, they start consuming that item in excess quantity. It is important to realize, that any item in excess can only cause harm and not benefit.

Deficiency of Nutrients in rich

Usually it is said that, poor people, who cannot afford food suffer from malnutrition. But, it has been observed that, the rich people of the society are also suffering from many malnutrition diseases and deficiency diseases, only because of their poor eating habits. Such habits can lead to obesity. Since, all their crazy demands are being fulfilled they do not realize the importance of living fit. They consume only items, which have high content of sugar and cholesterol, at fast food centers and malls. Their parents do not have time to monitor the food habits of their children.

Wrong selection of food

This is quite common in the younger generation of today. They do not enjoy homemade healthy items and instead opt for items such as burger, pizzas, noodles, soft drinks, etc, which do not contain any proteins, vitamins, or minerals. They are loaded with only fats, which can cause severe problems to their health. Moreover, they need not work for getting anything. They relax the whole day, relishing all sorts of facilities and become lazy and inactive.

Wrong thoughts

Another thing, which brings them into spot of bother, is the attitude of young teenagers and their priorities. Young people, especially women consume extremely less food on the name of dieting, in order to maintain their shape and size and not look ugly or fat. They consume only junk foods and neglect the items, which support their diet, with the required amount of nutrients.

This set of activities can make them obese in no time. They turn into couch potatoes in extremely short period of time. The most deadly disease caused by uncontrolled consumption of these items, is diabetes. It is a disease, which has found no proper cure till now. ‘Prevention is better than cure’ and therefore, preventing such diseases by following certain good food habits is really essential. The parents have to take more responsibility and initiate good food habits in their children, in order to reduce malnutrition and obesity.

Cereals, when consumed with pulses provide the best effect on the body, as the pulses complement cereals by improving the quality of proteins, due to mutual supplementation. Cereals are rich in the contents of calcium and iron. However, cereals are deficient of minerals. On the other hand, millets are rich in mineral content and contain less amounts of protein.

Thus, sufficient amount of cereals and pulses should be taken on a daily basis, to satisfy the internal needs of the body.

Nutrient Content in Fruits and Vegetables
