Science of 7 Nutrients for Youthfulness


Every part of our body is composed of various type of cells, the fundamental unit of life. At maturity, the estimated average number of cells in the body is given as 37.2 trillion. From birth till child becomes adult, the number of cells gradually increases which denotes the growth in child. Once the child attains adulthood and moves towards the next phase of life by growing older, the number of cells starts decreasing and the normal functioning of body start getting hampered.

Nutrients are vital for good health. There are 7 nutrients i.e. Water, Carbohydrate, Fat, Protein, Vitamins, Minerals, and Fiber which have specific functions in our body. Generally it is seen that consumption of carbohydrates and fats are very high among general population and intake of protein, vitamins, minerals and fibe (PVMF) are very less.


Water – A non-nutrient but needed in adequate amount for transportation of nutrients in the body and to remain healthy. Minimum 2 ltrs of water is required on daily basis.

Carbohydrate – Forms a major part of diet and provide energy. 1 gm of Carbohydrate gives approx 4 Kcal.

Fats – Help in vitamin absorption and stored body fat is used during starvation for survival. But excess of fat is also harmful for our body. 1 gm of Fat gives 9 Kcals. Avoid Trans Fat, it can lead to various chronic disease. Avoid all types of Chemically Refined Cooking oil. You can refer my other blog on facts about Cooking oil (Cooking Oil – Some Facts and ??). Use Physically filtered or refined oil. Physically refined Rice bran oil is been recommended by many doctors now a days.

Protein – (Macro-nutrient)Major part of all body structures and help in growth, development, repair of damaged tissues and maintenance. Generally a person should consume 1 gm Protein equivalent of 1 kg of weight, if he/she is 60 kg in weight then he/she should consume 60 gm of Protein. Our in general diet does not contain that much of protein. Cells are mainly made up of Protein. Protein is useful in new cell formation, repair of existing cell.

Two types of Proteins,

Complete or First Class Protein – Isolate Soya Protein, Whey Protein PDCAS score 1

Second Class Protein – Different Daals (Lentils), nuts, leaf vegetables PDCAS score less than 1

Vitamins – (Micro-nutrient) It has important functions in the body like utilization of macro-nutrients and protective functions.

Minerals – Regulate body metabolism and protect against illness.

Fiber – Plays an important role in improving constipation, blood glucose levels and cholesterol levels and keep the digestive system healthy.


Our normal Diet does not contain enough of Protein/Vitamins/Minerals/Fiber (PVMF).

WHO (World Health Organisation) and Indian Council of Medical Research have specified an optimum quantity of Protein, Vitamins, Minerals, Fiber etc in the daily diet which is call Recommended Dietary Allowance (RDA). Taking each of these nutrients in an amount equivalent to their specified RDAs in our daily diet is necessary for good health.

Nutrition Supplement mainly herbal plays a vital role in completing daily requirements.

The Body has different parameters to be measured for healthy life, please refer my blog (Healthy Lifestyle – Human Body and Different Parameters)
