NUTRIENTS Science of the nutrition based on the nutrients found in the body. Nutrients are the chemical substances supplied by the food that the body need for growth, development, maintenance and repair.
Classification of Nutrients A- On the Basis of Quantity Macro Nutrients- Required in large quantity necessary for building body structure eg:- Carbohydrate. Fat. Protein. Contd. Micronutrients - Required in small quantity necessary for body metabolism and immunity eg:- Minerals Vitamins Fibers etc
B- On the Basis of Nutrients synthesis in the Body. Essential Nutrients- Body not able to synthesize these nutrients while they are important for growth and development of body. It should be must supplied by food in the diet eg. Vitamin A, Vitamin C, Calcium etc. Non -Essential Nutrients Body is able to synthesize these nutrients no need of supplementation of food in diet eg; alanine amino acid etc.
FUNCTION OF NUTRIENTS Serve as source of energy. Support the growth and maintenance of tissue. Regulation of basic body process. These life sustaining functions collectively are the part of the metabolism, the sum of all physical and chemical changes takes place in the body.
ENERGY Energy is the capacity to do work. In order to maintain body weight energy intake must be equal to energy expenditure. Energy has various forms all food enters into as a chemical energy in the body it convert into an other forms of energy like mechanical in muscle and electrical into nerves. The energy both in the food and body measured in kilocalories. Carbohydrates', fat and proteins are energy nutrients.
Energy Balance Total energy comprises -Basal Metabolic Rate (BMR)- 50%- 75% - Physical activity 20%-40% -Diet induced thessrmo genesis 10%
Nutrients Requirement of Healthy Children's Recommended Dietary Allowances (RDA) is the intake that meets the need of 97-98 percent healthy individuals in a life stage and gender group. It does serve as benchmark. It is intended for use as goal for daily intake by individuals. Deviated from RDA create nutritional imbalance in individuals.
