I think most of the people know about nutrition, but proper knowledge about nutrition can help you to choice right foods, especially nutritious foods. Nutrition is the science of food.The nutrients and other substances there in, their action, interaction and balance in relationship to health and diseases. The process by which the organism ingests, digests,absorbs,transports and utilizes and disposes of their end products. In addition, the nutrition must be concerned with social, economical,cultural,physiological implications of food and eating.
Now lets go, know about nutrient. Nutrient is the any chemical substance contain in food that performs one or more of the functions of food this termed as nutrient.Chemically nutrient divided into two types, these are.
Macro nutrients, which are needed by body in relatively large amount. They include- carbohydrate, protein, fat and minerals(calcium, magnesium, potassium). The three functions of macro nutrients are-
provide energy,
promote growth and development of body tissues and
regulate body functions.
The main function of macro nutrients is to provide energy, counted as calories. While each of the macro nutrients provides calories, the amount provided by each varies. Carbohydrate provides four calories per gram, protein also four while fat provides nine. For example, if the Nutrition Facts label of a given food indicates 12 g of carbohydrate, 2 g of fat, and 0 g of protein per serving, the food then has 12g carbohydrate x 4 calories = 48 calories þ 2 g fat x 4 calories = 8 calories for a total of 48 þ 8 calories = 56 calories per serving).
Macro nutrients also have specific roles in maintaining the body and contribute to the taste, texture and appearance of foods, which helps to make the diet more varied and enjoyable. This is most important for regular diet. As well as maintaining a healthy life or disease free life.
Micro nutrients, which are needed by the body in relatively small amount. They include-vitamins, essential fatty acids, trace elements (chloride, phosphorus, iron, iodine, boron, copper, cobalt ). With the need of macro nutrients you need to take micro nutrients. Which is essential for maintaining a strong body, mental sharpness, fight off disease, and bear healthy children. Deficiency of micronutrients has high burden of infection and parasites. Deficiency of micronutrients also affects the health and function of individuals. The economic and social development of communities and nations can affect by this problem.
