Question

What is food?

Answer 1

Hint: Food is a substance that provides nutrients and energy to living organisms. Food is also defined as an edible substance which contains many different useful components like carbohydrate, fats, proteins, etc.

Complete answer:
-Food provides nutrients that make our body work, grow, and repair. Our body function totally depends on the type of food that we eat.
-Food contains many chemical substances.these can be macronutrients and micronutrients. Macronutrients are the compound that is present in a large amount like protein carbohydrates fats. Micronutrients are the compounds that are present in a small amount like vitamins, dietary foods (water, roughage).
-Food also contains color ( It may be natural or synthetic), different types of flavors, active substances like caffeine, steroids (but these chemically affect our body). The chemical nature of food also keeps changing, especially while cooking. The acidity and alkalinity represent the physical properties of food.
We eat many types of food-
Fat- fats are mainly produced by plants and animals in the organic process. Fats are insoluble in water. At room temperature, saturated fat is found to be solid while unsaturated fat is found to be liquid. We mostly consume saturated fat in the form of vegetable oils.
Proteins- it consists of amino acids joined by a peptide bond. It is very important for the proper functioning of living cells. Protein is also the soul of that animal that does not produce their energy from sunlight. In general, proteins come in two forms- complete protein and incomplete protein. complete proteins contain all the 8 essential amino acids which the human body cannot produce by themselves. Deficiency of proteins can cause fatigue, hair loss, loss of muscular mass.
Carbohydrates- they are used as a source for consuming or storing energy. Glucose, Sucrose, Fructose, Lactose, Galactose, Mannose all are carbohydrates.

Note: Hence food is the main source of energy and nutrients. It helps in keeping our body energy in balance. Nutrients are divided into three classes: Energy giving nutrients (food which provides energy), Protective nutrients (food which provides protection nutrients), and Body-building nutrients (food which provides building nutrients). The lack of nutrients can lead to various deficiencies in the body.
