What is nutrition, and why is it significant?


Food is the supply of nutrients, nourishment, or aliment that organisms and cells need to survive. Nutrition is the study or practice of ingesting and utilizing foods in science and human medicine.

Nutritional science focuses on the body’s processes for breaking down food (catabolism), as well as for repairing and growing new cells and tissue (anabolism). Metabolism is another term for anabolism and catabolism put together. The body’s reactions to food are also examined by nutritional science.
