What is Nutrition? Why is Nutrition Important?

Nutrition, nourishment, energy, or ailment, is the supply of materials – food – required by organisms and cells to stay alive. In science and human medicine, nutrition is the science or practice of consuming and utilizing foods.

In hospitals, nutrition may refer to the food requirements of patients, including nutritional solutions delivered via an IV (intravenous) or IG (intragastric) tube.

Nutrition science studies how the body breaks food down (catabolism), and repairs and creates cells and tissue (anabolism) – catabolism and anabolism = metabolism. Nutritional science also examines how the body responds to food. In other words, “nutritional science investigates the metabolic and physiological responses of the body to diet.”

As molecular biology, biochemistry and genetics advance, nutrition has become more focused on the steps of biochemical sequences through which substances inside us and other living organisms and transformed from one form to another – metabolism and metabolic pathways.

Nutrition also focuses on how diseases, conditions and problems can be prevented or lessened with a healthy diet. Nutrition also involves identifying how certain diseases, conditions or problems may be caused by dietary factors, such as poor diet (malnutrition), food allergies, metabolic diseases, etc.

Nutrition: the study of nutrients in food, how the body uses the nutrients, and the relationship between diet, health and disease. Major food manufacturers employ nutritionist and food scientists. Nutritionist may also work in journalism, education and research. Many nutritionists work in the field of food science and technology.
