Nutrition

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

Nutritional science studies how the body breaks food down (catabolism) and how it repairs and creates cells and tissue (anabolism). Catabolism and anabolism combined can also be referred to as metabolism. Nutritional science also examines how the body responds to food.

Fast facts:

  • The human body requires seven major types of nutrients.
  • Not all nutrients provide energy but are still important, such as water and fibre.
  • Micro nutrients are important but required in smaller amounts.
  • Vitamins are essential organic compounds that the human body cannot synthesise.

What is nutrition?

  • As molecular biology, biochemistry, and genetics advance, it has become more focused on metabolism and metabolic pathways – biochemical steps through which substances inside us are transformed from one form to another.
  • Nutrition also focuses on how diseases, conditions, and problems can be prevented or reduced with a healthy diet.

Similarly, nutrition involves identifying how certain diseases and conditions may be caused by dietary factors, such as poor diet (malnutrition), food allergies, and food intolerance’s.
