Nutrition is the science that interprets the interaction of nutrients and other substances in food in relation to maintenance, growth, reproduction, health and disease of an organism. It includes food intake, absorption, assimilation, biosynthesis, catabolism and excretion.

Good nutrition is eating food that has all the nutrients necessary for your body. These include: vitamins, proteins, carbohydrates, and fat. There are many benefits of taking a good diet. These benefits include:

The nutrients found in food support the activities that you engage in your day-to-day life, protect your cells from environmental damage, and repair cellular damage. Proteins in your diet repair injured tissues and promote a healthy immune system. Carbohydrates and fats provide the body with the energy that it needs to carry on with its activities. Vitamins and minerals are distributed to all parts of the body supporting the body processes.
