Diet & Nutrition

Food and beverages provide the energy and nutrients you need to improve health, manage disease, and reduce the risk of disease. Complete nutrition requires ingestion and absorption of vitamins, minerals, essential amino acids from protein and essential fatty acids from fat-containing food, also food energy in the form of carbohydrate, protein, and fat. Dietary habits and choices play a significant role in the quality of life, health and longevity.

What Happens to the Body When we Diet?

The body starts to respond to healthy dietary changes as soon as they are made. This can be advantageous, because a diet can then eventually reduce the risk of obesity, diabetes and heart disease, as well as improve a person’s overall sense of well-being.
