Carbohydrates

The key to maintaining a healthy diet and a healthy weight is the consumption of complex carbohydrates with a moderate combination of proteins and fat. Carbohydrates are the main source of energy and in a balanced diet, should supply half of a person's daily caloric intake.

Complex carbohydrates such as whole grains, vegetables and legumes contain a large amount of vitamins and minerals and dietary fibers which help a person feel satisfied longer. Simple carbohydrates such as sugar, chocolate and sweet drinks, mainly contain empty calories - more calories and less nutrtional value.
