Fats
Fat is an important part of a healthy diet and a rich source of energy that produces more than double the amount acquired from either carbohydrates or proteins.
It is also a carrier for fat-soluble vitamins such as A, D, E and K—which are fundamental to maintaining good health.
The problem is, not all fats are the same! The key to following a healthy and well-balanced diet it is not to exclude fats completely but to choose the good ones over the bad.
