Fats often have a bad reputation among most people. They are, however, essential to bodily health. They protect vulnerable parts of the human body. Fats disseminate vitamins A, D, E, and K, keeping the hair and skin healthy. They play a key role in maintaining warmth in the body.

Eating foods that contain a higher level of unsaturated fats than saturated fats can contribute to a reduction in blood cholesterol levels.
