What role do fats play in the body, and what are some examples of healthy fats?

Fats are essential for various bodily functions, including providing energy, insulating organs, and absorbing fat-soluble vitamins. Healthy fats, such as those found in avocados, nuts, seeds, and fatty fish like salmon, contain unsaturated fats, which can help lower bad cholesterol levels and reduce the risk of heart disease when consumed in moderation.
