Dietary fats are essential nutrients that provide energy and support cell growth. They help the body absorb vitamins A, D, E, and K, which are important for various bodily functions. Fats can be classified into three main types: saturated, unsaturated, and trans fats. Unsaturated fats, found in foods like olive oil and avocados, are considered healthier options. Saturated fats, commonly found in animal products like butter and cheese, should be consumed in moderation. Trans fats, often present in processed foods, are linked to health risks and should be avoided. Balancing different types of fats in your diet is important for overall health.
