Dietary fats play a vital role in overall health by providing essential fatty acids necessary for bodily functions. They are important for cell membrane integrity, hormone production, and absorption of fat-soluble vitamins (A, D, E, and K). Healthy fats, such as those found in avocado, nuts, and fish, can support heart health by lowering bad cholesterol levels. Additionally, fats serve as a concentrated source of energy and are crucial for inflammation control. It's important to balance fat intake, focusing on unsaturated over saturated and trans fats to optimize health benefits.
