Lipids are a group of organic compounds that are important for our bodies. They include fats, oils, and waxes, and they play several key roles, such as storing energy and forming cell membranes. Lipids are hydrophobic, meaning they do not mix well with water, which is why they are often found in the form of fats in our diet. In addition to energy storage, lipids are essential for producing hormones like cholesterol and steroids. They also help protect our organs and keep our skin healthy. Foods rich in lipids include avocados, nuts, and olive oil, which provide necessary nutrients for our overall health.
