Dietary fats come in several types, and each plays a different role in how the body functions. Saturated fat, trans fat, monounsaturated fat, and polyunsaturated fat are the main categories found in food. Some fats are used for energy, support hormone production, and assist in the absorption of certain vitamins. Others are more processed or structurally different, and their impact on heart health and cholesterol can vary. Common sources of dietary fat include oils, nuts, dairy, meats, and packaged snacks. Balancing fat intake—rather than avoiding it altogether—is key to a healthy diet. Health professionals often recommend focusing on the type and quality of fat consumed rather than cutting all fat out. Understanding the distinctions between fat types can help you make better food choices that support long-term wellness, cardiovascular function, and sustained energy levels.
