Fat is actually very important to a healthy diet. You need both saturated and unsaturated fats to properly use as a fuel source and to help absorb some vitamins and antioxidants. Omega-3 fats are vital for optimal nerve, brain, and heart function. Also, healthy fats make food more flavorful and satisfying, which means you don’t need to eat as much to feel full. It is recommended to eat more unsaturated fats (like olive oil, nuts & nut butters, avocados, seeds, flax, and oily fish) than saturated fats (like meat, poultry, & dairy). Always avoid Trans-fat which is artificial fat found in partially hydrogenated oil.
