For many people, “eating better” is an intimidating and abstract concept. What counts as healthy? Is calorie counting necessary ? Is all junk food off limits? This confusion is familiar to many people, but improving your nutrition doesn’t always have to mean a diet overhaul. In fact, sometimes small changes can make the biggest impact. In honor of National Nutrition Month this March, TIME asked registered dietitians for five quick and easy diet resets that will put you on the path to better health. Embrace fat. “Most people think all fats can negatively impact health. But in reality, unsaturated fats—monounsaturated and polyunsaturated, i.e. omega-3 fatty acids —are known as the “good fats” and have been shown to reduce inflammation and aid in heart health. Some great options to incorporate into your meals and snacks include nuts, seeds, avocados, fish (like salmon) and vegetable oils, like olive and canola.” — Stephanie Perruzza, registered dietitian and health and wellness special
