Healthy eating is one of the best ways to prevent or delay health problems. Eating well, along with getting enough physical activity, can help you lower your risk of health problems like heart disease, diabetes, obesity, and more. To reach your goals, experts advise making small, gradual changes.
Experts note that the best diet to follow is one that is science-based, that allows you to meet your nutritional requirements, and that you can stick to in the long run. The main source of science-based nutrition advice is the Dietary Guidelines for Americans. These guidelines describe which nutrients you need and how much. They also point out which ones to limit or avoid. Every five years an expert panel reviews all available scientific evidence regarding nutrition and health and uses that to develop the dietary guidelines.
