A healthy diet is believed to play a role in warding off chronic inflammation that can lead to chronic diseases such as diabetes, cardiovascular disease, cancer, and cognitive decline. Six types of foods that may help fight chronic inflammation are berries, fatty fish, leafy greens, nuts, seeds, and tomatoes. These foods are all found in a Mediterranean-style diet, which consists of fruits, vegetables, legumes, whole grains, nuts, seeds, lean proteins, and small amounts of dairy foods and olive oil.

Many studies suggest that fiber-rich diets may help prevent heart disease. But most Americans eat only about 16 grams of fiber a day-far less than the recommended amounts.

Nuts and seeds are tiny packages of dense nutrition. They include protein, fiber, healthy fats, and many vitamins and minerals. For example, peanuts and pecans contain lots of B vitamins; almonds are rich in calcium and vitamin E; walnuts have lots of folate, vitamin E, and alpha-linoleic acid (ALA, an omega-3 fatty acid). And all nuts have magnesium. To add more nuts to meals, sprinkle a few into salads, sauces, vegetables, or whole grains such as brown rice or quinoa. Limit nut and seed intake to an ounce or two per day.

A 2023 study suggests eating more prebiotics-compounds found in plant fiber that nourish healthy bacteria in the gut-may affect the brain's reward network in a way that helps people make healthier food choices.
