Fatty fish

Oily fish, like salmon, mackerel, tuna and sardines, are high in omega-3 fatty acids, which have been shown to help reduce inflammation. To get the benefits, however, you need to eat fish several times a week, and it should be cooked in healthy ways: In a 2009 study from the University of Hawaii, men who ate baked or boiled fish (as opposed to fried, dried, or salted) cut their risk of heart disease by 23% compared to those who ate the least.

Whole grains

Consuming most of your grains as whole grains, as opposed to refined, white bread, cereal, rice, and pasta can help keep harmful inflammation at bay. That’s because whole grains have more fiber, which has been shown to reduce levels of C-reactive protein, a marker of inflammation in the blood, and they usually have less added sugar.

Dark leafy greens

Studies have suggested that vitamin E may play a key role in protecting the body from pro-inflammatory molecules called cytokines—and one of the best sources of this vitamin is dark green veggies, such as spinach, kale, broccoli, and collard greens. Dark greens and cruciferous vegetables also tend to have higher concentrations of vitamins and minerals—like calcium, iron, and disease-fighting phytochemicals—than those with lighter-colored leaves.

Nuts

Another source of inflammation-fighting healthy fats is nuts—particularly almonds, which are rich in fiber, calcium, and vitamin E, and walnuts, which have high amounts of alpha-linolenic acid, a type of omega-3 fat. All nuts, though, are packed with antioxidants, which can help your body fight off and repair the damage caused by inflammation. Nuts (along with fish, leafy greens, and whole grains) are a big part of the Mediterranean diet, which has been shown to reduce inflammation in as little as six weeks.

Peppers

As opposed to white potatoes or corn, colorful peppers, tomatoes, squash, and leafy vegetables have high quantities of antioxidant vitamins and lower levels of starch.Bell peppers are available in a variety of colors, while hot peppers (like chili and cayenne) are rich in capsaicin, a chemical that’s used in topical creams that reduce pain and inflammation. Peppers, however, are nightshade vegetables—which some doctors and patients believe can exacerbate inflammation in people with rheumatoid arthritis.

Tomatoes

Tomatoes, another nightshade veggie, may also help reduce inflammation in some people. Juicy red tomatoes, specifically, are rich in lycopene, which has been shown to reduce inflammation in the lungs and throughout the body. Cooked tomatoes contain even more lycopene than raw ones, so tomato sauce works, too.
