Research suggests that certain foods boost inflammation, while others lower it. Foods high in omega-3 may help lower it. Inflammation is a normal immune system response to infection and pain. But if it lasts too long, it may lead to health problems like heart disease, and back and joint pain. So be sure to get enough healthy fats in your diet. While you’re at it, add fruits and veggies of many colors to your food plan. These have compounds that may help quell inflammation, too.
