What foods should I avoid for knee pain?

Avoid food containing sugar, refined grains, and omega-6 fatty acids. Sugars and refined grains, such as pasta, white bread, white rice, etc., are considered the worst foods that do not aid in lowering or relieving joint inflammation. Also, overconsumption of omega-6 fatty acids can promote inflammation. Sources of omega-6s include sunflower oil, safflower oil, peanut oil, corn oil, vegetable oil, and grapeseed oil.
