One in every five Americans has arthritis. Foods that have trans fat, saturated fat, simple refined fat and carbohydrates make the inflammation of arthritis worse. If you are overweight, that extra weight will put unwanted stress on the joints. The extra fat is believed to also send out hormones and chemicals that will increase the inflammation process. To help relieve the stress and pressure of arthritis, it is recommended that you eat healthy and stay in good physical shape.
