You can’t always prevent arthritis, but there are a few healthy habits you can practice to reduce your risk. One thing you can do is consume more fish. Fish are rich in omega-3 fatty acids, a healthy polyunsaturated fat. Omega-3s have several health benefits, and they can reduce inflammation in the body, lowering your arthritis risk. You should also focus on exercise, which not only takes the stress of excess weight off your joints, but also strengthens the muscles around the joints. Try your best to avoid injury. When you injure your joints, you can damage the cartilage and cause it to wear out more quickly.
