Control the calories in your diet to maintain a healthy body weight. Add foods like ginger, garlic, fish, nuts, berries, colorful fruits, and leafy vegetables to your diet as they are helpful against arthritis as they have an anti-inflammatory effect. Avoid excessive salt, sugar, processed and refined foods, and saturated fats, which can increase inflammation in the body. Keep your blood sugar in check because diabetes increases the risk of osteoarthritis. Well-controlled blood sugar levels can prevent the development and progression of arthritis.
