The most common form of arthritis is Osteoarthritis and Rheumatoid arthritis.
Osteoarthritis is a joint inflammation that results from cartilage degeneration and can be caused by aging, hereditary, and injury from trauma or disease. It can damage any joint, but most commonly affects joints in your hands, knees, hips, and spine.
Rheumatoid arthritis (RA) is an autoimmune disease, where our own body attacks the joints and tissues around it, that can cause joint pain and damage throughout the body. Such a joint pain usually occurs both sides of the body, i.e if the right hand is affected, most probably the left hand will also get affected.
There is no diet cure for arthritis. However adding foods that help in fighting inflammation, strengthening bones and boosting the immune system will help in improving the lifestyle to a great deal. Omega-3 fatty acids found in fish oil can reduce inflammation to a great extent. According to recent non-confirmed researches, taking a collagen peptide supplementation (or collagen hydrolysate) can also help in reducing the inflammation and even building the connective tissues (cartilage). Yet another popular supplement that claims to relieve pain is glucosamine, however, the effectiveness of this is controversial.
