Arthritis is a degenerative disease of the joints, which causes swelling and pain that can range from mild to excruciating. Although there are more than 200 diseases classified as "arthritis", most arthritis conditions fall into one of two categories: osteoarthritis and rheumatoid arthritis. Osteoarthritis is the most common form of arthritis and affects millions of people, with 80% of them are over 50 years old. Pain and inflammation occur when the cartilage that protects the bones from rubbing against each other wears out. Rheumatoid arthritis is caused by an inappropriate immune response, in which white blood cells attack and destroy the cartilage of the joints and can even affect the bones and muscles or even the skin of patients.
Underlying factors for both of these conditions can include poor digestive function (intestinal permeability), hormonal imbalances, nutritional deficiencies, food allergies and intolerances as well as various lifestyle factors.
