Arthritis and diet:¹⁴

References:

• Acidic foods, such as tomatoes, do not cause arthritis
• Antioxidants, such as vitamin E, are effective in reducing pain and inflammation
• Omega 3 fatty acids also produce an anti-inflammatory process in the body
• Low fat and fat-free diets reduce antioxidant levels, which can aggravate rheumatoid arthritis
• Prolonged consumption of Omega 6 fatty acids may lead to arthritic flare ups
• Weight loss, if overweight or obese, can also reduce joint inflammation and arthritic flare ups
• Arthritis sufferers should eat a balanced diet, high in omega 3 fatty acids, antioxidants and with sufficient lean dairy and protein.
