If your diet is low in natural fruits and vegetables it could be causing the growth of harmful bacteria which may contribute to arthritis symptoms.  Whole fruits, berries, leafy greens, and vegetables are all rich in vitamins, minerals, anti-inflammatory antioxidants like Vitamin C and E, and phytochemicals.  They are also rich in fibers that provide the beneficial bacterias that balance the gut and keep bad bacterias that cause inflammation in the body down. You should eat at least five (preferably more) servings of fruits and vegetables each day. Studies have revealed that Rheumatoid Arthritis sufferers who change their diets by increasing their fruit and vegetable consumption found their symptoms to significantly improve, and in some cases, disappear completely.  Besides consuming fresh, raw produce, you can add roasted, baked, steamed, or stir-fried produce to your diet.  Instead of cakes and cookies for dessert or snack time, try to appease that sweet tooth by consuming fruits.
