Soy, a crop originating in Asia, is rich in protein and amino acids, also containing anti-inflammatory and antioxidant properties within. It can be eaten in bean form, made into soybean oil, or even found in soy milk, yogurt, butter, or nuts. Adult osteoarthritis patients can greatly benefit from including soy in their diet, since they, like fish, are quite high in omega-3 fatty acids. Soybeans also contain lots of protein, are low in fat, and contain fiber, which makes them an overall healthy inclusion to most diets. However, individuals with arthritis should still not go over the recommended daily amount, which is twenty to eighty grams of soy protein, as too much soy can have negative consequences. Those with rheumatoid arthritis should also be sure to avoid consuming too much soy.
