ca oxalate 환자 들 이 먹 으면 안 되 는 음식 들 . . 많 은 것 순서 대로 외워야 겠 네요 Accurate information on the oxalate content of foods is much harder to come by due to the difficulties in measuring it . There is little dispute , however , that some foods such as spinach , rhubarb , peanuts , strawberries , wheat bran and chocolate contain large amounts of oxalate and should be avoided . Scientists with whom Ixion are currently collaborating have developed sensitive techniques to accurately measure oxalate in foods and some of their results follow in a Table . This Table will be updated as their results accrue . The size of servings normally eaten should be borne in mind , noting that 100 grams is about 3 . 5 ounces . A large baked potato weighing 200 grams could contain over 50 mg of oxalate , for instance . Foods providing over 20 mg oxalate / 100 g should probably be eaten in moderation .
