0 mg50 mg = a day79 mg+
Lower-oxalate swap: Broccoli, grade B, about 6 mg per 1/2 cup cooked.
Green beans are high in oxalate: about 72 mg per 1 cup, which is 144% of the 50 mg a day many stone clinics aim for.
If your doctor has put you on a low-oxalate diet, eat it with something high in calcium, like milk, yogurt or cheese. Calcium in the same meal binds oxalate in the gut, so less of it reaches your urine.
