Is raisin bran high in oxalate?

Lower-oxalate swap: Corn flakes, grade A, about <1 mg per 1 1/2 cups.

Raisin bran is high in oxalate: about 46 mg per 1 cup, which is 92% 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.
