Is almond milk high in oxalate?

Lower-oxalate swap: Oat milk, grade A, about 3.6 mg per 1 cup.

Almond milk is high in oxalate: about 27 mg per 1 cup, which is 54% of the 50 mg a day many stone clinics aim for, or 27% of the 100 mg others allow.

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. How much calcium, and what if you don't eat dairy.
