Is amaranth high in oxalate?
Yes. Very high, 111 mg per 1/4 cup dry (about 3/4 cup cooked)
Range 111 to 111 mg across 1 study, 48 g serving
Lower-oxalate swap: White rice, grade A, about 1.4 mg per 1/4 cup dry (about 3/4 cup cooked).
Amaranth is high in oxalate: about 111 mg per 1/4 cup dry (about 3/4 cup cooked), which is 222% 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.
Where this number comes from
Each row is one published measurement, converted to a 48 g serving (1/4 cup dry (about 3/4 cup cooked)). The grade and the range use the rows prepared the way the serving is eaten, and take the middle. How the grades work.
