Is Whey Protein low-FODMAP?
Pure whey protein powder made with a whey isolate is fine on a low-FODMAT diet, but the included additives may not be. For more information you should check the nutritional facts label.
To be on the safe side, you should try to find a pure whey protein isolate which doesn’t include any additives or flavors. Do not use whey protein powders made with “whey concentrate” as these include a considerable lactose content. Whey powders made with only whey isolate do not contain lactose and have negligible carbs. These make this form of whey protein safe for use on the low-FODMAP diet.
