Since the gluten protein that causes reactions in people with gluten sensitivity only occurs in wheat, rye, and barley, most soy products should be safe.
However, due to the fact that many soy crops are grown around wheat crops, the soy can potentially be cross contaminated with gluten. Naturally, soybeans and other legumes are gluten free.
What To Look Out For
Although the majority of soy milk on the market is safe for those with celiac disease to drink, some choices are better than others. Even if soymilk is gluten free, many with celiac disease have damaged GI tracts. Some soymilk contains ingredients that can irritate them further. To avoid this, make sure that the soymilk you buy is Certified Gluten Free.
Health Benefits
Soymilk is a good option for those who are lactose intolerant. An 8oz glass contains on average of 100 calories, 8 grams of carbs and 7 grams of protein. It contains 4 grams of fat and .5 grams saturated fat, so it is also a good choice for low fat diets.
