Can You Eat Tapioca on the Gluten-Free Diet?

Tapioca is not a grain at all—instead, it's produced from the peeled roots of the tropical cassava plant, native to South America. Cassava is an important source of starch and calories for people in both South America and Africa.

Since it's not a grain (gluten only occurs in the grains wheat, barley, and rye), tapioca is naturally gluten-free in its pure form. Tapioca flour and tapioca starch are ingredients used in many gluten-free products, and you can feel confident that as an ingredient in those products, it's safe for someone who has celiac disease or non-celiac gluten sensitivity.

But don't assume that every brand of tapioca you can buy in a store is automatically gluten-free—as is the case with other naturally gluten-free grain and grain-replacement products, tapioca has a high risk of gluten cross-contamination, since it's frequently processed on the same equipment as those same gluten grains.

Why Isn't Tapioca Always Safe?

To make tapioca, food processors grind the cassava root, boil it and then process it to extract the starch from the ground-up root. The little pearls of tapioca you find in tapioca pudding are the result of this process. Tapioca starch and tapioca flour generally are the same product, just with different names.

Manufacturers of gluten-free-labeled products take extra steps to make sure that gluten-free ingredients like tapioca are protected—that means they're generally not processed in the same facility (let alone on the same lines) as wheat, barley or rye grains and flours.

However, other manufacturers (those in the Far East can be offenders, although they are not the only ones) may not take these allergen-specific precautions, and it's difficult to be certain what precautions they do take by reading their packaging.

Therefore, when buying tapioca flour or tapioca starch, you should take care to stick with companies that specifically call out their products as "gluten-free," even if those products are more expensive than the more generic tapioca you may be able to find at your local Asian market.

Gluten-Free Tapioca Brands

Here's a list of companies that produce gluten-free tapioca flour or starch:

  • Big River Grains. When I need baking ingredients, I turn first to Big River Grains, a family farm in Oregon that processes only gluten-free and oat-free products and is extraordinarily careful to keep out any trace gluten. Big River Grains offers both tapioca starch and cassava flour in two and two-and-a-half pound bags.
  • Bob's Red Mill. This likely will be the most readily available source of gluten-free tapioca flour you'll find. Bob's tapioca flour is tested to ensure it contains less than 20 parts per million of gluten. If you react to gluten-free oats, you should be aware that Bob's gluten-free baking products (including the tapioca flour) are processed on the same lines as the company's gluten-free oats.
  • Ener-G. Ener-G may be better known for its tapioca-based gluten-free bread products, but the company also sells pure tapioca starch. Ener-G tests its products to ensure they fall below detectable gluten levels, currently 5 parts per million (lower numbers are always better).
  • LivingNOW. NOW may be better-known for its supplements, but its baking ingredients — including its tapioca flour—are certified gluten-free (tested to below 10 parts per million) and produced in an allergen-free, gluten-free facility. The tapioca flour is available in a one-pound bag.
  • Yes, sells nuts, but the company also sells a variety of other gluten-free products, including bulk tapioca starch in several sizes (starting at one pound). is certified gluten-free, which means the tapioca starch and the retailer's other products must test below 10 parts per million of gluten.
  • Shiloh Farms. Another retailer that's certified gluten-free, Shiloh Farms sells one-pound bags of ground tapioca starch that's sourced in Thailand and processed in a gluten-free facility.

What Else Should I Know About Tapioca?
