The Question of Oats and Plant Milks for Gluten-free

With new plant milks like oatmilk gaining so much publicity it is time to clarify the situation. 

Let us be clear . . . oats are from grasses. And humans are not meant to eat grasses. All the poaceae species are unsuitable for humans - because we do not have the physiological equipment to digest them.

The group includes: wheat, barley, oats, rye, corn, sorghum, millet and triticale. The important thing to remember is they ALL contain proteins CALLED PROLAMINS which are extremely difficult for humans to digest.

While cattle can digest prolamins . . . they need four stomachs to do the job! 



What are these indigestible (toxic) proteins?

  • Oats contain avenin
  • Wheat, spelt and triticale contain gluten
  • Rye contains secalin
  • Barley contains hordein
  • Rice contains glutelin, albumin and others (but hardly any)
  • Sorghum contains kafirin - and
  • Corn contains zein

And remember the Australian Bonsoy brand soymilk contains barley.


Plant milks: our verdict . . .

Unfortunately the human digestive system cannot process these enormous molecules - so they process us instead.

Slow-burn damage and disruption happens throughout the body when we ingest them - and according to the science - the resulting injury to cells and organs is the precursor to many chronic diseases:

  • Diabetes, cancers, neural disorders, multiple sclerosis, schizophrenia and others  ... Learn more with the free ebook 


Is it safe to eat oats if you are Celiac?

Have you been given conflicting advice about the safety of eating oats if you are Celiac?

  • The Institute's research shows there is way too much doubt about the safety of oats - so we recommend avoidance.

To help you understand the depth of research done on the topic and published in peer-reviewed journals - we have compiled a short list of relevant papers. Click on the links to go directly to the journal abstracts. 

Each of these papers discusses intestinal mucosa damage caused by oats to those with Celiac disease – and/or uncertainty about the safety of oats in a gluten-free diet.
