Trust Your Oats by Dale Tenhulzen

What happens to an oat before it becomes the whole grain that reaches your breakfast bowl?
In Season 3, Episode 2 of Trust Your Oats, Trust the Hull, Dale Tenhulzen explores one of the least discussed but most important stages of oat processing: removing the tough outer hull. An oat arrives from the field with an inedible protective casing that represents roughly 28–32% of the kernel, while the nutritious groat inside makes up the portion ultimately used for food.
The episode takes listeners inside the dehulling process, explaining how impact dehullers separate the hull from the groat and why millers must carefully balance efficiency against broken or lost grain. Dale also explains why oats generally remain whole grains after processing and how steaming and kilning help prevent the natural fats in oats from becoming rancid.
But removing the hull has another important effect. Because the outer surface is exposed to field conditions, fungal contaminants and mycotoxins can become concentrated there. Research shows that dehulling can substantially reduce these contaminants—but it cannot eliminate every food safety risk, and it does nothing to remove gluten contamination from wheat, barley, or rye. That is why prevention through the Purity Protocol remains essential.
Finally, Trust the Hull looks at what happens to the nearly three pounds of hull generated from every ten pounds of harvested oats, from traditional uses such as fuel and livestock bedding to emerging research into biofuels, hydrochar, fermentation, and food applications.
The armor may come off at the mill, but the responsibility for protecting the oat remains throughout the entire chain of custody.

What can the genetic blueprint of an oat tell us about better crops, gluten-free safety, and the future of oat breeding?
Season 3 of Trust Your Oats begins by going deeper into the parts of the seed-to-shelf story that are rarely discussed. In Episode 1, Trust the Genome, Dale Tenhulzen explores the surprisingly complex genetics of the cultivated oat and what scientists learned when a high-quality reference oat genome was published in 2022.
Listeners discover why Avena sativa is such a genetic puzzle, carrying three ancestral genomes, 42 chromosomes, and an enormous sequence of more than 11 billion DNA base pairs. The episode examines ancient chromosome rearrangements that can create challenges for breeders and explains how modern genomic tools and molecular markers are helping researchers identify valuable traits such as disease resistance with greater precision.
Dale also explores one of the most important questions for the gluten-free community: avenin, the oat's own storage protein. Research shows meaningful genetic differences among oat varieties, opening possibilities for future breeding—but genetics alone cannot prevent contamination from wheat, barley, or rye. That still requires clean seed, documented field history, dedicated equipment and milling, testing, and a carefully managed Purity Protocol.
Trust the Genome opens Season 3 with a central idea: genetics can help build a better oat, but protecting the integrity of the final product still depends on the entire system from seed to shelf.

Does “gluten-free” mean the same thing everywhere in the world?
In Season 2, Episode 12 of Trust Your Oats, Trust the Neighbor, Dale Tenhulzen explores how gluten-free labeling laws change across national borders—and why the same bag of oats may be legally labeled gluten-free in one country but prohibited from carrying that claim in another.
The episode begins with Codex Alimentarius, the international reference standard that established the widely used threshold of 20 parts per million while allowing individual countries to decide how oats should be treated. Dale then compares the approaches used in the United States, Europe, Canada, Australia, and New Zealand.
Listeners learn why the United States permits uncontaminated oats in gluten-free foods, why Europe regulates both gluten levels and production methods, and why Canada requires oats to be specifically identified as “gluten-free oats.” The episode also examines the much stricter rules in Australia and New Zealand, where products containing oats cannot carry a gluten-free claim regardless of laboratory results.
The discussion also addresses avenin, the oat protein at the center of the regulatory disagreement, and explains why different authorities have interpreted the same scientific evidence in different ways.
Trust the Neighbor demonstrates that labeling standards may change at the border, but responsible sourcing, documented purity, and transparent production should remain consistent everywhere.

Why does the crop planted last year matter so much to the safety, health, and sustainability of this year’s oats?
In Season 2, Episode 11 of Trust Your Oats, Trust the Rotation, Dale Tenhulzen explores how crop rotation supports soil health while also serving as one of the first safeguards in the Purity Protocol gluten-free system. Before oats are planted, farmers must understand what grew in the field during previous seasons and whether dormant wheat, barley, or rye could create a contamination risk.
The episode examines long-term agricultural research showing how diverse crop rotations can sharply reduce fertilizer and herbicide use while maintaining or improving yields. Listeners learn why oats are especially valuable within a rotation, including their ability to interrupt pest and disease cycles, compete with weeds, capture excess nutrients, and create opportunities for cover crops.
Dale also introduces industrial hemp as a potential non-gluten rotation partner for oat farmers. The discussion considers hemp’s ability to compete with weeds and diversify a cropping system while carefully distinguishing promising early findings from claims that have not yet been fully supported by long-term research.
Trust the Rotation shows how thoughtful farming decisions made years in advance can protect the soil, reduce chemical dependence, and preserve the clean field history required for trustworthy gluten-free oats.
