Summary
On episode 207 of 40+ Fitness, Coach Allan sits down with Dr. John Douillard, a globally recognized leader in natural health, Ayurveda, and sports medicine, and creator of LifeSpa.com, the leading Ayurvedic health and wellness resource online, to talk about his book Eat Wheat.
John argues that processed foods, not wheat itself, are the real cause of modern digestive damage. He points out humans have eaten gluten-containing grains for millions of years, and that cutting hard-to-digest foods out entirely, as many gluten-free diets do, carries its own risks: more mercury retention, fewer beneficial gut bacteria, and weaker immune response.
From there the conversation turns practical: how liver and bile congestion drive poor digestion, which foods and spices help reboot the body’s own digestive fire, and why eating with the seasons, rather than grazing year-round, matters more than any single food being “good” or “bad.”

Key Takeaways
- Processed foods, not wheat, are the real culprit. When cholesterol was pulled from the American diet in 1960, it was replaced with processed, refined oils meant to extend shelf life, and John says that shift is what actually broke down digestive health.
- Humans have a longer history with gluten than with meat. Gluten has been found in the teeth of ancient humans dating back 3.4 to 4 million years, compared to roughly 500,000 years of hunting meat, meaning we have more genetic adaptation to digesting grains than the modern paleo narrative suggests.
- Going fully gluten-free carries measurable downsides. John cites research showing people on gluten-free diets had four times the mercury in their blood, less beneficial gut bacteria, and fewer killer T cells than people who ate wheat, evidence tied to the hygiene hypothesis (the same reason Amish children have far lower asthma rates than modernized Hutterite children with the same genetics).
- Poorly digested gluten clogs the lymphatic system. When digestion is weak, gluten molecules are too large to enter the bloodstream and instead get pulled into lymphatic ducts, blocking the delivery of fat as energy and leaving the body to store that fat around the belly instead.
- Liver and bile congestion, not the pancreas, is where poor digestion usually starts. Bile buffers stomach acid and helps digest and detoxify fat; when bile flow is blocked by processed fats, the stomach eventually stops producing enough acid, and digestion, detox, and regularity all suffer.
- Specific foods get bile moving again. John’s short list: beets, apples, celery, artichokes, fenugreek tea, and fennel tea.
- Five spices together reboot the body’s own digestive enzymes. Ginger, cumin, coriander, fennel, and cardamom, combined, help the stomach make more of its own acid, the liver make more of its own bile, and the pancreas make more of its own enzymes, reducing reliance on supplements.
- Digestion is seasonal, not constant. The enzyme amylase, which breaks down wheat and grain, rises in the body during fall and winter and drops in spring and summer, mirroring when wheat was historically harvested and eaten.
- Grazing all day trains the body to burn only what you just ate. Eating three real meals without snacking between them, rather than a meal-and-snack cycle, gives the body a reason to burn stored fat as fuel via the lymphatic system between meals.
“Let’s not blame the wheat because the science really doesn’t support that.”
