Swap oatmeal for buckwheat (kasha)
Thomas positions buckwheat as a superior alternative to oatmeal, not because oatmeal is harmful, but because buckwheat offers a stronger metabolic and digestive advantage. He explains that buckwheat acts like a cereal but isn’t a grain, making it easier on the gut. Its soluble fiber content is especially high, which can modulate appetite and energy levels throughout the morning. Drawing on the cultural example of Russia, where kasha is a daily porridge, he argues that the country’s exceptionally low diabetes rates may be partly attributable to this staple food. The preparation is nearly identical to oatmeal—one cup of groats to one cup of water—so the barrier to entry is minimal. He recommends adding butter and salt, not only for taste but also to align with traditional recipes that provide healthy fats and improve the absorption of fat-soluble vitamins found in buckwheat.
As a pseudo-cereal (not a true grain), buckwheat lacks gluten and certain prolamins that can irritate the gut. Its high soluble fiber slows gastric emptying and reduces post-meal glucose spikes. Thomas notes that Russians, who consume kasha as a staple, have the lowest rates of insulin resistance and diabetes globally, implying a population-level metabolic benefit.
The Russians have the literal lowest rates and instances of insulin resistance and diabetes and the best glucose tolerance of any country on Earth. And this is a staple for them, this porridge.
