Butyrate is a powerhouse short-chain fatty acid (SCFA) essential for gut integrity, immune balance, metabolism, and even brain health. This pillar page will guide readers through everything they need to know about butyrate — from supplements to foods, to strategies for boosting production naturally. Table of Contents What Is Butyrate? Best Butyrate Supplements Sodium & Calcium Butyrate Tributyrin Supplements Prebiotic + Butyrate Blends Clostridium butyricum Probiotics Best Foods That Increase Butyrate Naturally Resistant Starch Foods Soluble & Fermentable Fiber Polyphenol-Rich Foods Foods That Contain Butyrate Directly How to Maximise Butyrate Production Supplements vs Foods: Which Is Better? Who Benefits Most from Butyrate? Key Takeaways What Is Butyrate? Butyrate (butyric acid) is a short-chain fatty acid produced when beneficial gut bacteria ferment fiber and resistant starch. According to research on PubMed, butyrate is the primary energy source for colonocytes, the cells ...

Updated Review • Critical Appraisal of RCTs, Observational Confounding, & Saturated vs. Polyunsaturated Fat 💡 Executive Summary & Key Takeaways Surrogate Endpoints vs. Hard Outcomes: Seed oils (rich in linoleic acid) lower LDL cholesterol compared to butter. However, lowering LDL via dietary substitution has not reliably translated into reductions in total mortality or cardiovascular events in randomized trials. Re-analyzed RCT Data: Historically buried data from the Minnesota Coronary Experiment and the Sydney Vegetable Oil Heart Study showed that replacing saturated fats with seed oils lowered cholesterol, but failed to reduce heart disease deaths—and in some subgroups, mortality actually increased. Observational Confounding: Large observational studies favoring seed oils suffer heavily from "healthy user bias," where seed oil consumers also exercise more, smoke less, and eat higher quality diets overa...

OneDayMD Editorial Team · Reviewed & updated August 2026 · ~18 min read Quick Answer Ray Peat (1936–2022) was an American biologist whose "bioenergetic" or "pro-metabolic" theory framed nearly every health outcome — mood, fertility, sleep, immunity, aging — as downstream of how efficiently the body's cells convert fuel and oxygen into usable energy. His framework centers on thyroid function, progesterone, dietary sugar and glycogen, and avoidance of polyunsaturated fats (PUFAs), while treating adrenaline and cortisol as a costly emergency backup system rather than a healthy baseline. Parts of the framework overlap with established physiology; central claims — high sugar intake as broadly protective, routine aspirin use, and blanket PUFA avoidance — lack clinical trial support and in several places run counter to current mainstream nutrition and cardiology guidance. It's best treated as an interesting theoretical lens, not a substitute for indi...

A comprehensive analysis merging clinical trials on high-dose fermented soy enzyme therapy, statin head-to-head comparisons, and plaque regression mechanisms. Atherosclerosis remains the leading cause of cardiovascular events worldwide. While statins focus primarily on lowering low-density lipoprotein (LDL) cholesterol, groundbreaking clinical research reveals that nattokinase —a fibrinolytic enzyme derived from traditional Japanese nattō —acts directly on the structural matrix of established arterial plaque. Credit: Oasis Medical Institute 1. The Head-to-Head Clinical Trial (Ren et al., 2017) In a 26-week randomized controlled study, 82 patients with carotid atherosclerosis received either Nattokinase (6,000 FU/day) or Simvastatin (20 mg/day). Key outcomes included: Carotid Plaque Reduction: Nattokinase achieved a 36.6% reduction in plaque area vs. 11.5% in the statin group. HDL Elevation: Nattokinase significantly increased benefici...
