Summary
- Butyrate is a short-chain fatty acid (SCFA) produced by gut bacteria that ferment dietary fiber. It serves as essential fuel for colon cells and maintaining overall systemic health
- Adequate fiber intake — around 30 grams daily — is crucial for butyrate production. Without it, your body burns stored fat and protein, creating disease-causing byproducts
- Butyrate strengthens your gut barrier, preventing intestinal permeability that allows harmful substances to enter the bloodstream and trigger autoimmune responses
- Research shows butyrate improves insulin sensitivity, reduces diabetes risk, lowers bad cholesterol, prevents colorectal cancer, and supports brain health
- Boost butyrate by eating fiber-rich foods, resistant starches, fermented foods and probiotics, while avoiding processed foods, managing stress, and limiting unnecessary antibiotics

| 0:20.9 | Hello and welcome to Dr. Mercola's cellular wisdom. I'm Ethan Foster and today we're |
| 0:26.5 | exploring Beauty Rate, the short chain fatty acid your gut bacteria make when you feed them fiber, |
| 0:32.6 | and why it matters for your metabolic, immune, and brain health. I'm Alara Sky. |
| 0:42.0 | Beauty rate is created when beneficial microbes ferment dietary fiber, |
| 0:45.0 | and your colon cells use it as a primary fuel. |
| 0:48.6 | When you produce enough, your gut lining stays strong. |
| 0:53.7 | When you don't, permeability rises and poorly digested particles slip through, irritating your immune system, and setting the stage for broader problems. |
| 0:58.0 | Think about your daily fiber target. |
| 1:01.0 | Hitting around 30 grams per day is the practical goal, with boxal noting 28 grams for women and 34 for men. |
| 1:08.0 | If you chronically miss that mark, your body pivots to burning stored fat |
| 1:12.6 | and protein for fuel, generating byproducts that drive disease. Another reason consistent fiber |
| 1:18.4 | matters. There are foods that already contain buterate too. Grass-fed butter and ghee |
| 1:23.8 | provide it directly, and ghee may be more tolerable if you're sensitive to dairy proteins. |
| 1:29.5 | The key is choosing products from grass-fed cows, because that's where the meaningful |
| 1:33.8 | butyrate content comes from. Your gut barrier depends on this fuel. As fiber-eating microbes produce |
| 1:40.5 | short-chain fatty acids, they energize colon cells and support tight junctions. |
| 1:46.0 | With adequate buterate, the mucus layer remains robust. |
