Summary
- Your genetics influence which fungi grow in your gut, and these fungi directly affect your risk for chronic conditions like heart disease
- Researchers discovered 148 genetic variants linked to nine groups of gut fungi, proving that your DNA helps shape your gut health
- Antibiotics kill bacteria but leave fungi untouched, allowing harmful fungal strains to overgrow and increase disease risk
- Two people eating the same foods can have very different health outcomes because genetic differences decide which fungi thrive in their gut
- Gut microbiome patterns, including fungi and bacteria, are strong predictors of cardiovascular disease risk, yet most clinics still ignore this critical factor

| 0:23.6 | Hello, and welcome to Dr. Mercola's cellular wisdom. I'm Ethan Foster. Today we're |
| 0:29.5 | examining new research on your gut microbiome, the fungal side of your microbiome, and how |
| 0:35.2 | genetics, antibiotics, and microbial patterns converge to predict chronic |
| 0:40.0 | disease risk, including cardiovascular disease. I'll guide the key findings and what they could mean |
| 0:45.9 | for you. I'm Alariskai. We'll keep this focused and practical. You'll hear how scientists connected |
| 0:52.3 | 148 genetic variants to specific gut fungi, why a yeast called Kazakhstania tracks with heart risk and how antibiotic use can tilt your microbial balance toward trouble, will close with concrete steps drawn directly from the recommendations provided. |
| 1:08.1 | A team at Penn State's One Health Microbiome Center ran a genome-wide association study, |
| 1:13.6 | scanning human DNA alongside stool and blood measures from 125 individuals. |
| 1:19.6 | They linked 148 genetic variants across seven chromosomes to nine groups of gut fungi. |
| 1:26.6 | One genus, Kazakhstania, stood out for its association |
| 1:30.3 | with cardiovascular disease risk, and the genetic fungal signals were validated in larger |
| 1:35.7 | cohorts, including U.K. and international coronary artery disease data sets. |
| 1:41.3 | The authors were clear about why this matters. |
| 1:44.2 | Gut fungi have been understudied compared to bacteria, yet the data show your genes |
| 1:48.9 | shape which fungi can take hold. |
