Dr. Joseph Mercola - Take Control of Your Health The Dangerous Relationship Between Salmonella and Yeast in Your Gut
Oct 21, 2025
Salmonella causes over 1.35 million infections in the U.S. yearly, and its severity can escalate when combined with Candida yeast in the gut. Fascinating research shows that Candida can enhance Salmonella's invasion while dampening immune responses. Interestingly, Salmonella may also suppress Candida under certain conditions, highlighting their competitive relationship. Tips include avoiding antibiotics when possible, consuming lysine-rich foods, and improving digestion through lifestyle changes like sunlight exposure and healthy eating. These strategies can help create a gut environment that resists opportunistic infections.

Episode notes
Candida Amplifies Salmonella Invasion
- Candida albicans colonization, present in over 60% of healthy people, can amplify Salmonella invasion and spread to organs.
- The presence of Candida triggered Salmonella's invasion genes and increased accumulation in the large intestine and liver/spleen in models.
SOP-B Triggers Arginine-Mediated Invasion
- A Salmonella protein SOP-B causes Candida to release arginine, which fuels bacterial invasion and suppresses inflammation.
- This dual effect both energizes Salmonella's invasion machinery and dampens host defense signals.
Use Lysine-Rich Foods To Counteract Arginine
- Adding lysine partially countered Candida-driven changes and blunted Salmonella's invasion in the study.
- Emphasize lysine-rich whole foods like eggs, raw dairy, and pasture-raised meats to help rebalance gut chemistry.
