Dietary live microbe intake and its association with Parkinson’s disease in American adults: an NHANES analysis (1999–2018)

This study found that eating more foods rich in live microbes—like fermented products (yogurt, kimchi) and fresh fruits and vegetables—is associated with lower rates of Parkinson’s disease in American adults. The protective effect was strongest in people without obesity. The live microbes appear to work by maintaining a healthy gut environment, reducing inflammation, and protecting nerve cells from damage. This suggests that regular consumption of microbe-rich foods from nature might be a simple, inexpensive way to help prevent or slow Parkinson’s disease.

Sex-Specific Associations Between Prebiotic Supplement Intake and Sarcopenia Risk: Evidence From NHANES

This study examined whether taking prebiotic supplements helps prevent sarcopenia (age-related muscle loss) differently in men versus women using health data from thousands of Americans. Researchers found that women who consumed prebiotics had significantly lower rates of sarcopenia, while this benefit was not observed in men. These findings suggest that prebiotic supplements may be particularly beneficial for women’s muscle health, though more research is needed to understand why this sex difference exists.

Association of mushroom consumption with all-cause and cause-specific mortality among American adults: prospective cohort study findings from NHANES III

This study followed over 15,000 American adults for nearly 20 years and found that people who ate mushrooms had a lower risk of dying from any cause compared to those who didn’t eat mushrooms. The more mushrooms people ate, the greater the benefit. Replacing red or processed meat with mushrooms was associated with even greater longevity benefits. Mushrooms’ beneficial effects likely come from their high antioxidant content, particularly compounds called ergothioneine and glutathione.
