A new study using data from the National Health and Nutrition Examination Survey (NHANES) has found that higher dietary intake of B vitamins—particularly niacin, folate, and choline—is associated with a lower risk of chronic constipation in adults. Researchers analyzed data from over 13,800 individuals aged 20 and above, adjusting for various lifestyle and demographic factors. Those in the highest intake groups for these vitamins showed significantly reduced odds of constipation, with folate intake linked to a 39% lower risk.
Interestingly, the protective effect of B vitamins was more pronounced in individuals who consumed alcohol, suggesting that alcohol may modify how these nutrients influence gut health. While the study does not prove causation, it highlights the potential of dietary changes as a non-invasive strategy for improving digestive health. Incorporating B-vitamin-rich foods like leafy greens, legumes, eggs, and lean meats may be a simple and effective approach to managing constipation.
