Healthy Diets Linked too Lower Constipation Risk in new Study
Boston,MA – A large-scale study of over 96,000 middle-aged and older adults has found a significant link between dietary patterns and the incidence of constipation. Researchers discovered that individuals adhering to Mediterranean or plant-based diets were less likely to experience the common digestive issue. The findings, published with DOI 10.1053/j.gastro.2025.06.020,suggest dietary interventions could play a role in preventing chronic constipation.
The research, conducted by a team at Massachusetts General Hospital, indicates the benefits extend beyond previously understood cardiovascular advantages of these diets. “Our results suggest that, beyond their known cardiovascular health benefits, certain healthy diets may also have beneficial effects on the gut as we age,” explained Dr. Kyle Staller, from the Department of Gastroenterology.
Notably, the study revealed the positive effects weren’t solely attributable to fiber intake. “We have always assumed that the benefits of a healthy diet are primarily based on fiber. but the positive effect on constipation of these healthy diets was autonomous of fiber intake,” Staller stated.
The research suggests a diet abundant in vegetables, nuts, and healthy fats may be particularly effective in preventing chronic constipation in middle-aged and older adults. conversely, a western diet was associated with an increased risk of the condition. this is the first study to demonstrate that specific dietary patterns can proactively prevent the development of chronic constipation.
