Higher dietary fiber intake is associated with a 25% reduction in all-cause mortality in adults with established cardiovascular disease.
If you have heart disease, eating more fiber-rich foods like whole grains, fruits, and vegetables can help you live longer. Studies show that people with heart disease who eat more fiber have a 25% lower risk of dying from any cause compared to those who eat less fiber.
GoodSupportsMEDIUM confidence
A 25% reduction in all-cause mortality was observed for those consuming the most fibre when compared with those consuming the least.
Why this rating
Evidence is 'Moderate' certainty based on prospective cohort studies, which are observational but controlled for medication use.
