High Dietary Fiber Intake Is Associated with Lower Mortality After Myocardial Infarction

High dietary fiber intake is associated inversely with cardiovascular (CV) risk factors, but whether it lowers mortality after myocardial infarction (MI) risk is unclear. Using data from the Nurses' Health Study and Health Professionals Follow-Up Study, researchers examined associations between post-MI dietary fiber intake and mortality. Analysis involved 2300 women and 1800 men who had no known CV disease, stroke, or cancer at baseline; survived a first MI during follow-up; and completed pre- and post-MI food frequency questionnaires. Median follow-up was about 9 years.

Compared with participants in the lowest quintile of post-MI fiber intake, those in the highest quintile had significantly lower risk for all-cause death (adjusted hazard ra…
