Your mom was right—eat all the colors, and a lot of them

Research shows Mom was right. Eat all the colors. This is a meta-analysis. Fruit and Vegetable Intake and Mortality: Results From 2 Prospective Cohort Studies of US Men and Women and a Meta-Analysis of 26 Cohort Studies (ahajournals.org)  Free, original research article. Print it and read between the food commercials on TV.

• A higher intake of fruit and vegetables was associated with lower total and cause-specific mortality in a nonlinear manner in both an original data analysis in 2 prospective cohorts of US men and women and a meta-analysis of 26 prospective cohort studies.
• The lowest risk of mortality was observed for ≈5 servings per day of fruit and vegetable intake, but above that level the risk did not decrease further.
• The thresholds of risk reduction in mortality were 2 servings daily for fruit intake and 3 servings daily for vegetable intake

My favorite vegetables, peas, corn and potatoes, are not associated with lower mortality. Too starchy. Darn. It's just hard to eat this much of anything.

Despite recommendations in dietary guidelines for decades to increase fruit and vegetable intake, the current average intake among US adults is 1 serving of fruit and 1.5 servings of vegetables per day. Not good. There have been many campaigns (cited in the article) to change this because poor nutrition contributes to the burden of disease and premature death.

BTW, this is a premiere, peer reviewed journal. When I was a librarian, Circulation and its many numbered series, was the bane of my existence.
