Early Fruit and Veggie Intake Can Lower Later Cardiovascular Risk


Eating a diet rich in fruits and vegetables as a young adult may help lower coronary artery calcium (CAC), a known predictor of CV events, up to two decades later, suggests new research.


Analysis of a cohort of more than 2000 participants from the Coronary Artery Risk Development in Young Adults  (CARDIA) study showed that, after adjustment for factors such as age, body-mass index (BMI), and smoking status, those who consumed seven to nine daily servings of fruits and vegetables at baseline (when they were a mean age of 25.3 years) were 26% less likely to have CAC 20 years later vs those who consumed only two to four servings of these items per day.


However, when stratified by sex, this association remained significant only in women, with those in the top tertile of fruit and vegetable intake 45% less likely to have CAC vs those in the bottom tertile.


CAC, “a direct marker of coronary atherosclerosis, is . . . a powerful CVD risk stratification tool,” note the investigators, led by Dr Michael D Miedema (Minneapolis Heart Institute, MN). 


“We frequently tell younger people ‘what you eat matters,’ but really we don’t have any good evidence that it has an impact on their risk of heart disease down the road,” he said. “So the point of this study was to look at a younger population to see: is it okay to wait until your 50s to eat healthily? Or does what you do in your 20s and 30s actually matter?”


The findings were published online October 26, 2015 in Circulation.
