A meta-analysis of data from 15 studies published prior to Aug 2010 suggests eating lots of vegetables, which are high in folic acid or folate may help prevent coronary heart disease (CHD) or coronary artery disease.
The study led by Z-M. Wang and colleagues at Nanjing University of Technology in Nanjing, China found intake of folate, which is found high in vegetables, was inversely associated with risk of coronary heart disease.
Wang and colleagues found the association after analysing data from 7 studies on dietary folate intake and 8 others on blood folate levels.
Data on dietary folate intake showed those who had the highest intake of folic acid were 31 percent less like to experience coronary heart disease than those who had the lowest intake. An increase of 200 ug per day in the intake of folate was correlated with a 12 percent reduction in the risk of CHD.
Data on the serum folate showed that those who had the highest levels were 26 percent less likely to suffer coronary heart disease.
