How effective is folate in preventing heart attacks?

Dr. Michael Roizen, MD
Internal Medicine
One study estimated that if everyone had proper levels of folate, the number of heart attacks in the United States could be reduced by 40,000 to 150,000 a year. In fact, these numbers may actually be too conservative! Statistics from risk-factor studies predict that a more realistic estimate would be a reduction of one third in the rate of heart attacks and strokes in the United States every year. In other words, perhaps every year as many as 450,000 heart attacks and 170,000 strokes occur because we don't get enough folate.
