Consuming peanuts, even in small quantities, especially reduce mortality resulting from cardiovascular disease, according to research published Monday extent consistent with results of previous work.

Eat this peanut has been linked to a decrease in overall mortality by 17 to 21%, depending on the amount consumed, and a decrease from 23 to 38% for deaths from cardiovascular disease, say the researchers whose study appears in the Journal of the American Medical Association, Internal Medicine.

This research was conducted among more than 70,000 Americans, black and white, as well as 130,000 Chinese in Shanghai. Most participants were from lower socio-economic groups.

“In our study, we found that the consumption of peanuts coincided with a decrease in overall mortality especially resulting from cardiovascular disease in American black and white populations, as well as among the Chinese of both genders in Shanghai,” says Hung Luu, an epidemiologist at the medical faculty of Vanderbilt University, the lead author.

Since peanuts are significantly less expensive and more widely available than nuts, encourage increased consumption of peanuts this could be an economical way to improve public cardiovascular health, he said.

“These data comes from epidemiological studies, no controlled clinical trials. Therefore, we can not be certain that the consumption of peanuts as such led to a reduction in mortality,” said Dr. William Blot, Central of cancer research from Vanderbilt University (VICC), co-author of the study.

But, he adds, “The results support previous research suggesting that the health benefits of eating peanuts are rather encouraging.”

Previous research has focused on high-income white populations, the authors note.

Benefits to health peanuts were observed in both sexes and all ethnic groups, the researchers said. They followed the participants for up to 5 years to over 12 years.

The interest of this study is mainly to show that eating small amounts of peanuts, as a pack of 30 grams per week, for example, has protective effects on cardiovascular level.

The peanut is rich in nutrients and contains unsaturated fatty acids, fiber, vitamins and antioxidants, all good for cardiovascular health.

For Professor Peter Weissberg, medical director of the “British Heart Foundation,” which was not involved in the study, “the results of this research suggest that adding a small amount of peanuts to a diet well balanced would be good. ”
