The report, published in the American Journal of Clinical Nutrition, comes out of a large ongoing study called the Framingham Heart Study. Dietary information and abdominal fat measurements from 2,834 participants in the larger study were included in this report.
For the dietary analysis, grains were put into two categories:
Measurements of the visceral fat were lower in whole grain eaters and higher in refined grain eaters:
Before you start thinking that you need only add some whole grain servings to your day in order to reap their benefit, consider the following: the study also found that people who ate lots of both whole and refined grains did not see similar improvements in visceral fat measurements as people who ate lots of whole—but not refined—grains.
“These findings suggest that if individuals are already eating several daily servings of refined grains, the inclusion of whole grains in the diet may not translate into lower amounts of visceral fat,” said lead study author Dr. Nicola McKeown of Tufts University in Boston. “Instead, efforts should be made to replace refined grains in the diet with whole grains.”
Here are some ways to replace refined grains with whole grains:
While you’re at it, don’t forget about the other components of a heart-healthy diet: fruits, vegetables, nuts and seeds, legumes, and occasionally fish.
