(HealthDay News) –Any one of three heart-healthy diets — low-fat, low-carbohydrate, Mediterranean — can reverse the thickening of artery walls that can lead to heart attack and stroke, an Israeli study indicates.
“Once one adheres to a sensible diet, even though you experience only a moderate weight loss, if you stick to it long enough you can cause regression of atherosclerosis,” explained Iris Shai, a nutritional epidemiologist at Ben-Gurion University of the Negev, and lead author of a report to be published in the March 16 print issue of the journal Circulation.
Atherosclerosis involves a thickening and narrowing of blood vessels. When narrowing leads to a full blockage of blood flow, heart attacks or strokes are the result.
Shai and her colleagues assigned 140 middle-aged, overweight men and women to one of three low-calorie diets: low-fat; low-carbohydrate; or the Mediterranean diet, which emphasizes fruits, vegetables and healthy fats such as those found in olive oil.
About one-third of the participants were taking blood pressure medications and one-quarter were taking cholesterol-lowering medications, mostly statins.
