LowGlycemic-Load Diet Lowers CV Risk
A diet with a low glycemic loada measure of how readily foods are
digestedappears to be more effective than conventional low-calorie,
low-fat diets in reducing the risk of cardiovascular disease, according to a
recent report.
Researchers conducted a randomized, controlled study to compare an ad
libitum lowglycemic-load diet, with 4550% of calories from
carbohydrates and 3035% of calories from fat, with a conventional
calorie-restricted diet that derived 5560% of calories from
carbohydrates and <30% from fat.
Over a 6-month period, body weight decreased in people on both diets. But
those on the lowglycemic-load diet had significantly lower
triglycerides and plasminogen activator inhibitor-1 (PAI-1). No difference
between the two diets was noted in levels of cholesterol, blood pressure, or
insulin sensitivity.
"An ad libitum lowglycemic-load diet may be more efficacious
than a conventional, energy-restricted, low-fat diet in reducing
cardiovascular disease risk," researchers conclude.
