FRIDAY, Aug. 20 — For people with the metabolic syndrome — a cluster of risk factors such as obesity, high blood pressure, high levels of blood fats or triglycerides and high blood sugar — adding a little fish oil to a diet low in saturated fats and high in complex carbohydrates might be just the ticket, a new study suggests.
"When you add omega-3 to a high carbohydrate, low-fat diet, you can prevent the long-term adverse effect that a high-carbohydrate diet induces on [blood fats]," said study author Dr. Jose Lopez-Miranda, a professor of medicine at the Reina Sofia University Hospital and the University of Cordoba, Spain.
The study is published in the September issue of the Journal of Nutrition.
Lopez-Miranda and his team looked at 117 people with metabolic syndrome, which raises the risk of heart disease and stroke. They assigned them to one of four diets for 12 weeks. The diets were: high fat/rich in saturated fats; high fat/rich in monounsaturated fats (such as fish and olive oil), low fat and high in complex carbohydrates (such as whole grains, fruits, vegetables), low fat and high in complex carbs but with the fish oil supplement included.
