Study: Good carbs, more protein could help heart

first_imgCHICAGO – Deciding what to have for a healthy breakfast just got a little easier. While a healthy high-carb diet has been shown to be good for you, replacing a few of the carbohydrates with a little protein like scrambled egg substitute or beneficial fats like olive oil margarine could be even better, helping further reduce heart disease risks, a study found. At dinner, this might mean instead of pasta, trying black bean tacos and multigrain pilaf with olive oil, the researchers said. They had volunteers try three variations of the same diet, all of them low in saturated fats and including plenty of fruits and vegetables.

The study also appears in today’s Journal of the American Medical Association. All participants tried each of the diets, eating meals prepared in a research kitchen and taking a few weeks’ break before starting the next diet. The volunteers’ average blood pressure started out borderline high – 131 over 77. Systolic pressure – the top number in blood pressure readings – fell by an average of about 8 points while they were on the carb diet, 9.5 points on the protein diet and 9.3 points on the healthy fats diet. Levels of LDL cholesterol, the bad kind, measured 129 on average at the start; 100 is considered optimal. LDL levels fell an average of almost 12 points on the carb diet, about 14 points on the protein diet, and about 13 points on the healthy fats diet. Those reductions likely would translate into less heart disease if the diets were widely adopted, the researchers said. They estimated that for every 100 people with mild high blood pressure, there would be one less heart attack over 10 years for those on the protein or healthy fats diet, compared with the more carb-friendly diet. Appel said the high-protein diet also seemed to produce feelings of fullness and reduced appetite. “These symptoms raise the intriguing possibility that if individuals were to follow these diets long term, there may be some weight loss on the protein diet,” he told conference participants. Dr. Timothy Gardner, a Delaware cardiologist, said at the meeting that the study was “a tricky, difficult type of study to conduct, controlling all the factors, with very interesting results.” A JAMA editorial about Appel’s research, which was funded by the National Institutes of Health, questioned whether people in the real world would stick to the diets since they’d have to buy and prepare their own meals. “Longer trials examining actual cardiovascular event outcomes will be needed to convince a skeptical public of the benefit of yet another unique and difficult-to-achieve dietary regimen,” said editorial author Dr. Myron Weinberger of Indiana University. Rachel Johnson, a University of Vermont nutrition professor, said the results refine “what we already know. It’s not a huge about-face.” 160Want local news?Sign up for the Localist and stay informed Something went wrong. Please try again.subscribeCongratulations! You’re all set!last_img
