business news in context, analysis with attitude

HealthDay News reports that new research from Johns Hopkins University School of Medicine and its Heart and Vascular Institute suggests that a low-carbohydrate, high-fat diet, “with regular exercise as part of the plan, don't appear to harm the arteries, as some experts have feared.

"It's pretty clear low-carb is effective for weight loss," study author Kerry J. Stewart tells the news service. "The concern has been that because you are eating more fat this is going to put stress on your blood vessels."

However, HealthDay News notes that Connie Diekman, director of university nutrition at Washington University in St. Louis and past president of the American Dietetic Association, is skeptical. “I would like to see more studies in healthy and unhealthy subjects and longer-duration studies before concluding that this high-fat intake does not impact blood vessel health," she says.
