‘Low-carb’ best diets for type 2 diabetes
Days when schoolchildren walked to neighbourhood schools are long gone. A new study by a team of researchers led by Paul Lewis, a professor of Urban Planning at the Université de Montréal, shows that only 30 percent of children attending elementary school reach school on foot or by bicycle. The study was conducted from 2006

In a six-month comparison of low-carb diets, one that encourages eating carbohydrates with the lowest-possible rating on the glycemic index leads to greater improvement in blood sugar control, according to Duke University Medical Center researchers.
Patients who followed the no-glycemic diet experienced more frequent reductions, and in some cases elimination, of their need for medication to control type 2 diabetes, according to lead author Eric Westman, MD, director of Duke’s Lifestyle Medicine Program. The findings are published online in Nutrition and Metabolism .
“Low glycemic diets are good, but our work shows a no-glycemic diet is even better at improving blood sugar control,” he says. “We found you can get a three-fold improvement in type 2 diabetes as evidenced by a standard test of the amount of sugar in the blood. That’s an important distinction because as a physician who is faced with the choice of drugs or diet, I want a strong diet that’s shown to improve type 2 diabetes and minimize medication use.”
Eight-four volunteers with obesity and type 2 diabetes were randomized to either a low-carbohydrate ketogenic diet (less than 20 grams of carbs/day) or a low-glycemic, reduced calorie diet (500 calories/day). Both groups attended group meetings, had nutritional supplementation and an exercise regimen.
After 24 weeks, their glycemic control was determined by a blood test that measured hemoglobin A1C, a standard test used to determine blood sugar control in patients with diabetes. Of those who completed the study, the volunteers in the low-carbohydrate diet group had greater improvements in hemoglobin A1C. Diabetes medications were reduced or eliminated in 95 percent of the low-carbohydrate volunteers, compared to 62 percent in the low-glycemic group. The low-carbohydrate diet also resulted in a greater reduction in weight.
“It’s simple,” says Westman. “If you cut out the carbohydrates, your blood sugar goes down, and you lose weight which lowers your blood sugar even further. It’s a one-two punch.”
The diet is not easy for everybody. “This is a therapeutic diet for people who are sick,” says Westman. “These lifestyle approaches all have an intensive behavioral component. In our program, people come in every two weeks to get reinforcements and reminders. We’ve treated hundreds of patients this way now at Duke and what we see clinically and in our research shows that it works.”
Persons with type 2 diabetes who had a diet high in low-glycemic foods such as nuts, beans and lentils had greater improvement in glycemic control and risk factors for coronary heart disease than persons on a diet with an emphasis on high-cereal fiber, according to a study in the December 17 issue of JAMA, the

A study published by the Journal of the American Medical Association (JAMA ) on 16 December 2008 has found that those with type 2 diabetes who had a diet high in low-glycemic foods such as nuts, beans and lentils had greater improvement in glycemic control and risk factors for coronary heart disease than those on

Patients with type 2 diabetes who have poor glycemic control and a certain genetic variation have an increased risk of coronary artery disease, according to a study in the November 26 issue of JAMA, the Journal of the American Medical Association. Among the known risk factors for cardiovascular disease, diabetes mellitus ranks as one of

A new study from the psychology department at Tufts University shows that when dieters eliminate carbohydrates from their meals, they performed more poorly on memory-based tasks than when they reduce calories, but maintain carbohydrates. When carbohydrates were reintroduced, cognition skills returned to normal. “This study demonstrates that the food you eat can have an immediate
