Study Shows How a High-Fructose Diet Sabotages Learning, Memory
Attention kids, binging on soda and sweets for as little as six weeks may make you stupid, according to a new UCLA study on sugar, learning and memory.
A new UCLA rat study funded by the National Institute of Neurological Disorders and Stroke is the first to show how a diet steadily high in fructose slows the brain, hampering memory and learning — and how omega-3 fatty acids can counteract the disruption. The study was published in peer-reviewed Journal of Physiology in its May 15, 2012 edition.
While the price of springtime fruits and vegetables seems to increase each year, stocking up on specific cancer-fighting foods still makes economical sense,according to the cancer experts from The University of Texas MD Anderson Cancer Center.
Study Looks at Whether Low-Carb Diets Really Damage Kidneys?
Low-carbohydrate, high-protein diets, like the Atkins diet, have been very popular among carb-hating dieters for years. For just as long, nutrition experts have worried that low-carbohydrate, high-protein diets might be harmful to the kidneys.
A new study on the effects of Low-carbohydrate, high-protein diets on the kidneys appears in an July 2012 issue of the Clinical Journal of the American Society of Nephrology (CJASN) looks into these safety concerns.
Does Low-carbohydrate High-protein Diets Impact the Kidneys?
Indiana University School of Medicine researchers compared the effects of a low-carbohydrate, high-protein diet versus a standard low-fat diet on a variety of kidney-related measures in 307 obese individuals without kidney disease over a two year period.
The researchers found that a low-carbohydrate high-protein weight loss diet did not cause noticeably harmful effects to patients’ kidney function or their fluid and electrolyte balance compared with a low-fat diet.
“These results are relevant to the millions of healthy obese adults who use dieting as a weight loss strategy,” said Dr. Friedman.
The authors noted that further follow-up is needed to determine even longer-term effects of the low-carb diet on the kidneys. Additional studies should also evaluate the effects of the the low-carb diein different types of individuals, such as those with chronic kidney disease, diabetes, or hypertension, and those at increased risk of developing kidney stones.
An editorial will accompany the July 2012 print publication of this health study.
