Glycemic index values are variable, report researchers
In work investigating the reproducibility of glycemic index values, researchers at the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University (USDA HNRCA) have reported that multiple glycemic index value determinations (measure of the rate of glucose absorption into the bloodstream) using a simple test food, white bread,... view more...

Low-glycemic index diet promotes weight loss, cardiovascular risk reduction
A diet high in carbohydrates but low on the glycemic index, which measures the impact of carbohydrates on blood sugar levels, may help promote weight loss, decrease body fat and reduce cardiovascular disease risk. view more (2006-07-25)
Loss of central vision with age may be linked to quality of dietary carbohydrates
Age-related macular degeneration (AMD) is one of the leading causes of vision loss in older adults and a person's risk may partly depend upon diet. view more (2006-06-07)
High-glycemic index carbohydrates associated with risk for developing type 2 diabetes in women
Eating foods high on the glycemic index, which measures the effect of carbohydrates on blood glucose levels, may be associated with the risk for developing type 2 diabetes in Chinese women and in African-American women. view more (2007-11-27)
Link between carbohydrate quality and vision loss is strengthened by new data
Age-related macular degeneration (AMD) and its associated vision loss may be connected to the quality of carbohydrates an individual consumes. view more (2007-07-12)
Limiting refined carbohydrates may stall AMD progression
Eating fewer refined carbohydrates may slow the progression of age-related macular degeneration (AMD), according to a new study from researchers at the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University. view more (2007-10-08)
Low-carb diets prove better at controlling type 2 diabetes
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. view more (2009-01-06)
'Bad Carbs' Not the Enemy, U.Va. Professor Says
The latest common wisdom on carbohydrates claims that eating so-called "bad" carbohydrates will make you fat, but University of Virginia professor Glenn Gaesser says, "that's just nonsense." Eating sandwiches with white bread, or an occasional doughnut, isn't going to kill you, or necessarily even lead to obesity, he said. view more (2007-10-01)
Association between depression severity and poor glycemic control among Hispanics with diabetes
In a study of more than 200 Hispanics with diabetes, researchers at Columbia University's Mailman School of Public Health and College of Physicians and Surgeons found a significant association between depression severity and poor glycemic control (PGC). The findings also confirm that less than one-half of the diabetes patients with moderate or... view more... (2005-05-26)
Blood sugar control before surgery associated with fewer infections afterward
Patients with diabetes who have good control of blood glucose levels before having surgery may be less likely to have infections after their procedures. view more (2006-04-18)
Researchers find glycemic index effective in composite meals
Researchers in the University of Toronto's Department of Nutritional Sciences have some reassurance for diabetics and carb-counters. The glycemic index (GI), the table that lists the quality of carbohydrates in more than 750 common foods, works just as predictably whether subjects consume a single portion of one item, or a normal meal. view more (2006-06-26)
Too much fructose could leave dieters sugar shocked
Here's one tip for how to eat at the holidays: Don't take your cues from Santa. The sugary cookies and fat-laden fruitcakes the mythical North Pole resident eats are a no-no. But you don't have to go no-carb to stay fit at the holidays, either, University of Florida researchers say. view more (2007-12-13)
Review identifies dietary factors associated with heart disease risk
A review of previously published studies suggests that vegetable and nut intake and a Mediterranean dietary pattern appear to be associated with a lower risk for heart disease. view more (2009-04-14)
Study examines calorie restriction and glycemic load
The first phase of a caloric restriction study in human subjects at the Jean Mayer US Department of Agriculture Human Nutrition Research Center on Aging (USDA HNRCA) at Tufts University found evidence suggesting that calorie-restricted diets differing substantially in glycemic load can result in comparable long-term weight loss. view more (2007-04-09)
Breast Feeding May Not Protect Against Obesity
Breast feeding does not protect against overweight and obesity, according to two studies in this week's BMJ. The first study followed 2,250 male Brazilians for 18 years, for whom detailed breast feeding information was collected in early childhood. The results were mostly negative. Duration of breast feeding showed no association with several... view more... (2003-10-15)
Centrefold models are becoming more androgynous
The shapely body characteristics of centrefold models have given way to more androgynous ones, concludes a study in this week's Christmas issue of the BMJ. Researchers looked at trends in Playboy centrefold models' body measurements by analysing 577 consecutive monthly issues of Playboy, from the magazine's inception in December 1953 to December... view more...

Elevated inflammatory marker may be linked to increased risk of age-related eye disease
High blood levels of C-reactive protein, a substance linked to inflammation, appear to be associated with an increased risk for age-related macular degeneration. view more (2007-10-09)
Concern over expanding waistlines of British youth
Waist circumference in young people has risen more steeply over the past 10-20 years than body mass index, particularly in girls. This is a cause for concern because a large waist circumference is linked to a greater risk of disorders such as diabetes and high cholesterol, finds a study in this week’s BMJ. view more (2003-03-19)
New tool can help predict risk of Alzheimer's in elderly
A new tool can help predict whether people age 65 and older have a high risk of developing Alzheimer's disease. Research on the tool is published in the May 13, 2009, online issue of Neurology®, the medical journal of the American Academy of Neurology. view more (2009-05-14)
