GI Diet :: 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, resulted in a relatively high level of inter-individual (among different individuals), and intra-individual (within the same individual) variability.

Diabetes :: Breath analysis offers potential for noninvasive blood sugar monitoring in diabetes

Breath-analysis testing may prove to be an effective, noninvasive method for monitoring blood sugar levels in diabetes, according to a University of California, Irvine study.

Diabetes :: Older blacks and Latinos still lag whites in controlling diabetes

Despite decades of advances in diabetes care, African Americans and Latinos are still far less likely than whites to have their blood sugar under control, even with the help of medications, a new nationally representative study finds. That puts them at a much higher risk of blindness, heart attack, kidney failure, foot amputation and other long-term diabetes complications.

Liver :: Quick-burning carbs may cause fatty liver

The obesity epidemic has spawned not just diabetes, but another serious public health problem: a surge in fatty liver disease, which can lead to cirrhosis and liver failure. Now, research suggests that limiting consumption of high-glycemic-index carbohydrates can prevent the condition in mice. A clinical trial is now testing this idea in overweight adolescents, as well as the possibility of reversing fatty liver disease through diet.

Insulin :: Smart insulin nanostructures pass feasibility test, UT study reports

Biomedical engineers at the University of Texas School of Health Information Sciences at Houston have announced pre-clinical test results in the September issue of the International Journal of Nanomedicine demonstrating the feasibility of a smart particle insulin release system that detects spikes in glucose or blood sugar levels and releases insulin to counteract them

Stress :: Ancient mechanism for coping with stresses also gives cancer a boost

An ancient mechanism for coping with environmental stresses, including heat and toxic exposures, also helps cancerous tumors survive, reveals a new report in the Sept. 21, 2007, issue of Cell, a publication of Cell Press. The findings could lead to a new way to treat cancer and may also have implications for the treatment of neurodegenerative and other diseases, according to the researchers.

Diabetes :: ACTOS is associated with a 38 percent lower risk of heart attack

New research, including two studies presented this week at the 43rd Annual Meeting of the European Association for the Study of Diabetes (EASD), further support the cardiovascular safety of ACTOS (pioglitazone HCI) and its benefits regarding improved blood glucose and blood lipid levels for patients with type 2 diabetes.
