Over four years, 44 percent of 215 newly diagnosed overweight diabetes patients on a Mediterranean diet needed glucose-lowering drugs, against 70 percent on a low-fat diet. The Mediterranean group also lost more weight and improved more on glycemic and coronary risk measures.

Lifestyle
Smoking raises type 2 diabetes risk even after quitting
Johns Hopkins researchers followed 10,892 adults for up to 17 years and found people who quit smoking faced a 70 percent higher risk of type 2 diabetes in the first six years, still 30 percent higher at the study's end. They suspect weight gain after quitting.

Older Mexican Americans at higher risk of diabetes
Type 2 diabetes rates among Mexican Americans aged 75 and older doubled since 1993, Diabetes Care reports. Obesity rose from 20 to 29 percent and high blood pressure from 37 to 57 percent, while kidney and vision complications held steady and diabetics faced greater disability risk.
Drug
New diabetes drug waiting for FDA approval
Biodel asked the FDA to approve VIAject, an insulin it says the blood absorbs faster than existing analogs. A trial of more than 884 patients in the US, Germany and India reported faster glucose reductions, lower hyperglycemia and hypoglycemia risk and less weight gain.
Disease
Diabetes genes linked to lipid metabolism
Helmholtz Zentrum Munchen researchers measured 163 metabolic products in blood from 1,800 KORA participants and identified variants in nine genes tied to disturbances in lipid metabolism, including MTNR1B and GCKR, already linked to diabetes. They may serve as early biomarkers.
Food
Coffee consumption linked to lower diabetes risk
A review in Diabetology and Metabolic Syndrome found 14 of 18 cohort studies reported substantially lower type 2 diabetes risk among frequent coffee drinkers, and an Australian meta-analysis put three to four cups a day at 25 percent lower risk. The reviewers say it is too early to advise coffee.
Food
Coffee, tea may reduce diabetes risk
A meta-analysis of about three dozen studies covering 457,000 people found an inverse association between coffee drinking and type 2 diabetes, with risk falling for each additional daily cup. The article cautions these are associations and coffee drinkers may differ in other ways.
Diabetes
Coffee and tea reduce diabetes risk
Pooling 18 studies of 457,922 people, researchers found those drinking three to four cups of coffee a day had about a 25 percent lower risk of type 2 diabetes, with each extra cup linked to a 7 percent reduction. Heavy tea drinkers had about a fifth lower risk.
Diabetes
n-3 polyunsaturated fatty acids help diabetes
A case-control study of 186 type 2 diabetes patients and 180 healthy people in China found higher plasma omega-3 fatty acids tracked with lower insulin resistance. A separate meta-analysis linked coffee and tea to lower diabetes risk, though neither set of studies was a trial.
Disease
Diabetes Epidemic Expected to Double
Researchers project US diabetes cases will nearly double from 23.7 million to 44.1 million by 2034, with annual treatment costs almost tripling from $113 billion to $336 billion. The estimates assume obesity levels plateau and then decline.
Diabetes
Coffee, tea may help prevent diabetes
Pooling 18 studies of 458,000 people, Rachel Huxley's team found each extra daily cup of coffee linked to 7% lower diabetes risk, with similar reductions for decaffeinated coffee and tea. The studies were observational and do not show that coffee prevents diabetes.

Dire Diabetes Predictions Challenge Medicare Debates in Congress
A University of Chicago study projects US diabetes cases rising from 23.7 million to 44.1 million by 2034, with spending climbing from $113 billion to $336 billion even if obesity rates hold flat. Federal diabetes spending could go from $45 billion to $171 billion.
Disease
Diabetes cases to double and costs to triple by 2034
University of Chicago researchers project 44.1 million Americans will have diabetes within 25 years and that spending on the disease will triple to $336 billion by 2034, with Medicare's share climbing from $45 billion to $171 billion.

Vitamin D deficiency may raise risk of type 1 diabetes
Borkar and colleagues in India measured vitamin D in 50 children within a week of a type 1 diabetes diagnosis and 50 others: averages were 20.02 against 26.16 ng/mL, with 58% of the diabetic children deficient against 32%. They call for supplementation trials.
Diabetes
Vitamin D deficiency may boost type 1 diabetes risk
A case-control study in Pediatric Diabetes compared 50 Indian children newly diagnosed with type 1 diabetes to 50 without: average vitamin D was 20 ng/mL against 26, and deficiency appeared in 58 percent versus 32 percent. A Qatari study found a smaller but significant gap.
Diabetes
Drinking coffee may reduce risk of type 2 diabetes
Reviewing 18 cohort studies, Brazilian researchers found 14 showed substantially lower type 2 diabetes risk with frequent coffee drinking, with up to four cups a day linked to reduced risk and higher intake to a greater reduction. They call for more population surveys.
Disease
Fat Producing Hormone May Lower Risk of Type 2 Diabetes
Rob van Dam and colleagues at the Harvard School of Public Health reviewed studies covering at least 14,000 patients and confirmed that high levels of adiponectin, a hormone secreted by fat cells, are linked to lower risk of type 2 diabetes. They are not sure why.

Where can I learn about diabetes?
A reference page explaining that diabetes raises blood glucose because the pancreas makes too little insulin or cells use it poorly, and pointing readers to the National Diabetes Information Clearinghouse, the National Diabetes Education Program and FDA material on glucose meters.
