Moderate Wine Intake May Improve Cholesterol, Blood Sugar Control in Type 2 Diabetes

Researchers assigned over 200 patients with well controlled type 2 diabetes who don’t normally drink alcohol to eat a Mediterranean diet, and drink 5 oz of either red wine, white wine, or mineral water with dinner for 2 years. The red wine group significantly increased good cholesterol (HDL and apolipoprotein A), and the white wine group significantly decreased fasting blood sugar. “Slow alcohol metabolizers” (based on whether they carry the ADH1B*1 allele) benefited from both red and white wine on their blood sugar control. Both wine groups had improved sleep quality compared with the water group. The researchers concluded that a Mediterranean diet with moderate wine intake “is apparently safe and modestly decreases cardiometabolic risk” in patients with type 2 diabetes.

Sleep Apnea Improves with Mediterranean Diet

Researchers at Greece's University of Crete evaluated 900 patients to choose 40 obese adults with moderate to severe apnea. They divided the patients randomly into two groups, with half following the Mediterranean Diet and the other half following a "prudent diet;" everyone was encouraged to walk and exercise 30 minutes daily. After six months, the scientists found that the Mediterranean Diet group showed reduced apnea during REM sleep (about 25% of sleep) and a greater reduction in waist circumference and abdominal fat, as well as greater adherence to the diet.

Sleep Quality Drops with Latino Acculturation

Sleep duration and quality can affect health, so scientists at the Cleveland Clinic set out to compare sleep patterns in 1046 Mexican Americans (620 born in Mexico and the rest in the U.S.) with 5160 non Hispanic Americans. The Mexico-born immigrants had the healthiest sleep patterns, and increased acculturation (measured by English spoken at home rather than Spanish) correlated to an increased risk of poor sleep.
