Researchers at the University of Texas Southwestern Medical Center found that exercise helped reverse blood glucose abnormalities in control mice on a high-fat diet, whereas autophagy-deficient mice did not show the same benefits from physical activity. The results in the journal Nature suggest that autophagy, in which a cell degrades damaged or unneeded parts of itself to produce energy in response to hunger, may play a key role in how exercise protects against diabetes, researchers said.
People with type 1 or type 2 diabetes face a threefold increased risk of potentially fatal flu complications compared with those who do not have diabetes, the CDC has said. Cough syrups can contain 50% sugar, and some cold and flu medications contain alcohol, so patients with diabetes should opt for treatments that don't pose risks for their blood glucose levels, says Debra Spector, a registered dietitian and certified nutritionist.
Prediabetes is a red flag for the development of type 2 diabetes and a "huge health problem that is not being addressed to the fullest," said registered dietitian and diabetes educator Hope Warshaw. Health experts want blood glucose monitoring and education to get the same amount of public attention as cholesterol.
A "vending machine" that dispenses health advice rather than snacks has been installed at an elementary school in Salt Lake City. Tamara Sheffield of Intermountain Healthcare, which installed the machine, said it is intended to make students reconsider their snacking choices. The machine doesn't actually take money, and when students press its buttons, it offers advice such as "I'm a vending machine and can't move without someone's help. Keep buying food like this and we'll have that in common."
A study found that people who drank three cups of black tea a day lowered their blood pressure by two to three points, on average. "At a population level, the observed differences in [blood pressure] would be associated with a 10% reduction in the prevalence of hypertension and a 7% to 10% reduction in the risk of [heart disease and stroke],” researchers wrote.
