Vit-D cuts diabetes risk in obese kids

Researchers have found that vitamin D supplements can help obese children and adolescents control their blood-sugar levels, which may help them stay clear off the disease.

Being obese puts individuals at greater risk for developing Type 2 diabetes.
“By increasing vitamin D intake alone, we got a response that was nearly as powerful as what we have seen using a prescription drug,” Catherine Peterson, an associate professor of nutrition and exercise physiology at MU, said.

“We saw a decrease in insulin levels, which means better glucose control, despite no changes in body weight, dietary intake or physical activity,” he said.

Peterson and her colleagues studied 35 pre-diabetic obese children and adolescents who were undergoing treatment in the MU Adolescent Diabetic Obesity Program.
All study participants insufficient or deficient vitamin D levels and had similar diets and activity levels.

Depression may diminish benefits of healthy behaviours

Depression may inhibit the anti-inflammatory effects typically associated with physical activity and light-to-moderate alcohol consumption, a new study by researchers at Duke Medicine has suggested.

The finding – based on measurements of the cardio-metabolic risk marker C-reactive protein (CRP) – points to another potential danger of depression.

"Our findings suggest depression not only directly affects an individual's mental and physical health; it might also diminish the health benefits of physical activities and moderate alcohol consumption," said lead author Edward C. Suarez, PhD, associate professor of psychiatry and behavioral sciences at Duke Medicine.

"This appears to be specific to inflammation, which we know increases the risk for heart disease, so our findings suggest that depression could be a complicating risk factor," he added.

CRP is a biomarker that predicts future risk of heart disease and other chronic inflammatory conditions. It may also play a role in the formation of plaque that builds up in arteries.

Eating protein-rich breakfast reduces unhealthy snacking

Eating a breakfast rich in protein significantly improves appetite control and reduces unhealthy snacking on high-fat or high-sugar foods in the evening, according to an expert.

This could help improve the diets of more than 25 million overweight or obese young adults in the US.

Heather Leidy, an assistant professor in the Department of Nutrition and Exercise Physiology, is the first to examine the impact of breakfast consumption on daily appetite and evening snacking in young people who habitually skip breakfast.

In her study, 20 overweight or obese adolescent females ages 18-20 either skipped breakfast, consumed a high-protein breakfast consisting of eggs and lean beef, or ate a normal-protein breakfast of ready-to-eat cereal.

Every breakfast consisted of 350 calories and was matched for dietary fat, fiber, sugar and energy density. The high-protein breakfast contained 35 grams of protein.

They randomly were assigned either a high-dose vitamin D supplement or a placebo that they took daily for six months. Those who took the supplement became vitamin D sufficient and lowered the amount of insulin in their blood.
