WHAT'S THE BUZZ


Regular exercise good for diabetics

Patients with Type 2 diabetes should do at least two-and-a-half hours per week of moderate-intensity or one-and-a-half hours per week of vigorous-intensity aerobic exercises, plus some weight training, to reduce their cardiovascular risk, researchers suggest.

“Given the observed increases in Type 2 diabetes in adults over the last few decades in developed countries, and the increasing numbers of overweight and obese individuals throughout the world, we must look at ways to reduce the cardiovascular complications of diabetes, and exercise is one of those ways,” said Thomas H Marwick, University of Queensland School of Medicine in Brisbane, Australia.

According to an American Heart Association scientific statement, diet and exercise can prevent or slow the development of Type 2 diabetes and produce clinically significant improvements in blood sugar control and cardiovascular risk factors in people with the condition.

Low-carb diet helps lose weight

A diet low in calories and carbohydrates but high in plant-based proteins may promote weight loss and improve cholesterol levels, according to study.

In the study, researchers found that overweight individuals who ate such a diet for four weeks lost weight and experienced improvements in blood cholesterol levels and other heart disease risk factors.

They found that a high-carbohydrate, low-fat vegetarian diet also resulted in weight loss but without the additional cardiovascular benefits.

David J A Jenkins, of St Michael’s Hospital and the University of Toronto, Ontario, Canada, and colleagues tested the effects of a low-carbohydrate diet high in vegetable proteins from gluten, soy, nuts, fruits, vegetables, cereals and vegetable oils among overweight men and women with high LDL cholesterol levels.

The low-carbohydrate diet also appeared to produce beneficial changes in levels and ratios of apolipoproteins, proteins that bind to fats.

Sleep linked to high, worsening BP

A new study has shown that middle-aged adults who sleep fewer hours are more likely to have high blood pressure and to experience adverse changes in blood pressure over time.

Sleep deprivation is linked to an increased activity in the sympathetic nervous system, which controls the body’s stress response. Over time, this activation could contribute to high blood pressure.

“Identifying a novel lifestyle risk factor for high blood pressure could lead to new interventions to prevent or reduce high blood pressure,” the authors said.

“Laboratory studies of short-term sleep deprivation have suggested potential mechanisms for a causal link between sleep loss and hypertension,” they added.

Cabbage is best natural Viagra

Say goodbye to Viagra, for experts have discovered a more natural way of boosting life in bed-cabbage.

According to Croatian nutritionist Dr Lejla Kazinic Kreho, pickled cabbage nearly works the same wonders as the popular drug.

Boffins at King’s College, London, found that saurkraut played a powerful role during the research. Lejla discovered just how powerful saurkraut could be in an investigation into the best natural Viagra.

She said: “Pickled cabbage is the best natural Viagra.”

She added: “I can only suggest all men try it. Eat cabbage twice a day and observe how your sexual power increases.”
