Raisins as effective as  chews to fuel workouts

Eating raisins may provide the same workout boost as sports chews, a new study has suggested.

Conducted by researchers at the University of California-Davis, the study evaluated the effects that natural versus commercial carbohydrate supplements have on endurance running performance.

Runners depleted their glycogen stores in an 80-minute 75 percent V02 max run followed by a 5k-time trial. Runners completed three randomized trials (raisins, chews and water only) separated by seven days. The study found that those that ingested raisins or sports chews ran their 5k on average one minute faster than those that ingested only water.

Eating raisins and sports chews promoted higher carbohydrate oxidation compared to water only.

Ginseng-enriched milk helps improve cognitive function

Incorporating ginseng into food has been a challenge because it has a bitter taste, and food processing can eliminate its healthful benefits.

Now, a group of scientists has formulated low-lactose functional milk that maintained beneficial levels of American ginseng after processing. An exploratory study found the product was readily accepted by a niche group of consumers.

“Our goal was to develop low-lactose milk that could be consumed by the elderly to improve cognitive function,” said lead investigator S. Fiszman, PhD, of the Instituto de Agroquimica y Tecnologia de Alimentos (IATA), Consejo Superior de Investigaciones Cientificas (CSIC), Patema (Valencia), Spain. “Consumers who were interested in the health benefits of ginseng rated our product quite highly,” they noted.

Because older people frequently have trouble digesting milk products, the researchers developed a low-lactose formula. American ginseng was added, and then the milk was sterilized by ultra-high temperature processing (UHT), which prolongs shelf life.

Cheese slashes diabetes risk by 12 per cent
Eating just two slices of cheese a day can cut the risk of developing type 2 diabetes by 12 per cent, researchers say.

The findings go against current health guidelines, which advise cutting back on dairy products and other high-fat foods to help prevent the illness.
British and Dutch researchers looked at the diets of 16,800 healthy adults and 12,400 patients with type 2 diabetes from eight European countries, including the UK.

The study found that those who ate at least 55g of cheese a day – around two slices – were 12 per cent less likely to develop type 2 diabetes. The risk fell by the same amount for those who ate 55g of yoghurt a day.

But despite the latest findings, campaigners warned against  gorging on cheese and other dairy products in the hope of warding  off diabetes.

“It is too simplistic to concentrate on individual foods,” the Daily Mail quoted Dr Iain Frame, director of research at the charity Diabetes UK, as saying.
