 The latest published papers from the world of fitness, nutrition and exercise science discuss a variety of topics, including obesity drugs, a correlation between dietary advice and peanut allergy in infants, and the right proportion of fruits and veg in the 5-a-day recommendation. The geeks will also find exciting developments. Here are the highlights:
Decrease in peanut allergy among infants after guideline changes Changes to food allergy guidelines has led to a 16 per cent decrease in peanut allergy among infants, according to new study.

Source: University of Pennsylvania School of Medicine The right '5-a-day' mix is 2 fruit and 3 vegetable servings for longer life Higher consumption of fruits and vegetables is associated with a lower risk of death in men and women, according to data representing nearly 2 million adults. Five daily servings of fruits and vegetables, eaten as 2 servings of fruit and 3 servings of vegetables, may be the optimal amount and combination for a longer life. These findings support current U.S. dietary recommendations to eat more fruits and vegetables and the simple public health message '5-a-day.' Source: American Heart Association Deciphering the genetics behind eating disorders By analysing the genome of tens of thousand people, a team has discovering similarities between the genetic bases of anorexia nervosa, bulimia nervosa or binge-eating disorder, and those of psychiatric disorders. Eating disorders differ in their genetic association with anthropometric traits. Thus, genetic predisposition to certain weight traits may be a distinctive feature of anorexia nervosa, bulimia nervosa or binge-eating disorder.

Researchers observed that the intake of those extracts can reduce facial dysmorphology in children with Down syndrome when taken during the first three years of life. Additional experimental research in mice confirmed the positive effects at low doses. However, the researchers also found that high doses can disrupt facial and bone development. Source: KU Leuven Less inflammation with a traditional Tanzanian diet than with a Western diet Study shows differences between western and traditional diet Urban Tanzanians have a more activated immune system compared to their rural counterparts. The difference in diet appears to explain this difference: in the cities, people eat a more western style diet, while in rural areas a traditional diet is more common. A team of researchers believe that this increased activity of the immune system contributes to the rapid increase in non-communicable diseases in urban areas in Africa.

UC San Diego nanoengineers call it a ''wearable microgrid''-- it combines energy from the wearer's sweat and movement to provide sustainable power for wearable devices.
