(October 10, 2008 - Insidermedicine) From Barcelona - According to health experts from the Wildlife Conservation Society, climate change may allow several diseases to spread into new regions around the world. The diseases identified have been dubbed the "deadly dozen" and include the avian flu, ebola, cholera and tuberculosis. The researchers suggest that as climate change disturbs weather patterns it will have a significant effect on the health of wild animals and, consequently, on the health of humans and global economies.

From Washington - The U.S. Department of Health and Human Services has released new guidelines to make it easier for people to keep fit. The new recommendations suggest getting about 5 hours of moderate exercise, or 2.5 hours of intensive exercise each week to stay healthy. The guidelines also state that physical activity can help reduce the risk of dying early from heart disease, stroke, high blood pressure, type 2 diabetes and depression.

And finally, from New York - According to research in the journal Obesity, those who are obese behave differently in buffet restaurants than those of normal weight. In a study of 213 people at 11 all-you-can-eat Chinese buffets, researchers found that 42% of obese diners faced the buffet while eating, compared to 27% of normal weight diners. In addition, overweight diners sat about 16 feet closer to the food, used larger plates, and ate with forks instead of chopsticks - factors that can all contribute to overeating.
