Heads up, those of you looking for the American Dietetic Assn. The organization, made up of food and nutrition professionals, has a new name: The Academy of Nutrition and Dietetics. The name change officially happened on Jan. 1, and the decision wasn't made lightly. In a news release academy President Sylvia Escott-Stump explained the thoughts behind changing the original name, which has been in place since the group was founded in 1917. "Protecting the public's health is the highest priority of the Academy and our members, and our new name complements our focus: the nutritional well-being of the American public.

There has been lots of excitement this week as a horde of scientists released their first looks at the trillions of microbes that live in (or on) our bodies. As well as the two main papers published in Nature, a slate of reports was published in other journals, containing all kinds of tidbits. One week earlier, another slate of “microbiome” papers was published in the journal Science. We already covered the nuts and bolts of the Human Micriobiome Project report.

Being obese might up the chance of developing Type 2 diabetes, but the true risk factors may lie in how much overweight someone is and how long they've been that way. Much like figuring how numbers of cigarettes smoked and years of smoking relate to lung cancer risk, researchers set out to see how degree and length of obesity factored into the risk of getting Type 2 diabetes. They looked at data on 8,157 teens and young adults who were 14 to 21 years old at the start of a national study.

Packing on even a few extra pounds in midlife can increase the risk of developing dementia, such as Alzheimer's disease, by 70% or more, Swedish researchers reported Monday. Earlier studies had shown an increased risk from being obese, but the new research reported in the journal Neurology is the first to show that simply being overweight is enough to increase the risk. "Our results contribute to the growing evidence that controlling body weight or losing weight in middle age could reduce your risk of dementia," co-author Dr. Weili Xu of the Karolinska Institutet in Stockholm said in a statement.

To combat a growing problem with anorexia and bulimia, a new law in Israel bans fashion models who are considered unhealthily thin and requires the labeling of photos that are digitally altered to make the models look thinner. Unhealthily thin is defined as a body-mass index lower than 18.5. An example being tossed around is that a woman 5 feet 8 inches tall who weighs 120 pounds would be considered, well, not quite kosher for the cameras. That's a long way from zaftig, but certainly an improvement over the bony waifs that have too long been held up as icons of beauty.

About 18% of youths 12 to 19 are obese, as well as 20% of children 6 to 11 and 10% of those 2 to 5 years old. These Centers for Disease Control and Prevention figures date to 2008, but all indications are that those numbers are on the rise. How do you know whether your child is obese? You can't tell just by looking. One of the tools a doctor will use is a BMI growth chart that compares your child's body mass index, or BMI, calculated from his or her weight and height, with others of the same sex and age. Children who fall in the 85th to 95th BMI percentiles (meaning 85% to 95% of children have a lower BMI)

As little as one hour of low-intensity exercise a week could reduce the risk of colon polyps among people of various racial and ethnic groups, a study finds. The study, presented recently at the Digestive Disease Week meeting in Chicago, analyzed data on 982 patients who underwent colonoscopies. Polyps were found in 29.5% of the study subjects. Patients who hadn't exercised at least one hour a week had a polyp prevalence of 33.2%, while the prevalence rate among those who did exercise one hour or more was 25.3%.

When a nearly 600-pound man who boldly promoted food at a restaurant called the Heart Attack Grill dies, one of the first reactions is likely to be ... , well, not one of surprise. But then comes the news that Blair River might have died of pneumonia. Hold on. Don't order up that 8,000-calorie burger just yet. Note that there is a potential link between obesity and pneumonia. "After accounting for factors such as lifestyle and education, moderately obese men -- those with a body mass index between 30 and 34.9 -- had a 40% greater risk of pneumonia compared with those of normal weight (BMI of less than 24.9)

If obesity rates continue to climb in the U.S. as they've done in the past, about half of all men and women could be obese in 20 years, adding an extra 65 million obese adults to the country's population. The figures are from a study released Thursday in the journal the Lancet (part of a four-part obesity series) that used past trends to predict what the future might look like in the U.S. and the U.K. if people keep gaining weight at that rate. It's not a pretty picture--along with expanding waistlines may come higher disease rates and, in turn, greater healthcare costs.

Americans have increased their life expectancy by cutting back on cigarettes, but the pounds they're packing on mean that, ultimately, they could lose ground. A New England Journal of Medicine study published Wednesday looked at previous national health surveys to forecast life expectancy and quality of life for a typical 18-year-old from 2005 through 2020. Declines in smoking over the last 15 years would give that 18-year-old an increased life expectancy of 0.31 years. However, growing body mass index rates would also mean that that teen would have a reduced life expectancy of 1.02 years, giving a net life expectancy reduction of 0.71 years.
