Funding Opportunity for Research on Biological Signatures of Gut-Derived Metabolites

Did our parents have the right idea when they told us to eat more fruits and vegetables? Maybe so! Evidence has begun to build that the foods we eat (including the natural compounds in fruits and veggies), the flora in our digestive systems, and our basic biological functions all intersect to influence our overall health. Recently, NCCIH released a Funding Opportunity Announcement (FOA), Biological Signatures of Diet-Derived Microbial Metabolites, for projects to study several aspects of this question.

Morbid obesity: Gastric bypass and sleeve gastrectomy are comparable

In Switzerland, 5,500 operations to combat morbid obesity are conducted every year. Gastric bypasses and sleeve gastrectomy operations perform similarly: patients lose two-thirds of their excess weight in the long term. When it comes to gastric acid reflux, the bypass clearly shows better results.

Bariatric surgery prolongs lifespan in obese

Obese, middle-age men and women who had bariatric surgery have half the death rate of those who had traditional medical treatment over a 10-year period, reports a study that answers questions about the long-term risk of the surgery. Previous studies looking at this question were indefinite because follow-up data was limited due to high costs and patients dropping out.

Improvements in mortality rates are slowed by rise in obesity in the United States

With medical advances and efforts to curb smoking, one might expect that US life expectancy would improve. Yet there's been a reduction in the rate of improvement in American mortality during the last three decades.Researchers say a rise in obesity is to blame, slowing declines in death rates by a half-percentage point per year. The scientists estimate that rising obesity was about twice as important for mortality trends as a decline in smoking.

Fast food makes the immune system more aggressive in the long term

The immune system reacts similarly to a high fat and high calorie diet as to a bacterial infection. Unhealthy food seems to make the body's defenses more aggressive in the long term. Even long after switching to a healthy diet, inflammation towards innate immune stimulation is more pronounced. These changes may be involved in the development of arteriosclerosis and diabetes.

Mediterranean diet may help protect older adults from becoming frail

An analysis of published studies indicates that following the Mediterranean diet may reduce the risk of frailty in older individuals. The findings suggest that a diet emphasizing primarily plant-based foods -- such as fruits and vegetables, whole grains, legumes, and nuts -- may help keep people healthy and independent as they age.

Teens show decreased risk for heart disease later in life after bariatric surgery

Adolescents with severe obesity who had bariatric surgery showed significant improvements in cardiovascular disease risk factors, according to this study. Prior to bariatric surgery, 33 percent of the study participants had three or more defined cardiovascular disease risk factors. However, three years post-surgery only 5 percent of study participants had three or more risk factors; representing significant reduction in the overall likelihood of developing cardiovascular disease later in life.
