Researchers Uncover Surprises About Celiac Disease

Posted 31 May 2016 by Drugs.com

TUESDAY, May 31, 2016 – New research has revealed some surprising findings about who develops celiac disease in the United States. The study found that it's most common among people whose ancestors came from India's Punjab region. Previously, experts thought celiac mostly affected white people with European ancestry. Celiac also seems to affect men and women equally, regardless of ethnicity, the researchers said. "It is now recognized as one of the most common hereditary disorders worldwide," said the study author, Dr. Benjamin Lebwohl, in a news release from the American Gastroenterological Association. Lebwohl is an assistant professor of medicine and epidemiology at the Celiac Disease Center at Columbia University Medical Center, in New York City. Celiac is an immune-based disorder that causes damage to the small intestine if genetically susceptible people eat foods containing ... Read more

Coming Soon: A Test to Gauge Your Obesity Risk?

Posted 30 Apr 2015 by Drugs.com

THURSDAY, April 30, 2015 – Researchers say they have successfully linked certain byproducts of digestion to the risk of excess body fat. Eventually, these findings might lead to more personalized interventions for people who are identified as "at-risk" for obesity, including diet, exercise or supplements, such as probiotics. The team of international researchers constructed an in-depth biochemical "map" that tracked the way food is processed and broken down by the body. This enabled the investigators to take a snapshot of the end product of digestion: molecules known as metabolites. More than two dozen of these metabolites were highly correlated with diet. Some were associated with having a high body mass index (BMI), an estimated measure of body fat, while others were associated with having a low BMI. The study authors said their research suggests that obesity risk is actually driven ... Read more

Americans' Gut Bacteria Lack Diversity, Researchers Find

Posted 16 Apr 2015 by Drugs.com

THURSDAY, April 16, 2015 – Americans have fewer types of intestinal bacteria than people in less-developed countries, according to a new study. The likely cause? Bacteria are less likely to be passed from person to person due to better sanitation and cleaner drinking water in the United States, the researchers reported in the journal Cell Reports. "These findings suggest that lifestyle practices that reduce bacterial dispersal – specifically sanitation and drinking-water treatment – might be an important cause of microbiome alterations," senior author Jens Walter, from the department of agricultural, food and nutritional science at the University of Alberta in Canada, said in a journal news release. Bacteria naturally reside in the intestines and play an important role in health, but recent research has shown that a modern – or western – lifestyle reduces the diversity of these ... Read more
