• Intestinal Microbiota Protect Children From Malnutrition

Intestinal Microbiota Protect Children From Malnutrition

Three new studies show that intestinal bacteria protect children from malnutrition and allow them to benefit from breast milk. Malnutrition, the world’s leading cause of death before age 5, is a persistent challenge that is not always remedied by improvements in nutrition. This is because the community of gut microbes regulate growth,

Should All Patients with IBS be Screened for Celiac Disease?

Screening patients with irritable bowel syndrome (IBS) or other functional gastrointestinal disorders for celiac disease isn’t much more effective than screening the general population, researchers report in the November issue of Clinical Gastroenterology and Hepatology. Celiac disease produces symptoms similar to those of IBS, such as lower abdominal pain, diarrhea,

6000-Calorie Diet Reveals Mechanisms of Obesity-Linked Insulin Resistance

A study in which researchers place healthy individuals on 6000-calorie per day diets has identified biologic changes that take place during the early stages of obesity and could lead to insulin resistance. The study, published in the 9 September issue of Science Translational Medicine, pinpoints oxidative stress as the potential

  • What Causes Different Types of Fatty Liver Disease?

What Causes Different Types of Fatty Liver Disease?

Hepatic steatosis and steatohepatitis are increasing in prevalence, and can progress to histologically identical, more severe liver disease. They are associated with 3 main factors: alcohol, obesity or metabolic syndrome, and exposure to toxins. Researchers review the similarities, differences, and pathogenic mechanisms of alcohol-associated steatohepatitis (ASH), nonalcoholic steatohepatitis (NASH), and toxicant-associated fatty liver

Does Weight Loss Resolve Fatty Liver Disease?

Two separate studies in the August issue of Gastroenterology show that weight loss, via diet or bariatric surgery, reduce features of non-alcoholic steatohepatitis (NASH). Eduardo Vilar-Gomez et al associated extent of weight loss, produced by lifestyle changes, with level of improvement in histologic features of NASH. The highest rates of NASH reduction

Special Issue: Food, the Immune System, and the GI Tract

The digestion of food and absorption of nutrients is the principal role of the gastrointestinal (GI) tract—everyone wants to know what we should eat and how it affects our body. Interactions between food and the immune system affect our microbiome, development of food allergies, nutrition, risk for inflammatory disorders or cancer, and even

  • Veggie Diets, Especially With Fish, Cut Colorectal Cancer Risk

Veggie Diets, Especially With Fish, Cut Colorectal Cancer Risk

A vegetarian diet, especially one that includes fish, significantly reduces the risk of colorectal cancer, a large new study reports. These findings could lead to new strategies for cancer prevention. In the Adventist Health Study 2, researchers had 77,659 men and women from Seventh-day Adventist churches nationwide complete well-validated questionnaires

  • Food Emulsifiers Increase Intestinal Permeability to Promote Inflammation

Food Emulsifiers Increase Intestinal Permeability to Promote Inflammation

Food additives commonly used to thicken and stabilize processed foods disrupt the intestinal microbiota to cause inflammation, researchers found in a study of mice. Emulsifiers are added to foods to hold together mixtures of fat and water, which would otherwise separate. Healthy mice fed a diet containing commonly used emulsifiers (1%

Celiac Disease Risk Not Affected by Early Diet

Two studies have shown that neither breastfeeding nor timing the start of gluten-containing foods makes a difference in development of celiac disease in children at risk. The AP reported that the studies, published October 2 in the New England Journal of Medicine, show that there is no early window of

How Does a High-Fat Diet Contribute to Pancreatic Cancer?

A high-fat diet can promote development of pancreatic cancer, but cyclooxygenase-2 (COX2) inhibitors prevent this process, according to a mouse study published in the December issue of Gastroenterology. The mechanisms appear to involve activation of oncogenic KRAS and upregulation of COX2, which promotes pancreatic inflammation. Increased body mass index and
