• Do More People Have Celiac Disease in the North vs the South?

Do More People Have Celiac Disease in the North vs the South?

A higher proportion of persons living at latitudes of 35° North or greater have celiac disease or avoid gluten than persons living south of this latitude, researchers report in the June issue of Gastroenterology. This difference was independent of race or ethnicity, socioeconomic status, or body mass index. Several autoimmune

  • What Causes Wheat Sensitivity in People Without Celiac Disease?

What Causes Wheat Sensitivity in People Without Celiac Disease?

Gluten-containing cereals have high concentrations of amylase-trypsin inhibitors (ATIs), which activate innate immunity via the toll-like receptor 4 (TLR4), researchers report in the April issue of Gastroenterology. These ATIs are resistant to proteases and heat, and increase intestinal inflammation by activating intestinal and mesenteric lymph node myeloid cells. Wheat is

  • Can Your Diet Affect Your Risk for Gallstone-related Pancreatitis?

Can Your Diet Affect Your Risk for Gallstone-related Pancreatitis?

Consumption of red meat, saturated fat, and cholesterol increase risk for gallstone-related acute pancreatitis, researchers report in the February issue of Clinical Gastroenterology and Hepatology. Dietary fiber protects against acute pancreatitis—related and unrelated to gallstones—whereas coffee protects against acute pancreatitis not associated with gallstones, the study of thousands of patients

  • Can Vitamin D Affect Risk of Ulcerative Colitis Relapse?

Can Vitamin D Affect Risk of Ulcerative Colitis Relapse?

Serum levels of vitamin D of 35 ng/mL or less in patients with ulcerative colitis (UC) in clinical remission are associated with disease relapse, researchers report in the February issue of Clinical Gastroenterology and Hepatology. Increasing patients’ levels of vitamin D might reduce their risk for UC relapse. Vitamin D

  • Is Dietary Fiber OK for Patients With Crohn’s Disease or Ulcerative Colitis?

Is Dietary Fiber OK for Patients With Crohn’s Disease or Ulcerative Colitis?

Intake of dietary fiber reduces risk of disease flares in patients with Crohn’s disease, but not ulcerative colitis, researchers report in the August issue of Clinical Gastroenterology and Hepatology. Recommendations to limit dietary fiber should therefore be re-evaluated. Inflammatory bowel diseases (IBD) have been associated with an abnormal mucosal immune response to

Peanut Consumption in Infancy not Only Prevents Allergy but Effects Persist After Avoidance

The benefits of regularly consuming peanut-containing foods early in life to prevent the development of peanut allergy persist even when subjects stopped peanut consumption for 1 year, a clinical study found. Early introduction of peanuts to infants at high risk for allergy was previously shown to prevent peanut allergy. In a

  • Can Nutritional Therapy Help Patients with Minimal Hepatic Encephalopathy?

Can Nutritional Therapy Help Patients with Minimal Hepatic Encephalopathy?

Nutritional therapy for patients with cirrhosis and minimal hepatic encephalopathy (MHE) not only improves their nutritional status, but increases cognitive function, health-related quality of life (HRQOL), and liver function and reduces hospitalization, researchers report in the March issue of Clinical Gastroenterology and Hepatology. HE is a spectrum of neuropsychiatric abnormalities that develops in

  • 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?

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
