Green tea has been enjoyed for centuries, and its benefits have been widely touted. It is reputed to help treat many of modernity’s worst ills, including cancer, heart disease, diabetes, HIV infection, and neurodegenerative diseases. New work done in China furthers the observations that green tea can help prevent neurodegeneration. The report, published in Molecular Nutrition and Food Research, starts to elucidate the mechanism by which it does so [1].
NIH Investigators Find Link Between DNA Damage and Immunity
Researchers offer the first evidence that DNA damage can lead to the regulation of inflammatory responses, the body’s reaction to injury. The proteins involved in the regulation help protect the body from infection. The study, performed by scientists at the National Institute of Environmental Health Sciences (NIEHS), which is part of the National Institutes of Health, is one of the first studies to come out of the recently established NIEHS Clinical Research Unit (CRU).
Oxidative Stress in Children with Celiac Disease
Celiac disease is a genetic digestive disorder triggered by consumption of the protein gluten, which is found in bread, pasta, cookies, pizza crust and many other foods containing wheat, barley or rye. Researchers now report that there is a factor independent of diet that contributes to oxidative stress in celiac disease patients; children with celiac disease have higher than normal levels of two oxidative DNA damage biomarkers, regardless of what they eat [1].
Celiac disease is an autoimmune disease in which the consumption of gluten — a protein found in all forms of wheat, including spelt, kamut, semolina and triticale, as well as in barley and rye — induces an inflammatory reaction that destroys the gut. It occurs in almost 1% of the population, although in the United States as many as 97% of cases remain undiagnosed. Most autoimmune diseases are thought to be caused by an interaction between a genetic predisposition and an environmental trigger, but celiac disease is the only one for which the environmental trigger is known: gluten.
