Individuals who eat a gluten-free weight loss plan could also be in danger for elevated publicity to arsenic and mercury -- poisonous metals that may result in heart problems, most cancers and neurological results, in response to a report within the journal Epidemiology.
Gluten-free diets have change into in style within the U.S., though lower than 1 % of Individuals have been recognized with celiac illness -- an out-of-control immune response to gluten, a protein present in wheat, rye and barley.
A gluten-free weight loss plan is advisable for individuals with celiac illness, however others usually say they like consuming gluten-free as a result of it reduces irritation -- a declare that has not been scientifically confirmed. In 2015, one-quarter of Individuals reported consuming gluten-free, a 67 % enhance from 2013.
Gluten-free merchandise usually include rice flour as an alternative choice to wheat. Rice is thought to bioaccumulate sure poisonous metals, together with arsenic and mercury from fertilizers, soil, or water, however little is thought in regards to the well being results of diets excessive in rice content material.
Maria Argos, assistant professor of epidemiology within the UIC Faculty of Public Well being, and her colleagues checked out knowledge from the Nationwide Well being and Vitamin Examination Survey trying to find a hyperlink between gluten-free weight loss plan and biomarkers of poisonous metals in blood and urine.
They discovered 73 contributors who reported consuming a gluten-free weight loss plan among the many 7,471 who accomplished the survey, between 2009 and 2014. Contributors ranged in age from 6 to 80 years outdated.
Individuals who reported consuming gluten-free had greater concentrations of arsenic of their urine, and mercury of their blood, than those that didn't. The arsenic ranges had been nearly twice as excessive for individuals consuming a gluten-free weight loss plan, and mercury ranges had been 70 % greater.
"These outcomes point out that there may very well be unintended penalties of consuming a gluten-free weight loss plan," Argos stated. "However till we carry out the research to find out if there are corresponding well being penalties that may very well be associated to greater ranges of publicity to arsenic and mercury by consuming gluten-free, extra analysis is required earlier than we are able to decide whether or not this weight loss plan poses a major well being danger."
"In Europe, there are rules for food-based arsenic publicity, and maybe that's one thing we right here in the US want to think about," Argos stated. "We regulate ranges of arsenic in water, but when rice flour consumption will increase the chance for publicity to arsenic, it will make sense to control the steel in meals as properly."

Mediterranean diet with virgin olive oil may boost 'good' cholesterol

High levels of low-density lipoproteins (LDL -- the "bad cholesterol") and triglycerides, a type of blood fat, are associated with an increased risk of heart and blood vessel diseases. HDL cholesterol is associated with a lower risk because these lipoproteins help eliminate the excess cholesterol from the bloodstream. "However, studies have shown that HDL doesn't work as well in people at high risk for heart attacks, strokes and other cardiovascular diseases, and that the functional ability of HDL matters as much as its quantity," said senior study author Montserrat Fitó, M.D., Ph.D., and coordinator of the Cardiovascular Risk and Nutrition Research Group at the Hospital del Mar Medical Research Institute in Barcelona and at the Ciber of Physipathology of Obesity and Nutrition (CIBEROBN), Spain. "At the same time, small-scale trials have shown that consuming antioxidant-rich foods like virgin olive oil, tomatoes and berries improved HDL function in huma...

Worm gene could be key to developing obesity treatment

The team has discovered a gene that triggers a feeling of fullness, as well as the need to sleep after eating. A similar gene is found in people, opening up the potential to develop a drug that could help control obesity by reducing appetite and increasing the desire for exercise. The team, led by Associate Professor Roger Pocock at the Monash Biomedicine Discovery Institute and his colleagues at the University of Copenhagan, published their results today in the  Proceedings of the National Academy of Sciences , a prestigious US journal. Associate Professor Pocock and his team discovered a gene, encoding a transcription factor called ETS-5, which controls signals from the brain to the intestines. Associate Professor Pocock explained that when the intestine had stored enough fat, the brain would receive the message to stop moving, effectively putting the worm to sleep. "When animals are malnourished they seek out food by roaming their environment. When they're well fed...

Avoiding medications that promote weight gain when managing obesity

In the paper, published Feb. 10 in  Gastroenterology , investigators from the Comprehensive Weight Control Center at Weill Cornell Medicine underscore the necessity for physicians to evaluate the potential side effects and interactions of medications they prescribe for patients with obesity, and to familiarize themselves with alternatives that may limit weight gain or may even assist with weight loss. "Physicians know that some medications can increase weight, but they don't always know what alternatives are out there," said lead author Dr. Leon Igel, an assistant professor of clinical medicine in the Division of Endocrinology, Diabetes and Metabolism at Weill Cornell Medicine. "We want physicians who treat patients with obesity to feel more comfortable prescribing these alternatives. Our paper looks at how to practically manage patients with obesity by prescribing the optimal medications for them." Numerous factors contribute to obesity and the body's...
