Nuts cause allergies.
Women who dine nuts during pregnancy - and who aren't allergic themselves - are less apt to to have kids with nut allergies, a creative look suggests. Dr Michael Young, an associate clinical professor of pediatrics at Harvard Medical School, and colleagues composed evidence on more than 8200 children of mothers who took role in the Nurses' Health Study II. The women had reported what they ate before, during and after their pregnancies. About 300 of the children had sustenance allergies kahani. Of those, 140 were allergic to peanuts and tree nuts.
The researchers found that mothers who ate the most peanuts or tree nuts - five times a week or more - had the lowest jeopardize of their progeny developing an allergy to these nuts. Children of mothers who were allergic to peanuts or tree nuts, however, did not have a significantly decrease risk, the bone up found. The reveal was published online Dec 23, 2013 in the minute-book JAMA Pediatrics skinbrightener. The gauge of US children allergic to peanuts more than tripled from 0,4 percent in 1997 to 1,4 percent in 2010, according to offing dirt included in the study.
Many of those with peanut allergies also are allergic to tree nuts, such as cashews, almonds and walnuts, the researchers said. "Food allergies have become epidemic," said Dr Ruchi Gupta, an confederate professor of pediatrics at the Northwestern University Feinberg School of Medicine. "Our own studies show that 8 percent of kids in the United States have a viands allergy - that's one in 13, about two in every classroom," said Gupta, the founder of an accompanying gazette editorial.
Yet why this prevalent is phenomenon remains a mystery. "We do not have any manifestation as to what is causing this boost in comestibles allergy. It's some approachable of genetic and environmental link". The untrodden findings do not prove or affirm a cause-and-effect relation between women eating nuts during pregnancy and farther down allergy endanger in their children. "The results of our over are not vigorous enough to return dietary recommendations for in a family way women.
Young said the findings do, however, sum up to the growing statement that anciently introduction of foods increases the increase of insensitivity and reduces the risk of allergies. "Our information should reassure pregnant women that they could have a bite nuts without causing the offspring to be allergic to nuts. Gupta agreed. "With the modern widen in food allergies, I deem mothers are fearful that eating certain foods may cause their young gentleman to develop that food allergy.
But that isn't backed by any data. "Mothers should not be horrific of eating doubtless foods and should go on with their regular cravings and their biweekly diets and not avoid things to try to shield their child from allergy. This study suggests that divulging to nuts early in life might keep kids from developing an allergy to them - a theory that also has been linked to other foods to which kids are commonly allergic.
So "The facer is that we do not have enough acrid data to endorse this. The eight foods to which children are most commonly allergic are peanuts, milk, eggs, tree nuts, shellfish, fin fish, wheat and soy. Children often outgrow these allergies. "The ones that are most commonly outgrown are egg and bleed allergies.
Things as though nuts and fish and shellfish - only about 10 percent to 20 percent of grass roots outgrow those allergies". The melodramatic extension in victuals allergies is not just an American phenomenon, but is being seen worldwide. "We are unquestionably considering higher rates in Canada, Europe, Japan, China, India - all over the world apotik yang menjual vigrx plus jakarta. Gupta said she is sanguine that during the next decade it will be discovered why this develop in foodstuffs allergies is occasion and what can be done about it.
