Study: 50 percent increase in food allergies for kids Updated: Saturday, August 3, 2013 | (NEWSCHANNEL 3) - A study released Thursday shows more kids are getting allergies.The study says one in 20 kids now have food allergies. That's a 50 percent increase from the late 1990's.For eczema and other skin allergies it's one in eight children, which is an increase of 69-percent.The study found no increase, however, in hay fever or other respiratory allergies.Experts aren't sure what's behind the increase. One of the main ideas argues that there is a downside to America's culture of disinfection and overuse of antibiotics, saying we live in too clean of homes, which leaves them more sensitive to things that can trigger allergies. The CDC report also found that: Food and respiratory allergies are more common in higher-income families than the poor. Eczema and skin allergies are most common among the poor. And more black children have the skin problems, 17-percent, compared to 12-percent of white children and about 10-percent of Hispanic children.The CDC says some of the statistics may reflect a recent change in the recommendations for when young children should first eat certain foods.In families with a history of eczema or food allergies parents used to be advised to wait for years before introducing their young children to foods tied to severe allergies like peanuts, milks and eggs. But doctors now say research suggests that allergies are more likely in those kids when the foods were delayed.If you want to see the full report, click here.
