In this week’s nutrition news: Check Twitter and Facebook before your next visit to the farmers' market, food allergy testing to be standardized and meet the White House pastry chef.

Meet Bill Yosses—he’s the 57 year old chef in charge of making desserts for the White House. Many question what he’s been doing since Mrs. Obama requested that dessert be an occasional treat and only served in small portions. Besides making pastries for morning meetings in the West Wing, Mr. Yosses fills his busy 12 hour days by taking on additional tasks—including beekeeping, weeding and creating the perfect pie crust (which I’d love to try!).

Have you noticed the sudden increase in food allergies? So has the federal government---so they dug a little deeper to find out why. Although about 30 percent of the population believes they have food allergies, in reality not all do. Many folks who were diagnosed as a child shed their allergies as an adult or it’s been found that tests like finger pricking and tiny injections are only 50 percent accurate. The National Institute of Allergy and Infectious Diseases is on a mission to create one standard for food allergy testing—they expect to write up a draft by June.
