Aid for travelers with food allergies

If you or your kids stay away from gluten — an estimated one in 16 Americans are sensitive to the protein found in wheat and other grains — dining out can be a challenge. Ditto for other food allergies. There's now a suite of mobile apps for the iPhone and iPad that help you navigate allergy- and gluten-free fast food, restaurant dining and more. From Kim Koeller and Robert La France, authors of the 2011 Let's Eat Out with Celiac (R & R Publishing, $26.95) and the pocket Multi-Lingual Phrase Passport, the apps let you chew in peace. n
