My latest San Francisco Chronicle column: Gluten Intolerance

My once-every-three-weeks column for the San Francisco Chronicle is set up as a Q and A.  I don’t get many questions through the column, but the few that do come in are often quite challenging.  This one is from a school chef wondering how to deal with kids who might be gluten intolerant – and whether gluten intolerance is becoming more common.  Interesting questions!  Here’s what I had to say about them.  If you have questions about food and nutrition that you’d like me to answer, send them to food@sfchronicle.com (put Marion Nestle in the subject line).
