David Zinczenko produces the “Eat This, Not That” books which show readers what foods are particularly unhealthy and what satisfying alternatives to each dish might look like. He has published the annual list of “Worst Foods” for 2010. Some of the big winners are dishes from P.F. Chang’s, Pizzeria Uno, Cheesecake Factory and IHOP. I was shocked not to see my favorite culinary abomination – KFC’s Double Down – make the list. But with the holidays fully upon us and lots of dining out for holiday parties, I thought our readers might arm themselves with this knowledge before they hit the restaurants. Enjoy!
