I'm secretly hoping that all the creepy news about Taco Bell and Olive Garden will finally lead people to healthy (or -ier) food. Sadly, the organic produce section at my favorite grocery isn't nearly as popular as the pro-pesticide aisle.
So perhaps baby steps is the best approach.
If I had to pick one, singular item for a desert isle scenario, it would definitely be organic milk. Preferably Horizon. (Completely realize that breakfast cereals and dairy-spiked coffee would not be available, but just go with it.)
It's hormone-free. Produced by farmers dedicated to making you better products. And aside from the adorable logo on the carton, my favorite brand has a great, informative website.
Go ahead. Toss that white stuff you got at 7-Eleven and splurge.
