The True Food Network is a blog that works in conjunction with the Center for Food Safety. If you haven't checked them out, please do.
There is so much you can easily learn and it will help you be more informed and it will keep you abreast of the news that is important to keeping your food supply healthy. What I like is that they have a "take Action" section that reminds you to contact your political representative, and the FDA, to let them know what you will or won't tolerate in the food supply.
It is important to become involved. It is important to stay imformed and then let those around you know what you have learned. Eating will become a much more enjoyable thing when you understand whatyou are eating and how it may possibly affect you in the future.
