Marion Nestle is well respected for her work explaining the relationship between the food industry and politics. She has also written a book, What to Eat, which apparently tries to decode all the mixed nutritional messages out there. Her books are on my "to read" list, but I was pleased to hear she has a blog called What to Eat. I can't really handle any heavy reading now, but her blog is a great resource for me. Personally, I like how she addresses her topics in a non-threatening way as well as encourages participation from her readers.
