Leanwashing
Leanwashing is like whitewashing but is done to processed food marketing materials which purport good health and nutritional claims when the product is junk or shall I say has more that's bad about it than it has good.
These products are targeted to children, the issues with marketing to children are another whole can of worms to get upset about.
You can upload your own information. I can just see myself snapping photos with my iPhone at the grocery store and submitting them to the website. Actually I choose not to spend my time that way but the site was enlightening to see nonetheless.
It's actually one of those good websites to share on Facebook then let have comments with your friends. Usually in those exchanges someone learns something, which is a good thing.
