Finished day 3 of my 21-day vegan diet. So far, so good. I've never been a big meat eater, so it hasn't been much of a change that way. It's the dairy that I miss. I LOVE ice cream and anything sweet and creamy. This will be what I will miss but I am finding foods to add into my diet that satisfy those same cravings thus crowding out the ones that are not so good for me.
I also read an article in the NY Times about whether or not organic produce has advantages over conventional produce. http://www.nytimes.com/2012/09/04/science/earth/study-questions-advantages-of-organic-meat-and-produce.html?_r=3&smid=tw-share
This sort of news in the mainstream media is scary to me. Don't trade in your organic produce just yet. It doesn't matter if an organic strawberry or blueberry has less vitamin c than a conventional one; it is free from pesticides and THAT'S a good thing. People don't buy organic produce because they are more nutritious (I see organic junk food sold all the time - it doesn't mean it's good for you though), they pay more because they are free from pesticides. Animals raised for organic meat are not fed any animal products while being raised and must also not be given any antibiotics or growth hormones.
My advice, read everything with a critical eye. Hear it with a critical ear. Even what I write. Do your research. Not just from one source. Make an informed decision and then live with the benefits or consequences.
