Why I went vegan.  I had been vegetarian on and off in the past, using meat sparingly if at all and animal products, like cheese, eggs and dairy for many years in recipes.  This all changed with the reading of The China Study.  I am asking everyone to read this book, what you do after, ie whether you change your diet or not is of course up to you.  I just want to make sure everyone has the information in Dr. Campbell's (no relation) book.
I wasn't sure I could do it, even though the health implications were clear.  I thought, I will begin with one week and see how I do.  One week turned to one month and now on my second month, I know it sounds cliche, but I feel better.
