I was on vegan for nearly 8 years, during that period, I tried with pure vegan, and then I changed to Macrobiotic. The thing with plant based diet is that initially you felt good.
However over the time, you need to be careful because of the many toxins in plants. I would recommend you to read the Plant Paradox, there are good stuff there.
In fact, many agri cultures have traditional ways to handle the toxins in plants, such as cooking (various types), fermentation, and processing to reduce the effects.
