I cook my food, of course (lentils, beans and stuff like that). And it also took me some time to figure out what is what I call an optimal diet. But I always have to laugh at the many prejudices. I'm rarely sick (although I travel all the time and meet a lot of people), plus I do a lot of exercise and at a high level. I can now tell that I am much happier and have overcome all the bad since I live vegan, but of course that's nonsense.
