Hey John, I notice that there are some vegetables that I always prefer. Perhaps my body knows it needs some nutrients from those vegetables and I should pay attention to what it needs(within reason). For example zucchinni and squash are what my appetite usually prefers. However when I am working out more, my preferences do change an that is probably normal because I am going to need more carbohydrates.
I have cut out tomatoes, even though I used to like them, and now after awhile I seem to have less joint aches. Take this with a grain of salt though because at the same time I also avoided cheese products at the same time.
Feel free to post anything on beans (especially pintos) as I have some dishes that I like to eat with those on the side.
