OK

pu2. Most of them are. I'm just saying that things that aren't like that aren't really like that, not at all

pu3. The reason it's not good to grind it is because it filters out a lot of dietary fiber, although it may destroy nutrients. Eating fruits without dietary fiber increases the sugar absorption rate so much that you gain a lot of weight, confusing the hormone system, and eliminating constipation
