It depends. With my weightlifting regimen AI says I should be eating a couple hundred grams of protein a day, which is ridiculous. I generally don't get to 100 and I suspect my kidneys thank me for it.
But I'm all for getting rid of as many artificial ingredients as possible. My general rule is if I read the ingredients and there's something I don't recognize as food in its own right or as natural it goes back on the shelf.
