Sorry, I responded before reading your other comments. The oils vs fiber is true, but probably not your friend's solution. I can say that my mother developed lactose intolerance, but she got over it by drinking only organic milk and it went away. There are some that recommend kefir or organic living yogurt to overcome lactose indifference, but I don't have personal experience with that. Good luck.
