cutting out grains is very hard.

Certainly not. You just stop eating them. I stopped about half a year ago and never looked back. Well, my health was reasonably good so I can't say it improved dramatically since. However, I had some digestion issues before, these have been eliminated. This alone is enough for me to justify dropping grains, as digestion issues may become annoying and embarrassing at times. :)

The problem with "just stop" is that it interferes with a conventional lifestyle where you can tolerate other people's choices of food(which, the vast majority of the time, will contain grains or dairy).

I lean towards the paleo style myself, but I tolerate a little bit of compromise, and a little bit more when I'm with a friend. But I know intuitively how bad it is now - the effects I feel 15-30 minutes after consumption are mild but predictable.
