You'll never hear me make a case for artificial sweeteners, but we have been ingesting (losds of) beer and bread since the days of Sumer, so I do have my doubts over the absence of grain on your pyramid. But I am biased by my own perceptions. As long as I am in good health, at the end of the day I wouldn't be swayed anyhow into abstaining from grains. What's a Netherlands without jenever, haha?
