Very good points, Scott. You are correct when you point out that food can be a "charged" issue — look at all the heated discussions on these forums!!
When I worked at the DM clinic, we saw all different types of eating, and the philosophy was "if it aint broke, don’t fix it". I had patients who followed Atkins and successfully lowered their BG levels, and I had patients who ate what they wanted and relied on meds. (not recommended, but there are a lot of DM patients who won’t change their eating habits…)
So, yeah, maybe a plant or so other non-offensive non-food item! [:)]
