My dh has high blood pressure (under control with medication) and his meeting with a specialist basically went, "You need to lose weight and exercise more." The specialist gave more specific advice about diet, but the point is, I now have an "expert" to back up my attempts to get dh to eat healthier.
So, I'm adjusting our diet from the Canada Food Guide (which I was only following loosely) to the DASH Diet (Dietary Approaches to Stop Hypertension). It's not a big change for me, but I'm really looking forward to it. Lent starts on Wednesday, and I plan to limit meat (except fish) to Sundays.
