Why Some Like it Hot by Gary Nabhan is an interesting book focusing on human microevolutionary adaptations to diet and how eating traditional foods is healthier. Unfortunately, as some reviewers on Amazon point out, he gives Northern Europe the short shift. Undeniably, Northern Europe has churned out some pretty horrifying foods from semla to shortbread.
So does this whole "eat your heritage" thing just not apply to people from Northern Europe? Well, I think people just aren't going back far enough in history. Scottish Food in Season's Larder Page lists all sorts of foods that are really delicious and healthy. Venison, edible seaweed, shallots, kale, plums, tayberries, barley...doesn't sound bad to me. Actually, it sounds very close to the diet that I've found is best for me. Just avoid the prepared foods, which are a relatively recent invention, and the Scottish diet is just as admirable as the traditional Pima diet that Nabhan praises.
Now that offal is trendy, maybe I'll even start eating haggis.
