janea, I am fully aware of the history of the Irish famine. While the potato crops were healthy, Irish peasants did have enough to eat and good food too, which potatoes are. That's why the potato blight was so devastating, along with bad decisions by the British government which exacerbated the problem.
Whatever the outcome of the Brexit negotiations, I doubt that anything like the privations that those people suffered nearly two centuries ago will be visited on us. Exactly. Talk about stockpiling and food shortages are ridiculous fear mongering. We have an obesity problem because food is over-abundant and we have not adapted biologically to deal with that uet, as I've said a few times on GN before.
My point was that carbs, per se, do not make you fat. Too much food does that. I also disagree with the implication in your post that filling up with bread and potatoes (or other high carb staples) is a bad thing in general. It's what human beings have done and still do ever since they invented farming.
