It seems that nothing is sacred these days. Not even sheep innards boiled with oatmeal. Here's William Saletan's note on the issue from Slate:
"Anti-obesity crusaders are targeting haggis, a Scottish dish made by boiling a sheep's heart, liver, lungs, and windpipe in its stomach. Scottish health officials have put it on a list of "restricted" foods for kids because it has too much salt and fat. Reactions from haggis defenders: 1) It's "all natural," unlike hot dogs. 2) First they came for the smokers; now haggis; what's next? 3) At least we'll still have haggis hurling."
