In the North and in Europe hot bread is considered unhealthy.
This is probably another fussy superstition, like the European superstition that ice-water is unhealthy.

Europe does not need ice-water, and does not drink it; and yet, notwithstanding this, its word for it is better than ours, because it describes it, whereas ours doesn't.

Europe calls it "iced" water.

Our word describes water made from melted ice--a drink which we have but little acquaintance with.
It seem a pity that the world should throw away so many good things merely because they are unwholesome.

I doubt if God has given us any refreshment which, taken in moderation, is unwholesome, except microbes.
Yet there are people who strictly deprive themselves of each and every eatable, drinkable and smokable which has in any way acquired a shady reputation.
