During 2004 to 2008, I lived in Taipei, renting a room, one side wall of which was made of seasand.

The Chinese medicine doctor felt my pulse and immediately asked me if there was a huge water case beside my bed.

There are many cold food or drink, for example, ice cream, and Chinese medicine doctors suggest that we should avoid all cold food or there will be water stoped in our body, some kind like that.

In some countries there are dishes that have to be cooled. But I guess no human being would prefer eating cool food on a regular basis.

Thanks for your different opinions.

I've never heard that cold food could be harmful. Your body does use some energy to heat the food up as it digests it, but certainly no more than it would on a cold day.
