We often hear of various segments of society being provided with hot meals, as if this provision fulfilled an essential need. I can see there may be a psychological element, but is there any physiological advantage to a HOT meal?
This one has always bugged me..my ex mother in law always used to go on about having one hot meal a day, and went mental at me if I offered a cold salad for dinner!
Sorry I can't answer your question..hoping someone out there can help us both :o)
