Generally, mankind( I believe across all cultures) prefers to eat foods that are served hot or sometimes chilled. I have the impression that it should be more natural, beneficial and tastier to eat food as it is i.e. at room temperature, as what other animals do. Our body mechanism also would work optimally, I presume at either room or body temperatures. What is your comment?
It's just below in related questions. I don't know what answers you had before but why don't you try it out, for say a year and then come back and let us know if it made any difference. I'm sure we all look forward to hearing the result.
