Chicken can be deadly if it is heated for the second time. You may experience some digestive problems as the proteins change their structure on reheating. Chicken contains more proteins than the red meat; hence it is preferable to eat cold chicken than a reheated one. If you still want to eat it warm, then be sure that the temperature is low and that the warming process lasts longer.

You should certainly think twice before you start warming up some of these foods. Unless you want to deal with potential health problems, it is always better to avoid reheating food.
