Ice-cream sellers will agree with this one, obviously. A research conducted by Mr. Poortvliet, a Post-Doctoral Research Fellow in Neuroscience, has stated that humans are endothermic animals, meaning that we can control our body temperatures, irrespective of the weather outside. Poortvliet’s research shows that Ice Cream ends up warming the human body when eaten due to its caloric content. The initial cooling effect is rapidly replaced by heat generated by digestive processes needed to break down the calories and that leads to an increase in body temperature. The bonus? It won’t melt like it does in summers! The cold never bothered us anyway.
