This question may seem funny, but I think biology must have good answers. I think no more explanation is needed. I really thought about this and searched for an answer, but there is nothing yet. If you know some thing about or have some thing which may lead to good answer(s) please express. Also, do animals portray the same behavior in such situations? |

For these two phenomena to create the same feelings all of the time, the physiology that engenders these feelings would have to be the same. All I can do is point out that these have been separate and distinct even in yeast and bacteria and invoke a likelihood argument. The impulse for hunger is almost as old as living things. In bacteria, cyclic Adenosine mono phosphate (cAMP) mediates hunger, though this does not appear to be universal. Sexual reproduction appeared much later - in the single celled eukaryotes mating factors for instance are mediated by the MATa/alpha receptors. In animals like C elegans the differences persist (hunger, mating). This is not a precise argument, but there is the entropy argument - the odds of these 2 signals evolving together biochemically or genetically is quite unlikely given how separate they have always been. That's not to say that eating food can't create a sexual arousal, but it does not do so all the time. The sexual response appears to be plastic and adaptable to nearly any sort of stimulus. The fact that in primates and many other animals, the pleasure stimulus is related to both mating and eating might make them seem like similar impulses, but when you go deeper it doesn't seem plausible. So the two could hypothetically create the same feeling, but if you are asking why doesn't it usually... then there are lots of reasons why. I find it helpful to reverse the question and ask - what would happen to a species where you could suppress the mating impulse by eating? Probably not an adaptation that would survive long. |

Well, the whole point of watching porn is sexual arousal. (Or research for the curious, but that's another thing) Watching someone eat delicious-looking food CAN make people feel hungry. I admit, I have a bad tendency of feeling hungry if I see good food, or if I see someone eating good food. But I don't get the point of the question. Are you wondering if most people feel this way about watching someone eat, or are you wondering if people are AROUSED by watching someone eat? Lol. Some clarification would be useful. EDIT: Ok, I think I get it now. You're wondering why aren't there any "food scenes" for food-loving people? Well, it's not as widely prevalent as porn, but it IS there for those who are into it. Example: http://foodporndaily.com/explore/food/ ^ One of my favourite sites, actually. |
