Hey guys. I want to ask about spicy foods and tolerance to them. I haven't been able to find anything that describes exactly how tolerance to spicy foods work. I've read all about how and why capsaicin produces the burning sensation it does however. Is it something physical that the body does which develops a tolerance to the irritation of the spicy foods, or is it merely a conditioning fact that people are able to tolerate the same level of pain? I've never been able to tolerate spicy food very well, and so as a result have typically not enjoyed them. I have found some to have a really agreeable flavor though and I want to be able to pursue the enjoyment of these foods, but in order to do so, I will have to develop a tolerance. So right now I'm starting with jalapeño peppers. Pretty mild really, but it seems to be one of the most common spice used in spicy foods, at least here in the states. And lastly, how developed is your tolerance to spicy foods? What's the spiciest type of pepper you can consume without experiencing too much issue? EDIT: I also wonder if developing a tolerance will prevent me from feeling sick to my stomach after consuming a certain type of spice that I have yet to identify. I don't know what type of spice it is, but after consuming it, I feel quite ill, as a result of the spice. Not even so much the heat, just a general feeling of not being well.
