I would just add, that tolerance is worth developing. You get a new world of flavors open to you, but also you get this wonderfully stimulating sensation which can help you feel good, but isn't necessarily fatty or sugary.
I cook with more peppers when I feel indicators of a possible cold or flu. It seems to help. I have also read claims of it eroding arterial plaque and lowering cholesterol. Only non-suspect study a quick Goog turned up was a NIH study on lowering cholesterol on rabbits(it did!).
