So, apparently, capsaicin inhibits collagen fiber formation, but it improves the fibers at the same time. This could be very interesting information for those with Ehlers-Danlos syndrome (some people who have some symptoms but lack others might benefit from capsaicin, and some people should probably avoid it):
Anyway, a sibling's child got diagnosed with it, and my sibling thinks I might have it, too. So, that's why the interest in researching collagen all of the sudden. I looked up capsaicin and collagen to see if there was a connection, since eyes are supposed to be high in collagen, and as of this year, capsaicin (when I consume chile peppers) has mysteriously been increasing my existing sensitivity to ultraviolet radiation. The increase in ultraviolet-sensitivity lasts about a day (potentially longer), after exposure ceases. Note, however, that hot peppers do not increase my sensitivity to indoor lights, particularly (although celery seed, celery leaves, and bilberries do; I should research those as they pertain to collagen next).
I don't necessarily believe EHS is my most likely scenario (certainly not the most common kinds), but I do things it's likely that I have irregularities having to do with collagen.

Celery contains psoralen, which increases the skin's sensitivity to UV. I'm not sure if it increases the eye's sensitivity. Lots of things contain psoralen, so I'm not sure if it's what makes celery make me more sensitive to artificial light. Either way, if one has Ehlers-Danlos syndrome, then it's good to know about psoralen, since UV exposure is a concern for Ehlers-Danlos syndrome.
Figs are said to be high in psoralen. I wonder if they would make me more light-sensitive. I'm really craving some fig bars, now. I haven't had any in years, to my knowledge. Fig bars make a certain condition of mine (which involves some certain veins) more severe temporarily (for unknown reasons); so, that's why I don't eat fig bars very often anymore (albeit I love them). I wish they had fig-free bars like that (even the strawberry and apple ones have figs in them, I think). How about date bars?
