More about the early and very rapid spread of capsicum peppers in the Old World than I've ever seen in one place before.
I also didn't know they were such a nutritional boon. It appears one reason they became so entrenched is they're a good source of Vitamin C in peasant cuisines centered around a starch like rice. My thought is that moderns may tend to miss this point because we have so much better access to citrus fruits and other very high-quality C sources.
The bit about paprika having been introduced to Hungary by the Ottomans was also particularly interesting to me. This was less than 30 years after they had reached the Old World.
