[MCU]If Wakanda has been isolationist for centuries if not millennia, does that mean they've never adopted staple foods from the New World like cassava, maize, potato, or peppers, or even older imports like bananas?

Wakanda isn't THAT isolationist. Their official story is that they're a poor nation with a weak agricultural economy, and they welcome people to visit their (carefully curated) farms and villages. We also see their royalty/ambassadors/representatives regularly visit other nations on diplomatic missions of all kinds. 

Wakanda is fully aware of other foods, and they even conduct trade under the pretense of their public appearance. Many Wakandans have eaten foreign food and know about foreign media/have internet access, though they almost certainly prefer things made at home. 

They might also conduct covert trade for things people might become suspicious of poor Wakandans trying to buy. They could pose as wealthy dealers and merchants from other African nations in order to keep Wakanda stocked up on foreign luxuries they couldn't otherwise manufacture.
