On the food topic, Tasting History with Max Miller is a favorite - it's interesting seeing him try to recreate recipes from historical primary sources and provide historical context.
Also, Adam Ragusea has some good content on food science, among his regular cooking videos.
Also on the food topic: How to Cook that with Ann Reardon is one that I like, aside from her more useful cake-related videos, she has a great series on historical recipes as well as amusing food hack debunkings.
