Researchers mostly. They are the one currently going through stuff from the Roman Empire through the 80's to try to understand history better. You can see a thread on HN that is about what people ate in the Roman Empire https://news.ycombinator.com/item?id=27310179 https://news.ycombinator.com/item?id=27310179. I also remember a youtube channel called "Depression Cooking" where an old lady explained what they ate and how they lived during the great depression. You can argue about the value of knowing what romans or people during the great depression ate, but our society seems to value knowing the past.
