Your text conveys the general idea well, but it could be polished for clarity and flow. Here’s a revised version:
"Food vlogs? Food content? Should I include them? Well, it's a little bit of everything."
This version corrects "contents" to "content" (as it is generally used as an uncountable noun in this context) and changes "it" to "them" for grammatical consistency with "food vlogs" and "food content."
