TLDR: If it can be both a video and a blog, make it both by putting basic info in the video and more in-depth info in the blog, then connect the two by putting the blog post in the YouTube video description and the YouTube video in an embedded video on the blog.
The way I see it, I'd rather see a video than read an article, but if you combined the two it'd be even better. So if it's between one or the other, I'd mostly lean towards videos, even if they're short lists of fitness tips or natural beauty advice. Seeing and hearing always enhances understanding and is easier than reading, in my opinion.
Personally, though, if I saw a video on how to do a workout, it'd be cool if the video had the basic steps, but the blog had a more in-depth description of what you're supposed to be doing and feeling to know you're doing it right. And if I saw a video on health tips, it'd be nice to have an extension blog post describing more about that kind of health tip (i.e. what kind of things, foods, and workouts to combine with that type of tip, similar health tips, links to more sources explaining why the tip is important, etc.). Also, even with your recipes, you could have in your blog links to similar recipes on your channel, other foods you could combine with these recipes to make a full meal, which of your recipes go with this one, how to get any special supplies you'll need for the recipe, etc.
Mainly, combining your blogs and videos will make your videos more concise, help you clean the descriptions, and allow you to expand on what you've said in the videos without taking too much time from people who aren't quite sure they're interested yet. This way you can make the videos easier to watch, and thus, hypothetically, more people will watch them all the way through, and any lack of information will just get people interested in more information, so they'll be more likely to go to your blog for expansions on topics discussed in the videos.
But if you did this, the blog wouldn't have to only be an extension of the videos. Some videos may not need extensions, and some blog posts may not need videos. This blog and video combination style is mainly to reduce the need to decide between videos and blog posts if you have an idea that could be both. Anything else, just make it what it needs to be, whether that's a blog, video, or combination of both.
