I think these articles would be hugely improved by citing of whatever sources you have for your information.
If you're writing about a chef, the first question that comes to mind is: how do you know this information? Have you researched it, or do you have unique experience that has given you insider information into these chefs?
If you've researched it, then I think it is important to cite the sources that you used to put together your article. This not only makes you look more authoritative, it's useful to readers if they want to read more, and I've found it can also dramatically improve the search ranking of a page. Google frowns upon copied content, even if it's done through original writing and original research, and if you're getting this info from other published webpages without citing them, I think this can make your page very unlikely to rank--whereas if Google can tell that you're researching a topic, citing the original sources, and then offering your own synthesis or commentary of the material, I think this makes your new page on the topic more likely to rank well in searches for the term.
I've found time and time again that pages of mine that link to relevant external sources, especially when they're the best sources I was able to find on the topic, end up ranking much better than pages that I publish that don't link to any external sites.
If you're sharing your own personal experience that gives you insider info, then I think you need to share more of your story.
Either way, I think this will convey more authority in your writing and make the reader more likely to trust you, which I think will help you get more views for your article in the long-run.
