Food photography takes a lot of nuanced artistry and technical know-how to make the product look delectable and appetizing, and because of that, you might decide that taking more control with artificial light is the way to go. This great video will tell you what you need to know when purchasing lights for food photography.
Coming to you from The Bite Shot, this helpful video will guide you through some of the things to think about when you're considering purchasing an artificial light for food photography work. Although food photography is frequently done with natural light, you might find that the control and freedom (particularly with when you shoot) you gain from an artificial source is worth the investment. As the video mentions, you can get quite a bit done with just a speedlight, and if you're a beginner, I recommend starting there. I personally love the Yongnuo YN600EX-RT II; I bought four for the price of one of my more expensive speedlights, and when you include the wireless transmitter, you have a complete wireless flash system for under $200. I'm not anywhere near as afraid to break one of them as I am the Canon version. Check out the video above for everything you need to know.
