Can I use information (text) from websites to my mobile app/game freely?

I'm developing a game for Android about the things like Fruits and Vegetables. I got to know that I must use Open-Source or Revenue Free images to use in my game. I have found images on www.pexels.com but now I need to know if there's something like "Revenue Free" information or "Free To Use" Information? As I need to include the text about the benefits of a fruit/vegetable. Please share your knowledge.
