If you take in more than that you risk digestive issues on longer rides. The harder you push your limits the more this is true. If you are just cruising, it doesn't matter as much. Everyone is a little different but the above guidelines should work. If I start a century with a good solid meal I'm usually good for about 30- 70 miles depending on the difficulty of the ride before I have to start eating. The key is to start eating and drinking before you get hungry or thirsty.
By your definition what ever it may be Cliff bars are not food either. Yeah whatever. Gels are nutrition as is any food you might be eating on your ride. It is not the distance that matters as much as how long it takes you to go that distance. I eat sometimes as little as 100 calories and hour after the first hour and do fine. I've used cereal bars, fig bars, Cliff bars, fruit, and a bunch of other items including gels on rides. I use gels for quick pick-me-ups like right before a climb but I do factor them into my 100 - 250 calorie an hour plan after the first hour. I do not factor in calories from beverages such as Nuun or Gatorade.
