Hello there!

As you may know, there are two main types of carbohydrates:

  • Simple
  • Complex

Some examples of complex carbohydrates include potatoes, split peas, pinto beans, asparagus, and practically anything that is low in sugar and high in fiber.

Simple carbohydrates, for the most part, are the complete opposite. When you're eating a sugar cookie or drinking processed juice, you are basically consuming simple carbohydrates.

With this said, the answer to your question is simple carbohydrates.

I hope I helped!

Remember, anything sweet is simple. :)
