Good Carbs Vs. Bad Carbs Infographic. This photo exposes you to the different types of carbs (simple and complex) and informs you that carbs are good- if you eat the right ones! Complex carbs (ex.rice, grains, etc) are better for you because they provide energy, makes you fuller with fewer calories, theyre high in nutrients, and they boost your metabolism. The other carbs, simple carbs, do the opposite. They make you hungrier for more, have few nutrients, make you tired, etc.
