Which of the following foods is an example of a complex carbohydrate?

Complex carbohydrates are made up of longer chains of sugar molecules, which means they are digested more slowly compared to simple carbohydrates. This slower digestion provides a more gradual release of glucose into the bloodstream, resulting in a more stable energy supply.

Rice is a clear example of a complex carbohydrate because it consists mainly of starch, a complex carbohydrate that provides energy as the body breaks it down into glucose. It is also rich in dietary fiber, especially in its whole grain form, which contributes to digestive health and helps maintain stable blood sugar levels.

The other food options listed don't fit the description of complex carbohydrates. Dairy products contain lactose, a simple carbohydrate. Maple syrup is primarily composed of sucrose, a simple sugar, and fruits generally contain fructose, which is also a simple carbohydrate. While some fruits do contain fiber and can have a complex structure, they are predominantly categorized as simple carbohydrates due to their high sugar content in the form of naturally occurring sugars.
