Which of the following is an example of complex carbohydrates?

Complex carbohydrates are made up of longer chains of sugar molecules and typically provide more lasting energy compared to simple carbohydrates. They are often found in whole, unprocessed foods and are beneficial for overall health because they usually contain fiber, vitamins, and minerals.

Whole grain breads are an excellent example of complex carbohydrates. They are made from grains that have not been refined, allowing them to retain their bran, germ, and endosperm. This means they have more nutrients and fiber, which can aid in digestion and help regulate blood sugar levels.

In contrast, syrups, cakes, and jellies are primarily composed of simple sugars and often lack the fiber and nutrients found in complex carbohydrates. These options are processed and tend to digest more quickly, leading to rapid spikes in blood sugar. Therefore, whole grain breads stand out as a healthful source of complex carbohydrates in this context.
