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

• A. White rice
• B. Sweet potato
• C. Table sugar
• D. Honey

Answer: (B)

Sweet potato is an example of a complex carbohydrate because it consists of long chains of sugar molecules, which take longer for the body to break down and digest. This slow digestion provides a steady release of energy over time, making complex carbohydrates an essential component of a balanced diet. Sweet potatoes, in particular, are also rich in vitamins, minerals, and fiber, which contribute to overall health.

In contrast, the other options primarily consist of simple carbohydrates or refined carbohydrates. White rice is often stripped of its nutrients and is considered a simple carbohydrate due to its quick digestion. Table sugar and honey consist primarily of simple sugars, which can lead to rapid spikes in energy followed by crashes. Therefore, sweet potato stands out as a nutritious source of complex carbohydrates that can support sustained energy levels and overall health.
