Which of the following describes the main difference between energy that comes from simple foods (such as sugar or candy) and those that are complex (such as oatmeal)? A. The body prefers simple foods because they provide more energy than complex foods. B. It takes time and energy for your body to break down more complex foods, whereas simple foods are broken down more quickly. C. Complex foods need more cooking time; therefore, they're less nutritious than simple foods. D. Simple foods are less harsh on the digestive system; therefore, simple foods are easier to digest.

B. It takes time and energy for your body to break down more complex foods, whereas simple foods are broken down more quickly.

When we talk about simple and complex foods, we are often referring to the types of carbohydrates found in those foods. Simple carbohydrates, such as those found in sugar or candy, are composed of one or two sugar molecules. They are quickly absorbed by the body, providing a rapid source of energy. This can lead to a quick spike in blood sugar levels followed by a rapid decrease, which is why after consuming simple sugars, you might experience an energy rush followed by a crash.

Complex carbohydrates are found in foods such as oatmeal, whole grains, legumes, and vegetables. These are comprised of longer chains of sugar molecules, which take longer for the body to break down and convert into glucose (the form of sugar used by cells for energy). As a result, complex carbohydrates provide a more gradual release of energy and can help maintain more stable blood sugar levels. They also tend to be higher in dietary fiber, which slows digestion and provides various health benefits, including improved gastrointestinal health and a feeling of fullness, which can aid in weight management.
