What are simple carbohydrates?

Simple carbohydrates consist primarily of sugars that are easily and quickly digestible, providing immediate energy. They are found naturally in foods such as fruits, as well as in processed foods that contain added sugars. When consumed, these carbohydrates can rapidly increase blood sugar levels, supplying a quick burst of energy. However, they often lack significant nutritional value when they come from refined sources such as candies, sodas, and baked goods. This characteristic of providing quick energy while being less favorable in terms of nutritional density is what defines simple carbohydrates, making this answer the most accurate in identifying their nature.

In contrast, whole grains, fruits, and high-fiber foods generally offer more complex nutritional benefits, including sustained energy, vitamins, minerals, and the ability to promote satiety, which distinguishes them from the quick energy provided by simple carbohydrates.
