Glucose.
Fiber is classified as a "non-essential substance" thus far, as most dietary fiber is not absorbed by the digestive tract. It is not classifed under any nutrient. It does however, aid in absorbing and digesting other substances.Debates are ongoing as to whether or not fiber should be classified as a nutrient in and of itself. Perhaps one day, it will be, but it is unlikely.
Fiber is made of glucose molecules arranged into a starch(cellulose), so they are not a quick source of energy. Humans have difficulty digesting fiber.
The nutrient made of starch, sucrose, and fiber is carbohydrates. Carbohydrates are a major source of energy for the body and can be categorized into simple carbohydrates (like sucrose) and complex carbohydrates (like starch and fiber). While starch and sucrose provide readily available energy, fiber plays a crucial role in digestive health and regulation.
Fiber
Carbohydrates like sugar, bread, and fiber. Fat also provides energy but I would not consider it to be basic.
