HUMAN NUTRITION

Detailed explanation-1: -As a source of energy, complex carbohydrates are the better choice. However, for overall nutrition, it is more difficult to say. Simple carbohydrates, or sugars, are made up of shorter chains of molecules and are quicker to digest than complex carbohydrates.

Detailed explanation-2: -Because complex carbohydrates are larger molecules than simple carbohydrates, they must be broken down into simple carbohydrates before they can be absorbed. Thus, they tend to provide energy to the body more slowly than simple carbohydrates but still more quickly than protein or fat.

Detailed explanation-3: -Simple carbohydrates: Various forms of sugar, such as fructose (fruit sugar) and sucrose (table sugar), are simple carbohydrates. They are small molecules, so they can be broken down and absorbed by the body quickly and are the quickest source of energy.
