Detailed explanation-1: -Carbohydrates are made up of three components: fiber, starch, and sugar. Fiber and starch are complex carbs, while sugar is a simple carb. Depending on how much of each of these is found in a food determines its nutrient quality.

Detailed explanation-2: -Carbohydrates are sugars that come in 2 main forms – simple and complex. This is also referred to as simple sugars and starches. The difference between a simple and complex carb is in how quickly it is digested and absorbed – as well as it’s chemical structure.

Detailed explanation-3: -The majority of carbohydrates should come from complex carbohydrates (starches) and naturally occurring sugars, rather than processed or refined sugars, which do not have the vitamins, minerals, and fiber found in complex carbohydrates.

Detailed explanation-4: -It makes more sense to define complex and simple carbs this way: Complex carbs: Carbs found in whole, unprocessed foods, including fruits, vegetables, legumes and whole grains. Simple carbs: Sugars and starches that have been refined and stripped of their natural fiber and nutrients.

Detailed explanation-5: -There are two major types of carbs: simple and complex. The difference between them lies in the number of sugar molecules they contain. Simple carbs-also known as simple sugars-contain one or two sugar molecules, whereas complex carbs have three or more. A simple sugar may be a mono-or disaccharide.
