What are complex carbohydrates-?

Complex carbohydrates are typically long, multiple-branched chains of sugar units. Complex carbohydrates generally take longer to digest and absorb, because their sugar units first must be separated from the chain. Starch that has been processed into fine particles, such as flour, is much more quickly absorbable than unprocessed foods. Fiber is a complex carbohydrate that accounts for less than the four Calories per gram of other carbohydrates.

Granola bars, carrots, Apples,and any fruit or vegetable contain complex carbohydrates.
