What is the difference between a simple and a complex carbohydrate?

Answer 1

complex carbohydrate take longer to digest and are backed with fiber,vitamins and minerals example includes vegetables,whole grain bread,brown rice,legumes and whole wheat pasta

simple carbohydrate broken down and digested very quickly ex: table suger,milk,yogurt,honey.
A simple carbohydrate is a carbohydrate that takes your body a short amount of time to digest. Like sugar. That's why if you eat a lot of sugar, you will get a "sugar high" fairly soon. Complex carbohydrates are carbohydrates that takes longer for your body to digest. Like spaghetti. These carbos don't typically give you a "sugar high" but more of a sustained type of energy.
A simple carbohydrate could be a monosacchride like glucose, which is blood sugar, or a disacchride, like table sugar. A complex carbohydrate could be something like a polysacchride, like starch, or even plant fiber.

Simple carbohydrates are sugars, while complex carbohydrates are starches and fibers.
Carbohydrates are chains of sugar molecules. Simple carbohydrates are chained only a few molecules in length. They are easily broken down into single molecules providing quick and short energy.

Complex carbohydrates are long chains. They have many sugars attached and are often folded into different shapes, normally for storage. These carbohydrates provide a slow and steady release of energy as their break-down is slower and prolonged.

To simplify: eat complex carbohydrates as they have the most nutritional value. Try to limit simple carbohydrates.

Simple carbohydrates are sugary and they make body fat if they are not burned up completely and immediately. Complex carbohydrates (such as vegtables and whole grain bread) digest slower and take longer to burn off. They tend not to make the body fat unless eaten in large quantities and not burned off.
Complex: Carbs that you get from grains. ie Pasta

Simple: Comes from sugar (pure)
