Question

Complex carbohydrates, such as fruits and vegetables, are universally viewed as healthier than simple carbohydrates like sugar. Why are complex carbohydrates a better dietary choice?

Answer 1

I'm not a biologist, so I don't know the actual answer. But my best guess is that there is more in fruits and vegetables than just simple sugars or even complex carbohydrates. There are vitamins for example. Some of the vegetables have simple proteins which are much easier to break down that the complex ones found in meat. 

Answer 2

Explanation:

Complex carbohydrates like fruits, vegetables, whole grains, beans, peas etc. They contain vitamins, minerals and fibres, that's why they are the source of long lasting energy because they take long time to digest.

Complex carbohydrates are healthier than simple carbohydrates like sugar are present in fruits, table sugar, soft drinks, milk and milk products etc. They digested quickly not the long lasting as complex carbohydrates, they can easily broken down by the body.

Complex are better dietary choice because it contains more nutrients than simple carbs. They are high in fibre and digested slowly, this is the better way for weight control.
