as title says, do i need a little of both, or does it not matter

No.. you don't need any. What do you mean by "need"? Because you can easily survive without them.

I think his refering to being healthy.

Firstly, complex is an old obsolete classification given to (as the word implies) complex structure of carbs which therefore was believed to produce less of an insulin response, which is wrong. Carbs that are complex can raise blood sugar levels rapidly. Thats why GI score were implanted (which were originally designed to help diabetics). Therefore its reasonable to say that if yoru consuming carbs it would be best if you focus on those with a low GI.

Not sure what you mean by fibrous, you mean associated fibre?
Then yes we need a minimum daily requirement.

Complex and Fibrous are the same...you probably meant Simple or Complex.

They both have 4 calories/gram. Simple Carbs have very little essential Vitamins and minerals. Ex. includes table sugar, fruit juuice, milk , yogurt, honey, molasses, maple syrup and brown sugar. They are your best choice if you need to quickly replenish your body...in cases of hypoglycemia (for Diabetics) or skipping meals and you feel like you are about to pass out, then your quick fix is simple carb or simple sugar.

Complex Carb or Fibrous Carb - Takes longer to digest and are packed with fiber, vitamins and minerals. Ex. includes vegetables, whole grain breads, oatmeal, legumes, brown rice, white pasta and the likes.

We all need carbs during strenuous activities as we burn our energy, otherwise in a heavy workout, we burn calories, then fats, once you max em' out...you'll end up using your protein which is intended for tissue repair and rebuilding.

Have fun shapin' but save the protein for rebuildin'...

Ciao,

I think he meant complex and fibrous. While both are a complex carbohydrate, their functions in the body are different. Some foods are high in starch (pasta) yet low in fiber, and some foods are high in fiber (spinach) and low in starch.

Fiber is very important and you should try for 25g/day minimum.
