Whether you get that through a higher daily intake of carbs, or by

Fruits and vegetables ARE composed of carbohydrates primarily.  Not sure if
this statement was a mistake or you intended to mean foods like pasta,
grains, and processed sugars.

In any case, as has been stated several times previously, humans can survive
very well on very low carbohydrate diets.  However, a primary reason to eat
vegetables and fruits in optimizing one's diet (aide from the need to
acquire calories beyond protein and fat requirements) is to obtain
antioxidant nutrients, minerals, and fiber.
