What is described as often being the most significant nutritional variation when comparing mature white bell peppers to bright orange and red varieties?

Answer

The difference in carotenoid levels.

When nutritionally contrasting the different mature colors of bell peppers, the key difference often lies in the concentration of specific pigments derived from carotenoids. While all varieties retain benefits like Vitamin C, the bright orange and red peppers are known for having high levels of carotenoids, such as beta-carotene, which acts as a precursor to Vitamin A. The white variety, having not developed these intense pigmentations, naturally contains lower levels of these specific carotenoids, making this difference in pigment precursor concentration the most notable nutritional variation between the mature colors.
