The least important role of nutrition in wellness is learning to eat a high fiber diet.

Explanation:

A diet naturally high in fiber includes whole grains, fruits, and vegetables and is low in fat and high in alternative nutrients. High fiber diet is the least important role because overwhelming an excessive amount of fiber causes inauspicious effects like cramping, constipation or dehydration.
