A certain amount of fiber in foods contributes to the health of the digestive tract, but too much fiber leads to nutrient losses. This is one of the characteristics of a nutritious diet where no constituent should be provided in excess. This principle of diet planning is called:

Moderation

Explanation:

The healthy diet plan suggests that none of the nutrients in the body should be supplied in more than normal amount, as it leads to the loss of nutrients.

The moderation in the diet plan suggests that the eating should be enjoyed both physically and emotionally.

One should always think about good food and bad food and then eat. Eating anything in much amount can be bad for the body. In case of fiber it is true that taking more fibers can lead to nutrient loss.
