What is an Essential Nutrient

In answering the question what an essential nutrient is, the dictionary definition of “nutrient” is something that provides nourishment. In the field of nutrition and diet, nutrients are more specific. There are six specific categories of Essential Nutrients, all of which are necessary to sustain life, which is why we call them essential nutrients.

Importance of these Essential Nutrients

The ability to sustain life is the key to answering the question, what is an essential nutrient. In some nutrient charts, fiber is mentioned as an essential nutrient. However, you do not often find dietary fiber on most nutrients' lists. Fiber is a proper nutrient because it is absorbed and has beneficial effects on your body. If you are vegan or vegetarian, you may need additional nutrients. Read Necessary Nutrients for Vegan and Vegetarians..
