Category: Nutrient classification

According to research, while many nutrients are vital to our diet, the human body is capable of synthesizing a number of compounds on its own. This natural ability is key to understanding **which nutrient is considered non-essential**, distinguishing them from those we must obtain directly from food for our survival and health.

According to research published in the *Journal of Clinical Investigation*, nutritional deficiencies can be categorized as Type I or Type II based on the body's physiological responses. This classification is crucial for understanding **what is a type 2 nutrient**, which can cause growth failure and weight loss rather than specific, obvious symptoms.
