As humans, we require a multitude of nutrients to maintain optimal health and well-being. These nutrients are the building blocks of our bodies, providing us with the energy, growth, and repair we need to function properly. Among the numerous nutrients our bodies require, there are six essential nutrients that stand out as particularly crucial. In this article, we will delve into the world of these six essential nutrients, exploring what they are, why they are important, and how we can ensure we are getting enough of them in our diets.
What are the 6 Essential Nutrients?
The six essential nutrients are:
- Carbohydrates
- Protein
- Fats
- Vitamins
