1. Why are essential proteins so important to a
healthy diet?<span>
Proteins are a “macronutrient” (just like carbohydrates and fat), which means
that your body needs a large amount of them in order to stay healthy. A healthy
diet requires a balance between the macronutrients and the “micronutrients”
(such as vitamins and minerals, which the body needs in smaller amounts). </span>

2. How does the body use protein?<span>
The body uses proteins to: create and repair tissues; build enzymes, chemicals,
and hormones; every cell in your body is in fact made up of proteins; and it is
also the building block of bones, muscles, cartilage, skin, and blood.</span>

vegetarianism which simply cuts meat and fish out of the diet. Vegans though
need to replace those nutrients from products that are organic a non-animal-derivate
such as soy, for example. </span>
