Protein is an extremely vital nutrient in the body; in fact, it is one of the most important components of every cell in the body. Described as a “macronutrient,” protein, along with carbohydrates and fats, is needed in large amounts by the body.
Micronutrients such as vitamins and minerals are only needed in small amounts. Protein, unlike carbohydrates and fats, is not stored in the body. This means that the body has no cache to draw from when it needs a new supply.
Although this does not mean that you have to consume protein constantly, what it does indicate is that the protein we eat needs to come from better food sources. Quality is just as important as quantity.
As the main foundation of your body, life without protein would not be possible. It is used to make almost every component of the body from tiny molecules to organs and huge muscles. Several studies have been done to address the ideal amount of protein the average person should eat.
