What is protein? Well, it’s a macronutrient that our body uses for fuel. It’s essential for building and repairing muscle, healthy cell structure, storing and transporting key nutrients, and forming vital organs, arteries, and glands throughout the body. It’s also necessary for the healing and repair of the skin, bones, and hair.

That all sounds pretty cool, but you’ve probably heard all of that before. The thing is, these amazing tiny molecules are actually much more fascinating than you might think. Here are 5 things about protein that you probably didn’t know!

◙    High protein diet will aid fat loss.

People tend to associate protein with body builders, gyms and huge muscles. However if you are aiming to lose body fat then protein will most certainly help do so! Eating a high protein diet will not only help with your appetite but it plays a big part in retaining muscle whilst trying to lose weight. The more muscle you can retain whilst trying to lose weight, the more calories your body will burn, making it a lot easier to achieve your goal.

◙    Protein is the only pragmatically essential macronutrient.

You need to eat protein on a daily basis in order for your body to get all the essential amino acids (EAAs) it requires to stay healthy.

•  Your body has large EAA requirements.

•  Your body needs different amounts of each EAA.

•  Different proteins contain different amounts of each EAA.

Even if you technically consume enough protein, these three factors combine to make it easy for you not to get enough of each EAA. Vegetarians are especially at risk, because unlike most animal-based proteins, most plant-based proteins are poor in one or more EAA.

◙    Proteins don’t live very long.

Our bodies contain around 100,000 different kinds of protein. Unfortunately, most of those proteins have a lifespan of two days or less. Since the body can’t store protein for the long term, we need to replenish the supply by consuming protein-rich foods every day.

◙    Improves Learning, Memory, and Brain Function

To keep concentration and energy levels up, the brain needs a regular supply of amino acids. Protein can help by providing the brain with these essential amino acids. To get you and your brain through those boring afternoon meetings, make sure you take a high-protein lunch. Enhance your learning, memory, and brain function with the right protein diet.

◙    Human Hair is Made Up of Protein

Hair comes in a variety of colors and textures, but it is all manufactured from the same elements. hair is made up of a protein called keratin, which has a helical shape. Sulfur bonds are found in keratin, and the more sulfur bonds it contains, the curlier a person’s hair will be.
