Protein – Health Benefits, Deficiency and 22 Food Source Of Protein


Except for water, proteins are the most abundant substances found in our body. They are involved in nearly every task. We need protein to repair and maintain body tissues such as skin, hair, muscles, eyes, and organs. Moreover, they are needed to transport and store molecules such as oxygen, iron, and hemoglobin. Next to carbs, it’s a major source of energy and it is needed to regulate and create hormones and enzymes, too.

What Is Protein?

Protein is a molecule that is made up of amino acids. Twenty different types of amino acids exist to make up many different structures of protein in the form of chains. Since some of these amino acids cannot be made by your body, they are considered to be essential amino acids. Protein from animal foods is considered complete proteins because they contain all of the essential amino acids needed by your body. Protein from plant sources is incomplete, meaning that these foods only contain some of the essential amino acids that your body needs.

Health Benefits Of Proteins

Signs Of Protein Deficiency

1.You Cannot Concentrate

As a matter of fact, you need to keep your blood levels steady so you can stay focused. Without protein, your blood sugar levels go up and down constantly. Moreover, you will find it hard to concentrate on anything.

Your brain needs a stable stream of carbohydrates so it can work efficiently. Eating adequate protein facilitates the time-release of carbohydrates so that you do not run out. Without protein to do this function, you will simply have fleeting blasts of mental energy. When the bursts pass on, your brain has a tough time staying alert.

2.Constant Food Cravings

You might assume a protein shortage would create a hankering for a hamburger or T-bone steak. Experts, however, have found that without the protein necessary to steady your blood sugar, your body instead looks for a more immediate solution. Translation: craving candy and other junk food to fill the gaps.

3.Muscle And Joint Pain

Protein is critical for building and rebuilding muscle tissue, so it makes sense that a deficiency would cause muscle pain. A research has shown that protein also plays a pivotal role in the synovial fluid that surrounds joints, preventing them from wear and tear. When dietary protein is lacking, the body pulls from its reserves in both the muscles and joints. As a result, muscles tighten and ache, and joints stiffen.

4.Thin Hair And Nails

Sure, many factors (including genetics) play into thinning hair, especially as we age. But regardless of your DNA, hair and nails are made up almost entirely of protein and are strong indicators for even the slightest deficiency. Hair prone to splitting or breaking and brittle or ridged nails can indicate a lack of protein in your diet.

5.Poor Bone Health

How much protein you get, or don’t get, also affects your body’s calcium levels. If you’re consuming a diet too low in protein, that can negatively impact the ability of your digestive tract to absorb this mineral, which results in a higher excretion of it into your urine. The net effect is that too little calcium is taken up by the body, which means it may look to your skeletal system as a backup source since the cells must have a critical level of calcium for proper functioning.

6.Edema (swelling)

Protein plays an integral role in keeping excess fluids from accumulating in tissues as blood travels through the body. Research has shown that when protein levels are insufficient, fluid tends to build up in tissue. Its most notable in hands, feet, ankles, and cheeks.

7.Frequent Illnesses

Are you otherwise in good health but find yourself using all your sick days every year? More protein could be your best prescription. Protein is key to a strong immune system. It’s the foundation of red blood cells, white blood cells, and antibodies. All of these work together to fend off bacteria, viruses, and other pathogens in your body.

8.You Lose Muscle Tone And Strength

You need protein to build and maintain strong muscles. If you do not get enough protein, you lose muscle tone and strength. Moreover, your joints become stiff and your muscles, tight and sore. Further, you tend to feel weak. You may not be able to perform your workout and exercise routines with your usual form and power.

9.You Are Moody

Protein stabilizes your blood sugar. Without it, you are likely to go through a roller coaster of highs and lows in energy and mood. You find it tough to handle stress calmly. Moreover, you also find it difficult to sleep.

The Recommended Dietary Protein Intake Is as Follows

  • For men: 55.5g to 56.5g daily
  • For women: 45.5g to 46.5g daily
  • For endurance athletes: 1.2g to 1.4g per kg body weight daily

Types of Protein

There are two basic types of protein: complete and incomplete.
