Protein and Its 40 Best Sources

What Is Protein?

Protein is an essential macronutrient in your body. If you think that it is only something present in a protein shake or a plate full of food, then you are mistaken.

Every living thing is made up of protein – from the simplest bacteria to the most complicated living thing alive.

It is made up of small molecules known as amino acids. There are different types of proteins consisting of different combinations of the 20 standard amino acids. This is where it gets interesting!

Protein molecules are the most complicated molecules present in any living being. Each molecule can have from 50 to 2,000 amino acids! Till date, there are almost 10,000 types of proteins that have been identified in the human cell’s genetic sequence.

Researchers believe that there might be billions of combinations on this planet, making this another human mystery that will remain unsolved for decades.

In an average human, almost 15% of the body weight is protein. It is distributed across the body in the form of skin, blood, skeletal muscle, bones and organs.

Protein is one of the three key macronutrients in our body that are required for survival. It is called a ‘macro’ nutrient because it is consumed on a daily basis in the form of pretty much every type of food that you eat. Consider this as gas or fuel for the human body but with a slight twist.

Protein cannot be stored in your body. It is continuously being used up unlike other macro- and micro-nutrients. Other nutrients easily get stored in your body and are required in a much lesser quantity compared to protein. That is why you have to consume protein through the food you eat on a daily basis.

Usage and the Role of Protein

Since we have established that protein is present in every cell and is a building block for your body, we know that it plays a role in everything that goes on in your body.

Protein transfers oxygen throughout your body through your blood. It creates chemicals like hormones and enzymes needed for regular functioning of your body including repairing and building muscles and tissue.

When we contract an infection in our body, the cells that fight the infection are also created by protein.

There are also messenger cells which are created with protein to transmit signals. Not to mention, there are transportation protein cells that carry molecules from one place to another within your body.

Consuming Protein

We all usually recommend high-protein diets for people who want to gain a lot of mass, especially bodybuilders. It works with a combination of effective exercises.

It has been proven that bodybuilders with a high intake of protein develop muscles that are retained for a longer period of time.

There are a number of advantages of maintaining a diet with moderate- or high-protein food. According to Dr Jose Antonio, Ph.D., there are very slim chances of one to actually absorb fat or carbs when their diet consists of protein.

It has been shown that high-protein foods have very small amounts of fat and carbs. Take chicken breasts as an example – they have 2-3 grams of fat in one serving of roughly 100 grams.

When you are steadfast on a high-protein diet, you will not gain more weight through foods full of fat and carbs since you won’t be able to eat them. Let us explain.

When you consume high-protein food, your appetite will diminish, you won’t feel as hungry as you used to, and therefore you won’t give into your own cravings.

Furthermore, a higher protein consumption means more calories will burn. That is because the breakdown of protein requires more energy which causes calories to burn and decreases your weight.

How Much Protein Is Required By the Human Body?

A normal human being, who goes to work, has a moderate amount of exercise or activity in their daily routine and operates at a standard rate with no heavy training, requires 1.4 gram of protein per kilogram of their body weight.

This is the recommended minimum amount for everyone, including non-active people. For a person who weighs 70 kilograms, that’s 98 grams of protein per day.

Yes, you cannot consume all that protein in one single meal, because you will only end up with stomach problems like constipation or diarrhoea.

That is why it is recommended that you distribute the total amount of protein among your meals during the day. Once you know how much protein you need to consume, you can plan your meals accordingly.

You do not need to be precise and to the dot. We all know that some meals are rich in protein whereas some are not. Therefore, you can plan beforehand and try your best to fulfil the daily requirement.

Bodybuilders and Protein

If you are an active, intense, and serious bodybuilder, then it’s important to match your intake of protein with the amount of energy you’re already burning with increased activity.

Your muscles require a lot of healing and rest. For them to do that, you must provide them with enough protein to recover and give you a lean body.

Bodybuilders require more protein. They need more because they build muscle, and protein is the best way to build muscle.

That is why nutritionists recommend that advanced bodybuilders consume 1.6-2.2 grams of protein per kilogram of their body weight.

They are told to consume that amount over 3-6 meals, so that means 0.4-0.55 grams per kilogram per meal.

They are also suggested to take some protein 1-2 hours before and after their workout.
