Protein 101: The Basics & Beyond.
Are you looking to improve your fitness and overall health? if
so, protein is a nutrient you won’t want to overlook. As one of the building
blocks of muscle tissue, protein plays a crucial role in exercise recovery and
muscle growth.
In this blog,
we will explain protein in as simple way as possible to make you understand it
better. From the importance of protein in daily life to the types of amino
acids in a protein.
So without
wasting any time let’s dive into it.
What is Protein?
Protein is a macronutrient hat is essential for the growth, repair, and maintenance of cells in the body. It is composed of long chains of amino acids, which are the building blocks of protein.
There are 20 different amino acids that can be combined in various ways to create different types of protein. Some amino acids are considered “essential,” meaning they cannot be produced by the body and must be obtained through the diet. Once consumed, proteins are broken down into their component amino acids and used by the body for a variety of functions, including the production of enzymes, hormones, and antibodies.
Protein is found in a variety of foods, including meat, fish, poultry, dairy products, legumes, and grains.
Importance of Protein in Daily Life.
Protein is a necessary nutrient that has a variety of significant functions in our everyday lives. Following are some of the main arguments in favour of protein:
• Developing and Maintaining Tissues:
Our muscles, bones, skin, and other tissues all depend on protein. It is crucial for creating and healing these tissues, particularly following exercise or an injury.
•Enzymes and Hormones:
Many enzymes and hormones in the body are made of protein. These substances regulate many of our bodily processes, including digestion, metabolism, and growth.
•Immune Function:
Antibodies, which are proteins, are a key part of our immune system. They help to identify and neutralize harmful pathogens and protect us from disease.
•Energy and Satiety:
Protein is a source of energy for the body, and it can also help to promote feelings of fullness and satiety. This can be helpful for weight management and reducing cravings.
•Brain Function:
Some amino acids, which are the building blocks of protein, are important for brain function and mood regulation. For example, tryptophan is used to make serotonin, a neurotransmitter that helps to regulate mood and sleep.
•Aging and Disease Prevention:
Our bodies gradually lose muscular mass and function as we get older. Consuming adequate protein can help to slow this process and protect against age-related diseases such as osteoporosis and sarcopenia.
How Protein Helps in Muscle Building.
Protein plays a crucial role
in building muscle through a process called muscle protein synthesis. When you
engage in strength training or other forms of exercise that cause muscle
damage, your body responds by increasing muscle protein synthesis to repair and
rebuild the damaged tissue. This process requires an adequate supply of amino
acids, which are the building blocks of protein.
When you consume protein, the
amino acids are broken down and absorbed into the bloodstream. From there, they
are transported to the muscles and used to support muscle protein synthesis.
Specifically, the amino acid leucine has been shown to be particularly
important in promoting muscle protein synthesis.
Research has shown that
consuming adequate amounts of high-quality protein, especially in combination
with resistance exercise, can help to increase muscle mass and strength.
However, it’s important to note that protein is just one of many factors that
contribute to muscle growth. Other factors include adequate calorie intake,
sufficient rest and recovery, and consistent training.
Types of Amino Acids.
Twenty distinct kinds of amino
acids are typically present in proteins. These amino acids can be separated
into essential and non-essential groups. While non-essential amino acids may be
produced by the body, essential amino acids cannot, and must thus be received
from nutrition.
What are Essential Amino Acids.
There are nine essential amino acids that cannot be synthesized by the body and must be obtained through the diet. Each essential amino acid plays a specific role in the body. Here are some functions of the essential amino acids:
1. Histidine:
Essential for growth and repair of tissues, and for the production of red and white blood cells.
2. Isoleucine:
Involved in muscle metabolism and immune function.
3. Leucine:
Essential for repairing and growing muscles as well as for generating energy.
4. Lysine:
Essential for growth and repair of tissues, and for the production of enzymes, hormones, and antibodies.
5. Methionine:
Important for metabolism and detoxification, and for the production of cartilage and other connective tissues.
6. Phenylalanine:
Important for the production of neurotransmitters and hormones.
7. Threonine:
Involved in the immune system and in the synthesis of proteins and glycine.
8. Tryptophan:
Important for the production of serotonin and melatonin, which regulate mood and sleep.
9. Valine:
Involved in muscle metabolism, tissue repair, and the regulation of blood sugar levels.
What are Non-Essential Amino Acids.
There are eleven non-essential amino acids that can be synthesized by the body. Even been produced by the body these non-essential amino acids plays important role in our body. Here are some of the functions of non-essential amino acids:
1. Alanine:
Important for energy production and the regulation of blood sugar levels.
2. Arginine:
Important for immune function, wound healing, and the production of hormones and enzymes.
3. Asparagine:
Important for the synthesis of proteins and nucleotides, and for the regulation of the nervous system.
4. Aspartic acid:
Important for the synthesis of other amino acids and for the production of neurotransmitters.
5. Cysteine:
Important for the synthesis of proteins and enzymes, and for the regulation of the immune system.
6. Glutamic acid:
Important for the synthesis of proteins and other amino acids, and for the regulation of the nervous system.
7. Glutamine:
Important for immune function, gut health, and the synthesis of proteins and nucleotides.
8. Glycine:
Important for the synthesis of proteins and enzymes, and for the regulation of the nervous system.
9. Proline:
Important for the synthesis of collagen and other connective tissues, and for the regulation of the immune system.
10. Serine:
Important for the synthesis of proteins and nucleotides, and for the regulation of the immune system.
11. Tyrosine:
Important for the production of neurotransmitters and hormones, and for the regulation of the immune system.
Food containing all the Essential Amino Acids.
Complete proteins are described as having all nine necessary amino acids. Animal-based foods such as meat, fish, poultry, eggs, and dairy are all considered complete proteins.
Animal based food source –
Beef:
A solid source of protein that has all nine necessary amino acids is beef. A 3-ounce (85-gram) serving of beef contains approximately 22 grams of protein.
Chicken:
Chicken is also a complete protein source, with all essential amino acids. A 3-ounce (85-gram) serving of chicken breast contains approximately 26 grams of protein.
Fish:
Most types of fish are complete proteins, including salmon, tuna, and tilapia. A 3-ounce (85-gram) serving of salmon contains approximately 22 grams of protein.
Eggs:
Eggs are a complete protein source, with all essential amino acids. Around 6 grammes of protein are included in one whole egg.
It’s worth noting that the protein content in animal-based foods can vary depending on the cut, preparation method, and serving size. Additionally, consuming high amounts of animal-based protein has been linked to an increased risk of certain health conditions such as heart disease and some types of cancer. Therefore, it’s important to consume protein from a variety of sources, including plant-based sources, and to not exceed your daily protein needs.
Plant based food source –
Quinoa:
A grain-like seed that contains all essential amino acids, as well as fiber, iron, and magnesium.
Buckwheat:
A grain that is free of gluten, rich in protein, and full with all nine essential amino acids.

Daily Protein Consumption.
The daily protein requirement varies depending on age, gender, and physical activity level. Here are some general guidelines for daily protein consumption:
Bodybuilding
The International Society of Sports Nutrition recommends that athletes and bodybuilders consume between 1.4-2.0 grams of protein per kilogram of body weight per day. So, for example, if you weigh 80 kg (176 lbs), you would need to consume between 112-160 grams of protein per day.
Some bodybuilders may require even higher protein intakes, depending on their training goals and individual needs. For example, bodybuilders who are trying to build muscle mass may need to consume closer to 2.2 grams of protein per kilogram of body weight per day.
Athletes
In order to assist muscle development and repair, athletes may need extra protein. The International
Society of Sports Nutrition recommends that athletes consume 1.4-2.0 grams of protein per kilogram of body weight per day. However, individual protein needs may vary depending on the type and intensity of exercise, as well as other factors such as age and body composition.
It’s important to note that these are general guidelines, and individual protein needs may vary depending on factors such as body weight, muscle mass, and physical activity level. A certified dietician or healthcare expert should always be consulted to assess your individual protein requirements.
Adult Males and Females
The Recommended Dietary Allowance (RDA) for protein is 0.8 grams of protein per kilogram of body weight per day for adult men and women. For example, a 68 kg (150 lb) adult would require about 55 grams of protein per day. However, individuals who are very active or have certain medical conditions may require more protein.
Small Children
The protein requirements for children depend on their age and weight. Generally, young children require more protein per unit of body weight than adults do. Here are some guidelines for daily protein intake for children:
· 1-4 years: 14-21 grams of protein per day.
· 5-9 years: 22-35 grams of protein per day.
· 10-14 years: 36-48 grams of protein per day.
Aged Person
As we age, our protein needs may increase due to a decrease in muscle mass and changes in protein
metabolism. The RDA for protein for adults over 65 is the same as for younger adults (0.8 grams of protein per kilogram of body weight per day), but some studies suggest that higher protein intake may be beneficial for older adults.
