In this article, I would like to touch upon a field that is one of the most popular ones in the fitness industry. This post focuses on a macronutrient that enjoys a celebrity status in the fitness world and has absolutely enjoyed the spotlight for a considerably long time. Yes, I am talking about “Protein”
Protein
Resort
The word protein is derived from the Greek word “proteios” which means “primary” or “of prime importance”. The name clearly shows how important this macronutrient is for us.
Proteins are essentially bio-molecules that are made up of smaller units called “amino acids” that are associated together to form polypeptide chains.
Protein is gift in our skin, hair, callus, cartilage, muscles, tendons and ligaments.
Proteins hold together, protect and supply a definitive structure to the body.
From the perspective of condition and fitness, there are things about protein that are important for us to understand.
i) Functions
ii) Amino acids
iii) Sources of protein
iv) How much protein to consume?
v) Negative effects of piquant too much protein
i)Functions:
Protein being a macronutrient is a source of vigor for the body. In case one’s carbohydrate intake is not sufficient, the body resorts to protein to supply vigor to the body. However, this is not the prime function of protein. The primary functions of proteins are:
Growth
Tissue repair
Immune law function
Hormone and Enzyme production
Lean muscle mass and tone maintenance
Regulation of metabolism
Maintaining acid balance in body
Since proteins sustain all these functions, they are called the “building blocks” of our body.
ii)Amino acids:
Just as Proteins are the construction blocks of our body, amino acids are the “building blocks of protein”.
Amino acids are the structural units that make up proteins. There are 20 natural amino acids that constitute discrete types of protein in different ratios.
Amino acids are classified into two types:
a)Essential amino acids
b)Non-essential amino acids
This classification does not reflect the point of the amino acids belonging to each.
Essential amino acids are those that cannot be synthesized by the human body and therefore must be obtained from food
Non-essential amino acids are those that can be synthesized by the human body.
The list of valuable and non-essential amino acids are given below:
Essential:
Isoleucine
Leucine
Valine
Lysine
Tryptophan
Methionine
Phenylalanine
Threonine
Non-essential:
Alanine
Asparagine
Glycine
Aspartic acid
Proline
Cysteine
Glutamine
Glutamic acid
Selenocysteine
Histidine
Taurine
Tyrosine
Arginine
Serine
Ornithine
It is crucial for the body to get enough amounts of each of these amino acids in order for it to function properly.
iii) Sources of protein:
Foods that consist of each and every one of the aforementioned valuable amino acids are called complete sources of protein.
Foods that lack one or more valuable amino acids are called incomplete sources of protein.
This is the singular most distinguishing factor in the middle of vegetarian and non-vegetarian sources of protein.
All meat and other animal products are sources of complete protein.
For example:
chicken, beef, lamb, pork
poultry, eggs
fish, shellfish
milk and milk products
Vegetarian sources:
Nuts
Soy foods (not recommended as they are toxic and yield estrogen in the body)
Sprouted seeds (each type of sprout differs in nutrient proportions, so eat a variety)
Grains (especially amaranth and quinoa, top in protein)
Beans and legumes (especially when eaten raw)
All vegetarian sources of protein are incomplete (except for soyabean) and also have less quantity of protein.
This is the prime reason, vegetarians find it difficult to derive their daily protein needs. However, this doesn’t mean that vegetarians cannot build muscle. They merely have to concentrate discrete sources to derive a similar amino acid profile as non-vegetarians do.
Vegetarians are made to believe that it is virtually impossible for them to build ability muscle if they do not consume meat. I do admit, the journey for a vegetarian is much more difficult than for a non-vegetarian but it is admittedly not impossible.
This should come as a relief to many of you out there who are vegetarians.
iv)How much protein?:
If you type the question “How much protein is required?” (or any other divergence that means the same thing) you will get 98,700,000 results.
This just goes to show how popular this question is.
Of procedure it is.
In the last 5-10 years, the protein craze has absolutely engraved into the minds of just about everybody in the civilized world.
Not only athletes and bodybuilders, but even the couch potato who has never idea once about nourishment knows all too well about protein and how he needs lot of it.
The fitness business has never for once promoted anyone as much as protein. I mean, if you ever ask the guy in the gym who has huge muscles what his secret is, he is absolutely going to say “Tons And Tons Of Protein!”
And the internet just makes it worse.
Bodybuilders, fitness models, athletes, coaches, adolescent guys who just started working out and even that fat guy eating McDonalds everyday preach as if they speak the word of the lord – “1 gram protein per pound bodyweight”. That phrase itself has 2,650,000 hits in Google search!
To make it worse, Supplement companies. There is no bound to the limits they will push a product, followed by a shot of a beefed up guy keeping that whey protein supplement.
What does this do for midpoint guys like you and me?
No good to say the least.
All this misinformation is misleading all of us into reasoning that we need to ensue what is mindlessly preached.
So I will take this opportunity to address the question of “How much protein is required?” in a holistic and realistic sense.
Let me begin by first stating that the nourishment itself works on a “Supply And Demand” basis. What this means is that, what we need and how much we need depends on the demands that our body has. Demands that are considered by our workouts, our daily program and other small factors in our day-to-day life. So, the claim that we all need one gram of protein per pound bodyweight Way off track.
The daily protein requirements of an private depend upon the intensity of rehearsal they perform. While rehearsal is considered a relatively small source of vigor while rehearsal when a balanced diet is consumed, research has shown that the greater the intensity of rehearsal the greater the loss of protein in the urine. So essentially, the greater your workout intensity, the greater your protein needs.
For an midpoint adult who performs minute to no rehearsal in the day, the Rda recommends piquant 0.8 – 1.0 grams per kg bodyweight. This is much lower than 1.0 gram per pound hint made by fitness professionals and is appropriate. Because it is just about enough to meet the needs of this singular person.
Athletes on the other hand have higher requirements.
Athletes involved in vigor and power type sports like bodybuilding, powerlifting, football or sprinting have even higher dietary protein needs than the durability athlete to avow a safe bet nitrogen balance. 1.25 g per kg per day was recommended as the appropriate Rda for vigor and power athletes by Lemon et al (1992) and Tarnopolsky. [1]
And its not just the bodybuilders or the vigor athletes.
Research indicates that the protein needs of a long length runner may admittedly be more than vigor athletes and bodybuilders to avow safe bet nitrogen balance. This is because durability athletes excreted more daily urea and therefore suffered greater loss of protein. Lemon et al. (1991) and Dohm (1985) advise that athletes who engaged in durability type activities consume almost 1.5 g per kg per day to avow safe bet nitrogen balance. [2]
All of this is in terms of maintaining a safe bet nitrogen balance i. E production sure protein catabolism does not place and therefore maintaining lean muscle mass.
But how much protein do we need to build muscle?
Now if you are a extremely active man who works out intensely in the gym, then you would do well with 2.4 g per kg is more than enough to help you gain muscle.
A thoroughly wrong idea is equating the rate of muscle growth to the estimate of protein consumed. There is no research that proves that higher intakes of more than 2. 4 g/kg/d admittedly were responsible for improving muscle mass while resistance training.
So please don’t assume stuffing down tons of protein is going to help you put on muscle any faster.
Remember, More Protein Is Not Equal To More Muscle
Keeping aside all this science and research, what you need to understand is that your daily protein needs are not set in stone and depend almost entirely on you and your performance level.
So do not get caught up in generic information.
To plainly list it down,
Average adult ==> 0.8 – 1.0 g per kg weight per day
Endurance athlete ==> 1.5 g per kg weight per day
Bodybuilders and vigor athletes (muscle maintenance) ==> 1.25 g per kg weight per day
Bodybuilders and vigor athletes (muscle gain) ==> 1.9 – 2.4 g per kg weight per day
Remember, protein requirement or nourishment in general works on a “Supply And Demand” basis. So don’t go about supplying if there is no need.
Moving on we shall go to the last part which is: “Negative effects of too much protein”
iv)Negative effects of too much protein:
Now, the intuit why I chose to address this topic is because a lot of citizen who are opposed to the bodybuilding diet keep talking about how protein affects the body negatively.
One of the most notable myths concerning this is the whole “Protein damages kidneys” nonsense.
So I found it valuable to talk about this and clear the air once and for all.
Kidneys are involved in extraction of urea. The only study to have ever shown that high protein diets sway the kidney function was done by Brenner et al. (1982). However, these studies were done on patients that already had irregularly functioning kidneys. Therefore, it can not be assumed that citizen with a general kidney function will ever have kidney disease or malfunction due to high intakes of dietary protein. Currently, there is no evidence to show that protein intakes in the of 1.76 g/kg/d would conduce to any condition problems (Skov Ar, 1999). [3]
That being said, lets look into the potential negative effects of piquant high dietary protein:
1)Individuals with liver or kidney problems can be susceptible to adverse reactions due to excess protein. Since the Liver is the major organ involved in protein metabolism and kidney in the excretion of ketones and urea, excessive protein may cause stress in these organs for those citizen who already have a disorder in them.
2)Consumption of protein is usually accompanied by consumption of saturated fats and cholesterol. excessive intakes may mean high levels of saturated fats and cholesterol as well, However, this can be avoided admittedly by selecting lean cuts of meat and by removing the fat around the meat before cooking.
3)High protein diet has a diuretic ensue and due to excessive production of ketones and urea, frequent excretion is valuable to take off these byproducts from the blood (William, 1999). [4]
As a result, dehydration may occur quickly. Athletes who consume high protein and rehearsal in hot climates have therefore a greater susceptibility to dehydration. However, this issue can also be avoided by enough and frequent intake of water.
4)Last but not least, excessive consumption of protein can also lead to fat deposition. Protein is a macronutrient at the end of the day and can be used for vigor and/or stored as body fat when consumed in excess. So don’t overdo the protein to speed up your results. You may just go in the opposite direction.
There you go. My unabridged description on Protein.
I hope that you have taken the time to read straight through the whole article.
This is one area that causes a lot of obscuring in citizen with respect to their diet and is therefore valuable to thoroughly understand.
I assure you, that once you have read and interpreted this article, you will not need to quest the internet for data on protein ever again.
Until next time.
