Soy proteins are derived from Soybeans and these proteins are made up of amino acids which are known to be the building blocks. Polypeptides bind these amino acids together. Hydrolyzed proteins are formed when these chains of amino acids are broken down into smaller fragments by reaction with water. When these Soy Proteins are completely hydrolyzed then it is known as Soy Amino Acid.
Soy Proteins For Health
Soy Proteins are naturally derived from soya beans and considered to be a nutritional powerhouse. These soy proteins are further broken down in soy amino acid which is a good source of nutrition for people who are allergic to dairy products. It contains all the essential amino acids which are required for the proper functioning of your body. Soy amino acids play an important role in muscle building. Soy foods are cholesterol-free and low in saturated fats, thus helps in maintaining a healthy heart. Soy protein supplements are considered beneficial in weight loss.
Soy Proteins For Skin
Soy Proteins are also known to be beneficial for enhancing the texture and appearance of your skin as well. The antioxidants and anti-inflammatory properties of soy proteins help to keep your skin youthful by reducing visible signs of ageing and helps to keep your skin nourished and moisturized. Due to these beneficial properties Soy extracts are used in many skincare products.
Why Soy Protein/Amino Acid Is Important For Hair Growth
Your hair is made up of keratin which is a protein. Proteins are further broken down into amino acids. For the production of keratin, your body requires 18 different types of amino acids some of which are produced by the body while the others need to be supplemented through food. Soybeans and its supplements are considered to be the richest source of soy protein. It is very important to ensure that your body has the required amount of protein as it is the amino acids, which lead to optimum production of keratin which in turn promotes hair growth. These Amino acids are organic compounds which play an important role in maintaining good hair health. Amino acids are also required in the production of red blood cells (RBC) which facilitate the supply of nutrients and oxygen to the hair follicles thereby improving your hair health and promoting its growth.
Essential Amino Acids Which Promote Hair Growth
Now you must be thinking hard that out of 18 different types of amino acids, which of the amino acids should be added in your protein-rich diet to promote hair growth. Here we are going to tell you about the top 9 amino acids which are beneficial for hair growth.
Cysteine is the topper of the chart because it stimulates the growth of new hair. Cysteine is known to exhibit powerful antioxidant properties due to which it effectively protects your hair from the damaging effect of the sun’s UV rays. Cysteine is also known to treat alopecia, a condition in which clumps of hair fall off. Moreover, Cysteine provides sulphur to the hair cells, thus promoting the growth of healthy and strong hair.
Apart from Soyabean, foods such as broccoli, wheat germ, chicken, dairy products such as milk, yoghurt and cheese are known to be a good source of cysteine.
Methionine is an essential amino acid which exhibits antioxidant properties and provides sulphur to your hair, the deficiency of which can lead to multiple hair disorders. Methionine is known to be lipotropic because it breaks down and prevents the accumulation of fat in the bloodstream, due to which Methionine helps to increase blood circulation, thereby providing nutrients to the hair follicles and the scalp. Methionine also plays an important role in the synthesis of collagen which is required for strengthening your hair shaft.
Apart from Soyabean, foods such as eggs, fish, cereal grains, sesame seeds are a good source of Methionine.
Lysine is known to promote collagen formation and helps the body to absorb calcium, thereby adding to bone strength. DHT is known to be the primary cause of androgenic alopecia and Lysine helps to inhibit 5-alpha-reductase from producing DHT out of testosterone.
Apart from Soyabean, food such as eggs, chicken, red meat, pork, fish, legumes, nuts and dairy products are good sources of Lysine.
Arginine is another big name in the list of amino acids required for hair growth. Arginine is known to be a precursor of nitric oxide which is required to facilitate blood supply to the scalp and provides immunity from diseases which are responsible for causing baldness.
Apart from Soyabean, food such as wheat germ, fish, cashews, sunflower seeds, sesame seeds, hazelnuts, coconut are rich sources of Arginine.
Glutamine is an amino acid which is produced in our body, but as we age the production of glutamine also decreases. It is formed from glutamic acid which is necessary for providing sulphur to your strands, that is required for the growth of hair.
Apart from Soyabean, food such as pork, beef, chicken, eggs, dairy products, legumes, nuts, cabbage, and spinach are a good source of Glutamine.
Tyrosine is a non-essential amino acid which is naturally produced in our body. It is responsible for the skin and hair colouration as it helps in the production of melanin. Tyrosine suppresses tension, stress and anxiety which can lead to hair loss.
Apart from Soyabean, food such as dairy products, almonds and fish are known to be a rich source of tyrosine.
Don’t get confused with Cystine and Cysteine (which has been discussed earlier) as they are 2 different amino acids. Cystine is a non-essential amino acid which aids in promoting hair growth and at the same time fights hair loss. Cystine is formed by the disulfide bonding between 2 cysteine molecules. Due to this strong bonding in cystine, it gives strength to the hair shaft.
As Cystine is created from cysteine, the dietary sources remain the same for both.
Glycine boosts the production of collagen which is eminent for hair growth. Glycine is known to be vital for the proper functioning of the digestive system and the central nervous system, thereby preventing hair loss due to nerve disorders.
Apart from Soyabean, food such as fish, meat, spinach, cabbage, beans, soybeans, bananas and dairy products are a good source of Glycine.
Proline is a nonessential amino acid which promotes collagen production, required for improving the elasticity of your strands.
Apart from Soyabean, food such as meat, eggs, dairy products, beans, legumes, spinach, broccoli, asparagus, and avocado are a rich source of proline
Out of the 18 amino acids required for the production of keratin, these are the 9 amino acids which play a crucial role in deciding your hair health. Apart from the above mentioned Soy Amino Acids, Vitamins and minerals also play a significant role in promoting hair growth.
