Essential Amino Acids
Essential Amino Acids is also referred to as indispensable amino acids, essential amino acids refer to a class of amino acids that the body is unable to synthesize. These amino acids are thus, acquired from the diets that we eat. There are several kinds of essential amino acids including valine, phenylalanine, isoleucine, tryptophan, lysine among others. It is important that these acids are included in the diet so that they can be received by the body for proper growth and development.
Even though they are much needed in the body, there are some types that do not necessarily have to be included in the diet like arginine, glycine, histidine, cysteine, proline, tyrosine, glutamine and serine. These types of essential amino acids are considered to be conditionally essential. The reason why they are not necessarily required to be in the diet is because they can have unpleasant impacts on some people. For instance, those who are suffering from PKU are required to only take low amounts of phenylalanine in order to avoid mental retardation.
Typically, the acids can be acquired from diets that contain meat, dairy products, cereal grains and legumes. Besides, there are also quite a number of indigenous foods that can be consumed for the essential amino acids like Mexican corn, Japanese rice, Cajun red beans, and soybeans among others. Deficiency in even just one of the nine essential amino acids can have serious health implications and also degrade the body’s protein levels. The body can be forced to dismantle protein structures and even the muscles in order to obtain the required nutrient.
The reason why humans are unable to internally produce essential amino acids is because we lack all the enzymes that are required for their biosynthesis. It should be noted that of all the essential amino acids, there is one that is only required by children. Arginine is the essential amino acid that is not needed by adults. It is obtained from proteins and works by producing creatine that is ideal for development and growth in children.
Obtaining all of the essential amino acids that is needed in the daily diet requires that one meets their daily protein recommendation. Normally, a person is required to take an estimated 50 to 175 grams of protein every day. Even though essential amino acids can mostly be obtained from animal products, a combination of plant-based diets can also provide the nutrients. To those who may not be able to take certain animal and plant-based diets due to allergies or other reasons, it is advisable that you obtain over-the counter supplements of essential amino acids.
If you are buying essential amino acids supplements, you should always check the label to ensure that the product can provide all the nine. Besides, it is also advisable to talk to your nutritionist or doctor before starting on the supplementation program.
