If you don’t take in sufficient non-essential amino acids, you can actually increase your need for essential amino acids. For instance, your cells can manufacture non-essential cysteine from essential methionine. However, if you take in too little cysteine to meet your needs, you require extra methionine in your diet to make up the difference.
Essential amino acids are those you can’t manufacture and are therefore required in the foods you eat each day. A lack of even one of these can, over time, affect both your physical and mental health.
Of the 20 amino acids in the proteins of your body, you can make alanine, arginine, asparagine, aspartate, cysteine, glutamate, gluatamine, glycine, proline, serine and tyrosine but not histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan or valine.
For example, lysine is a limiting amino acid in grains such as wheat, meaning it is the essential amino acid present in the lowest amount in this food. A diet that relies on wheat as a staple can lead to a lysine deficiency. This could affect your mental health.
Protein in your diet provides structure to your cells and tissues – for example, your muscles and organs – and supports physiological functions like immune health, hormone production and cell-to-cell communication. Your body doesn’t store any excess amino acids you consume , which is why you need them in your diet each day.
During times of rapid growth, arginine may become essential to your diet as well, because your capacity to manufacture it might not keep up with your needs. The amino acids you are able to synthesize can come from modification of excess amino acids or from molecules produced during carbohydrate metabolism, but a lack of any ...
If this happens, then it is most likely that protein synthesis will be limited and won't produce enough of what the body needs. If this happens, structural components of the body tissue won't be provided with protein, leading to numerous complications.
