Amino Acids are the building blocks of life
There are over 20 amino acids, essential and non-essential. Essential amino acids cannot be synthesised in the body, therefore, must be obtained from the diet. Non-essential amino acids can be synthesised in the body. A problem with the production of these non-essential amino acids can have detrimental metabolic effects.
Nutritionally essential amino acids
Arginine – is in short supply in children so may be considered essential
Histidine – is an essential amino acid for infants and also needed by adults
Non-essential amino acids
|Glutamine & Glutamic acid||Cysteine & cystine|
|b-Alanine||Gamma Aminobutyric acid (GABA)|
|Asparagine and Aspartic acid||Citrulline|
|Glutathione (Cysteine, glutamic acid, glycine)|
Most diets are abundant in protein, therefore we should be getting all the amino acids we need. Unfortunately, we are not living in a perfect world. Many factors prevent our bodies from using what we eat, i.e. pollution, hormones in the food chain, fertilisers, smoking, alcohol, food processing etc.
