Diet sodas are presented as an alternative to regular sodas, because they contain reduced or even zero calories and sugar, while retaining the taste of the original soda. Regular sodas are one of the biggest contributors to the increase in the rate of obesity cases around the world, particularly in the United States where sodas and other junk foods are easily accessed at cheap prices. Diet sodas can help people avoid unwanted weight gain, and are suitable for people with diabetes because the sugars in diet soda will not induce hyperglycemia. Despite the claimed benefit of diet sodas, there is also some controversy over the use of the artificial sweeteners found in them. One example of an artificial sweetener used in many diet sodas is aspartame. In small amounts, aspartame itself is relatively harmless. However, some of its metabolic constituents after being broken down may be dangerous to one’s health. Two of these harmful metabolites in particular are phenylalanine (an amino acid), and methanol (wood alcohol).

Excess phenylalanine can build up in the body and lead to phenylketonuria (PKU). People with PKU cannot effectively break down this excess phenylalanine, and if left untreated can lead to mental and behavioral disorders. Children born with PKU have a predisposition for eczema (inflammation of the skin). For someone with both PKU and psoriasis, excessive consumption of aspartame may worsen their symptoms.

Methanol, which is simplest form of alcohol, can normally be found in the body at low levels. It is like ethanol (drinking alcohol), but should not be consumed due to its harmful metabolic products. When methanol is metabolized, it is converted into formaldehyde, and then is later converted into formic acid which is toxic to the body’s central nervous system. Methanol does not directly affect the condition of psoriasis, but should still be avoided for general health.
