What are aspartic acid and phenylalanine, and what are their roles as ingredients in the manmade product called aspartame? Is aspartame dangerous or linked to cancer? Many claims exist, but here are some facts and information on the subject, which you might want to consider.
First of all, aspartame is an artificial sweetener; it is known as NutraSweet® and Equal® as well as Spoonful, and Equal-Measure, and is claimed to be up to 200 times sweeter than sugar. Aspartame was, in 1981, approved for use in dry goods, and later in 1983 approved for carbonated beverages. Aspartame basically has three main ingredients: aspartic acid, phenylalanine, and methanol.
I will go briefly over these three ingredients below and then discuss their use in aspartame…
Amino acids are the building blocks of proteins, and aspartic acid, also known as asparaginic acid, is a non-essential amino acid. “Non-essential” means that it is not necessary to get this amino acid from food or supplements since the human body makes it on its own. Our bodies need and use aspartic acid within cells to help the body work, especially regarding nervous system functioning, and hormone production/release.
Phenylalanine is also an amino acid, but an essential amino acid, which means it can only be gotten from food (our body does not make it on its own). Phenylalanine is the precursor for the amino acid tyrosine, which acts as a neurotransmitter in our brain for signaling dopamine, norepinephrine (noradrenaline), epinephrine (adrenaline), and melanin (skin pigment).
Phenylalanine is also found in breast milk and is a necessary nutrient for newborn babies, which is why it is added to baby formulas. Phenylalanine is a nutritional supplement in food and drink products and is known for its antidepressant and analgesic effects.
All 22 common amino acids, including aspartic acid and phenylalanine, can be gotten from protein foods such as meats, fish, and eggs, and smaller amounts from dairy, legumes, nuts, and vegetables.
Where aspartic acid and phenylalanine are natural substances, and needed for proper bodily functioning, methanol is toxic to the human body. Methanol is known as wood alcohol, methyl alcohol, wood naphtha, or wood spirits and is a chemical produced mostly as a byproduct of the destructive distillation of wood. Modern methanol is produced industrially from hydrogen, carbon monoxide, and carbon dioxide. Methanol is simple as alcohols go, flammable, volatile, colorless, and sweeter than ethanol (drinking alcohol). Methanol is used for producing biodiesel, as a fuel, denaturant for ethanol, and is a greenhouse gas.
Ingesting large quantities of methanol causes it to be metabolized to formate salts and formic acid. These may cause coma, blindness, or even death, because they are poison to the central nervous system. Special emphasis on “large quantities.” Why? Keep reading…
