Aspartame Resources: Reports on Aspartame Safety from Reliable Sources

HOW THE BODY HANDLES ASPARTAME

Aspartame is composed of two amino acids, aspartic acid and phenylalanine, as the methyl ester. Amino acids are the building blocks of protein. Aspartic acid and phenylalanine are also found naturally in protein containing foods, including meats, grains and dairy products. Methyl esters are also found naturally in many foods such as fruits and vegetable and their juices.

Upon digestion, aspartame breaks down into three components (aspartic acid, phenylalanine and a small amount of methanol), which are then absorbed into the blood and used in normal body processes. Neither aspartame nor its components accumulates in the body. These components are used in the body in the same ways as when they are also derived from common foods.

Further, the amounts of these components from aspartame are small compared to the amounts from other food sources. For example, a serving of no-fat milk provides about 6 times more phenylalanine and 13 times more aspartic acid compared to an equivalent amount of diet beverage sweetened 100% with aspartame. Likewise, a serving of tomato juice provides about 6 times more methanol compared to an equivalent amount of diet beverage with aspartame.
