Aspartame and the GERD Friendly Diet

Aspartame is an artificial sweetener known for its low-calorie content. It is approximately 200 times sweeter than sucrose (table sugar), allowing it to be used in small quantities to achieve the desired sweetness. First approved for use in food products in the 1980s, it is widely used in a variety of food and beverage products, particularly those marketed as low-calorie or sugar-free. Chemically, aspartame is a methyl ester of the aspartic acid/phenylalanine dipeptide.
