What Is Aspartame in Diet Pepsi
Aspartame is an artificial sweetener used in Diet Pepsi to provide sweetness with few or no calories. It is made from two amino acids and is many times sweeter than sugar, so only a small amount is needed. Aspartame is one of the most studied food ingredients and is approved for use in many countries.
Why Diet Pepsi Uses Aspartame
Diet Pepsi uses aspartame to deliver a sweet taste similar to sugar while reducing calorie content. It helps maintain flavor in carbonated beverages without adding significant energy. Formulations may vary by region, and some versions use other low-calorie sweeteners instead.
Regulatory Status and Safety Overview
Regulatory agencies such as the U.S. Food and Drug Administration and the European Food Safety Authority have reviewed aspartame and consider it safe for the general population within accepted daily intake levels. People with phenylketonuria are advised to avoid or limit aspartame because they cannot metabolize phenylalanine properly.
