Diet Coke contains aspartame, a synthetic molecule that is 200 times sweeter than sucrose. It is normal to be skeptical of aspartame’s safety due to its chemical composition. However, there is a significant amount of evidence supporting the safety of aspartame. It is quickly broken down in the gut into phenylalanine, aspartic acid, and methanol, which are all normal substances found in many foods. Phenylalanine and aspartic acid are standard amino acids that we consume regularly, while methanol is a simple alcohol found in various fruits and vegetables. The FDA and other regulatory agencies have extensively studied aspartame and have approved its use as a food additive. While aspartame may not be completely risk-free, the relative risks of consuming aspartame versus other alternatives should be considered.
