Aspartame (E951) is a synthetic sweetener commonly used in sugar-free and diet drinks. It is derived from the amino acids phenylalanine and aspartic acid. Islamic jurisprudence evaluates food additives by considering factors such as their source, chemical transformation (istihâle), and whether they pose any harm to health.
Aspartame does not directly contain any haram substances, and it is free from animal products and alcohol. However, the production process may involve the use of alcohol as an additive. While aspartame does not have clear-cut harmful effects, some studies have linked it to possible health risks, such as cancer, migraines, and allergic reactions. The long-term impact on health is still not fully understood.
Given the potential health risks, it is advisable to avoid consuming aspartame, as it may conflict with Islam’s principle of avoiding harmful substances.
