Scientific evaluation of Coke Zero:

After more than 2 scientific experiments, aspartame has been proved to be a very safe low-calorie sweetener. The sweetener has been used for more than 2 years and has been approved for use in more than 1 countries around the world. The European Food Safety Agency (EFSA) conducted a comprehensive safety test on aspartame, which once again confirmed its food safety.

Sucrose was synthesized in 1976 and approved for use in Canada in 1991. Later it was recognized by other countries and relevant international organizations. But the safety of sucralose is much less than that of aspartame. According to the safe intake stipulated by Canada, the "harmful dose" can only be achieved by ingesting sucrose equivalent to more than 6 grams of sucrose sweetness every day.

It can be seen that the sweetener in Coca-Cola Zero is quite safe in terms of scientific evidence and regulations of the competent authorities.
