Does aspartame cause cancer?

No. Aspartame is one of the most thoroughly researched ingredients in the world. Authoritative bodies, such as the U.S. Food and Drug Administration (FDA) and European Food Safety Authority (EFSA), have reviewed the scientific data, including cancer studies, on aspartame. They have concluded it is safe for use in food and beverages.

The safety of our ingredients and beverages is really important to us. This includes the sugar substitutes we use in our products.

Does The Coca-Cola Company use aspartame?

Yes. We use aspartame as a sweetener in some of our drinks to help us keep the great tastes people love, but with fewer or no calories.

We use aspartame in Diet Coke, Coke Zero Sugar, Fanta Zero, Fresca and some of your other favorites.

Why do you use aspartame?

While sugar in moderation is fine, too much sugar isn’t good for anyone. It’s why we make reduced- and no-sugar versions for many of the drinks you love. We want to give you great-tasting choices with fewer or no calories. Aspartame helps us do this.

See how we’re reducing sugar in our products.


Is aspartame safe?

Yes. Aspartame is safe. It is one of the most thoroughly researched ingredients in the world. Science and health professional organizations have affirmed sugar substitutes, like aspartame, are safe. So have food safety authorities, like the FDA.

However, if you have the rare hereditary disorder phenylketonuria (PKU), you should strictly limit your intake of phenylalanine. This is a common amino acid found in aspartame. If we use aspartame, we say on our bottles and cans that there is phenylalanine so please check closely.

Have questions about PKU or your diet? Please talk to your doctor.


What is the acceptable daily intake (ADI) for aspartame?

ADI is set by the FDA. This is how much you can safely have each day. The ADI for aspartame is like a 132-pound adult having 75 tabletop packets. That’s about sixteen 12-oz cans of diet soda a day.
