Is Coca-Cola Zero bad for you?

Coca-Cola Zero Sugar contains no sugar and essentially no calories, which makes it a popular swap for regular cola when you're trying to cut calories. Instead of sugar, it's sweetened with aspartame and acesulfame potassium (Ace-K).

Major food-safety bodies including the FDA and EFSA consider these sweeteners safe at normal intake levels. That said, the drink provides no vitamins, minerals or other nutritional value, and the phosphoric acid and caffeine are worth being mindful of.

For most people, an occasional Coke Zero is fine. If you drink several per day, consider alternating with water or naturally flavored sparkling water.
