Overview

E951 - Aspartame

Aspartame (E951) is a high-intensity sweetener about 200 times sweeter than table sugar, so only tiny amounts are needed to sweeten foods and drinks. It helps make “diet” and “sugar-free” products with fewer calories, but people with phenylketonuria (PKU) must avoid it because it contains phenylalanine.

E965II - Maltitol syrup

Maltitol syrup (E965II) is a sugar alcohol used to sweeten foods with fewer calories than sugar. It also adds bulk and moisture, making it useful in sugar-free candies, baked goods, and frozen desserts. It tastes similar to sugar and helps keep products soft.

Popular questions

Is aspartame bad for you?
For most people, no—regulators like EFSA, FDA, and WHO/JECFA consider aspartame safe at typical intakes within the acceptable daily intake (about 40–50 mg/kg body weight/day). People with phenylketonuria (PKU) must avoid it because it provides phenylalanine.
Does aspartame cause cancer?
Current evidence does not show a cancer risk at typical dietary exposures; EFSA, FDA, and WHO/JECFA have maintained its ADI and found it safe at current intakes. IARC classified it as “possibly carcinogenic” (Group 2B) in 2023 based on limited evidence, which did not change regulatory safety conclusions.
Does coke zero have aspartame?
Yes—Coca‑Cola Zero Sugar in many countries contains aspartame (often with acesulfame K); formulas can vary by market, so check your local label.
Why is aspartame bad for you?
It isn’t generally “bad” at normal food levels; the key exception is for people with PKU, who must avoid the phenylalanine it provides. Some individuals report sensitivities (e.g., headaches), so staying within the ADI is advised.
Does aspartame raise blood sugar?
No—aspartame does not raise blood glucose or insulin on its own and is considered suitable for people with diabetes within the ADI. Other ingredients in the food or drink may still affect blood sugar.
