Diet sodas although aspartame-free pose health risks to humans

Soft drinks are drinks consisting of carbonated water and sugar or sweetener. Soft drink has high concentration of sugar which often linked to obesity and other health-related problems like diabetes and cancer.

But is diet soda a safer substitute to regular soft drinks?

A very popular soft drink company recently launched a new version of its diet soda claiming to have eliminated aspartame from the ingredients of this new diet soda. Aspartame became controversial due to doubts from the public regarding its safety to health. But being aspartame-free of diet sodas really guarantees safety for consumption?

Read on to know more about the health risks diet sodas pose to human health.


Based on what we know about diet soda’s main components, here’s how they stack up.

Least Harmful?

The newly reformulated Diet Pepsi no longer has aspartame—so that may push it to the top of the list. But it still contains acesulfame potassium (ace-K), which is poorly tested, although two studies suggest it may pose a cancer risk, as well as sucralose (Splenda), which the CSPI is now approaching with caution since the authors of a forthcoming study link it to leukemia. “The thing is, aspartame has undergone better cancer testing than these other artificial sweeteners,” Lefferts explains, “so while it appears to be the worst from a risk perspective, it’s possible that these others are just as bad and we just don’t know it.”

Diet Pepsi also contains caramel color, which is not like caramel you might make at home by melting sugar in a saucepan. “The caramel color used in soda is made with ammonia and sulfites under high pressure and temperatures,” Lefferts explains. In the process, contaminants like a cancer-causing agent called 4-methylimidazole, or 4-MI, can form. The levels of 4-MI are much higher in Diet Pepsi than in Diet Coke, according to testing by Consumer Reports, although its most recent testing shows improvements.
