Mayo Clinic expert weighs in on WHO labeling aspartame sweetener as low, but possible, cancer risk

A preferred synthetic sweetener that is extensively discovered in sugar-free meals and drinks is being labeled as a potential cancer risk by the World Health Organization (WHO). WHO’s cancer analysis company, International Agency for Research on Cancer (IARC), decided aspartame to be a potential carcinogen after reviewing and assessing the potential carcinogenic impact of the sweetener, but says it is protected to devour in restricted quantities.
Dr. Donald Hensrud, a Mayo Clinic doctor specializing in nutrition and the editor of “The Mayo Clinic Diet,” explains what this new classification means and why the risk is low.

“This new decision of declaring aspartame a possible carcinogen is going to add some confusion. First of all, the level of risk is low, but consuming something over many years, even in a low amount, may possibly add to the risk,” says Dr. Hensrud.
The 4 classifications of carcinogens
A carcinogen is a substance, organism or agent able to inflicting cancer. When classifying the risk that one thing causes cancer, IARC makes use of completely different ranges primarily based on the understanding of the proof of the risk. Those classes are:
- Carcinogenic to people
- Probably carcinogenic to people
- Possibly carcinogenic to people
IARC now labels aspartame as a potential carcinogen, the bottom of the three classes, indicating there may be restricted proof linking it to cancer.
“A definite carcinogen would be cigarettes,” explains Dr. Hensrud. “Cigarettes are known to cause lung cancer. However, we also know that not everyone who smokes gets lung cancer. Even with a definite carcinogen, there’s some element of uncertainty with regard to risk.”
What meals and drinks include aspartame
Aspartame is a nonnutritive sweetener that is not discovered naturally in the food provide and has no dietary worth. It’s used to offer sweetness with out energy in many alternative merchandise from weight loss plan sodas to sugarless gum.
Should nonnutritive sweeteners be prevented utterly?
“This new information on aspartame may cause some people to change their habits and cut down on foods that contain nonnutritive sweeteners. I don’t think it would be a step up to add foods that have sugar in them, such as going back to regular soda instead of diet soda. If people can look at this and make healthier choices overall, such as carbonated water with a splash of flavoring or something like that, that would be a much better choice than going to back to added sugars,” says Dr. Hensrud.
What’s the large takeaway?
“Overall, a healthy diet that is composed of minimally processed foods and mostly plant products is the healthiest. In that overall dietary pattern, if including some products with nonnutritive sweeteners helps to decrease overall calorie intake, that may be beneficial to some people,” says Dr. Hensrud.
“People may want to look at this information in the context of what they’re doing and perhaps take a fresh look at their overall habits.”
