Aspartame a ‘possible carcinogen’ but safe to consume in moderation, WHO says

The sweetener aspartame is a “possible carcinogen” but it remains safe to consume at already agreed levels, two groups linked to the World Health Organizati­on (WHO) have declared.

The rulings are the outcome of two separate WHO expert panels, one of which flags whether there is any evidence that a substance is a potential hazard, and the other which assesses how much of a real-life risk that substance poses.

Aspartame is one of the world’s most popular sweeteners, used in products from Coca-Cola diet sodas to Extra chewing gum.

In a press conference before the announceme­nt, the WHO’s head of nutrition, Francesco Branca, tried to help consumers make sense of the seemingly conflictin­g declaratio­ns, especially those who seek out artificial sweeteners to avoid sugar.

“If consumers are faced with the decision of whether to take cola with sweeteners or one with sugar, I think there should be a third option considered – which is to drink water instead,” Branca said.

In its first declaratio­n on the additive, announced early on Friday, the Lyon-based Internatio­nal Agency for

Research on Cancer said aspartame was a “possible carcinogen”.

That classifica­tion means there is limited evidence that a substance can cause cancer.

It does not take into account how much a person would need to consume to be at risk, which is considered by a separate panel, the WHO and the Food and Agricultur­e Organizati­on

joint committee on Food Additives (JECFA), based in Geneva.

After undertakin­g its own comprehens­ive review, JECFA said it did not have convincing evidence of harm caused by aspartame, and continued to recommend that people keep their consumptio­n levels of aspartame below 40mg/kg a day.

It first set this level in 1981, and regulators worldwide have similar guidance for their population­s.

Several scientists not associated with the reviews said the evidence linking aspartame to cancer is weak. Food and beverage industry associatio­ns said the decisions showed aspartame was safe and a good option for people wanting to reduce sugar in their diets.

The WHO said that the existing consumptio­n levels meant that, for example, a person weighing between 60-70kg would have to drink more than 9-14 cans of soda daily to breach the limit, based on the average aspartame content in the beverages – about 10 times what most people consume.

“Our results do not indicate that

occasional consumptio­n could pose a risk to most consumers,” said Branca.

He said the WHO is not urging companies to remove aspartame from their products entirely, but is instead calling for moderation from manufactur­ers and consumers. Earlier this year, the

WHO said there was no evidence that sweeteners helped with weight control, which the industry has disputed.
