The International Agency for Research on Cancer (IARC) of the WHO (World Health Organisation) classified the sweetener aspartame (E951) as "possibly carcinogenic to humans" in July 2023. However more than one year on, aspartame is still on the market. This is an unacceptable health risk according to foodwatch, the Cancer League and Yuka who call for a ban with a European petition. 

Aspartame is still used as a sugar substitute in over 2,500 low-fat or sugar-free products in Europe particularly in soft drinks - Coca-Cola Zero, Pepsi Max, Sprite Zero, etc.-, energy drinks and chewing gum, as well as in other so-called 'light' products such as some Nestlé Lindahl dairy products and Mentos chewing gum. 

For over thirty years, independent research also associated aspartame with an increased risk of developing type 2 diabetes and cardiovascular disease. Finally, a number of studies show that it has no positive effect on weight and may even cause weight gain in the long term. 

In an unprecedented mobilisation, foodwatch, the Cancer League and Yuka are launching today a petition in eleven countries - Austria, Belgium, France, Germany, Italy, Ireland, Luxembourg, the Netherlands, Spain, Switzerland and the United Kingdom - to put pressure on the European institutions to ban aspartame and ask the EU Member States to take action. The precautionary principle enshrined in European regulations requires it to be banned.

Natacha Cingotti, Senior Campaigns Strategist at foodwatch International, says: "There's no time to lose. The inaction of governments and Europe over the last year and a half is intolerable. An additive with so many risks has no place in our food or drink. By highlighting the possible cancer risks associated with aspartame, the WHO has sent out a clear signal about the risk to our health. Our European decision-makers must protect us". 

Julie Chapon, Managing Director of Yuka, plans to mobilise the 45 million users of the app in Europe: "95% of Yuka users say they have stopped buying products containing controversial additives thanks to the app. We now want to empower consumers so that they can act as a lever for banning this risky additive". 

Philippe Bergerot, President of the Cancer League, sees "no reason to allow people to be exposed to a completely avoidable risk of cancer. The WHO and numerous scientific studies highlight this risk. We can't say we didn't know. We are asking our political decision-makers to shoulder their responsibilities and ban it". 

According to a YouGov poll commissioned by foodwatch, 40% of Europeans respondents regularly consume products containing aspartame. There is therefore a clear public health issue at stake here. All the more so since the French INSERM epidemiological study on aspartame carried out in 2022 on 102,865 participants identified the first risks of cancer from consuming just half a can of soda sweetened with aspartame soda pera day. The petition from foodwatch, the Cancer League and Yuka meets the expectations of two out of three European consumers surveyed who are in favour of a ban on aspartame as a precautionary measure. They would rather ask for a ban on aspartame (E951) than expose themselves to a health risk. 

In a report, foodwatch details the issues involved in assessing this highly controversial additive in terms of health. The assessment of aspartame by the European Food Safety Authority (EFSA) in 2013 was the subject of a number of criticisms concerning its conflicts of interest. 

foodwatch, the Cancer League and Yuka are determined to mobilise European consumers and get decision-makers moving: “Since it has not yet been proven that aspartame is fully safe, it should no longer be authorised on the European market”, said foodwatch's Natacha Cingotti.
