Swiss people consume an average of 107g of sugar per day whereas a maximum of 50g is recommended. During May 2023, the MAYbe Less Sugar initiative invited people from the French-speaking part of Switzerland to investigate their use of added sugar. An online calculator enabled them to evaluate it so they could take action. The campaign reached 6 920 participants and more than 11 000 people via the website maybeless-sugar.ch and social networks. In addition, numerous events and media coverage have put sugar at the heart of the debate. Although people who overconsume sugar were targeted, they are still difficult to reach. The 37 partners plead for MAYbe Less Sugar to be continued and involve health professionals as well as politicians in order to change behaviors but also the environment that should become conducive to health for everybody.
