SWEET, a European Commission Horizon 2020 funded project, is supported by a consortium of 29 pan-European research, consumer and industry partners, who will develop and review evidence on long term benefits and potential risks involved in switching over to sweeteners and sweetness enhancers (S&SEs) in the context of public health and safety, obesity, and sustainability.
The 5 year multidisciplinary project engages stakeholders from across the food chain — consumers, patients, health professionals, scientists, policy makers, and regulators — to address the role of sweeteners in weight control, and potentially move viable products to market. Stakeholders, including consumers, patients, health professionals, scientists, policy makers, and regulators will engage in the project.
