Crowdsourcing and open data can increase transparency in the food industry. The presenter discusses Open Food Facts, a project launched in 2012 that uses crowdsourcing to collect and share nutritional and ingredient data on food products. Over 12,000 products have been added by 600 contributors. The data is made available under an open database license, allowing anyone to reuse it. This can help consumers make better choices and motivate food companies to improve products. The project aims to grow internationally and find more applications of the open data.
