Abstract Unhealthy food is one of the prevailing risk factors of NCDs and cancers, making the food industry a key player in their prevention. However, evidence-based public health policies aimed at reducing consumption of unhealthy food, may threaten industry sales. In response, food industry actors try to influence the development and implementation of these nutritional policies by engaging in corporate political activities (CPA). As part of the Joint Action PreventNCD, the CPA of relevant food industry actors in relation to public health nutritional policies will be assessed. In Belgium, strategies of Fevia, the umbrella organization of the food industry, are examined. This study analyses publicly available information collected from Fevia’s website, social media accounts (i.e. X and LinkedIn), newsletters and newspapers. A thematic qualitative analysis is conducted using established frameworks to categorize both framing and action strategies used by the industry. The categorization of framing strategies reveals how the food industry presents the actors, problems, and solutions. The framework of action strategies categorizes the CPA of the food industry under the following six strategies: information and messaging; financial incentives; constituency building; legal action; policy substitution; opposition fragmentation and destabilization. Preliminary results indicate that the industry often frames itself as ‘the good actor’ and primarily uses strategies such as ‘information and messaging’, ‘constituency building’ and ‘policy substitution’ to influence policies in Belgium in their favor. In the next phase, interviews with stakeholders (e.g. policymakers, politicians,...) will be performed to collect undocumented information. Overall, this research sheds light on the ongoing CPA of the food industry and will increase transparency in their influence on the development and implementation of effective nutritional policies aimed at reducing the burden of NCDs and cancers. Key messages • This study reveals how the umbrella organization of the food industry in Belgium influences public health nutritional policies through various corporate political action and framing strategies. • Identifying these CPA increases awareness of the industry’s influence, but also promotes their transparency and accountability, which is crucial for reliable and effective nutritional policy.
