Belgian dietitians' knowledge, perceptions and willingness-to-recommend of genetically modified food and organisms.

BACKGROUND: Dietitians play a critical role in the public's relationship with food and are often overlooked as an important stakeholder group in the general debate about sustainable food. Genetically modified organisms (GMOs) are one type of modern food source that could contribute to a more sustainable food system. This case study is the first to examine the knowledge, perception and willingness-to-recommend (WTR) genetically modified (GM) foods by dietitians in Europe. METHODS: An online survey was addressed to all members of the Flemish Association of Dietitians (Belgium) in 2021, resulting in a sample of 98 valid responses. Multivariate linear regression included sociodemographic, knowledge, and attitudinal factors as the independent variables to explain dietitians' WTR. RESULTS: Flemish dietitians had limited knowledge of GMOs; only about half of the GM questions were answered correctly. Most dietitians (53%-76%) would recommend GMOs with positive effects on human nutrition or sustainability, whereas few dietitians (19%-27%) would recommend other GMO applications. Trust in GMO information sources and perceived GM benefits significantly influenced a positive WTR of GM foods. Predominant negative information about GM foods was significantly associated with dietitians' low trust and WTR such foods. CONCLUSIONS: Countering the predominantly negative portrayal with more neutral and factual information could improve trust, which in turn could positively influence dietitians' perceptions towards GMOs. By further examining the knowledge and perception of dietitians worldwide GMOs and gene-edited products, new insights could be could gathered into the positioning of this underexposed stakeholder group.

The role of orphan crops in the transition to nutritional quality-oriented crop improvement.

Micronutrient malnutrition is a persisting problem threatening global human health. Biofortification via metabolic engineering has been proposed as a cost-effective and short-term means to alleviate this burden. There has been a recent rise in the recognition of potential that underutilized, orphan crops can hold in decreasing malnutrition concerns. Here, we illustrate how orphan crops can serve as a medium to provide micronutrients to populations in need, whilst promoting and maintaining dietary diversity. We provide a roadmap, illustrating which aspects to be taken into consideration when evaluating orphan crops. Recent developments have shown successful biofortification via metabolic engineering in staple crops. This review provides guidance in the implementation of these successes to relevant orphan crop species, with a specific focus on the relevant micronutrients iron, zinc, provitamin A and folates.
