Research objective

  • To identify best practices and practical approaches for integrating sustainability into healthy eating guidelines on the island of Ireland.
  • To explore the potential policy implications of these approaches, based on existing literature and the experience, knowledge, and expertise of a broad range of stakeholders on the island of Ireland.
  • The research was conducted through five interconnected tasks: case studies of other countries, a literature review, consumer surveys, expert panel consultations, and focus group discussions.

Research report

  • Title: Building sustainability into national healthy eating guidelines
  • Publication date: 31 May 2023
  • Summary: Review of international practice and practical implications for policy.
  • Findings:

    Case studies: Seven countries where sustainability has been integrated into their dietary guidelines were analysed. Common practices included:

    • Basing guidelines on current eating patterns and health challenges.
    • Complementary policies and public consultations. Public involvement and pre-testing for understanding are crucial.
    • Focus on food waste reduction and promoting local, seasonal foods.
    • Recommendations to limit overconsumption, especially of processed foods.
    • Clear guidance on animal-based foods and other specific dietary aspects is needed.

    Literature review: A review of 54 journal articles highlighted factors influencing consumer behaviour towards sustainable diets:

    • Low awareness and understanding of the environmental impact of diets.
    • Scepticism about scientific evidence and the global impact of individual habits.
    • Multiple meanings of sustainable diets exist, with human health being a primary focus.
    • Strategies for promoting sustainable diets include early education and emphasizing the co-benefits of dietary changes.

    Consumer survey: A survey of 2,525 residents on the island of Ireland revealed:

    • The need to reconnect human and ecological health and to build awareness and knowledge about sustainable diets.
    • Affordability, accessibility, and nutrition are key factors influencing food purchases.
    • There is a mixed interest in reducing animal-based food consumption, with some already reducing red and processed meat.
    • Popular sustainable behaviours include eating home-cooked meals and reducing food waste.

    Expert panel: Combining evidence from various tasks, experts identified sustainable dietary guidelines for the island of Ireland and proposed actions including:

    • Proposed goals and actions to promote sustainable diets require policy coherence, shared responsibility across sectors.
    • Promoting plant-based diets and redefining the relationship with food.
    • Addressing vested interests and inaccuracies in policy and media.
    • Further research to resolve low agreement on some guidelines.

    Focus groups: Seven focus groups explored perceptions and potential issues with sustainable dietary recommendations. Findings included:

    • Low knowledge and awareness of sustainable diets.
    • Perceptions that sustainable diets are expensive and less accessible.
    • The need for clearer guidance on plant-based diets, red meat consumption, and processed vs. ultra-processed foods.
  • Recommendations:

    Policy development

    • Integrate sustainability into dietary guidelines with clear links to health and environmental benefits.
    • Ensure policy coherence and shared responsibility across sectors.
    • Align national agricultural efforts with sustainable consumer practices.

    Public awareness and education:

    • Increase awareness of the environmental impact of diets.
    • Promote early education on sustainable diets and their co-benefits.
    • Provide clear and transparent information on sustainable dietary practices.

    Support for sustainable practices:

    • Make sustainable choices more accessible and affordable.
    • Promote plant-based diets and reduce consumption of red and processed meats.
    • Provide clear guidance on distinguishing between processed and ultra-processed foods.
