GLOBAL – In a recent Joint Food and Agriculture Organization of the United Nations (FAO)/World Health Organization (WHO) Expert Consultation, experts have underscored the undeniable nutritional benefits of fish consumption while highlighting the need for a more nuanced approach due to potential exposure to methylmercury and dioxins.

While fish remains a vital source of energy, protein, and nutrients globally, the consultation emphasized the imperative of further research and tailored guidelines to address the varying risks and benefits associated with consuming fish.

Nutritional riches vs. contaminant concerns

Fish, encompassing fish and shellfish, stands as a culturally significant and nutritionally dense food source.

The consultation highlighted robust evidence linking fish consumption during all life stages to positive health outcomes, such as improved birth results for expectant mothers and reduced risks for cardiovascular and neurological diseases in adults.

However, the experts also recognized the pressing need for detailed regional, national, or subnational risk-benefit assessments, considering local dietary habits, fish contamination levels, and population demographics.

Data deficits and research imperatives

While acknowledging the existing evidence gaps, especially regarding the toxic effects of methylmercury and dioxins from fish consumption, the experts called for extensive research.

Specifically, they stressed the necessity of comprehensive studies addressing the relationship between fish intake and specific health outcomes.

They also urged exploration into contaminants’ contributions to human health issues across various populations.

Additionally, experts recommended investigating the impacts of food processing and preparation methods, as well as the distinct characteristics of fish consumed.

Strategies for informed consumption

The consultation on fish consumption has put forth essential recommendations to guide countries in navigating the complex realm of fish consumption.

First and foremost, there’s an emphasis on recognizing the pivotal role fish plays as a dietary source of essential nutrients while acknowledging its cultural significance.

Secondly, a holistic approach is encouraged, underlining the multifaceted health benefits of fish consumption that span across various life stages.

Data collection is another critical aspect, with a call to standardize the gathering of information on fish contaminants and nutrients at regional, national, or subnational levels.

Furthermore, a comprehensive approach to risk assessment is proposed, with tailored strategies for risk management and communication aimed at maximizing the benefits and minimizing the potential risks associated with fish consumption.

Addressing environmental impact

The experts also called for a broader perspective, urging future research to explore the aggregate effects of fisheries depletion on planetary health and its subsequent impact on public health, aligning with the United Nations’ Sustainable Development Goals.

In essence, the consultation emphasized the need for a balanced, research-driven approach to fish consumption, highlighting its nutritional bounty while acknowledging and mitigating potential risks.

Through tailored guidelines and informed decisions, countries can harness the nutritional riches of fish while safeguarding public health.
