    Complex network analysis and health implications of nutrient trade
    (Elsevier BV, 2024-03) Silvestrini MM; Smith NW; Fletcher AJ; McNabb WC; Sarti FM
    Food trade plays a key role in global nutrition, but the essential nutrients within this trade are understudied. We investigated the global nutrient trade network from 1986 to 2020, examining the relationship with income level and health outcomes. Bilateral nutrient trade data for 48 nutrients and 254 countries/economies was produced, made accessible through an interactive online application. Nutrients of interest in the context of food security and health (protein, calcium, iron, and vitamins A and B12) were examined using network analysis, animated graphs, and logistic regression to demonstrate the inequitable nature of nutrient trade, but its positive role in current nutrition-related disease. Food trade policy should be set with micronutrient content and deficiency in mind to address food security, nutrition, and health.

    Evolution of global food trade network and its effects on population nutritional status
    (Elsevier BV, 2023-06-03) Silvestrini MM; Smith NW; Sarti FM; Marangoni AG
    Changes in food systems during the last decades fostered the establishment of global food networks based on exchanges between countries with different income levels. Recent studies explored configuration and factors associated with trade networks of specific food items during limited periods; however, there is lack of evidence on evolution of trade networks of foods for human consumption and its potential effects on population nutritional status. We present the evolution of the global trade network of foods for human consumption from 1986 to 2020, according to country income level, and we explore potential effects of country network centrality and globalization processes on the prevalence of overweight and obesity. Results show intensification of international food trade and globalization processes in the period of analysis with implications for population nutritional status worldwide.
