Healthy dietary patterns, such as the alternate Mediterranean diet and alternate Healthy Eating Index, benefit cardiometabolic health. However, several food components of these dietary patterns are primary sources of environmental chemicals. Here, using data from a racially and ethnically diverse US cohort, we show that healthy dietary pattern scores were positively associated with plasma chemical exposure in pregnancy, particularly for the alternate Mediterranean diet and alternate Healthy Eating Index with polychlorinated biphenyls and per- and poly-fluoroalkyl substances. The associations appeared stronger among Asian and Pacific Islanders. These findings suggest that optimizing the benefits of a healthy diet requires concerted regulatory efforts aimed at lowering environmental chemical exposure. Data on chemical concentrations in commonly recommended diets are sparse. This study estimates the association between adherence to three dietary patterns considered healthy and exposure to environmental chemicals in a multi-racial pregnancy cohort, underscoring the need for increased regulation and monitoring of environmental contaminants.

Crop migration can moderate the impacts of global warming on crop production, but its feedback on the climate and environment remains unknown. Here we develop an integrated framework to capture the climate impacts and the feedback of adaptation behaviours with the land–water–energy–carbon nexus perspective and identify opportunities to achieve the synergies between climate adaptation and environmental sustainability. We apply the framework to assess wheat and maize migration in the North China Plain and show that adaptation through wheat migration could increase crop production by ~18.5% in the 2050s, but at the cost of disproportional increment in land use (~19.2%), water use (~20.2%), energy use (~19.5%) and carbon emissions (~19.9%). Irrigation and fertilization management are critical mitigation opportunities in the framework, through which wheat migration can be optimized to reduce the climatic and environmental impacts and avoid potential carbon leakage. Our work highlights the sustainable climate adaptation to mitigate negative environmental externalities. This study reveals that wheat migration as a strategy for climate adaptation lacks sustainability in the North China Plain. Irrigation and fertilization management provide mitigation opportunities to reduce negative environmental impacts and avoid carbon leakage.

Mariculture, or aquaculture in marine coastal environments, can contribute towards projected food demand increases. Greenhouse gas emissions from mariculture, including methane and nitrous oxide, could be 40% lower than emissions from land-based aquaculture.

Freshwater aquaculture is an increasingly important source of blue foods but produces substantial methane and nitrous oxide emissions. Marine aquaculture, also known as mariculture, is a smaller sector with a large growth potential, but its climate impacts are challenging to accurately quantify. Here we assess the greenhouse gas emissions from mariculture’s aquatic environment in global potentially suitable areas at 10 km resolution on the basis of marine biogeochemical cycles, greenhouse gas measurements from research cruises and satellite-observed net primary productivity. Mariculture’s aquatic emissions intensities are estimated to be 1–6 g CH4 kg−1 carcass weight and 0.05–0.2 g N2O kg−1 carcass weight, >98% and >80% lower than freshwater systems. Using a life-cycle assessment approach, we show that mariculture’s carbon footprints are ~40% lower than those of freshwater aquaculture based on feed, energy use and the aquatic environment emissions. Adoption of mariculture alongside freshwater aquaculture production could offer considerable climate benefits to meet future dietary protein and nutritional needs. Combining observations and biogeochemical theories, mariculture greenhouse gas emissions are estimated in comparison with freshwater aquaculture. Climate-friendly farm designs, species selection and low-density operational practices can mitigate damage to marine ecosystems and avoid carbon loss.
淡水养殖是日益重要的蓝色食品来源，但会产生大量甲烷和氧化亚氮排放。海水养殖（又称海产养殖）是一个规模较小、增长潜力巨大的行业，但其对气候的影响却难以准确量化。在此，我们根据海洋生物地球化学循环、研究考察船的温室气体测量结果以及卫星观测到的净初级生产力，以 10 千米的分辨率评估了全球潜在适宜区域海水养殖水生环境的温室气体排放量。据估计，海水养殖的水生排放强度为 1-6 g CH4 kg-1 体重和 0.05-0.2 g N2O kg-1 体重，分别比淡水系统低 98% 和 80%。我们使用生命周期评估方法表明，根据饲料、能源使用和水生环境排放，海水养殖的碳足迹比淡水养殖低约 40%。在淡水水产养殖生产的同时采用海水养殖可提供可观的气候效益，以满足未来的膳食蛋白质和营养需求。

Large-scale food fortification (LSFF) can increase dietary micronutrient intake and improve micronutrient status. Here we used food balance sheet data from the Food and Agriculture Organization of the United Nations to estimate current country-specific prevalences of inadequate zinc intake. We assessed the potential effects of improving existing LSFF programmes for cereal grains or implementing new programmes in 40 countries where zinc deficiency is a potential public health problem. Accounting for LSFF programmes as currently implemented, 15% of the global population (1.13 billion individuals) is estimated to have inadequate zinc intake. In countries where zinc deficiency is a potential public health problem, the implementation of high-quality mandatory LSFF programmes that include zinc as a fortificant would substantially increase the availability of zinc in the national food supply, reducing the estimated prevalence of inadequate zinc intake by up to 50% globally. Investments in strong LSFF programmes could have a substantial impact on population zinc status. Using food balance sheet data from the Food and Agriculture Organization of the United Nations, this study shows that mandatory large-scale food fortification programmes in the 40 countries where zinc deficiency is considered a public health problem could considerably reduce the prevalence of inadequate dietary zinc intake globally.

Building soil health and manipulating the soil microbiome, alongside targeted plant breeding that prioritizes preferential root architectural development, hold the key to the future success of regenerative agriculture.
