Dietary diversity is vital for public health nutrition, yet the co-benefits of increasing dietary species richness (DSR) on human and environmental health remain unassessed. Here we explore associations between DSR and greenhouse gas emissions, land use, nutrient adequacy and mortality rates among European Investigation into Cancer and Nutrition (EPIC) study participants. Total DSR was positively associated with probability of adequate nutrient intake diet scores and inversely related to mortality rates; similar results were observed for plant DSR. Animal DSR was inversely associated with probability of adequate nutrient intake diet scores and neutrally associated with mortality rates. Neutral associations for total DSR and positive associations for animal DSR were found with greenhouse gas emissions and land use. Conversely, plant DSR was inversely associated with greenhouse gas emissions and land use. These findings from Europe suggest modest benefits of dietary plant biodiversity for nutrient adequacy and environmental health, with stronger inverse associations with mortality rates, while highlighting the potential adverse environmental impacts of diets rich in animal-sourced foods.
饮食多样性对公共卫生营养至关重要，但增加饮食物种丰富度（DSR）对人类和环境健康的协同效益仍未得到评估。在此，我们探讨了欧洲癌症与营养调查（EPIC）研究参与者中DSR与温室气体排放、土地利用、营养充足率和死亡率之间的关联。总DSR与充足营养摄入饮食评分的概率呈正相关，与死亡率呈负相关；植物DSR也观察到类似结果。动物DSR与充足营养摄入饮食评分的概率呈负相关，与死亡率呈中性关联。总DSR与温室气体排放和土地利用呈中性关联，动物DSR与温室气体排放和土地利用呈正相关。相反，植物DSR与温室气体排放和土地利用呈负相关。欧洲的这些研究结果表明，饮食植物生物多样性对营养充足和环境健康有适度益处，与死亡率有更强的负相关，同时突出了富含动物源食物的饮食对环境的潜在不利影响。
