Catastrophes such as a nuclear war would generate atmospheric soot and reduce sunlight, making it difficult to grow crops. Under such conditions, people might turn to inedible plant biomass for nutrition, but the convertibility and nutritional content of this biomass have not been rigorously analyzed. We found that if plant biomass were converted into food at 30% efficiency, 6.7 kg of biomass per day would yield adequate carbohydrates, but contain potentially toxic or insufficient levels of other nutrients for a family of four. Therefore, exploiting biomass with low mineral content for carbohydrates and consuming other sources of protein, fat, and vitamins such as edible insects/single-cell proteins and vitamin supplements could provide a balanced diet in a global catastrophic environment.
诸如核战争这样的灾难会产生大气烟尘并减少阳光，从而使农作物难以生长。在这种情况下，人们可能会转向不可食用的植物生物质来获取营养，但这种生物质的可转化性和营养成分尚未得到严格分析。我们发现，如果植物生物质以30%的效率转化为食物，每天6.7千克的生物质将产生足够的碳水化合物，但对于一个四口之家来说，其他营养物质的含量可能有毒或不足。因此，利用低矿物质含量的生物质来获取碳水化合物，并食用其他蛋白质、脂肪和维生素来源，如可食用昆虫/单细胞蛋白质和维生素补充剂，可以在全球灾难性环境中提供均衡的饮食。
