Purpose of review 

The aim of this study was to summarize current contributions affecting knowledge and predictions about the nutritional adequacy of plant-free diets, contextualized by historical accounts.

Recent findings 

As demonstrated in recent experiments, nutrient interactions and metabolic effects of ketogenic diets can impact nutritional needs, sometimes resulting in nutrient-sparing effects. Other studies highlight conflicting hypotheses about the expected effect on metabolic acidosis, and therefore mineral status, of adding alkaline mineral-rich vegetables.

Summary 

A carnivore diet is a newly popular, but as yet sparsely studied form of ketogenic diet in which plant foods are eliminated such that all, or almost all, nutrition derives from animal sourced foods. Ketogenic diets are already nutritionally controversial due to their near-complete absence of carbohydrate and high dietary fat content, but most ketogenic diet advocates emphasize the inclusion of plant foods. In this review, we discuss the implications of relying solely on animal sourced foods in terms of essential nutrient status.

食肉动物饮食可以提供所有必需营养素吗？

审查目的 

这项研究的目的是总结对无植物饮食营养充足性的知识和预测产生影响的当前贡献，并根据历史记录进行背景分析。

最近的发现 

如最近的实验所示，生酮饮食的养分相互作用和代谢作用会影响营养需求，有时会导致养分浪费。其他研究突出了关于添加碱性富含矿物质的蔬菜对代谢性酸中毒的预期影响以及矿物质状态的相互矛盾的假设。

概要 

一个食肉动物的饮食是一个新近流行的，但至今人烟稀少的研究形式生酮饮食中植物性食物被淘汰，使得所有或几乎所有的，由动物营养来源导出的食物。由于生酮饮食几乎完全没有碳水化合物和高膳食脂肪含量，因此在营养方面已引起争议，但大多数生酮饮食倡导者强调将植物性食物包括在内。在这篇综述中，我们讨论了在基本营养状况方面仅依靠动物源性食品的含义。
