In a rejoinder to Gill et alia (2021), Martin (2022) accuses us of perpetuating misconceptions about human nutrition and erroneously describing geophytes as a dietary staple. We provide authoritative definitions for the terms “essential” and “dietary staple” to show that it is Martin who mischaracterizes and misunderstands the foundational role of geophytes and other plant foods to human diets and subsistence economies in Native North America outside of the Arctic. Recent data demonstrate that carbohydrate-rich geophytes were abundant, regularly utilized, and essential resources on the Northern Channel Islands, a dietary staple that was a rich source of calories and complemented the protein-rich shellfish and finfish that were also staple foods for the Island Chumash.

在对 Gill 等人 (2021) 的反驳中，Martin (2022) 指责我们长期存在对人类营养的误解，并错误地将地球植物描述为主食。我们为术语“基本”和“主食”提供了权威定义，以表明是马丁错误地描述和误解了地球植物和其他植物性食物对北极以外北美原住民的人类饮食和自给经济的基础作用。最近的数据表明，北海峡群岛富含碳水化合物的地球植物是丰富、经常利用和必不可少的资源，这是一种富含卡路里的主食，并补充了也是该岛主食的富含蛋白质的贝类和鱼类楚马什。
