在美国和加拿大，预防大多数人缺乏所需的膳食蛋白质量由推荐膳食允许量定义，目前设定为0.8 g蛋白质。kg（-1）。d（-1）成人。为了满足这一蛋白质建议，建议摄入各种蛋白质食物来源。这篇文章的目的是表明，通常食用的蛋白质食物来源不仅仅是蛋白质，而且是必需营养素的重要来源。通常食用的膳食蛋白质来源通常对诸如钙、维生素D、钾、膳食纤维、铁和叶酸等营养素的摄入有很大贡献，这些营养素已被确定为“关注”的营养素（即，摄入量往往低于推荐量）。尽管如此，减少饱和脂肪和固体脂肪摄入量的饮食建议可能会导致饮食指导减少通常食用的蛋白质食物来源的摄入量，特别是动物性蛋白质。我们建议，遵循这样的膳食指南将很难达到一些营养素的推荐摄入量，至少在饮食消费模式没有明显变化的情况下。这些明显相互矛盾的膳食指南很难调和;然而，我们认为建议摄入高质量的膳食蛋白质以确保足够的营养素摄入量是谨慎的，特别是关注的营养素。
The amount of dietary protein needed to prevent deficiency in most individuals is defined in the United States and Canada by the Recommended Dietary Allowance and is currently set at 0.8 g protein . kg(-1) . d(-1) for adults. To meet this protein recommendation, the intake of a variety of protein food sources is advised. The goal of this article is to show that commonly consumed food sources of protein are more than just protein but also significant sources of essential nutrients. Commonly consumed sources of dietary protein frequently contribute substantially to intakes of nutrients such as calcium, vitamin D, potassium, dietary fiber, iron, and folate, which have been identified as nutrients of "concern" (i.e., intakes are often lower than recommended). Despite this, dietary recommendations to reduce intakes of saturated fat and solid fats may result in dietary guidance to reduce intakes of commonly consumed food sources of protein, in particular animal-based protein. We propose that following such dietary guidance would make it difficult to meet recommended intakes for a number of nutrients, at least without marked changes in dietary consumption patterns. These apparently conflicting pieces of dietary guidance are hard to reconcile; however, we view it as prudent to advise the intake of high-quality dietary protein to ensure adequate intakes of a number of nutrients, particularly nutrients of concern.
