Dietary protein is crucial for human health because it provides essential amino acids for protein synthesis. In addition, dietary protein is more satiating than carbohydrate and fat. Accordingly, many people consider the protein content when purchasing food and beverages and report ‘trying to eat more protein’. The global market for protein ingredients is projected to reach approximately US$90 billion by 2021, largely driven by the growing demand for protein-fortified food products. This Perspective serves as a caution against the trend of protein-enriched diets and provides an evidence-based counterpoint that underscores the potential adverse public health consequences of high protein intake.

膳食蛋白质对人类健康至关重要，因为它为蛋白质合成提供必需氨基酸。此外，膳食蛋白质比碳水化合物和脂肪更能满足饱腹感。因此，许多人在购买食品和饮料时会考虑蛋白质含量，并报告说“试图吃更多的蛋白质”。到 2021 年，全球蛋白质成分市场预计将达到约 900 亿美元，这主要是由于对蛋白质强化食品的需求不断增长。该观点对富含蛋白质的饮食趋势提出了警告，并提供了一个以证据为基础的对位，强调了高蛋白质摄入对公共卫生的潜在不利影响。
