Abstract
Proteins are essential nutrients that contribute to the structure of various cells and tissues in the body. Consuming adequate protein in our diet is crucial for optimal health and bodily function. This review article explores the role of dietary proteins by examining global consumption patterns and consumer perceptions of high-protein diets. It investigates recent research trends regarding the impact of proteins on human health and wellness across various countries and communities. The review analyzes key health outcomes associated with very high-protein diets, especially those exceeding recommended values. It includes the latest evidence on the influences of animal and plant proteins on health in different groups of participants. Furthermore, this manuscript delves into the scientific discussion surrounding the optimal amount of protein in the human diet.
