"High in protein" refers to foods that contain a significant amount of protein relative to their total calorie content. Protein is an essential nutrient that helps build and repair tissues, supports immune function, and plays a crucial role in producing enzymes and hormones. Common high-protein foods include chicken, fish, beans, tofu, and Greek yogurt. In a balanced diet, incorporating high-protein foods can help with weight management and muscle maintenance. Many people choose high-protein diets to support fitness goals or improve overall health. It's important to combine these foods with other nutrients for a well-rounded diet.
