High-protein foods are those that contain a significant amount of protein, which is an essential nutrient for the body. Protein plays a crucial role in building and repairing tissues, making enzymes and hormones, and supporting overall health. Common high-protein foods include meat, fish, eggs, dairy products, legumes, and certain grains like quinoa. A diet rich in protein can help with weight management, as it promotes feelings of fullness and can reduce overall calorie intake. Additionally, high-protein diets are often recommended for athletes and those looking to build muscle, as protein is vital for muscle growth and recovery after exercise.
