Animal food, also known as animal-based food, includes products that come from animals and are commonly consumed by humans for their high nutritional value. These foods include meat (such as beef, chicken, and pork), fish, eggs, and dairy products like milk, cheese, and yogurt. Animal foods are excellent sources of high-quality protein, essential amino acids, iron, zinc, and vitamins like B12, which are important for energy, muscle development, and overall body function. For example, fish is rich in omega-3 fatty acids, which support brain and heart health, while eggs provide a complete source of protein and important nutrients like choline. Although animal foods are highly nutritious, it is important to consume them in moderation and choose lean or low-fat options to maintain a healthy diet. They can be prepared in various ways—grilled, boiled, fried, or baked—and are a major part of many traditional diets around the world.
