What are concentrated sources of energy from animals or plants?

Concentrated sources of energy from animals include products like meat, dairy, and eggs, which provide high amounts of protein and fats that the body can efficiently convert into energy. From plants, concentrated energy sources include oils (such as olive and coconut oil), nuts, seeds, and starchy foods like grains and tubers, which are rich in carbohydrates. These sources are vital for both direct human consumption and as feed for livestock, supporting various food systems globally.
