The optimal way to eat varies for each person, primarily based on their lifestyle (e.g., activity level), and to a lesser extent, environmental factors such as geographical location. That said, it is crucial not to transgress the bounds of anatomy and physiology, as Homo sapiens biologically most closely resemble frugivores. Thus, notwithstanding external influences, our fleshly frames function most efficiently on diets predicated on plants, particularly fresh fruits and vegetables, along with some seeds, nuts, and herbs.
