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.

Properly prepared legumes and grains, when consumed in moderation, can also be processed reasonably effectively by our bodies. Occasional inclusion of small amounts of meat, dairy, and eggs will typically result in no major ramifications—if one is in sound health, that is. However, those experiencing chronic challenges would be wise to eschew animal products (which produce excessive waste in the body and tax the organs), pulses, and cereals completely.

(It is essential to emphasize that, in addition to its health ramifications, from an ethical standpoint, I do not condone the consumption of animals or their byproducts when one does not depend on them for survival.)
