The Paleo Diet is suitable for our genetic make-up because it consists mainly of fruits, nuts, meats, poultry, seeds and wild plants. It is the most reasonable nourishment for a healthy human body: in fact, we cannot deny that people from previous generations were devoid of diseases like obesity, arthritis, diabetes, and hypertension that many of us suffer from today. Therefore, to avoid this, people should not eat the artificial preservatives and other substances that can harm them and that unfortunately fill most food today.
