During millions of years of evolution, human beings were largely subject to low-fat, high-carbohydrate diets (the foods generally available to our ancestors). The Paleolithic diet was based on lean meat, fish, fruits, vegetables, root vegetables, eggs and nuts [1,2]. The diet of late archaic hominid populations and their contemporaneous modern humans included marine food supply [3]. Modern civilization was born around the Mediterranean Sea. Ancient Greeks and Romans created a culinary culture that lasted for centuries, into present times [4]. For example, the Ancient Greeks used olives as their main source of fat instead of animal meat; they believed – in contrast to those they deemed barbarians – that animal fat was an unhealthy food. Olive oil was created to help preserve the olives. Barbarians ate more meat and animal products such as milk and cheese because they were nomadic and had less opportunity to grow olive trees or to prepare olive oil.
The discovery of America lead to the incorporation of new fruits and vegetables that enriched European gastronomy: tomatoes, corn, potatoes, chocolate, etc. In the 5th century BC Herodotus mentioned a fountain in the land of the Ethiopians, whose healing water was responsible of the exceptional longevity of this people. In Spain, during Moorish rule (from the 8th to the 15th century), stories about the water of eternal life or youth were very popular, and would have been known to the explorers who journeyed to America. Thus, in 1513 the Spanish explorer Juan Ponce de León claimed to have found “restorative waters” in what today is Florida.
