Evolution of human diet and effect of globalization on regional diet with emphasis to the Mediterranean diet

Abstract

Purpose The Mediterranean Diet (MD) is an expression of different Mediterranean food cultures and lifestyles. It is characterized by high consumption of olive oil, vegetables, legumes, whole grain products, fruits and nuts. This paper aims to emphasize on the evolution of human diet from earliest human ancestors to current civilization, the effect of MD on human health and the role of globalization to shift traditional diet, particularly MD to processed foods. Design/methodology/approach Different published papers were collected from the internet by using the following phrases: evolution of human diet, human ancestors, the effect of globalization on a regional diet, Mediterranean diet, healthy food, food pyramid, evolution of human diet and effect of globalization on diet. Finally, the papers were read and summarized as a review paper. Findings MD has been accepted worldwide owing to its health impact such as prevention and control of type 2 diabetes, anti-inflammatory effects and decrease in the risk of cardiovascular diseases and incidence of Parkinson’s disease and Alzheimer’s disease. However, in conjunction with this discordance between our ancient, genetically determined biology and the nutritional, cultural and activity patterns of contemporary Western populations, many of the so-called diseases of civilization have emerged. Particularly, the food staples and food-processing procedures introduced during the Neolithic and Industrial periods have fundamentally altered nutritional characteristics of ancestral hominin diets. MD is currently under the risk of extinction for a result of the effects of globalization. Originality/value The review paper focuses on the evolution of human diet as an effect of globalization on the regional diet with emphasis on the MD. It specifically focuses on the link between diet and earliest human ancestors, about MD and its health benefit, diet pyramid and effect of globalization on regional diet.
