Infectious disease presents a serious threat to our fitness. The biological immune system provides several mechanisms for dealing with this threat. So too does another system: the behavioral immune system. This second system is proposed to consist of a set of evolved cognitive, affective, and behavioral strategies for reducing the likelihood of infection, including xenophobia, traditionalism, and food neophobia. In the present work, I investigate how another suite of fairly novel culturally-learned disease avoidance strategies, namely hygiene behaviors and knowledge of germ theory, are related to the behavioral immune system. Across two studies, I find that individuals who engage in more hygiene behaviors show less evidence of reliance on several elements of the behavioral immune system (i.e., xenophobia, traditionalism, food neophobia). Similarly, individuals who know more about germ theory show less engagement in behavioral immune system components. These findings suggest that effective cultural strategies for avoiding infectious disease may supplant older, evolved psychological strategies with the same purpose.

A brief history of the Mediterranean diet and its geographical origins as a meeting point for cultures will guide understanding of the construction of this specific dietary pattern. The nutrients and foods typical of the Mediterranean diet will be outlined as well as their health benefits, allowing for a deeper analysis of the ways in which the Mediterranean diet is associated with reducing the risk of certain chronic diseases. The lifestyle choices and physical activity practiced adjacently to the diet will establish the positive synergistic effects of conviviality and moderate exercise on general human health. Contemporary movements in the Mediterranean region, like Slow Foods, aim to preserve traditional dietary and lifestyle choices. In comparison, the U.S. food system seems to be most shaped by the influences of globalization and industrialization. Economic and health-cost perspectives as well as the role of modern-day media in diet trends, body image, and food marketing will establish and deepen the complexities of food choices and health disparities in Western societies. The diagnosis of the Mediterranean Diet in the U.S. as a solution to poor general population health will be challenged and holistic perspectives on eating will provide an exploratory lens for understanding health and food choice as a modern-day consumer.
