human nutrition
MyPlate, a revised set of dietary guidelines introduced by the U.S. Department of Agriculture (USDA) in 2011, divides the four basic food groups (fruits, grains, protein, and vegetables) into sections on a plate, the size of each section representing the relative dietary proportions of each food group. The small blue circle shown at the upper right illustrates the inclusion and recommended proportion of dairy products in the diet.
Cultural traditions and food preferences significantly shape human nutrition by defining what is considered edible, desirable, or forbidden within a society. These customs often function like a system of rules, where symbolic valuesârather than strictly nutritive factorsâdictate dietary choices.1
Cultural Influence on Nutrition
- Dietary Taboos: Many cultures impose restrictions based on religious or symbolic beliefs. For example, some hunter-gatherer groups, such as the Inuit, maintain strict taboos separating land and sea products to ensure success in hunting and personal health.2
- Geographic and Economic Factors: Historically, nutrition was dictated by local availability. Today, while globalization allows for the transport of food, economic status remains a primary driver; affluent populations typically consume more meat and animal products, while those in agricultural regions rely heavily on staples like wheat, rice, or corn.3
- Health Outcomes: Traditions can have profound physiological impacts. The Mediterranean diet, for instance, is associated with higher life expectancy due to its reliance on olive oil and antioxidant-rich vegetables rather than animal fats. Conversely, the global convergence toward a diet high in processed sugars and animal products has contributed to rising rates of obesity and diabetes.34
