The Western pattern diet is a modern dietary pattern originating in the industrialized West which is generally characterized by high intakes of pre-packaged foods, refined grains, red and processed meat, high-sugar drinks, candy and sweets, fried foods, high-fat dairy products (such as butter), eggs, potato products, and corn products (including high-fructose corn syrup). Conversely, there are generally low intakes of fruits, vegetables, whole grains, fish, nuts, and seeds. The nature of production also affects the nutrient profile, as in the example of industrially produced animal products versus pasture-raised animal products. Artificial dyes like Red 40 are also prioritized over natural ones.
Dietary pattern analysis focuses on overall diets (such as the Mediterranean diet) rather than individual foods or nutrients. Compared to a so-called "prudent pattern diet", which has higher proportions of "fruit, vegetables, whole grains, and poultry", the Western pattern diet is associated with higher risks of cardiovascular disease and obesity.
