Global challenges such as climate change, biodiversity loss, and health crises necessitate a shift towards sustainable diets. Incorporating sustainability into food-based dietary guidelines (FBDGs) is essential for this shift, and cultural considerations also play a vital role, as food culture significantly influences dietary habits. Considering that Asia and Europe exhibit distinct food cultures, tailored approaches are necessary. Additionally, countries face diverse nutritional challenges, ranging from malnutrition to diet-related diseases, and regional variation in environmental impact necessitates context-specific strategies. Achieving sustainable nutrition depends on understanding cultural influences and regional dynamics. This paper compares China’s and Germany’s dietary guidelines and dietary patterns and their impact on sustainability. It shows that Chinese and German FBDGs only slightly differ, despite the different eating cultures and habits of each country. Alone the recommended amounts for eggs and fish are considerably higher in China than in Germany. However, in both China and Germany, actual dietary patterns deviate from the dietary guidelines. In China, concomitant with economic growth and urbanization, a dietary shift towards increased consumption of animal products and decreased consumption of vegetables and cereals has been observed in the last decades, which has led to a decline in nutritional deficiencies but an increase in obesity and overweight. Obesity and overweight are also on the rise in Germany. A dietary shift could therefore also be beneficial for public health. While following the respective national guidelines would benefit the environment, alternative diets such as a plant-based diet offer even lower environmental footprint. Revising guidelines to prioritize sustainability in addition to health aspects while considering regional contexts and cultural preferences is recommended to foster sustainable eating habits globally. This approach is pivotal for promoting dietary shift towards sustainability on a global scale.
