carbon dioxide production and, thus, carbon footprint. In order for a food to be characterized as “typical” of the Nordic diet, it has to fulfill a list of criteria, such as being produced within the Nordic countries without employing external energy sources, being related to Nordic dietary tradition (such as dark bread, root vegetables, and fish), being superior in terms of health effects compared to other foods of the same food group, and being consumed as food and not only in small amounts as dietary supplement, such as spices.
A detailed description of the Nordic dietary model and a sample menu plan can be found in Appendix B.9.
Take‐Home Messages
The Nordic diet is a plant‐based diet and refers to the dietary pattern recently developed in the Nordic region.
Compared to the Mediterranean and the DASH diets, the Nordic diet differs in the type of recommended oil and the vegetable and fruit choices.
The Nordic diet has been proven to have favorable health effects in controlling weight status and blood glucose and in reducing cardio‐metabolic and inflammatory markers.
A food is characterized as “typical” of the Nordic diet if it fulfills a list of criteria, such as being produced within the Nordic countries, being related to Nordic dietary tradition, superior in terms of health effects compared to other foods of the same food group, and consumed as food and not as dietary supplement.

The Healthy Asian Diet
Various aspects of the traditional Asian diet are followed by most Asian countries, including Bangladesh, Cambodia, China, India, Indonesian, Japan, Laos, Malaysia, Mongolia, Myanmar, Nepal, North Korea, South Korea, Philippines, Singapore, Sri Lanka, Taiwan, Thailand, and Vietnam. Although there are differences between countries, they all have many common food groups or items characteristic of the region.
The Asian diet is primarily characterized by high consumption of rice, foods of plant origin (e.g., soy products), fish and seafood, and fruits and vegetables. This dietary pattern includes fiber in amounts approximately threefold higher than a typical Western diet, whereas the consumption of red meat is usually very low. The majority of foods are boiled, steamed, or grilled without the addition of culinary fat, or fried with minimum quantities of seed oils, or they are consumed raw. Additionally, tea, a common drink among these populations, is drunk without sugar. Adherence to such a dietary pattern guarantees the intake of beneficial fatty acids, while limiting simple sugars and salt. The new Asian diet pyramid (Figure 6.3) was launched by the Oldways Preservation and Exchange Trust in 2018.
Key Point
The Asian diet is primarily characterized by high consumption of rice, foods of plant origin (e.g., soy products), fish and seafood, and fruits and vegetables.
The Japanese and the Chinese dietary patterns represent two well‐documented examples of the Asian diet. The “Dietary Guidelines for Japanese” were first published in 2000, and their latest version, namely, the “Japanese food guide spinning top” (Figure 6.4), was launched in 2010.
The illustration of these guidelines resembles the traditional Japanese spinning top toy, i.e., a turned‐upside‐down cone with separated layers displaying different foods. This illustration incorporates the number of servings for each food category.
Each food layer of the inverted cone reflects the frequency that each food should be consumed in a descending order. Cereal‐based dishes, such as rice, noodles, bread, and pasta are on top (five to seven servings/day), followed by vegetable‐based dishes (such as salads, cooked vegetables, and soups; five to six servings) and meat, fish, eggs, and soybean dishes (three to five servings/day). At the bottom of the spinning top are foods that are consumed daily in two servings, namely, fruits and dairy products. Snacks, sweets, and beverages with added sugar should be consumed in moderate doses and not on a daily basis. In addition to nutrition advice, the Japanese health guidelines include hydration and exercise recommendations. A glass of water with the prompt to drink enough water is shown at the highest point of the spinning top, while a man is running around the spinning top to reflect the recommendation for physical activity.

The Japanese dietary guidelines emphasize the planning of a regular meal schedule for the establishment of a healthy rhythm, eating well‐balanced meals, including staple foods, grains, vegetables and fruits, dairies, beans, and seafood, as well as enjoying both main meals and snacks. Furthermore, it highlights the avoidance of excessive amounts of salt and fat. Lifestyle recommendations are also included, such as managing body weight by controlling energy intake and being active and monitoring caloric intake. Finally, Japanese guidelines highlight the benefits of following the local dietary culture, avoiding food waste, and adopting suitable culinary practices and storage methods.
Key Point
Japanese guidelines highlight the benefits of following the local dietary culture, avoiding food waste, and adopting suitable culinary practices and storage methods.
Back in the 1950s, the Seven Countries Study, led by Ancel Keys, aiming to chart the incidence of CHD among seven countries (US, Japan, Italy, Greece, the Netherlands, Finland, Yugoslavia), underlined the effectiveness of the traditional Japanese diet in reducing CHD risk, as the Asian cohort demonstrated the lowest CHD incidence. The researchers from the Seven Countries Study concluded that the Asian diet was most effective in lowering CHD rates, although compared to the Greek cohort, Japanese showed more strokes due to the high sodium intake in Japan and higher stomach cancer rates due to traditional food preservation methods. Nevertheless, several studies have documented the beneficial role of specific dietary components of the Asian diet on various health outcomes.
Key Point
The researchers from the Seven Countries Study concluded that the Asian diet was most effective in lowering CHD rates.
Another example of dietary guidelines from Asia is that of China. The Chinese dietary guidelines were first launched in 1989 by the Chinese Nutrition Society. The Chinese dietary recommendations are illustrated by the “Chinese Food Guide Pagoda” (Figure 6.5), which consists of five gradually decreasing space levels, depicting the amount in which the foods of each level should be consumed.
The base of the pagoda is filled with cereals, such as rice, corn, bread, noodles, and crackers, as well as tubers.
