It has long been recognized that an individual's lifestyle and dietary habits have a significant impact on their health status. They can either contribute to the development of various diseases or assist in their prevention. Furthermore, there is a connection between them and life expectancy. The Japanese, renowned for their longevity, are one of the nations with an average lifespan of 84 years. Therefore, it is worth paying attention to the rules they adhere to and their approach to nutrition.
What does shoku-iku truly signify?
Shoku-iku is a method of balanced nutrition that has become popular among Japanese people. In literal terms, it means nutrition education, but Asian society perceives shoku-iku as a combination of philosophy, tradition, and way of life. Due to the growing problem of obesity and civilization diseases (including in children), the Japanese government passed a law in 2005 that introduced a balanced nutrition system into school curriculums. It was a groundbreaking move because it was the first legal document in Japan to refer to a regulated way of eating. Students are educated in nutrition education from a young age, enabling them to familiarize themselves with the principles of healthy eating at an early stage of life when their habits are forming, which translates into a healthy lifestyle and healthy dietary choices in later years as well. It is worth noting that the education does not only pertain to the principles of nutrition - it is also a lesson about the origin and processing of food, the composition of meals, and the way of eating them so that they have a positive impact on health.
Fundamental dietary principles
Shoku-iku draws heavily on the scientific investigations conducted by Dr. Sagen Ishuzuki. The physician examined the nutritional value of the products making up traditional Japanese dishes, such as whole grain items, seafood, rare radish varieties, and kudzu. Ishuzuki also studied the connections between consumed food, environment, lifestyle, and body function. The fundamental principles of Japanese philosophy revolve around fortifying the body from within through proper nourishment and maintaining healthy habits. It is important to note that Japanese people view physical activity and adequate hydration as the basis for maintaining health. It is also significant to remember that shoku-iku does not focus on the caloric content of the diet or the prohibition of unhealthy products, but encourages conscious reduction of such products and finding joy in balanced nutrition.
The principles of shoku-iku nutritional education
Shoku-iku highlights the importance of paying attention to the signals transmitted by our body and listening to our own body in order to maintain balance. In accordance with Japanese philosophy, we should respect our body and avoid starvation or overeating. This also refers to the Confucian teaching of Hara hachi bun me, which states that a meal should end when we reach 80% satiety. The Japanese emphasize that mindful eating helps in controlling the amount of food consumed, maintaining proper body weight, preventing emotional eating, and limiting the need for a restrictive diet.
Diversity, a feast for the senses
Meals and products should be diverse and engage as many senses as possible. This principle is closely related to the theory of the five elements, also known as the concept of the five elements. The food should stimulate all taste receptors, so the correct composition takes into account the taste of sweet, salty, bitter, sour and umami. However, it is worth noting that the Japanese pay attention to the harmfulness of salt, so they use miso paste or soy sauce instead. It is also important that dishes are colorful (white, yellow, orange-red, green-blue, brown-black) to also appeal to the sense of sight. In addition, the smell is important, so aromatic herbs and fresh seasonal products are used. Structure and consistency are also important, so diversity stimulates the sense of touch. Preparing and eating food should also be associated with pleasant sound stimuli. Sounds such as crunching increase the attractiveness of food. Shoku-iku emphasizes the importance of diversity in the way meals are prepared. The Japanese are happy to eat raw products and also use methods that allow for the preservation of the nutritional value of the ingredients, such as steaming, grilling and simmering.
Locale and Time of Year in Nutrition
In line with the principles of shoku-iku, the diet should focus on seasonal products since they contain the highest amount of minerals and vitamins. Processing and storage significantly reduce their nutritional value. Importing raw food also results in a decrease in its health benefits, leading the Japanese to prefer local products. However, they avoid fast food. Grains play a vital role in the diet, accounting for 40-60% of daily caloric intake. Fruits, vegetables, seeds of leguminous plants, fish, seaweed, algae, and mushrooms are also highly significant components. It is worth noting that these are products rich in dietary fiber, which optimizes digestion, promotes a healthy gut flora, increases satiety, and prevents diseases, including colon cancer.
Communal consumption of meals
In the Japanese approach to nutrition, careful selection of ingredients is not the only consideration; the social aspect of meal consumption is also taken into account. According to the principles of shoku-iku, meals should be consumed peacefully and in the company of others. This not only satisfies physiological needs but also those related to group belonging and strengthening bonds. This practice is crucial for overall well-being and maintaining mental health. Scientific research supports that eating alone increases the risk of depression, obesity, cardiovascular diseases, and digestive disorders (Y. Kimura et al., 2012; T. Shirasawa et al., 2018; T. Miki et al., 2021; R. Sakurai et al., 2021; H. Choi, H. Kim, S. Kang, 2022).
Conscious meal scheduling
The Japanese are concerned about environmental protection, hence one of the key principles of shoku-iku is to avoid unnecessary food waste. They endeavor to show respect for food products and decrease waste by consciously scheduling meals and fully utilizing products. This aligns with the burgeoning zero waste trend, increasingly prevalent also in Poland, which aims to increase ecological balance.
Summary
Considering the positive outcomes of the shoku-iku food education approach, it is worth drawing inspiration from the Japanese method. Key is to pay attention to the signals sent by the body and choose nutritious foods, preferably those that are seasonal and locally sourced. It is also important to enjoy meals in a relaxed manner, taking pleasure in their taste, appearance, and aroma. It is good if the food consumed stimulates all senses. Meals should be a feast, best enjoyed in the company of acquaintances, friends, and family. It is also important to show concern for the environment by reducing waste.
