A principle of the Okinawan diet, which overlaps with the traditional Japanese diet, is hara hachi bu, which loosely translates to “eat until you are 80 percent full.” This concept is traced back to the island city of Okinawa, which boasts the highest number of people over the age of 100 worldwide. Traditional wisdom taught that eating just until you are no longer hungry, rather than until you are full, can cut down on overeating and digestion issues and reduce calorie intake. Okinawans have long life expectancies and some of the lower rates of heart disease, stroke, dementia, and cancer in the world. It’s unlikely that their diet is the sole reason for this, as genetics, lifestyle, and other risk factors contribute to these conditions. However, it stands to reason that a philosophy that promotes healthier eating would naturally lead to a healthier, longer-living population.
This is a hard blow for some. Few traditional Japanese foods have added sugar. Desserts are not a large part of the traditional Japanese diet and are very different from most Western desserts. Traditional Japanese sweets, called wagashi, tend to be low in added sugar and use natural, rather than processed, ingredients. While refined sugars are largely absent in many wagashi, fresh fruit and simple ingredients like matcha (green tea powder), red bean paste, and mochi (a cake made of glutinous rice) are the stars. These treats are usually made with plant-based ingredients and are typically served with green tea to cap off the meal. Desert portions also tend to be quite small compared to those in Western diets. Baked goods like cakes, pastries, and cookies are mostly absent in the traditional Japanese diet, although they have gained popularity in modern cuisine.
Use Fresh, Seasonal Ingredients Instead of Frozen or Canned
Japanese cuisine is deeply rooted in the concept of using fresh, seasonal ingredients (called shun) that are simple and minimally processed. Each season influences the dishes that are central to each meal. Spring dishes feature snow peas, shitake mushrooms, cherry blossoms, and strawberries. Seafood like squid, flounder, and herring are eaten fresh or cooked into soups. In the summer, eggplant, shishito peppers, cucumber, and melons take center stage, along with eel, sea urchin, and sea bass. The cooler weather of autumn brings mushrooms, chestnuts, pear, and persimmon to the forefront with salmon, mackerel, and octopus. Finally, the winter months are characterized by meals featuring cabbage and root vegetables, citrus, oysters, and yellowtail.
We’re all guilty of neglecting our water intake. But the human body is about 60 percent water. So water is absolutely essential for our bodies to function normally. Drinking water and other fluids throughout the day can help you stay hydrated. But foods with ahigh water content can also be key to replenishing the water that is lost naturally from sweating, going to the bathroom, and even breathing. Staying hydrated keeps your organs working properly, regulates your body temperature, removes waste and impurities, and promotes good digestion. Many foods that feature heavily in a Japanese diet, including cucumbers, lettuce, watercress, and broth, are loaded with water and lots of other nutrients that help you replenish your body’s fluids. These foods are low-calorie, filling, and nutrient-rich.
Soybeans and soy products are ubiquitous in Japanese cuisine. From edamame (immature soybeans) and natto (a pungent dish made from fermented soybeans) to tamari (a sauce similar to soy sauce made from fermented soybeans) and tofu (made by pressing curdled soy milk into blocks), you would be hard-pressed to eat a traditional Japanese meal that doesn’t have at least one soy element. Soy products are a rich source of protein without the saturated fat and cholesterol of meat and dairy. They’re also packed with isoflavones, which are anti-inflammatory and promote heart health. High consumption of soybeans has been linked to lower blood pressure and reduced risk of cardiovascular disease.
Sip your way to better health with green tea. By far, the most common drink in a traditional Japanese diet is green tea. It’s a staple of most meals. In Japan, green tea is typically served hot without added sweeteners or dairy, making it a low-calorie and hydrating drink. This tea has many health benefits, including boosting the immune system, maintaining healthy blood pressure, blood sugar, and cholesterol levels, and promoting overall health. Some studies have even suggested that green tea may reduce the risk of developing certain cancers and neurodegenerative diseases like Alzheimer’s disease. Those who study the traditional Japanese diet believe that high green consumption may play an important role in the population’s health and longevity.
Dive into the world of Japanese cuisine with seaweed. This versatile marine plant is a common ingredient in Japanese dishes and is packed with nutrients and health benefits. Seaweed is often eaten raw, in soups, as a salad or side dish, over rice, and dried as garnish or condiment. The marine plant is loaded with nutrients and health benefits.It’s the best natural source of iodine, an essential mineral that supports hormone production and metabolism. A single serving of seaweed contains a full day’s recommended iodine. Additionally, some research suggests that eating seaweed promotes heart and gut health and boosts immune function. Adding the ingredient to your diet may help lower blood pressure and maintain healthy blood sugar.
Ginger, oh ginger! This spicy and aromatic root is not only a delicious addition to your meals, but it’s also packed with all sorts of health benefits. Ginger is a common ingredient in a traditional Japanese diet. Pickled ginger, or gari, is made by preserving thin slices of ginger in a mix of vinegar, sugar, and salt. The result is a sweet, sour, and slightly spicy dish that cleans the palate and has antimicrobial properties. Gari may be eaten at the beginning or end of the meal or between dishes. Research suggests that ginger in any form can help fight bacterial infections. Ginger is naturally anti-inflammatory, which helps prevent inflammation-related conditions. The root contains antioxidants that protect cells and may support brain function and promote healthy aging. Ginger also helps aid digestion, reduces gas, and prevents nausea.
Umeboshi is a type of pickled plum that is popular in Japanese cuisine. It has a sour and salty flavor and is often used as a condiment or added to rice dishes. Umeboshi is high in antioxidants, which are substances that can help protect your cells from damage caused by free radicals. Free radicals are unstable molecules that can be harmful to your body and are believed to contribute to the development of certain chronic diseases. In addition to its high antioxidant content, umeboshi is also believed to have a number of other health benefits. Some research suggests that it may help to improve digestion, boost the immune system, and reduce the risk of certain types of cancer. It is also thought to have anti-inflammatory effects and may help to reduce the severity of certain types of headaches.
