Japan has topped the WHO’s lists of countries with the highest life expectancy for decades, and a large part of this is likely due to the Japanese cuisine and the diet. But what is it that they eat that is so healthy?

The traditional Japanese diet involves a lot of rice, fish and mear, along with cooked and pickled vegetables. There are also lots of fermented and smoked foods, products made from soybeans, dairy, and vegetables (from both land and sea) such as edamame and seaweed. The Japanese are also fans of matcha tea.

There is great emphasis on the seasonality of food (for example, enjoying bamboo shoots in the spring, and chestnuts in the autumn), which means that there isn’t much preservation involved, traditionally.

japanese cuisine set mealAnother important factor is how the food is served. Rather than one large serving of each dish, they are traditionally served in small bowls of the many small side dishes (known as okazu) and accompanied by a single serving of rice (known as gohan). Along with this, there may also be clear or miso soup and pickles (called tsukemono).

Various cooking techniques are used for the okazu, such as grilling, boiled, steamed, deep-fried, dressed in vinegar, or even eaten raw. This means that the food is prepared with little oil (apart from deep-fried foods)

So is diet responsible for Japan’s impressive health and longevity? Let’s take a look.

Popular and Healthy Japanese Dishes You Can Try

Sushi

Sushi rolls composition japanese cuisine

Sushi is made with vinegared sushi rice (shari) topped, or mixed with, seafood or vegetables. There are various forms of this popular Japanese dish. The various ingredients may be placed on top of a block of rice, or (as is perhaps more famous) rolled inside it. Sushi is often served with pickled ginger (gari), wasabi, and soy sauce. Sheets of black seaweed wrappers (called nori) may also be used as a wrap.

With the main ingredients being rice, fish, and vegetables, sushi is high in protein, carbohydrates, vitamins, and minerals, as are its accompaniments such as gari and nori. Fish is also rich in omega-3 fatty acids which have a range of beneficial properties, especially to cardiovascular health. While there are some health risks when it comes to the types of sushi containing raw fish, particularly parasitic infections, these can be greatly reduced by practices such as super-freezing.

Mochi

Daifuku mochiThis Japanese rice cake is made of short-grain glutinous rice (mochigome) that is pounded into paste and moulded into shapes along with water, sugar and cornstarch. Mochi is eaten year-round but is traditionally associated with the Japanese New Year. It comes in many flavours and with filings (when it becomes known as daifuku) such as sweetened red bean paste (anko), white bean paste (shiro an), or plums.

Though mochi is high in carbohydrates, proteins, and in calories, it is gluten- and cholesterol-free, as it is made from rice flour. Additionally, it was traditionally consumed it during the winter to increase stamina, and taken as a packed food as it is easy to carry.

Miso Soup

Miso soup is said to contain various essential bacteria that promote good health, and also low in calories, but is filling due to the high protein content.

Edamame

Shiruko is usually served with mochor rice flour dumplings.

This dessert is usually enjoyed warm in the winter. Red beans are an excellent source of fibre and proteins while remaining low in calories, so they fill you up and help slow down sugar absorption.

They are also an excellent source of calcium, potassium, and dietary fibre.

Hoshigaki
