Is Japanese Food the Healthiest in the World?
Known as the Hawa’ii of Japan, you could mistake the Okinawa islands for the ink that dripped onto the map after the cartographer finished drawing in the mainland.
Despite their size, this spattering of islands in the South China Sea are truly remarkable.
Not for the crystal clear waters of the coastline, or stunning scenery, but because out of anywhere in the world, Okinawa has the most citizens per 100,000 who have celebrated their hundredth birthday.
Scientists are still scratching their heads as to why Okinawan’s live for so long. Some argue it’s the combination of a slow pace of life, regular physical activity and tightly knit community. But above all else, experts have pointed to their diet.
This Okinawan diet plan may seem, how should we say this… limited, but these old timers actually share a lot of the same eating habits as the rest of Japan.
As the country with the lowest levels of obesity and nutrient deficiency out of anywhere in the world, we’re left wondering - what makes the Japanese diet so healthy, and has Japan got the best diet in the world?
Japan is famed for its long history of fermentation, and many of their most commonly used fermented goods have been exported around the globe.
Miso and Shoyu (soy sauce) are the classic examples both hailing from the humble soybean. These umami-rich ingredients are two of the pillars of Japan's flavour profile, but they are far from the only fermented products you are likely to find there.
Pickled vegetables known as Tsukemono are a classic accompaniment to any dish, and with the local varieties of daikons, turnips and carrots they bring a tangy punch with their boatload of nutrients.
There are also slightly more niche examples of fermentation like Umeboshi (eye-wateringly sour fermented plums) and Natto (fermented soybeans that resemble rice krispies covered in sticky spider webs), and while these last two might take a little longer to become a mainstay in Western cupboards, they are just another example of how omnipresent fermented delicacies are.
But these foods don’t just add to the bounty of flavours on offer in Japan, they also add to the healthy bacteria in the body.
Fermented foods are known to promote weight loss, healthier digestion and boost the immune system, and the Japanese are reaping the benefits of their macrobiotic diet.
Japanese Diet of Fish
More and more Japanese families are eating meat as part of their regular diet (and on the high holidays), but as late as 1939, a typical person in Japan ate an average 0.1 ounces of meat per day!
Times have changed, but modern foods like Wagyu beef and chicken katsu still have a way to go to knock seafood of it’s perch.
Fish has been a huge part of the Japanese diet for centuries and the classic seasonal cuisine of the country known as ‘Washoku’ relies heavily on seafood as the main source of protein.
Far from sushi being it’s only form, you are likely to see fish served grilled, steamed or even dried - that being said it’s unsurprising Japan is the fourth largest consumer of fish in the world!
If you compare Japan to the United States for instance, fish makes up over a third of all animal protein eaten by the Japanese, whereas it makes up only 6% eaten by US carnivores.
While the jury is still out over the benefits of a meat heavy diet, the verdict is in for the power of fish with all its oily omega 3 goodness.
