Why Do Japanese People Live So Long? An Overview of Factors Behind Their High Life Expectancy
There are a variety of interconnecting factors that contribute to the impressive life expectancy enjoyed by Japanese people. Here is a quick rundown of the key reasons why Japanese citizens live longer:
- Traditional Japanese diet full of fish, soy, vegetables, and green tea
- Low rates of obesity and overweight
- High intakes of omega-3 fatty acids
- Strong focus on prevention in healthcare
- High rates of physical activity and low rates of sedentary behavior
- Low smoking rates, especially among Japanese women
- Effective universal healthcare system with good access
- Higher sense of purpose and strong social ties
- Low levels of stress and emphasis on relaxation
- Use of public transport and active commuting
While genetics plays some role, it's largely the diet, lifestyle, healthcare access, and cultural attitudes in Japan that enable such long average life spans. The traditional Japanese diet and active lifestyle are particularly instrumental - let's explore them further.
The Traditional Japanese Diet: What They Eat to Live Longer
Diet is one of the biggest factors influencing longevity. The traditional Japanese diet is full of nutritious foods that protect against disease and support health into old age. Here are some of the key elements of the traditional Japanese diet that promote longevity:
Fish and Seafood
Fish like salmon and tuna deliver omega-3 fatty acids that reduce inflammation, protect the heart and brain, and lower rates of cancer. Miso soup made with fish stock is a staple Japanese breakfast. Seafood like squid and octopus are also common in Japan. Higher intakes of fish and seafood support brain health and reduce mortality from major diseases.
Soybeans and Soy Products
Soybeans are a staple of the Japanese diet. Soy foods like tofu and edamame are rich in protein and antioxidants. Soy may lower LDL cholesterol, improve cardiovascular health, and reduce the risk of breast and prostate cancer. Soybeans also contain genistein, an isoflavone with anti-inflammatory effects.
From spinach to mushrooms to seaweed, the Japanese diet is packed with different vegetables. They eat 14% more veggies than Americans. The vitamins, minerals, and antioxidants in vegetables reduce inflammation, lower blood pressure, and prevent cell damage. Dark leafy greens are especially healthy.
The Japanese drink green tea daily, which contains catechins, antioxidants that reduce heart disease and cancer risk. Green tea may also activate fat-burning metabolism. Sencha is the most popular green tea in Japan. Matcha green tea powder is used in tea ceremonies.
Rice is a staple grain and carbohydrate source. But Japanese people eat reasonable portion sizes of rice as part of balanced meals. Rice bran contains antioxidants like vitamin E to reduce cholesterol. Brown rice is healthier than white.
Fermented foods aid digestion and deliver probiotics. The Japanese eat foods like miso (fermented soybean paste), natto (fermented soybeans), pickled vegetables, and small amounts of fermented alcoholic beverages. Fermented foods support gut and immune health.
So the traditional Japanese diet comprised of fish, soy, veggies, tea, rice, and fermented foods provides the nutrients and antioxidants needed for a long and healthy life. But what about how Japanese people eat?
Why the Japanese Diet Enables Longevity
It's not just what Japanese people eat, but how they eat that influences longevity:
- Smaller portions - the Japanese believe in the term Hara Hachi Bu, eating until you are 80% full
- Mindful eating - they eat slowly and with intention
- Shared communal meals - mealtimes provide social connection
- Balance and variety - the Japanese diet is rich and balanced but with moderation
- Fresh, seasonal produce - they focus on local, seasonal ingredients
The traditional Japanese diet ticks all the boxes for healthy eating patterns linked to longevity. But diet is just one piece of the longevity puzzle...
Active Lifestyles Keep Japanese People Living Longer
The Japanese are also very physically active, which reduces mortality and prevents many age-related diseases. Here's how Japanese lifestyles promote longevity:
Walking and Public Transport
Only 1 in 10 Japanese people drive cars regularly. Most either use public transport or walk to where they need to go. Lots of walking means more daily physical activity. Public transport also involves walking to stations. Active commuting is linked to lower BMI and reduced heart disease risk.
The Japanese incorporate small breaks for exercise during the workday. Office workers may do light exercise like stretches during short breaks. Building activity into work routines increases total daily energy expenditure.
Group Exercise Classes
Japanese people frequently participate in community exercise classes, especially aqua aerobics and dance classes for seniors. Exercising in a social group makes exercise more engaging and fun.
Martial arts like karate and judo are popular in Japan. Martial arts improve strength, balance, and fitness - key for healthy aging. The mental focus also reduces stress.
Hiking in nature is a popular weekend pastime. The Japanese are motivated to stay active well into older age to enjoy hobbies like hiking. Being outdoors also encourages relaxation.
Hot Spring Bathing
Bathing in natural hot springs (onsen) is part of Japanese culture. Enjoying hot springs promotes relaxation and recovery from activity.
So between active transport, leisure-time exercise, martial arts, and other active hobbies, the Japanese population stays physically fit as they age. But beyond diet and exercise, what else enables their longevity?
Healthcare and Cultural Attitudes Support Long Life in Japan
While active lifestyles and eating patterns are major pieces of the puzzle, other factors like healthcare and cultural values help Japanese people live longer:
- Universal healthcare ensures access to preventive care and medical treatment
- Health exams and screening are proactively encouraged
- Japanese people view caring for elderly relatives as a responsibility
- Strong social ties and community connections prevent isolation
- Japanese culture values rest and relaxation
- Nature-focused pastimes like hot spring bathing reduce stress
- Lower income inequality means access to health-promoting resources
Healthcare focuses on prevention and early detection of disease - key for longevity. Japanese people also feel a sense of purpose by caring for parents and grandparents as they age. And the Japanese people's zen approach to relaxation and communal focus allows them to manage stress.
So in summary, the combination of a nutrient-dense traditional diet, active lifestyles, effective healthcare, and cultural values all enable Japanese citizens to live longer, healthier lives.
