The island of Okinawa in Japan, just north of Taiwan, has long been a hot spot for the secrets to longevity. It is unrivaled for its health, spirituality and connection to mind and body. In fact, Okinawa has some of the highest number of centenarians (those who live past 100) in the world at about 50 per 100,000 compared to 5-10 per 100,000 in the USA. These aren’t your average old folks either.

Here in the West, we associate old age with misery, joint pain, dementia and nursing homes, but in Okinawa, the centenarians are happy and surprisingly independent. Diseases like Parkinson’s, Alzheimer’s, autism, cancer, diabetes and heart disease are incredibly rare to say the least! Yet when an Okinawan is removed from his or her society and rituals and adopts an American or Western lifestyle, their age limits begin to parallel those of the citizens of the United States. What exactly is their secret? Although genes do play a role, it seems lifestyle is the biggest contributor. In 2000, the Okinawa Centenarian Study published some fascinating facts on longevity:

 1. Plant centered diet:

Okinawa is a beautiful tropical island (which helps anyone’s mood), but there is a bigger secret to their success. Because the plants are closer to the equator where the sun’s damage may be greater, they protect themselves by producing higher amounts of phytochemicals and antioxidants to stay alive. These nutrients not only protect the plants from the sun’s rays, but from animal/insect consumption too. Those phytochemicals are what correct free radicals and eliminate inflammation from our bodies! Okinawans eat up to 10 servings of fruits and veggies a day- all organic!


2. 20% or Less Animal Protein

In Okinawa, the population grows their own food. Their diet is 80% plant based with the 20% reserved for fish, eggs, and occasionally, pork or a larger animal for a ceremony. All meat they eat is raised on the land, free of antibiotics, hormones and cruelty that exists in western culture in factory farms.

The 80/20 rule is exactly how I eat. 80% of my diet consists of plants ranging from greens, to nuts and seeds, to root vegetables. 20% of the time I include fish, organic ghee, organic pastured eggs (local farm), raw milk/kefir (local farm), and occasional grass-fed meats/organs.


3. High Flavanoids (natural estrogenic compounds from food) & Good Fats

They eat grains, root vegetables, sweet potatoes, leafy greens and a ton of non-gmo fermented soy (90% is GMO in the USA). Examples include miso and tofu, which are both excellent for the liver and menopause. They contain natural estrogenic compounds that ease the symptoms of menopause (women of Okinawa experience menopause naturally with fewer complications). Miso and tofu are fermented forms of soy which are safe to eat since the trypsin inhibitors have been deactivated. Never eat soy that has not been properly fermented, because there are several dangers at play when the anti-nutrients are not deactivated.

Another important ‘health secret’ in the Okinawa diet is bitter gourd or goya. As the name implies, this is a very bitter melon!


It contains B vitamins, vitamin C, calcium, magnesium, zinc, phosphorus, iron and beta carotene. It also contains a phytonutrient called charantin and an insulin mimicking compound called polypeptide P that induces lower blood sugar and could be a remedy for diabetics.

Another reason they go through menopause and hormonal changes so easily is because they eat sweet potatoes, a superfood for the reproductive system.

See my post: A $1 Breakfast with a Wealth of Benefits

In the post above, I said you should eat a sweet potato every morning – and it turns out this incredible culture agrees with me! All Okinawans aged 100 or more who are alive today, were born between 1903 and 1914. During the first third of their lives, roughly before 1940, the vast majority of the calories they consumed — more than 60 percent — came from one food: the imo, or Japanese sweet potato. The Japanese potato is the purple/yellow variety I talked about, which is a relative of our orange sweet potato.

4. Caloric Restriction:

They practice a technique called Hara Hachi Bu, where they do not overeat. It translate to 8 parts out of 10, meaning they stop eating when they are 80% full.

Caloric restriction has been a debatable topic but studies have shown that restriction, without malnutrition, can produce measurable benefits and potential longevity. Caloric restriction also activates autophagy, which is the process by which older, dead cells are gobbled and cleaned up by other cells to keep the body running at tip top shape. If the body is inefficient at removing old debris, then this buildup can lead to neurodegenerative and cardiac diseases.



Other studies point to “hormesis,” which means to induce benefit from low intensity biological stressors. This theory proposes that a calorie restricted diet excites the immune system and heightens the defensive state by inducing small amounts of stress, which lead to turning on longevity genes through epigenetics (certain genes are turned off and on based on nutrition, environment, thoughts, etc).

5. Daily exercise:

They practice daily exercise that is not only beneficial for the body, but the mind too. You know how wonderful it feels to finish a challenging or relaxing yoga class? Imagine doing that every day in a slower paced, island environment. The majority practice Tai Chi, karate, gardening, dance, yoga or martial arts which are known to connect mind and body in a more spiritual process. Also, no one smokes! They also have little osteoporosis (no they don’t drink a lot of milk which does not stop osteoporosis) because they eat more plants which are chock full of calcium! They then activate vitamin D and overall bone health by spending time outdoors in the sun.

 6. Positive attitude:

When polled, the Okinawans consistently scored higher in the ability to handle stressful situations as well as overall outlook on life. On the island they enjoy a slower paced life and close, supportive networks. Lab results reveal low levels of homocysteine, an inflammatory amino acid present in those with heart disease. Okinawans have a 80% lower risk of heart attack!


7. Close knit community groups:

We are social beings who need love and support from friends and loved ones. Up to 80% of Okinawa’s elderly live alone independently or with a spouse, however they never give up their connection to community centers or elder day cares where they engage in games, sports or exercise together. There is a name for these social groups and they are called moai groups. In Okinawa, growing old is looked at respectfully and the elders still help to run the community. There is always family visiting as life is slower paced. There are local festivals, gardening activities and healing herbs brought to friends and dances for all to attend to continually heal the body and soul.

 8. Find your “ikigai:”

Ikigai means “your purpose.” Retirement is a foreign concept in Okinawa. Their belief is make life worth living no matter how old you are. You help others and continue to always look for a renewed mission.


 9. Cultivate spirituality:

Spirituality, but not religion, is a major part of life in Okinawa. There are morning rituals, meditation groups and a continued sense of belonging to a group that works collectively to achieve something bigger than them. They do not shy away from music or dancing as they believe this awakens the soul. The natives play Okinawan instruments like a traditional banjo and gather for community celebrations often. Women in Okinawa are noro (priestesses) or yuta (female shaman).

10. Eastern and western medical approaches:

Unlike the mindset in the West where there is a pill for every symptom and hard work to achieve health is often shunned, the Okinawans combine both aspects to achieve overall health. The employ shamanistic healing practices, spirituality and some Western outlooks. They believe in the vitality and health of the people and their villages. Particularly, the older women play an active role as the religious leaders and spiritual shaman in the villages. Ancient herbs like the ones used in Ayurveda and traditional Chinese medicine are used in daily life. In fact, turmeric is consumed in large quantities (mostly in tea) and is revered for its antioxidant and detoxifying effects on the liver.

We can all learn some lifestyle lessons from the wise and gentle people of Okinawa, Japan!

Wow this is beautiful. Such a simple, yet powerful lifestyle. Imagine if we all lived by these facts. I believe deep down we all know these ‘secrets’ intuitively to be happy and healthy. Unfortunately society and the system we are caught in blocks our intuition (I believe…) or we are too scared to be truly happy and healthy.. so sad! Sorry, i need to be more positive!! Keep up the great work! I would love to read more 🙂


Can you please offer any natural remedies for sebaceous hyperplasia?


Love this post thank you for sharing!! I love how you incorporate all of these different points and it is so relatable and doable in our own lives!


Thank you for the post! I live on this blog! It keeps me informed and motivated.


The article speaks of turmeric, as spice used in teas- in their daily diet. Do you have any recommendations/ suggestions for recipes? I drink a lot of tea, but have not had turmeric in my tea, yet. But would like to give it a try, given the great health benefit mentioned in this article. Thanks for sharing!



Indian cuisine tends to use tumeric – there’s lots of great recipes if you do a search 🙂

Tumeric tea is also great! You’ll find lots of great recipes if you search for golden milk recipes or tumeric tea. Look for ones that include some kind of fat and/or pepper as that increases your body’s absorption of the curcumin (the main active component in tumeric). Enjoy!
