5 Healthy Eating Habit Tips: Achieving Longevity Through a Blue Zone Diet

Have you heard of the “Blue Zones”? They are longevity hot spots found across the globe where people are most likely to live long and healthy lives. The term was coined by National Geographic Fellow, Dan Buettner, and the locations include Ikaria, Greece; Sardinia, Italy; Okinawa, Japan; the Nicoya Peninsula in Costa Rica; and the Seventh-day Adventist population in Loma Linda, California.

Considering most people are looking to live long and healthy lives, many researchers have studied these populations to uncover their secrets. What they found is that a handful of lifestyle behaviors were consistent across all Blue Zone populations. People living in these longevity hot spots were all likely to do the following: not smoke, be active, have strong social/community support, manage stress, and find purpose in life. In addition, they all tend to eat a similar diet, such as a Blue Zone diet.

Here are the top five diet tips from the world’s healthiest and longest-living populations:


Plant-based meals are consistent across all Blue Zone diet locations, where roughly 90–100% of calories come from plants. Diets rich in plants provide a wide variety of disease-fighting and life-extending nutrients, such as antioxidants, polyphenols, and anti-inflammatory compounds. Some of the best life-extending foods include dark leafy greens, vegetables, berries, whole grains, sweet potatoes, corn tortillas, nuts, and fruit. But the food most associated with a long and healthy life is beans.


Although shunned by low-carb/paleo diets, beans are a staple food in the Blue Zone diet. In the Mediterranean, meals often feature fava beans, garbanzo beans, and lentils. Black beans reign supreme in Costa Rica, Okinawans eat mostly soybeans (including tofu), and in Loma Linda, it’s all of the above. Beans appear to be the one food most associated with healthy aging, so it’s no surprise they’re found in every Blue Zone diet. ₁ Because they’re a good source of protein, beans are a great food to replace meat. Add some garbanzo beans to your salad, opt for the black bean burger, switch to a tofu stir-fry, or make a pot of bean and vegetable soup.


Plain old water is the best beverage option when we’re thirsty, but other beverages can add a nutrient boost to our diet. Coffee, tea (especially green tea), and red wine all contain polyphenols, which are a group of compounds that appear to ward off degenerative diseases, such as cardiovascular disease, dementia, and many types of cancer. These beverages are featured frequently in long-term lifestyle changes. Green tea is common in Okinawa, coffee in Greece and Costa Rica, and red wine is a favorite in the Mediterranean regions. Although these beverages can be part of a healthy longevity diet, they don’t have to be. The Seventh-day Adventists in Loma Linda, who tend to eat vegetarian/vegan for biblical reasons, also tend to abstain from alcohol and caffeine. However, one thing these populations all have in common is that they avoid sugary beverages and cow’s milk, and rarely drink alcohol in excess.


In Okinawa, Japan, where women boast the longest life expectancies in the world (90 years old), there’s a cultural practice of not overeating. Elders on the island will often state the phrase, “hara hachi bu” before a meal, which is a Confucian teaching that instructs people to eat until they are 80% full. This doesn’t mean that they try and calculate exactly how full they feel with each bite, but it’s a reminder to eat mindfully and not overindulge. This practice may help people maintain a healthy body weight—a characteristic associated with better health and longevity—by keeping calorie intake within an appropriate range. The traditional Okinawan diet, which was 96% plant-based and heavily featured purple Okinawan sweet potatoes, most likely played a significant role in their long life expectancies as well. ₂


Another common feature among these healthy, long-living populations is shared meals. One of the best predictors of happiness is strong social connection, and having shared, family-style meals is a great way to build these connections. This may not be appropriate during our current pandemic, but it can still be accommodated by practicing social distancing, practicing good hand hygiene, eating outside, or simply having sit-down meals with immediate family members. It doesn’t have to be every meal but aim for one per day or at least a few per week.


Many people scoff at the idea of living until they’re 90 or 100 years old because we’ve associated aging with a decline in quality of life. But many of these long-living populations don’t just have a long life expectancy, they have a long health expectancy as well. In other words, they’re living longer and staying in relatively good health in their later years. If you could still garden, travel, socialize with friends/family, go to the movies, have sex, do crossword puzzles, or do other activities you currently enjoy with limited aches and pains, wouldn’t you want to live longer? By practicing these healthy eating habits and lifestyle behaviors we can add years to our lives, and life to our years.
