Sardinia, Italy – home to the world's longest-lived men. Okinawa, Japan – home to the world's longest-lived women.
With the average adult on the island consuming less than 2,000 calories of nutrient-rich food per day, the active lifestyle of Okinawans means this reasonable intake goes toward exercise and social time in the sun.
Though many Okinawans still saw themselves as Japanese and Okinawan, they began to question their underprivileged position in relation to mainland Japan.
That comes down to three main factors—diet, social practices, and genetics—explains Craig Willcox, a professor of public health and gerontology at Okinawa International University and a co-principal investigator of the Okinawa Centenarian Study, which has been investigating Okinawan longevity since 1975.
Body temperature is one of the most well known and important factors involved in lifespan; increased body temperature has been shown to negatively associate with longevity (i.e. earlier death) and conversely, lower body temperature is associated with increased longevity and reduced aging.
A Mediterranean diet remains one of the gold standards for living longer and more healthfully. This pattern is characterized by a high intake of fruits and vegetables; whole grains; pulses; healthful fats from nuts, olive oil, and avocado; and herbs and spices. It includes seafood a few times a week.
Inexplicably, the benefits of having children don't apply to paediatricians. Radiologists die at around 75 years, succumbing to conditions such as respiratory diseases or cancers, while OBGYNs live to about 82 years. Those who work in public health live the longest – up to almost 84 years.
These are natural changes that occur while aging. They cannot be stopped but it is possible to slow the rate of these processes. This can be done by changing one's lifestyle (diet, exercise, etc). The science of aging is not yet fully understood; therefore, it is difficult to determine an absolute limit of 200 years.
And although a human's average life expectancy has increased by decades in the last 100 years or so, our maximum life span hasn't shifted anywhere near as significantly. Many biologists think extending human life to that degree is currently impossible.
“Consuming excessive amounts of foods high in added sugars and refined carbohydrates such as white flour, foods high in saturated fat and/or trans fat and frequent consumption of red and processed meats have a negative effect on our health,” Murray said.
First of all, centenarians eat mostly unprocessed foods. They cook their meals with fresh plants and herbs from the garden or the forest. Animal protein intake is relatively low and vegetable and bean intake is high. They don't shy away from alcohol.
The country with the highest life expectancy at birth is Spain, with an average of 83.3 years, followed by Sweden (83.1 years), Luxembourg, and Italy (both 82.7 years). The lowest lifespan is predicted in Bulgaria (71.4 years), Romania (72.8 years), and Latvia (73.1 years).
Japanese life expectancy
This low mortality is mainly attributable to a low rate of obesity, low consumption of red meat, and high consumption of fish and plant foods such as soybeans and tea. In Japan, the obesity rate is low (4.8% for men and 3.7% for women).
At birth, AIAN and Black people had a shorter life expectancy (65.2 and 70.8 years, respectively) compared to White people (76.4) as of 2021, and AIAN, Hispanic, and Black people experienced larger declines in life expectancy than White people between 2019 and 2021.
As we age, our bodies become sensitive to cold temperatures. This is because of a decrease in the metabolic rate. Our aging bodies are not capable of generating enough heat to help maintain the normal temperature of 98.6 degree.
It can keep you looking younger.
Cold weather enhances the complexion and rejuvenates skin, Wong says. In a way, it slows down the aging process—think of cryotherapy spa treatments or splashing cold water on your face in the morning—and keeps skin tight, vibrant and radiant.

A traditional Okinawan breakfast usually consists of grains like rice and fermented soy beans. Miso soup is also a popular Okinawan breakfast meal that is accompanied with seafood or sometimes red meat. A typical Okinawan lunch or dinner are barely distinguishable.
Okinawans eat fish, meat, dairy, and grains like rice in much smaller amounts. Some examples of foods common to Okinawa diet include: Vegetables: orange sweet potato, purple sweet potato, seaweed, kelp, bamboo shoots, radish, bitter melon, cabbage, carrots, pumpkin, papaya, and mushrooms.
People who live in Okinawa, Japan have a wise strategy when it comes to maintaining a healthy weight. They call it “hara hachi bu”, which means to stop eating when you are 80% full. Studies show that cutting back on calories can lead to better heart health, longevity, and weight loss.
' But with common sense, healthy habits such as regular exercise, a healthy weight, avoiding red meat, not smoking, and managing stress, it can be 'the older you get, the healthier you've been,'” Perls says. The key to healthy aging is to engage fully in life—mentally, physically, and socially.
