Sardinians are six times more likely to reach 100 years old than Australians.
The women in Okinawa live longer than women anywhere else in the world.
And despite there being 10,000 kilometres between the two islands, they've discovered the same secret.
A secret combination of diet, exercise, and well-being that has unlocked remarkable longevity and quality of life.
What's the secret? Let's dig into it.
Sardinia, an Italian island in the Mediterranean, and Okinawa, a region in Japan, have captivated researchers and health enthusiasts alike with their exceptional longevity. Both regions boast some of the highest numbers of centenarians worldwide, offering invaluable insights into what contributes to a long and healthy life.
From robust community ties to traditional diets rich in nutrient-dense foods, the lifestyles of Sardinians and Okinawans illuminate the profound impact of cultural practices and environmental factors on human longevity.
Understanding the common attributes between the two allows us to learn and implement changes into our own lives and routines, promoting healthier, more fulfilling lives.
The Diet: Quality Over Quantity
In Okinawa and Sardinia, longevity starts with what’s on the plate. These regions thrive on diets rich in wholesome, unprocessed carbohydrates, contrasting with the current low-carb craze.
Okinawan meals are vibrant and diverse. The foundation is sweet potatoes, a powerhouse of nutrients and the primary source of carbohydrates. They also consume rice, tofu, and an array of vegetables like bitter melon and seaweed. Soy products, such as miso and natto, provide protein, while small portions of fish and pork add a meaty variety. Green tea and medicinal herbs are common beverages, emphasising their belief in food as medicine.
In Sardinia, the diet is equally nourishing and diverse. Whole grains like barley and wheat form the base. Beans and legumes, such as chickpeas and fava beans, provide essential protein. Fresh produce like tomatoes, zucchini, and eggplants are staples, often seasoned with olive oil. Dairy is prominent, with sheep’s milk cheese like pecorino being a favorite. Sardinians also enjoy a moderate amount of wine, known for its heart-health benefits, especially the local Cannonau wine, rich in antioxidants.
In comparison, a typical Australian diet, while enjoying a diverse array of foods and culinary styles, often involves more processed foods and refined sugars. The Okinawan and Sardinian diets focus on quality and balance, with locally grown produce making up the bulk of consumption. Both regions prioritise low processed food intake and high nutrient density.
Both also consume meat at a relatively lower percentage than most western diets.
By incorporating whole and unprocessed foods like those found in Okinawa and Sardinia, Australians can enhance their overall health and longevity. This means more sweet potatoes, legumes, whole grains, fresh vegetables, and moderate, quality proteins. The lessons from these blue zones are clear: eat simply, eat naturally, and savour the benefits of a life well-nourished.
The Power of Movement: Natural Activity
Physical activity in these longevity hotspots isn’t about strenuous workouts. Natural movement is integrated into everyday life, leading to high VO2max levels, a key indicator of cardiovascular health. Their secret? Keeping active seamlessly throughout their daily lives.
Okinawans tend to their gardens with care, growing many of the vegetables they eat. This daily gardening provides light exercise and movement, connecting them to the earth. They walk everywhere, whether it’s a stroll to a neighbour's house or a longer journey to town. Traditional martial arts like karate and tai chi are practiced regularly, keeping their bodies strong and their minds sharp. These activities, woven into their daily routine, mean the reliance on a gym program and workout regiment is not needed.
In Sardinia, the landscape shapes the lifestyle. Elderly shepherds climb rugged hillsides, tending to their flocks of sheep. This demanding work requires endurance and strength, and they walk miles each day through the beautiful, rocky terrain. Many Sardinians engage in manual labor such as farming, which involves planting, harvesting, and tending to crops. This physical work again naturally promotes strength and stamina. Their daily routines are a testament to hard work and simplicity, promoting a long, healthy life.
This is a stark contrast to Australia, where the rise in office jobs has resulted in physical activity and movement often centring around structured exercise routines in shorter, strenuous bursts.
Simple changes like walking more, getting out in the sun and gardening, or engaging in leisurely physical activities can add a large volume of enjoyable, low intensity cardio movement to your life.
How can we implement this into a Western lifestyle?
There’s much to learn from these regions. Here’s how you can incorporate similar practices into a modern western routine:
1. Embrace a Balanced Diet — Don’t shy away from carbs. Instead, focus on whole, unprocessed foods like fruits, vegetables, whole grains, and legumes. These nutrient-rich options support overall health and longevity. Consider:
- Meal prepping to ensure you have healthy options readily available
- Reducing the intake of processed foods and refined sugars
- Incorporating a variety of colourful vegetables into your meals for a wide range of nutrients
- Sourcing meat and vegetables locally & organically
2. Incorporate Natural Movement — Stay active throughout the day by integrating natural movements into your routine. Simple changes can make a big difference. Aim to:
- Walk more, take the stairs instead of the elevator
- Engage in activities like gardening or dancing
- Reduce sedentary time by setting reminders to stand up and move regularly, even if you have a desk job
3. Boost VO2max — Regular aerobic exercises such as running, cycling, or swimming can significantly enhance cardiovascular health. To simulate the constant, natural activity of Okinawa and Sardinia, consider incorporating modern cardio equipment into your routine!
While you needn't look farther than regular long walks, if you don't have hours to spend everyday, exercise equipment can be a great way to squeeze in the same benefits and increase VO2max in a busy schedule. Check out some of VERVE's favourite options:
