Imagine waking up to the gentle warmth of the sun, the soothing ocean breeze, and a community that radiates vitality regardless of age.
Welcome to Nicoya, Costa Rica—a tropical haven celebrated not only for its stunning landscapes but also for the remarkable longevity of its people.
Here, it's not uncommon to see individuals in their 90s and beyond, living with a remarkable energy that seems almost timeless.
But what’s their secret?
The answer lies, in part, within their traditional diet, which centers on the "three sisters"—a trio of simple yet powerful foods that may hold the key to a long, healthy life.
Could incorporating these foods into your own diet be the first step toward unlocking the secret to a longer, more vibrant life?

The Power of the "Three Sisters" in Nicoya's Diet
In Nicoya, beans, squash, and corn are more than just ingredients—they’re the heart and soul of their diet.
These foods are packed with nutrients that promote longevity and overall well-being.
Alongside other local staples like papayas, yams, and bananas, this plant-based approach provides a nutritional powerhouse that supports a long, vibrant life.
Corn: A Kernel of Nutritional Wealth
In Nicoya, corn is not just a staple—it's a symbol of cultural tradition and nutrition.
It’s commonly transformed into tortillas, and the soaking process, which includes wood ash, enhances the grain’s nutritional value.

Rich in fiber, particularly the kind that aids digestion, corn also boasts vital nutrients like vitamins B and C, magnesium, and potassium.
The antioxidants in yellow corn can even help protect eye health, making it a true superfood for longevity.

Beans: The Mighty Legumes
Beans are an essential part of Nicoya's diet. Packed with protein, fiber, and micronutrients, these legumes support heart health, regulate blood sugar, and help maintain muscle mass as we age.
Beans are also naturally low in fat, making them perfect for weight management.

Studies suggest that a modest increase in bean consumption could lower the risk of mortality, with some even linking a daily serving to a longer life.
As health expert Dan Buettner notes, a cup of beans a day could be a key to living a longer, healthier life.
Squash: The Superfood of the Tropics
Squash is an antioxidant-rich food that helps protect cells from damage, reduce inflammation, and lower the risk of age-related eye conditions.
Its anti-inflammatory properties, combined with its ability to regulate blood sugar levels, make it an ideal food for promoting longevity.
With its low calorie and fat content, squash is a fantastic addition to any diet aiming to support health in later years.

Affordable Nutrition for a Long Life
The beauty of the Nicoyan diet is that it’s both nutritious and affordable. Even outside Costa Rica, the "three sisters" are budget-friendly, proving that eating healthily doesn’t require spending a fortune.
By focusing on plant-based proteins and reducing reliance on meat and dairy, Nicoyans get all the nutrients they need without breaking the bank.
Eating for longevity can be simple, nutritious, and cost-effective!
More Than Just Food: The Nicoyan Way of Life
While the Nicoyan diet plays a crucial role in their longevity, it's not the only factor.
A strong sense of community, daily exposure to sunshine, and a balance of physical activity and relaxation all contribute to the region's high life expectancy.
A central aspect of their philosophy is having a "plan de vida," or a reason to live, which nurtures a sense of purpose and positivity throughout their lives.
