What the centenarians in the Blue Zones tell us about healthy ageing.

The Blue Zones are regions in different parts of the world where people enjoy an exceptionally high life expectancy. These areas were first researched by journalist Dan Buettner, who studied the lifestyle and eating habits of the inhabitants to identify the factors that contribute to their long and healthy lives.

But what are the secrets of healthy ageing? In this blog article, we will take a closer look at the lifestyle habits and nutritional factors in the Blue Zones and find out whether there are complementary measures that can contribute to longevity.

The Blue Zones and their longevity secrets

  1. Okinawa, Japan: The importance of nutrition: The inhabitants of Okinawa are longevity champions and have one of the highest life expectancies in the world. Their diet is characterized by fresh vegetables, lean fish and tofu. They eat in moderation, which leads to a lower calorie intake, which has a positive effect on health. Green tea, which is rich in antioxidants, is also consumed regularly. This diet is low in processed foods, which leads to a lower risk of chronic diseases.
  2. Sardinia, Italy: Social ties and movement: Sardinia is known for its strong community and social ties. People in this region share their worries and joys with friends and family. This close social interaction can reduce stress and promote general well-being. The inhabitants of Sardinia are also physically active, be it working on the land or taking a daily walk.
  3. Loma Linda, California: Plant-based diet and spirituality: The inhabitants of Loma Linda, a town in California, are characterized by their plant-based diet. Many are vegetarians or vegans and consume little meat. In addition, spirituality plays an important role in the lives of people in this region, helping them to cope with stress and maintain a positive outlook on life. This also leads to their famous “longevity” or healthy longevity.
  4. Ikaria, Greece: Mediterranean diet and tranquillity: The inhabitants of Ikaria, a Greek island, follow the famous Mediterranean diet. They eat plenty of vegetables, olive oil and fish, which is rich in omega-3 fatty acids. Regular rest in the form of a midday nap, known as a “siesta”, can reduce stress, promote mental health and also longevity.
  5. Nicoya Peninsula, Costa Rica: Healthy eating and exercise: A balanced diet plays a crucial role on the Nicoya Peninsula. The residents consume a lot of fresh fruit and vegetables. They are also physically active, whether through housework or gardening. This promotes their fitness and contributes to a healthy lifestyle that supports healthy longevity.

Lifestyle habits of the Blue Zones

Social ties and community

Strong social ties and communities are of great importance in the Blue Zones. People spend time with their families, friends and neighbors, which promotes social support and a sense of belonging. This helps to reduce stress and improve mental health. Social isolation is rare in these communities, which has a positive effect on life expectancy and longevity.

Active lifestyle

The people in the Blue Zones lead an active lifestyle. They walk, garden, farm and have no modern conveniences such as elevators or automobile transportation. This regular physical activity is a natural part of their everyday life and promotes heart and muscle health.

Stress management

Stress is less present in the Blue Zones than in many other parts of the world. This is often due to the relaxed attitude of the residents, the strong social ties and the traditional relaxation methods such as meditation and prayer. All of this contributes to longevity.

Sense and purpose

People in the Blue Zones often have a strong sense of meaning and purpose in their lives. They are actively involved in their communities and are committed to various activities even in old age. This sense of purpose (Japanese: ikigai) can have a positive effect on mental health and longevity.

Nutritional factors of the Blue Zones

Plant-based diet

A plant-based diet plays a central role in the Blue Zones. People mainly consume fruit, vegetables, pulses and wholegrain products. Meat, especially red meat, is eaten in small quantities. Instead, fish and lean poultry are on the menu. The plant-based diet in the Blue Zones is rich in fiber, antioxidants and important nutrients that contribute to overall health.

Moderate calorie consumption

In many Blue Zones, people eat until they are full, but not to excess. Excessive calorie intake is rare in these regions, resulting in healthy body weights and lower rates of obesity.

Moderate alcohol consumption

Some Blue Zones have integrated moderate alcohol consumption in the form of wine into their diet. Wine, especially red wine, contains antioxidants that can protect the cardiovascular system. However, it is important to note that alcohol consumption should be in moderation to maximize the health benefits.

Reduced sugar consumption

People in the Blue Zones consume little refined sugar and processed food. Instead, they eat natural, unprocessed food. This helps to reduce inflammation and lower the risk of chronic diseases.

Food supplements for your Blue Zones lifestyle

While people in the Blue Zones rely mainly on natural foods, there are some supplements that can be considered if you want to follow their dietary style for longevity. The decisive factor here is, of course, that the supplements are not synthetic, but come entirely from natural, purely plant-based sources, such as the supplements from Ogaenics.

Omega-3 fatty acids

In the Blue Zones, where fish plays an important role in the diet, the consumption of omega-3 fatty acids is high. Omega-3 fatty acids can have an anti-inflammatory effect and protect the cardiovascular system. If fish is not a regular part of your diet, omega-3 supplements can be a useful addition (e.g. Oilalala Skin Omega Complex from Ogaenics)


Gut health plays an important role in the immune system and general health. In some Blue Zones, fermented foods are an important part of the diet, promoting intestinal health. For people who do not regularly consume fermented foods, probiotics can help to support the intestinal flora(e.g. Love Your Gut Dialy Biotic Complex from Ogaenics).

Vitamin D

The Blue Zones are all sun-drenched. This promotes the body’s own vitamin D production. However, in regions with low levels of sunlight such as Germany, vitamin D deficiency can easily occur. Vitamin D is important for bone health, the immune system, the hormone system and proper cell division. It therefore plays a fundamental role in your vitality into old age. Taking vitamin D supplements is therefore recommended (e.g. Hello Sunshine Plant-Based Vitamin D3 plus K2 from Ogaenics) .

Vitamin B12

Vitamin B12 is mainly found in animal foods. In regions with a strictly plant-based diet, such as vegans, vitamin B12 deficiency can occur. Vitamin B12 supplements are a possible solution to remedy this deficiency (e.g. Green Energy Plant-Based Vitamin B12 from Ogaenics).
