There are few places in the world where people stay healthier and live longer. These areas are known as blue zones and are lands that seem to hold a secret to living longer.
The ones that put these countries inside a blue circle on the map (that's why they were named as blue areas) were the studies of two researchers, the Italian Gianni Pes and the Belgian demographer Michel Poulain, who started their research in Italy, Sardinia and more after they extended their search to the entire planet.
Në përfundim të studimit ata kanë identifikuar 5 zona blu: Ogliastra në Sardenjë, ishulli i Okinava në Japoni, Ishulli i Icaria në Greqi, qyteti i Loma Linda në Kaliforni dhe Gadishulli Nicoya në Kosta Rika.
Një nga elementët që shërbeu për të shpjeguar shëndetin e mirë dhe jetëgjatësinë e këtyre popullsive është padyshim dieta ushqimore.
Ja cilat janë disa nga karakteristikat e ditës së tyre:
Ogliastra në Sardenjë: Fasule, qumësht delesh dhe elb

In common with the diets of other blue zones, the Sardinian one has the use of vegetable proteins provided by beans, one of the most cultivated legumes on the island and used for soup and more. Sardinian casserole made with vegetables, chickpeas, beans, but also pasta, and sometimes pork becomes a recipe for longevity because, as longevity researcher Roberto Pili pointed out, it is a dish that is able to bring practically all of those 25-30 thousand molecules that our metabolism needs to function. Among the peculiarities of the Sardinian diet is the consumption of sheep's milk, which has better nutritional properties than cow's milk, being also useful in the prevention of cardiovascular diseases, but also in strengthening the bones. In Sardinian cuisine there is a use of cereals such as barley,
Icaria in Greece: Mediterranean plants and beans

Icaria is an island overlooking the Aegean Sea. It is one of the best countries of the Mediterranean diet, with lots of vegetables and small fish. In addition to olive oil, there are also Mediterranean herbs such as marjoram, which contains ursolic acid, capable of having a positive effect on memory, and mint, diuretic and anti-inflammatory. Another important food is green beans, a good source of protein.
Okinawa in Japan: Tofu, seaweed and turmeric

Okinawa is probably the best known of the blue areas. Among the characteristic foods of this people's diet is tofu, made from soybeans, which allows you to stock up on protein without eating meat. Turmeric is widely used, an antioxidant and anti-inflammatory, but also capable of counteracting Alzheimer's. Algae are widely used in addition to fish.
Loma Linda in California: dried fruit, avocado and oatmeal soup

Studies on residents of this area live an average of 10 years longer than the normal population and who eat an essentially vegetarian diet, low in sugar but rich in, for example, dried fruit. Consuming at least five times a week is one of the reasons for a higher average health and longevity. A must-have in the Adventist diet is slow-cooker oatmeal soup, which doesn't raise blood sugar, supplies iron, and B vitamins. On the California shopping list, salmon and avocado also appear, both valuable for good fats.
Nicoya Peninsula in Costa Rica: corn, pumpkins and bananas

In this blue field the traditional diet is based on one of the typical grains of South America, corn, nutritious, energetic and gluten-free. Another precious food is the pumpkin, which provides carotenoids, valuable antioxidants for health as well as carbohydrates that do not increase blood sugar. Then there are fresh fruits typical of the area, such as papayas, but also bananas, also a source of carbohydrates (which represent over 60% of the caloric intake of these populations).
