In the last couple of decades, perception of the food and its validation went through many different perspectives. It was taken as a primary need for human and nobody has given any attention to it. In modern age we live in, food is becoming a custom, part of tradition and culture bringing other experiences along. When the concept of material heritage has developed sufficiently, many factors, or categories of everyday life, are added to the lists of humanity heritage. After all, only human is the one deciding what is good for its existence and what needs to be preserved for future times. The characteristic of Istrian and northern Dalmatian gastronomy is the so-called – Mediterranean diet. The Mediterranean diet helps to build at least one part of the image of the identity of the whole one region. It is important to emphasize that the common heritage of the Mediterranean countries is the foundation upon which they have grown, the climate, the sea and the coast, the sun, the soil, the animals and plants that live and manage to survive in that territory and all other common characteristics. It is even more important to emphasize what differentiates from each other, because that is what truly reflects the core of a country, its customs and identities. So each country got one part of the same foundation and made something different from it. Like multiple sequels to the same novel - it’s based on the same characters, but the plot is different from sequel to sequel. Significant points of identity, or characteristics of life on the eastern Adriatic coast, are definitely olive growing and olive oil production, viticulture and wine production, fishing and livestock. All these activities are known and present in the eastern Adriatic area since antiquity, and some even longer. Today, they are recognized as heritage and much work is being done to promote and protect them. Almost every city or municipality associates a food product, food item or specific dish with its identity or history. These are all small moments in the opacity of seemingly simple, but in fact very wide andvaried Mediterranean cuisines, although they are large for the community itself. Most of these places have also created a manifestation, a celebration and honor the gastronomic part of their heritage. The Mediterranean indigenous diet is rightly included in the heritage of humanity. It is so widespread and widely recognized and represented, associated with health, recommended by many nutritionists, doctors and other professionals as a diet that would have a very beneficial effect on the human body. It has so much worldwide attention that it can truly be considered the heritage of all humanity.
