Beluga (sturgeon) is found primarily in the seas of Iran. Beluga caviar is the most expensive and precious type of caviar in the world. Most often, this fish is sold frozen or smoked. The fish contains 6.7 percent and its caviar contains 25.9 percent protein.

Caviar consumption prevents depression and cardiovascular disease, as it has a very high concentration of omega-3 fatty acids. In countries, where beluga and caviar have a special place in people’s eating habits, the rate of depression is much lower than in other countries.

The omega-3 fatty acids in caviar prevents high blood cholesterol and subsequently prevents cardiovascular disease. In addition, caviar prevents the development of arthritis, gastrointestinal diseases and some types of cancer.

Caviar is also rich in iron, which is why it is also recommended for people with iron deficiency and anemia.
