Black caviar is not only an expensive delicacy, but also a healthy product.

Harm and contraindications

However, given all the positive aspects of consuming caviar, you cannot consume it in unlimited quantities. Eggs contain a large amount of salt, which can disrupt the water-salt balance of the body and kidney function. It is better to consume the product in its pure form, as preservatives and other chemical additives can harm the body. Chronic kidney disease and individual intolerance are the reason for the ban on eating sturgeon eggs.

Imitated black caviar

This caviar is made from algae, so it contains a huge amount of iodine and bromine. They help the thyroid gland work. Alginic acid normalizes blood pressure and helps remove not only heavy metals, but also radiation from the body.

But with all this, you cannot eat it in large quantities, since imitation increases intestinal motility, which leads to diarrhea. Also, those who have hormonal imbalances should not eat such food, since iodine in this case will only further aggravate the problem.

It is also worth remembering that seaweed often provokes an allergic reaction, so you should be careful about its use.

Price for black caviar

The price may vary depending on the type, method of preparation and region of sale of the delicacy. The cost of the product in Astrakhan and St. Petersburg will differ by several rubles. In Moscow, caviar can be ordered online or purchased in grocery stores. When purchasing, keep an eye on the production date and the quality of the canned food packaging. Poor quality products can be harmful to your health. If you are interested in how much black caviar costs, look at the table below.

How to choose black caviar

For a long time, sturgeon eggs were mined in the Caspian Sea. Aquaculture enterprises have now been created that grow fish to produce black caviar. This reduces the load on the ecosystem and avoids killing fish. Give preference to Astrakhan, Vologda and Volgorechensk producers. High-quality grains should be whole, of the same size, silver-black or gray-brown in color.

The product should have an almost imperceptible odor. The best caviar has a rich taste with hints of nuts. There should be only a slight bitterness present. Sturgeon eggs are sold in glass and tin jars. To assess the quality of a delicacy in a glass container, look at the type of grains. To check the quality of the product in the tin, shake it. If the eggs are “dangling”, put the jar back in place. The product must be certified and have a CITES permit.
