• Salts of heavy metals were often found in the meat of tuna or salmon. In particular, lead, cadmium, arsenic and even strontium. These substances are dangerous to human health.
• The older the fish, the more toxic elements it contains. And on the packages in the store the age of the seafood is not written.
• Rare fish farms can boast of the quality of their products. To increase mass, biochemical additives are used. Often sick individuals are also sold.

The nutritional value

Vitamins and minerals

Let's look at the vitamin and mineral composition of fish using low-calorie navaga as an example.

Most fish caught in the open sea contain toxic waste that is present in the water. And the older the fish, the more waste it will accumulate.

Heavy metals accumulate in the organs and tissues of marine life, and poisoned water injures their outer coverings. Fish have curvature of the spine, lack of fins, cirrhosis of the liver, ulcers on the integument, and kidney stones. Heavy metals rush into the water especially intensively in the spring, when the snow melts.

Expert commission for biological research clean water, flora and fauna of the world's largest freshwater lake system has concluded that eating fish from the system has negative health effects. Scientists have proven that mercury contained in fish causes infertility in both men and women. Mercury causes cellular or genetic damage to the ovaries.

Scientists emphasize that much more toxic elements are concentrated in predatory fish, since the food chain ends there. The results of the analyzes conducted by the researchers showed that various organs fish - scales, muscles, bones, liver, genitals, intestines, contain off-scale doses of zinc, copper, lead, cadmium, nickel, arsenic, chromium, as well as cesium-137 and strontium-90.

Chlorinated hydrocarbons and polychlorinated biphenyls, which are harmful to humans and accumulate in fats, are often present in large quantities in fatty varieties fish (salmon, salmon, trout).

It is known that when storing fish, fats quickly oxidize under the influence of air, light and elevated temperature.

From frequent consumption of omega-3 fatty acids to people who have problems with the pancreas, an overdose of omega-3 threatens serious problems with the adrenal glands.

Phosphorus from fish is poorly absorbed because it contains too little calcium and magnesium. Scientists know that calcium and phosphorus are fully absorbed only when the product you eat contains calcium, phosphorus, and magnesium in an organic, balanced form.

Benefit

The most valuable in fish are fatty acid omega-3 and omega-6 (eicosapentaenoic (EPA) and docosahexaenoic (DHA) acids), not found in other products (fish oil).

The mucus on the surface of the skin should be colorless, without any foreign odors. When pressing on the scales, there should be no dents left - the fish must be elastic.

At home, the freshness of ungutted fish can be determined by placing it entirely in a bucket of water - fresh fish will sink to the bottom, and stale fish will certainly float to the surface. For deeper and detailed study a special laboratory and specialists will be required.

A lot of fascinating and educational material has been written about the benefits of fish for the human body and for the male body, in particular. But can the elements that make up the main sea and river product cause harm? men's health, you will learn about this by reading our article.

For example, pike perch meat, which is distinguished by its taste qualities, rich in protein and taurine.

Perch lives in reservoirs only with clean water, so its meat can be confidently called an environmentally friendly product.
