The History Of Tuna In Nutrition

It is known that 2000 years ago the Phoenicians caught tuna in the Mediterranean Sea. The ancient Greeks, observing the hunt, named the fish thynō, which means “throw” or “throw”. Aristotle described this fish in the History of Animals, and Pliny recommended tuna dishes for the treatment of ulcers.

Attitudes towards tuna varied. In feudal Japan, it was said that “even cats despise him.” Most likely, the reason for the rejection was the risk of food poisoning. Warm-blooded fish spoiled rather quickly, so before the invention of refrigeration, they were often thrown away.

The Japanese now regard Bluefin tuna as the most valuable fish in the world. They carve it with the same reverence as the French prepare truffle dishes. In the middle of the last century, the annual tuna catch reached up to 1 million tons. After the appearance of “purse” nets, the global fishery increased to 4 million tons. As a result, some species of tuna are on the verge of extinction.
