The concept of canning, which was only recently, in the context of human history, able to continue and develop, completely altered the food context.
Canned tuna is among the most significant developments in this area because it allows for the consumption of fish and other similar products even after years of incubation. But who should avoid eating tuna in a can?
Even if the quantity of specimens is being watched owing to indiscriminate and illegal fishing, tuna, in its numerous subcategories and varieties, represents a widespread species in excellent numbers in practically every type of climate and mild condition.
The tuna lacks a swim bladder, a device that helps the animal maintain its “height” in the water, therefore it is “condemned” to swimming for the rest of its life.
It is also a large-muscled animal for this reason, which makes it perfect for canning fish pieces and muscle after they have been cleaned, boiled in water, drained, and given other treatments to increase its consistency and preservation, including salting.
In particular, theeb has been the target of a “defamatory” effort.
However, certain people—for example, those who use antitubercular medications because the histamine content might rise to concerning levels in this regard—are incompatible with the eating of canned tuna. Due to the salt concentration, even people who have hypertension should refrain from consuming it regularly.
