Description
The intake of tuna is favorable to a balanced diet due to its contribution in protein, iron and niacin content.3 As a general rule, the amount of calories is higher in tuna packaged with oils than those that have been packaged “natural” (100 grams of canned tuna contain 285 calories, while the same amount of fresh tuna has 200 calories).3 In some countries such as Spain it is common to see cans of pickled tuna.
Some authors mention that despite the high omega-3 content of tuna, most of it is lost during processing and packaging.4 The most common ingredients are salt, monosodium glutamate, hydrolyzed protein.
Spices, garlic, aromatic herbs, etc. are sometimes added.
Sometimes it is acidified with lemon juice.
The excessive consumption of canned tuna is not advisable due to the contribution of purines (that the organism converts into uric acid).
This intake is not recommended for people suffering from hyperuricemia or gout.
The salt content has worried certain sectors of the population with “high blood pressure”, which is why low-salt variants have been marketed since the beginning of the 21st century.
The cholesterol content is not low (50 mg/100 g), but is not higher than that of other animal products.
However, the presence of fatty acids reduces its incidence.
