Tuna is a saltwater fish belonging to the tribe Thunnini, a subgroup of the family Scombridae. Thunnini contains 15 species across five genera, ranging in size from bullet tuna to Atlantic bluefin tuna. The bluefin averages 2m and is believed to live for up to 50 years.

  • keeps the heart healthy: The omega-3 fatty acids that are abundant in tuna have been proven to protect against vasoconstriction and against high cholesterol levels. Incidentally, whether fresh or canned hardly plays a role, both contain about the same amount of healthy fatty acids.
  • provides a lot of iron: Fresh tuna reminds a little of meat in taste and appearance, and indeed: the iron content of 1 milligram per 100 grams is comparable to that of, for example, light poultry.
  • Scores with proteins: with around 20 grams of protein per 100 grams, tuna is one of the stars of the protein suppliers. Therefore tuna is the perfect choice for fitness and muscle building.
  • is a miracle of vitamins: fresh tuna has an incredible 450 micrograms of vitamin A per 100 grams – only eels and caviar have more. For canned tuna (in oil) there are at least 370 micrograms of the vitamin, which is particularly important for good eyesight and healthy skin.
  • gives brain power: The polyunsaturated fatty acids in tuna supply neurotransmitters and nerve cells with the perfect “lubricant”. Studies show that this improves thinking and concentration skills as well as memory.
  • can contain harmful substances: The healthy fat in tuna often has a disadvantage: it often also stores harmful substances such as environmental toxins. Experts therefore recommend that health-conscious people prefer to use tuna from certified breeding or organic tuna.
  • CO2 balance: With an emission value of over 260 grams per 100 grams, the CO2 balance of tuna is bad. The CO2 values ​​are based on the calculations of the IFEU Institute for Energy and Environmental Research Heidelberg and were individually accounted for as “average food” for each food as sold in Germany. They take the production location, the production method, all associated transports, processing, packaging and storage into account. The emissions of all greenhouse gases such as B. Carbon dioxide (CO2), methane (CH4) and laughing gas (N2O) were taken into account and converted into CO2 equivalents. Simplified, however, is only referred to as CO2.
  • is threatened with extinction: tuna is one of the fish threatened with extinction. So you should rarely and consciously enjoy it.
