Tuna fish...

  • ...is heart-healthy.
    The omega-3 fatty acids abundant in tuna have been proven to protect against vasoconstriction and high cholesterol levels. Tuna contains the same amount of fatty acids whether it is canned or fresh.
  • ...is a good source of iron.
    Tuna contains 1 milligram of iron per 100 gram serving, much more than other meats like poultry.
  • ...is rich in protein.
    Tuna is packed with valuable protein, containing around 20 grams per 100 gram serving.
  • ...is jam-packed with vitamins.
    Fresh tuna contains an incredible 450 micrograms of vitamin A per 100 gram serving, more than almost any other meat or fish. Canned tuna contains a bit less vitamin A, but still provides a substantial portion at 370 micrograms per 100 gram serving. Vitamin A supports eye and skin health, among other things.
  • ...powers the brain.
    The polyunsaturated fatty acids in tuna help lubricate neurotransmitters and nerve cells that connect to the brain, helping improve concentration and recall.
  • ...can contain harmful substances.
    The healthy fats in tuna often have a disadvantage: they can be depositories of harmful substances such as environmental toxins. Experts therefore recommend not eating tuna daily and only buying organic variety, which are raised with less toxins.
  • ...is threatened with extinction.
    Due to overfishing, tuna is at threat of extinction. Therefore make sure not to eat it too often, and to procure it from environmentally-conscious brands and sources when you can.
