This fish contains proteins of high biological value and all the essential amino acids. According to a study published in the Annals of Nutrition & Metabolism, its intake helps to meet the daily requirements of these elements. It’s also meat with a good level of digestibility.

At the same time, tuna contains high amounts of omega-3 fatty acids, which are very important for neurological health. Especially for the baby’s developing brain.

There’s nothing wrong with including tuna in your diet once a week, but it’s best to alternate its consumption with that of other small fish, to avoid bioaccumulation.

However, what you should never do is eat raw tuna while pregnant, and much less, the red variety. The risk of intoxication caused by this species can be high and in some cases, the results are serious. Therefore, it’s worth stressing the importance of extreme food hygiene measures during pregnancy.
