Tuna vs Catfish – Which is Healthier?

Our Verdict

When comparing tuna to catfish, we picked the tuna.

Why?

Today in “that which is more expensive and/or harder to get is not necessarily healthier”…

Looking at their macros, tuna has more protein and less fat (and overall, less saturated fat, and also less cholesterol).

In the category of vitamins, both are good but tuna distinguishes itself: tuna has more of vitamins A, B1, B2, B3, B6, and D, while catfish has more of vitamins B5, B9, B12, E, and K. They are both approximately equal in choline, and as an extra note in tuna’s favor (already winning 6:5), tuna is a very good source of vitamin D, while catfish barely contains any. All in all: a moderate, but convincing, win for tuna.

When it comes to minerals, things are clearer still: tuna has more copper, iron, magnesium, phosphorus, potassium, and selenium, while catfish has more calcium, manganese, and zinc. Oh, and catfish is also higher in one other mineral: sodium, which most people in industrialized countries need less of, on average. So, a 6:3 win for tuna, before we even take into account the sodium content (which makes the win for tuna even stronger).

In short: tuna wins the day in every category!
