Top 5 Health Benefits Of Canned Tuna

1. Source of high-quality protein

Fish is a source of a high-quality protein, and canned tuna in particular offers an affordable protein source and makes a useful storecupboard staple.

2. Useful source of the amino acid taurine

As well as being a source of protein, seafood, including fish like tuna, is a useful source of the amino acid taurine. Studies suggest this amino acid may be helpful for protecting against heart disease.

3. Useful source of vitamins and minerals

Both fresh and canned tuna are a useful source of B vitamins, especially niacin (B3), which supports the nervous system and skin. Tuna also contains calcium, which supports healthy bones and muscle contractions; magnesium, required for energy; and vitamin D, which supports the immune system, bone strength and brain function. Fresh tuna (per 100g) has double the amount of vitamin D compared to that of canned tuna.

4. Low in fat

Tuna is low in fat, with just 1g of fat in a 100g edible portion – this is also the case for tuna canned in spring water or brine.

Although once considered an oily variety of fish, the type considered beneficial for heart health, the UK’s official advice on oily fish changed in 2018, with tuna no longer counting as a good source. This is because current data shows that levels of the long-chain omega-3 polyunsaturated fatty acids in fresh tuna are more comparable to that found in white fish.

5. May help weight management

Tuna, including canned tuna in spring water or brine, is low in fat and calories, but high in protein, making it a useful inclusion in a weight loss diet.
