It’s a question we hear a lot at John West? 

Is it safe to eat tuna? Can I eat tuna every day? Is mercury in tuna something to worry about?

Tuna is loaded with protein, contains essential vitamins and minerals, and is rich in omega-3 fatty acids, making it a nutritious, and delicious, food for your diet.The concerns around daily intake stem from its mercury content.

However, according to the NHS, which states a healthy, balanced diet should include at least two portions of fish a week, there’s nothing there to say you can’t eat tuna every day, unless you’re trying for a baby, or pregnant.

It is, though, always a good idea to balance it with other protein sources, and always consult dietary recommendations for specific health needs.

Tuna, thanks to its versatility, unmistakable taste, and immense nutritional benefits, has been a firm family favourite for decades.

So, if you’ve been eating the tinned variety every day, or most days, for as long as you can remember, you have no reason whatsoever to be worried. 

The same applies to tuna’s mercury content, although it’s always smart to stay informed when it comes to your health.

John West canned tuna is regularly tested for mercury and other potential environmental contaminants, and the detected levels are extremely low – well within the limits set by EU and UK regulations.

However, the UK Food Standards Agency does recommend that if you are pregnant, or trying for a baby, it’s best to limit your intake to no more than the equivalent of four cans per week.

You’ll almost always find the word ‘balanced’  paired with ‘diet’ whenever it’s mentioned. 

Because without balance, your diet could end up all proteins, no greens; or even worse – all ice creams, no proteins. 

Overconsumption or underconsumption of certain food groups can lead to a range of health issues, from weight gain to nutrient deficiencies.

Incorporating both tinned and fresh into your weekly meals is a great way to enjoy a variety of nutrients. 

While both are high in protein and  omega-3 fatty acids, tinned tuna’s convenience and long shelf life add to its appeal.

Look up ‘healthy food source’ in a dictionary and you’ll see a picture of tuna. 

Ok, tinned tuna isn’t the only healthy food source out there, but when you’re looking at taking your meals and fitness journey to the next level, it’s hard to beat. 

Brimming with protein (one can of tuna can contain up to 25g), rich in omega-3 fatty acids, containing a number of  essential vitamins and minerals, AND low in calories – tuna’s impressive nutrient profile supports muscle growth, heart and brain health, and overall well-being.

While tuna can be a nutritious addition to any diet, it’s important to limit your intake when pregnant or breastfeeding due to its mercury content.

The UK Food Standards Agency recommends that women who are pregnant or breastfeeding should eat no more than four cans of tinned tuna, or two portions of fresh tuna per week. This limits mercury exposure, but also means you are still able to benefit from the high-protein and omega-3 fatty acids content.

Whether or not you choose to eat tuna daily as part of a balanced diet comes down to one thing – personal preference. 

Unless you are trying for a baby, pregnant, or breastfeeding, there’s no reason why tinned tuna can’t become a daily mealtime go-to in your home. 

As with all diets, though, variety is key. John West has a wide range of flavours and product types sure to appeal to all tastes, but it’s also important you include different protein sources as well. Beef, eggs, beans, lentils, and nuts are all excellent options, and will ensure your body is benefiting from all the nutrients it needs.
