Fish in the Diet – Health on a Plate or a Marketing Hook?

Fish in our diet is a topic that comes back like a boomerang.
Sometimes we praise them to the skies, other times we warn about toxins and antibiotics.

But what’s the truth?
Is fish always healthy?
And why has smoked mackerel become my culinary weakness?

🧠 Why Should You Include Fish in Your Daily Diet?

Fish are not only tasty but also incredibly nutritious.
Their greatest asset? Omega-3 unsaturated fatty acids, especially DHA and EPA, which:

• support the nervous system,
• improve memory and concentration,
• reduce the risk of heart disease,
• decrease inflammation,
• benefit skin and eye health.

That’s why the World Health Organization (WHO) recommends eating fish at least twice a week.

According to a study published in The American Journal of Clinical Nutrition, people who ate fatty fish at least twice a week had a 17% lower risk of heart attack.

🍽️ A Personal Note: Smoked Mackerel – Queen of My Table

To me, fish tastes like… smoked mackerel.
Its intense aroma, fatty texture, and bold flavor remind me of childhood, family weekends, and dinners that didn’t need fancy recipes.

What’s more, mackerel is genuinely healthy:

• it’s rich in omega-3,
• it’s a good source of protein,
• it provides B vitamins and vitamin D,
• it’s easy to prepare – just a slice of bread and a bit of lemon.

But beware! It’s also high in salt.
Smoked products – delicious as they are – should be eaten in moderation.

🧪 Fish Farming – An Industry That Raises Questions

Many of us buy fish with good intentions.
But few realize that a large portion of fish sold in stores comes from industrial fish farms.

Sounds harmless, but the reality can be alarming:

• fish are often kept in overcrowded tanks,
• fed artificial feed,
• may receive antibiotics to prevent disease,
• and their environments pollute local ecosystems (source: The Humane League).

Studies show that farmed fish may contain less omega-3 than wild ones.
Worse yet, some farms (especially in Asia) have been accused of using illegal preservatives and dyes to make fish look “fresh” for longer.

☠️ Mercury and Other Heavy Metals

Large fish like tuna, swordfish, and shark may contain high levels of mercury, which harms the nervous system.
Children and pregnant women should limit or avoid them.

🧭 How to Eat Fish Wisely?

Here are a few simple rules:

• Choose wild fish with the MSC (Marine Stewardship Council) certificate.
• Limit large predatory fish – opt for sardines, herring, mackerel, or trout instead.
• Read labels – especially country of origin and farming method.
• Rotate your fish choices – don’t always eat the same kind.

🔚 Summary – Fish in the Diet: Yes, But Wisely

Fish in the diet is a complex issue.
On one hand, they offer tremendous health benefits.
On the other – some sources are far from ideal.

Is it worth eating fish? Yes!
But not all, not always, and not blindly.

And mackerel? I still love it – I just know which one to buy and when to say “enough”.
