The waiting room smelled faintly of disinfectant and old magazines. On the wall, a faded poster about cholesterol tried to look cheerful. Across from me, a woman in a navy blazer was scrolling through recipes on her phone, pausing every time she saw grilled salmon or avocado toast. The door opened, and the doctor called her in. Ten minutes later, she came out, eyebrows raised, whispering to her partner: “He told me to eat more canned fish… but not sardines or mackerel.”
That stuck with me.
A few days later, I was in front of the supermarket shelf, staring at the rows of tins. Tuna, sardines, mackerel, salmon. Then my eyes landed on a smaller, almost shy label. And suddenly, the doctor’s voice made sense.
De arts die zweren bij… haring in blik
The doctor I met that day, a Dutch cardiologist in his fifties, has a very simple rule for his patients: “If it swims fat and small, eat it.” He’s crystal clear. For him, **haring uit blik** is one of the most underrated foods in the supermarket.
He sees people spending a fortune on supplements, omega‑3 capsules lined up like soldiers on the kitchen counter. Then they confess they barely touch real fish. So he goes back to basics. A cheap tin, a pull-tab lid, and a fork.
One of his patients, a 42‑year‑old office worker, came in exhausted, slightly overweight, with blood test results that screamed “pre‑everything”: prediabetes, pre-hypertension, pre-burnout. She ate on the go, lots of sandwiches, hardly any fresh products.
The doctor didn’t give her a lecture about kale smoothies. He asked her one thing: “Can you eat canned herring two or three times a week?” She shrugged. “I guess so. If it’s not disgusting.” They looked up a simple recipe together on his computer: rye bread, canned herring, sliced onion, a squeeze of lemon. Three months later, her triglycerides were down, inflammation markers calmer, and she said she felt “lighter in the head”.
Why herring and not the usual sardine or mackerel? Because herring is a cold‑water fish that stores a lot of omega‑3 in its fat, while staying low on the food chain. That means fewer contaminants than big predators, and a powerful dose of EPA and DHA in just a few bites.
Herring is also naturally rich in vitamin D and B12, nutrients many Europeans lack, especially if they work inside all day. And when it’s canned, those nutrients are basically locked in. *The tin quietly does the job while we rush through our lives.* For a doctor who knows most of his patients won’t cook fish twice a week, that’s pure gold.
Hoe je dat blikje haring écht slim gebruikt
The doctor’s trick isn’t just “eat more herring”. It’s “make it so easy you’ll actually do it.” He suggests choosing canned herring in water, brine, or a light oil, then turning it into a quick ritual.

One idea he loves: a “10‑minute Nordic plate” for dinner. Dark bread or wholegrain crackers, a tin of herring, a handful of cherry tomatoes, some sliced cucumber, mustard or yogurt with herbs. No cooking, just assembly. You open, you drain, you plate. That’s it.
Do it once or twice, you hesitate. Do it ten times, it becomes your lazy evening backup.
People feel guilty when they hear a doctor say, “You should eat fish twice a week.” We’ve all been there, that moment when you nod in the office, then order pizza at night. The cardiologist knows that. That’s why he repeats the same thing: “Don’t aim for perfection, aim for repetition.”
He warns about one common trap: flavored herring in heavy sauces, sugary marinades, or mystery “creams.” Those can turn a healthy tin into a salty, sweet bomb. So he asks his patients to flip the tin and read: fish first, then water, brine, or plain oil. Short list, simple words. Let’s be honest: nobody really does this every single day. But if you do it half the time, you’re already winning.
Sometimes, in his consultation room, he pulls a tin from his drawer, like a magician revealing a card. Patients laugh, but they remember.
“People expect a magic pill,” he says. “Often, the closest thing I have is a cheap tin of herring. Omega‑3, vitamin D, protein, almost no cooking. The body doesn’t care if it came from a fancy restaurant or a basic supermarket shelf.”
Then he gives a few concrete ideas and tells them to pick one:
- Mix canned herring with plain yogurt, lemon, and dill as a spread for toast.
- Add it to a warm potato salad with onion and gherkins for a quick dinner.
- Use it as a topping on a green salad with beans and radish for a hearty lunch.
- Blend a small amount into a vegetable dip if you’re not used to the strong taste.
- Keep one tin in your office drawer for days when you “have no time to eat well”.
Meer dan een blikje: een kleine dagelijkse keuze
What’s striking about this whole story isn’t just the fish. It’s the shift in mindset. Instead of chasing the perfect diet, the perfect recipe, or the perfect body, the doctor invites his patients to look at one small, repeatable gesture. A modest tin that could quietly change the numbers on their blood tests.
From the outside, it’s nothing. A metal box on a supermarket shelf. Inside, it’s a tiny answer to inflammation, low vitamin D, chronic fatigue. Not a miracle, not a cure‑all, but a nudge in the right direction.
You may not like the smell at first. You may prefer salmon or tuna. Or you may have childhood memories of herring that make you roll your eyes. That’s fine. The point isn’t to worship this fish. The point is to notice that sometimes, the smartest upgrade to your health hides in the least glamorous packaging.
Next time you’re standing in front of that brightly lit wall of tins, you might remember the cardiologist with his desk drawer full of herring. And you might, just once, reach for that unassuming can that is neither sardine nor mackerel, and see what happens in your own kitchen, and in your own body.

FAQ:
- Is canned herring really healthier than tuna?Tuna is often higher in mercury because it’s a bigger predator fish. Herring is smaller, fattier, and usually has more omega‑3 per portion with less contamination.
- What about the salt in canned herring?Some brands are quite salty. Look for versions in water or lightly salted brine and balance your day by avoiding other very salty foods when you eat it.
- Does herring in tomato or mustard sauce still have benefits?Yes, the fish is still rich in omega‑3 and vitamins, but some sauces add sugar, salt, or unnecessary fats. Checking the label helps you pick the best option.
- Can I eat canned herring if I don’t like strong fish tastes?Start with milder preparations: mix it with yogurt, herbs, and lemon, or combine it with warm potatoes. These soften the flavor and smell.
- How often can I safely eat canned herring?For most people, 2–3 times per week is not only safe but beneficial, especially if it replaces processed meats or fast food. If you have specific medical issues, ask your doctor.
