You’ve built a strong foundation — steady glucose, fibre first, and balance through the day. This step adds the quiet nutrient that keeps the engine smooth: omega-3 fats. If you already eat oily fish twice a week, brilliant — you can tick this step off right now. You’re already giving your brain and heart what most people miss. Statistics show that the majority of adults don’t. For many, it’s a mix of habit, cost, and taste.

Fish doesn’t trigger the same pleasure signals as a juicy steak or a crispy roast chicken, and a piece of salmon can feel like a risky buy if you’re not sure you’ll enjoy it. This step exists because I was one of those people. It’s a gentle invitation to experiment — to see whether your tastes, budget, and health priorities might line up differently now than they once did.

Why it matters

Omega-3s form part of every cell membrane in your body. They keep the brain’s wiring flexible, support the heart, and help your immune system switch inflammation off once it’s done its job. Modern diets often lack them because the best sources are foods we don’t eat very often.

Best source — oily fish Salmon, sardines, herring, and mackerel provide the ready-made forms EPA and DHA that your body can use directly. Even one portion a week makes a measurable difference; two is ideal. Tinned or frozen versions are fine — convenience counts more than glamour.

Everyday support — plant omega-3s Flaxseed, chia, hemp, and walnuts contain ALA, a shorter version that your body can partly convert. Add them daily: a spoonful of ground flax or chia in yoghurt, or a few walnuts with fruit. They don’t replace fish entirely, but they keep your overall balance better.

Last resort — supplements

If you rarely eat fish and can’t face starting, an algae-based omega-3 capsule can fill the gap. Look for one that lists both EPA and DHA on the label. It’s not a magic bullet — just a safety net.

Why this works

Balancing your fats changes how every cell behaves. When omega-3s replace some of the processed oils in modern diets, inflammation eases, insulin works more smoothly, and brain function stays sharper. You don’t need perfection — just a little more of the right kind of fat, often enough to matter. Step 13 is about maintenance and repair — the quiet chemistry that keeps all your earlier steps running smoothly. Start where you are, add what you can, and let consistency do the rest.

What if I Don’t Eat Fish?

You’re not broken — you almost certainly have some omega-3 in your system already. “Essential” just means your body can’t make it from nothing. Most people get small amounts of ALA, the plant version of omega-3, from foods like oats, greens, rapeseed (canola) oil, walnuts, chia, and flaxseed.

Your body can convert a little of that into the long-chain forms (EPA and DHA) that fish provide. It’s not terribly efficient — roughly 5 % to EPA and 1–3 % to DHA — but enough to keep the basics running. So you’re not likely to be deficient, just running a low-supply model.

That’s why adding a few richer sources — fish if you like it, or regular seeds and nuts if you don’t — can make a noticeable difference over time.

If you truly avoid all fish, an algae-based omega-3 capsule is a practical fallback, not a failure. The goal isn’t to become a fish eater; it’s to nudge the fat balance in your favour. Your brain, joints, and recovery systems will quietly thank you for it.

Getting Started with Fish

If you’re new to fish, start gently — but keep the goal in mind: omega-3 fats. Not all fish deliver them equally. The real omega sources

• Salmon – the easiest place to start. Mild, meaty, and forgiving to cook. Try it oven-baked with lemon or enjoy cold-smoked salmon with eggs or salad — rich in omega-3 but light in flavour.

• Trout – similar to salmon, slightly sweeter, quick to cook, and high in omega-3.

• Sardines, mackerel, and herring – the strongest natural sources. They taste bolder but reward you with the biggest omega boost. Try them grilled, stirred through tomato sauce, or turned into pâté with lemon and yoghurt.

• White fish (cod, haddock, pollock, hoki) are excellent lean proteins — low in fat and saturated fat — but contain very little omega-3. Think of them as your light protein choice, not your omega source.

• Tuna is a halfway house. Fresh tuna steaks have some omega-3, but much less than salmon. Tinned tuna, though convenient, loses most of it during processing — still a healthy protein, just not for omega-3s.

I don’t like fish

Many adults still carry the childhood memory of hating oily fish. Taste, though, changes with age — the same way dry wine or strong coffee often grow on us. It might be the memory of dislike that’s stronger than the taste itself. So take a small budget, go buy a piece of salmon or trout, and simply try it again. If you still dislike it — fine, you’ve confirmed it honestly. But there’s a good chance it won’t be nearly as bad as you remember. And remember: how it’s prepared matters.

Raw salmon in sushi tastes clean and buttery; cold-smoked salmon is silky and savoury; a hot-smoked fillet is flaky and rich. Different textures, different experiences — one of them may surprise you. Keep it simple A portion is about 100–140 g cooked weight — roughly a palm-sized fillet.

Frozen or tinned oily fish is fine; omega-3 survives both.

Pair fish with lemon, tomato, or vinegar to keep flavours bright.

Cook once, eat twice: leftover salmon or trout flakes beautifully into salads, omelettes, or pasta.

Your goal

Aim for one oily portion a week to start.

That’s already a meaningful step toward a better omega balance. Once it becomes routine, add a second — but even one consistent portion of salmon or trout is enough to move the needle.

The aim isn’t to become a seafood lover overnight. It’s to find one or two mild, easy types you genuinely enjoy — because enjoyment means repetition, and repetition builds the habit that keeps your omega levels steady.
