ESTRALAInsulin is a hormone that, after a meal, "opens the door" of cells to glucose — it allows the fuel to enter. When everything works smoothly, blood sugar levels rise moderately after eating and quickly return to normal. The problem begins when cells stop responding to insulin the way they should. This is precisely insulin resistance.
What happens step by step
The mechanism can be described fairly simply. When a diet is rich in simple sugars and highly processed carbohydrates for years, the pancreas must keep releasing large amounts of insulin. Over time, cells become less sensitive to it — so even more insulin is needed to achieve the same effect. A vicious circle forms: high sugar → a lot of insulin → growing resistance → even higher sugar.
The silent phase that lasts for years
Insulin resistance can develop over many years before raised fasting blood sugar appears in tests. That is why it is sometimes called a "silent" disorder — and why it is worth responding to the signs early, rather than only at the point of a diabetes diagnosis.
Let's not demonise "sugar" in general
It is worth keeping a sense of proportion. Glucose is the body's basic fuel, and carbohydrates are not in themselves the enemy. The key factors are quantity, quality and context: wholegrain products with fibre are absorbed more slowly than a sugary drink, and the same dessert eaten after a hearty meal will raise blood sugar differently than on an empty stomach. The problem with the modern diet is not so much "sugar as such", but its excess in a rapidly absorbed and ubiquitous form.
The most important change usually lies not in a single ban, but in shifting the whole diet: fewer simple sugars and processed products, more fibre, protein and healthy fats.
What really improves insulin sensitivity
- Movement — especially after a meal. Working muscles use up glucose independently of insulin. Even a short walk after eating makes a difference.
- Fibre and whole foods. They slow the absorption of sugars and soften glucose spikes.
- Limiting simple sugars and sweetened drinks. This is usually the biggest lever.
- Sleep and the reduction of chronic stress. Lack of sleep and high cortisol worsen sugar metabolism.
- Losing excess body fat, particularly visceral fat, usually clearly improves insulin sensitivity.
Where do fats and Omega‑3 fit in
Sugar metabolism and fat metabolism are linked — a diet with a favourable fat profile is part of the same puzzle. Replacing some saturated and processed fats with unsaturated ones, including Omega‑3, fits into a way of eating associated with better metabolic health. Plant-based alpha‑linolenic acid (ALA) is a convenient way to consciously add such fats to the diet — especially when we rarely reach for fish.
It must be said honestly: ALA is not a "cure for insulin resistance" and should not be treated as one. It is, however, an element of a diet that as a whole promotes health. The only officially confirmed EU health claim for ALA concerns the maintenance of normal blood cholesterol levels (with an intake of 2 g per day).
The key points at a glance
- Insulin resistance is a decline in cells' sensitivity to insulin — it develops over years, silently.
- The problem is an excess of rapidly absorbed sugars, not carbohydrates as such.
- Movement (especially after a meal), fibre, sleep and weight reduction really help.
- A favourable fat profile, including Omega‑3 (ALA), is part of a healthy diet — not a medicine.
