Flax and chia seeds: two or three spoonfuls a day
Two to three spoonfuls a day. Flax and chia provide the fiber that is usually lacking on a low-carb diet: grains and fruit are gone, and there is almost nothing else to replace them with. You must not eat them without enough water.
Why fiber at all?
Because when you change your diet, the first thing to change is your bowel movements, and that is the most common complaint of the first month.
Vegetables provide some fiber, but the volume of salad is limited by how much a person can actually eat. Flax and chia add it in concentrated form: two spoonfuls take up little space on the plate but have a noticeable effect.
The second effect is satiety. Chia swells in liquid and maintains volume in the stomach, which helps you not think about food between meals.
How does flax differ from chia?
| Flax | Chia |
|---|---|
| Type of fiber | more insoluble |
| Omega-3 | eat |
| how to eat | grind before eating |
| Where does it go | in salad, with cottage cheese, in minced meat |
| Storage | whole seeds, grind as needed |
Why should flaxseed be ground?
Because the whole seed passes through the gastrointestinal tract without opening up, providing almost no benefit.
It is best to grind it immediately before eating: ground flaxseed oxidizes and turns bitter quickly. A coffee grinder does the job in ten seconds, so there is no need to make a week’s supply.
If you have nothing to grind it with, chia is simpler in this respect: it works whole and only needs liquid.
How should I introduce them?
Start with one spoonful and increase to two or three over several days.
Three spoonfuls at once can cause bloating in an unaccustomed gastrointestinal tract — the same scenario as with sauerkraut and fats. Halving the amount and increasing it more slowly solves the issue in most cases.
The time of day doesn’t matter. The most convenient option is with your first meal, added to cottage cheese or a salad.
What do people most often do wrong?
- Eat whole flaxseed and wait for an effect
- Start immediately with three spoonfuls
- Forget about water
- Grind flaxseed in advance for a month
- Consider chia pudding with honey a low-carb dish
When this is not suitable
With inflammatory bowel diseases, diverticulitis during a flare-up, and after gastrointestinal surgery, the amount of fiber should be discussed with a doctor.
When taking medication, it should be separated from the seeds by some time: fiber can slow absorption. If you are prone to constipation, it is better not to add seeds without sufficient fluid intake — first, establish adequate hydration.
Where should they be added?
Flax is most convenient in hot dishes and minced meat: grind it, stir it in, and you won’t notice it. Another option is to sprinkle it over a salad right before eating.
Chia, on the other hand, works best in something cold and liquid. Pour two or three spoonfuls of water, coconut milk, or cream over a spoonful of chia and let it stand for fifteen minutes — you’ll get a thick mixture that can be eaten with cottage cheese or on its own.
A simple, practical option for every day: a spoonful of chia in cottage cheese in the morning and a spoonful of ground flax in a salad during the day. Your daily amount is covered, with no fuss.
How should you store them?
Whole seeds — in a sealed jar in a dark place; they keep for months.
Ground flaxseed is a different story: it oxidizes within a few days and starts to taste bitter. There’s no need to grind it in advance; a coffee grinder does the job in ten seconds. If you do grind too much — store it in a jar in the refrigerator and use it within a week.
A rancid taste doesn’t mean “that’s how it should be”; it’s a sign to throw it out.
Do they replace fish?
No. Omega-3 in flax and chia is a plant-based form, and the body converts it into the form it needs poorly and in small amounts.
Therefore, fatty fish several times a week remains part of the plan, while seeds stand alongside it, not instead of it. Their main job here is fiber, and they handle it better than any other food in the diet.
You also shouldn’t replace fish with capsules without a doctor’s prescription.
