What is psyllium?

Psyllium, or "qatouna" as it is called in Arabic, is the husk of the seeds of a plant called Plantago ovata. It is almost pure fibre: there are 85 g of fibre per 100 g!

How many calories are in psyllium?

There are 190 calories per 100 g, but a tablespoon (5 g) has about 10 calories and 4 g of fibre. So one spoon gives you more fibre than a whole apple.

Does psyllium raise blood sugar?

No. It has almost zero available carbohydrate, because it is mostly fibre that is not digested, so the glycemic index does not apply to it.

How does it work?

Psyllium absorbs water and becomes like a gel. This gel moves through the gut and adds bulk and softness. That is why many people use it for constipation, and also because it gives a feeling of fullness.

Watch out for these things

  • You must take it with plenty of water, at least a full glass, otherwise it can get stuck or cause a blockage.
  • Start with a small amount (half a spoon) and increase gradually, because it can cause bloating at first.
  • If you have any health condition, ask your doctor before you start taking it.

How to use it

  • A spoon in a glass of water or juice, and drink it quickly before it sets.
  • You can add it to oats or yoghurt.
  • In gluten-free baking, it is used to bind the dough.
