Psyllium husk is the least glamorous ingredient in the bar and the one with the strongest official standing behind it.
Soluble fibre from psyllium husk is the subject of an FDA-authorised health claim relating it to reduced risk of coronary heart disease. Authorised health claims are a high bar — the FDA reviews the evidence and specifies the exact wording and the qualifying amounts. Very few food ingredients clear it.
It also does structural work in the recipe, and it comes with one instruction that matters more than anything else on this page.
What it does in the bar
Psyllium is a soluble fibre that forms a gel when hydrated. Two consequences.
Texture. That gelling helps bind the bar and keeps it from crumbling, which is why we can avoid gums and added starches.
Fullness. Soluble fibre slows gastric emptying, which is a large part of why a bar of this size satisfies for longer than its calorie count suggests.
Drink water with it — this one actually matters
Psyllium absorbs many times its weight in liquid. Taken in concentrated form without enough fluid it can cause choking or obstruction, which is why psyllium supplements carry explicit fluid instructions.
The amount in a food bar is far smaller than a supplement dose and is already mixed into a moist matrix, so this is not an alarm. But if you are eating a high-fibre bar, having water with it is sensible — and if you are increasing fibre generally, increase it gradually.
Psyllium Husk: common questions
Is psyllium husk good for you?
Psyllium is a soluble fibre, and soluble fibre from psyllium husk carries an FDA-authorised health claim relating it to reduced coronary heart disease risk as part of a diet low in saturated fat and cholesterol. It is also widely used for stool regularity.
Why is psyllium husk in a protein bar?
Two reasons: it binds the bar without gums or added starch, and as a soluble fibre it contributes to fullness by slowing gastric emptying.
Will psyllium husk upset my stomach?
Fibre added suddenly and in quantity can cause gas or bloating. The amount in one bar is modest and already hydrated within the food matrix. If you are sensitive, introduce high-fibre foods gradually and drink water alongside.
