A quote from Huel’s website says: “I was comfortable and can vouch for this practically, in addition to noting there are no FODMAPs on the ingredients list.”
OK, cool, I though, because I’m currently following the low fodmap diet and I’ve got 5 kg of Huel left
Well, from the beginning, this claim cannot be 100 percent true as it most probably is low fodmap, not NO fodmap, but that’s fine.
A quick look at the ingredients, however, made me wonder if this claim about being low fodmap is actually true.
The main ingredient of the classic shake is oats. According to Monash, oats are low fodmap when serving size is 60 grams. They are high in GOS when serving size is 100 grams. I’m assuming they are moderate in GOS for serving sizes in between those two values. (btw not only GOS but also fructans, but let’s focus on GOS).
I’m assuming there is around 50 grams of oats per 100g grams of huel.
Another ingredients is flax seeds. Monash says its moderate GOS for servings larger than 15 grams. It’s high in GOS when 30 grams are consumed.
Based on the omega 3 content in huel it most probably is between 11 and 16 grams.
So for a serving of a 100 grams we already have 2 ingredients that individually are probably low fodmap, specifically GOS, but together almost certainly are at least moderate fodmap. The reason I’m assuming this is because both of the ingredients are at their upper limits when it comes to being low in HOS
The phenomenon is called, AFAIR, fodmaps stacking and is also described by Monash, so I haven’t come up with it myself.
I might be wrong in my calculations so I would be very grateful if you could explain this to me.
Kind regards
