Sugar alcohols in Grenade bars:
Carb Killa Salted caramel - 15 grams
Peanut nutter - 13
Peanut butter and jelly - 17
Birthday Cake - 15
Chocolate Crunch - 12
Dark chocolate mint 13
These grenade bars have really high amounts of sugar alcohols.
I would bet Huel is using similar values especially being people are saying these bars are very sweet tasting.
