It's true that if you eat fat, protein and fibre alongside sugars, the effective GI of the sugars is reduced. But I really don't think see how that makes measurements of individual foods misleading. How is it any different than individual foods being labelled with calorie counts and macro-nutrient figures? Edit: I think the article uses the high GI of a sugar ingredient to claim that Oatly is bad - yes, this is misleading; the GI of the whole product is what matters.
