i agree wholeheartedly with the spirit of your comment, but saying "nutritional science is complex" or "the dosage alone makes it so that a thing is not a poison" does not help people figure out what foods to choose or how much to consume.
looking at the glycemic index is a useful heuristic and some of the research on canola oil makes me skeptical of it, and i think it is good for the author to point that out, as it suggests that oat milk might not be as safe as it is marketed to be.
another heuristic is biasing in favor of food that is processed less eg eating a bowl of oats is probably a better idea than drinking the analogous amount of oatly. similarly, it is a good idea to eat foods that people like you have been eating for long times, which in the oats vs oatly example favors the oats.
the precautionary principle suggests that the onus is to verify the safety of a given new food, not to prove that it is unsafe.
