Nutrition is a field, from the science perspective, that does not work in absolutes. It is too complex of a field for us to really pin anything down for populations or individuals. That is why we as individuals have to find a way to tune it, ideally with expert input. That is why I take issue with statements like "objectively worse," which is really the only reason I commented in the first place. But I would like to see where you are getting 30g because everything I have seen (we'll include [1] link but my quick googling brought up comparable results) puts sugars, combined complex and simple, at ~40% to 65% of your daily diet. It is often quoted at about ~200g to 300g. Yes, people over-do their sugars, yes people think that eating all the fruit is healthy when in fact it is still a bunch of sugar, but in the end a body with moderate activity needs carbs to break down for quick energy. It would be inefficient for our bodies to go into fat stores or slow-burn protein every time we need energy.
