Humanity has eaten grains as a staple part of our diet for millenia. Sugars are present in solid non-sweet foods in relatively small amounts and are mych slower digested than sugared fluids and I don't get the chorus of "seed oil bad" that's become a fad in the past five years.
Discussion
Our ancestors lost a foot of height and 10% brain mass when they started eating grain.
You implicitly admit the amount of sugar is what matters, and ignore the fact that modern processed food (including bread) has an order of magnitude more refined sugar than the foods of our grandparents.
If the "long" history of human grain consumption (a blink of an eye compared to our millions of years eating meat) shows the relative safety of grain, why does the short history of seed oil consumption (less than 200 years) not indicate a lack of such safety?
I'm not buying it. You have no way of knowing the body mass of our pre-agricultutal predecessors since most BM is soft tissue that's gone for good and using skeleton size as a proxy is far more indicative of general malnutrition, especially malnutrition during the growth phase of our youth, as we also know from comparing North Koreans (chronic malnutrition in the general pop) to South Koreans.
Humanity has only known widespread, relative food safety for the last ~100 years of our civilization, before then we had to be opportunistic to have a shit at survival*, or even in our hunter-gatherer stone age past, superopportunistic like all animals, since there were zero guarantees that the prey animals would be in the area next year or even next week for that matter.
Agriculture at least gave humanity options in our diet that didn't involve eating bark or hoping for a brief starvation.
As for sugars (as opposed to carbohydrates in general), I've been warning people about the dangers of excessive simple sugar intakes for over a decade, so I don't see how we're at odds here unless you don't like carbs at all. If you want to get rid of most of your body adipose tissue in a rush, cutting carbs will do the trick, but weight crashing will possibly also have negative CV effects. But you do you I suppose.
Likewise irt. oil intake. The same warning that goes for simple sugars goes for dietary oils (sdded FA) intake; everything in moderation is a golden rule for a reason, though my understanding is that fats (barring trans-fats from poor-quality oils that are heated to excessive temperature, in essence: deep frying and 'bad' fast food, and omega-6 FAs) are generally good, and saturated fats have an endeserved bad reputation due to bad dietary research in the 70s & 80s that gave rise to the current sugar paradigm. The fats in and around meat is pretty good as far as I'm concerned.
