It is in the human genome, specifically frugivorous nutrition for carbohydrates.
Such foods do not require culture, and are readily deconstructed by our biological apparatus, furthermore the kilo caloric restrictions of a higher non digestible carbohydrate ratio (ie fibre).
Grains lack fibre, and 'empty kilo caloric' carbohydrates may have NO fibre, this results significant biomass increase of our species, several hundred EXTRA kilo calories per human, daily.
This phenomnamay be a result of 'obesity', and even occurs to 'domesticated' organisms, that being cultural intervention.
I am surprised, farmerman, specifically this quote:
We shouldnt be afraid of our food, and if you need a reason to eat something, then you are missing the whole point of food enjoyment
Vegatables may not satisfy your
conditions of "flavouring", it is uncertain for now, however it is suggested that vegatables do release toxic substances when heated, hence the 'lack of taste', perhaps.
My personal experience suggests that vegatables, and most certainly fruit do have a better taste than meat or processed carbohydrates/fats, or are you suggesting that sodium and glucose manipulation of food industry sellers is "the point" of nutrition?
You are appealing to normatives, furthermore you continue to appeal to the 'creationist' nomenclature, where is your genetic basis for the human diet?
Worst of all, I must subject myself to a genetic fallacy to suggest this.
Let us exclude culture, contemporary environmental consequenses for a sustaining cultural basis is extrinsic

It has been suggested that starvation exhibits neuro adaptative phenomena.
You are stranded in the sea for 90 days, during this phase you may only have access to the seawater organisms.
Initially, the captured seawater organisms do appear to be "flavouring", perhaps the most that will be consumed is the outer tissue (minus the skin), however after three weeks symptoms of malnutrition are observable.
Neurology will eventually overide this 'irrational' behaviour, kilo caloric restrictions may not even be necessary, the eyes, skin and organs will appear "flavouring", or more specifically nutritious
in this case.
