Wholly disagree. Most people would not touch raw potatoes, given the appalling taste thereof.
That’s true:
most people, as you rightly write. But “most people” isn’t synonymous with “everyone”! The taste of something is dependant on 2 factors: the thing itself and the animal (individual) who is tasting it. Something may be tasty for someone at a given moment and appalling for somebody else at the same moment.
My question is then this: Is it important to put on a plate any type of food that could've harmed us in their processed form in the past, to see if our body is attracted to them for healing purposes?
eg: Put plain wheat grass or sprouts on the table and see if our senses make us want to nibble on it, or eat it whole.
Or put sugar beets and sugar canes to see if our body wants to detoxify from the processed sugar.
Not wheat: raw or not, it’s a troublesome food, like dairy. Drinking raw milk or eating raw wheat won’t help our body to detoxify from cooked wheat or cooked milk: on the opposite, it will add new toxins without giving any instinctive sign to stop.
But sugar cane, as every unprocessed paleo foodstuff, can be useful and should not be excluded a priori. Raw potatoes, as an extreme example, show a very strong and clear instinctive stop so that there’s no risk to eat too much of it.
Most people will never feel like eating the slightest amount of it and will even spit it if they try.
However it’s true that at the beginning we often tend to eat huge amounts of some specific raw paleo foodstuff, for example 35 eggs yolks or a whole big bonito fish in a single meal, a kg of boar everyday during a few weeks, several melons or durians everyday during a period, etc.
