I think so, if you had a choice of the food you ate with an eye to digestibility and care with your teeth.
Unripe apple juice works to marinate/soften foods too, so you wouldn't need to import limes.
If you crack and soak grains, they'll ferment and soften too. Peas if soaked will sprout. Fish often doesn't need to be cooked to be edible, and meat can be pounded to break down the fibres…..loss of energy to gain protein there though.
Salads are a classic no cook too
Not everything works to give full benefit however. We're very fortunate and have no famine situation and loads of choice.
