I reckon that raw fruits and veggies may contain a certain amount of SF and IF, but SF is a lot more accessible when something as cooked as opposed to when it's raw.
So I cook mushrooms, I steam dark green veggies (even rocket salad, I really like the taste still), never eat green salads raw, I cook strawberries, raspberries, blueberries and various red/black currants into my oats.
I prefer cooked or warm food anyhow taste and texture-wise, always have done. I even prefer toast to normal bread. But this is probably an idiosyncrasy of mine.
