If you do eat berries, I would consider the mold content of eat of them. For instance, raspberries and strawberries are rather high in mold content while blueberries are relatively low. If you left a bunch of raspberries or strawberries in front of the windowsill during a warm sunny day…they would go bad within hours while blueberries would last a little bit better.
Also, I’ve had trouble with frozen fruits…they don’t seem to digest nearly as well as fresh fruits (just mentioning it).
Fruits benefits benefits were mentioned by javizy, but I’ll add another one; fruits heal leaky gut as well.
