Fruit is perfect "IF" you eat it correct. "IF" you eat/drink fruit with bad food in your stomach, then yes, it will ferment and push the mud down the tube!
FRUITS are to be eaten raw, one type per meal, never mixed with anything other than water as needed.
fruits cleanses your blood and corrects the digestion and restores health.
The rotten accumulated foods will ferment and loosen and come out and once out your syptoms will be gone.
NEVER BLAME RAW FRUIT, it is not God's Fault, the fruits are made correct.
