Not in the real world, but those fairytales are effective for newbies. I think apples are only good to slowly detox the gut from aluminum as the pectin will not bind to any aluminum but the intestinal one. Metal detoxification isnt easy, and certainty no one will detox aluminum with only eating apples.
I used to eat everyday lots of apples and even ended taking Mag Malate almost Cutler style with Silica. The results were two scary attacks of mental problems. In my opinion, malic acid only moves the aluminum around brain and nervous system and furthermore it has the theoric ability to drain more aluminum INTO the brain. Plus it also enhances absorption the same as excretion. Not the best deal.
Not saying eating apples can trigger those symptoms, I was taking concentrated AOR mag malate four times per day with liquid silica. That was what opened the Gates of Madness.
But thanks for reminding me! I think if I have to eat some fruit apples will be in the list.
