surely must be just some weird phenom. If its sugars etc. Do you do the same with sodas or other juices? I mean those would be high in sugar.
Switch to orange juice, pineapple juice see if you get the same. If we are that sensitive to the pesticides and waters used in crop productions not sure what we can eat?????and drink!
California is the worlds lead on all these lead warnings and although there is concern there the warnings are very hypersensitive vs other states.
In engineering even power cords on appliances such as your hair dryer, vacuum cleaner, etc have to have lead warnings and heavy metal testing conducted on all plastics and materials used in the construction.
We surely can not eliminate water treated products (produce, veggies); appliances made of plastic; textiles; PolyVC's in goods. This is one time they need a cure for the symptoms and not the cause if thats the case!!!
