I don't care what the ongoing studies say, there is clearly a link between aluminum and neurological disorder in humans. It has long been well known that workers who breath aluminum dust or breath aluminum fumes perform lower than average on some tests that measure functions of the nervous system.
Some areas have higher aluminum content in the soil than others.
Aluminum is a non essential nutrient.

We probably shouldn't be ingesting aluminum ingots, but there doesn't appear to be any feasible way of avoiding constant incidental contact.
There are ways to avoid it, like you said on average al. content in soil is 7%, some soils much higher some lower. If you limit your exposure to foods grown in these high Al. content soils you could reduce your intake.
The soil ph has a lot to do with it as well as the ph of the fruit/veggy. Pineapple for example has much higher aluminum concentrations than other fruits due to the soil its grown in (acidic low ph, high al. tropical soil) and the acidity of the fruit itself.
