I was curious so I searched for extra context: from the same document, the mean diet-related intake quantities for aluminum in norway are 0.29 mg/kg bodyweight/week; this means that if you are 70 Kg, you would normally ingest about 20mg of aluminum a week.

Assuming you drink a whole liter of "aluminum moka coffe" a week, you get 0.81mg extra aluminum in your diet. A liter is about 16 "italian cups". You would get a heart attack before noticing symptomps of aluminum intoxications...
