Aluminium is the most abundant metal in the Earth's crust, and makes up about 8% by weight of the Earth’s solid surface. Because aluminium is too reactive chemically to occur in nature as the free metal it is combined in over 270 different minerals.

Due to the implication of aluminum's role in Alzheimer's disease, Meal Genius recommends you avoid aluminum.

Primary dietary sources of aluminum include medications (antacids), tap water, baking powder and cake mixes (sodium aluminum phosphate, anti-caking agents). You may also be getting aluminum from aluminum cans and cookware. Be advised that acidic or highly salty foods tend to leach more aluminum out than other foods.
