Senile Dementia Diet

Whether aluminum in the diet can cause Alzheimer’s disease remains controversial. A preliminary study found Alzheimer’s disease patients are more likely to have consumed foods high in aluminum additives (e.g., some grain product desserts, American cheese, chocolate pudding, chocolate beverages, salt, and some chewing gum), compared to people without the disease. Until this issue is resolved, it seems prudent for healthy people to take steps to minimize exposure to this unnecessary and potentially toxic metal by reducing intake of foods cooked in aluminum pots, foods that come into direct contact with aluminum foil, beverages stored in aluminum cans, and foods containing aluminum additives. Aluminum is added to some municipal water supplies to prevent the accumulation of particulates. In such areas, bottled water may be preferable. It appears unlikely, however, that avoidance of aluminum exposure after the diagnosis of Alzheimer’s disease could significantly affect the course of the disease.

In population studies, high dietary intake of fat and calories was associated with an increased risk for Alzheimer’s disease, whereas high intake of fish was associated with a decreased risk. Whether these associations represent cause and effect is unknown.
