Scientists Discover Previously Unknown Cleansing System in Brain
The highly organized system acts like a series of pipes that piggyback on the brain’s blood vessels, sort of a shadow plumbing system that seems to serve much the same function in the brain as the lymph system does in the rest of the body – to drain away waste products.
“If the glymphatic system fails to cleanse the brain as it is meant to, either as a consequence of normal aging, or in response to brain injury, waste may begin to accumulate in the brain. This may be what is happening with amyloid deposits in Alzheimer’s disease,” said Iliff. “Perhaps increasing the activity of the glymphatic system might help prevent amyloid deposition from building up or could offer a new way to clean out buildups of the material in established Alzheimer’s disease,” he added.
This is just another example of things being a bit more complicated than just what we put in our bodies but also of how our bodies deal with those things. Now, I will say that if a person has this system working sub par then the OP's advise to stay away from the foil may be in order.
Seeing that aluminum is in many foods, the problem then becomes trickier. Finding what contains aluminum and in what amounts seems rather difficult. All I could find was an FDA statement stating that most foods contain it. Who knows, maybe a push for its inclusion in food labels is in order.
