Of course, I'll change immediately. Because a website like FAITH PANDA is a trusted source of cutting edge medical research and did NOT try to hack my computer while I went to view your link..
STUPIDITY maybe if you stop using the foil and teflon pans you might grow some of that brain back..

Comparison of the regional distribution of transferrin receptors and aluminium in the forebrain of chronic renal dialysis patients. - PubMed - NCBI
Nawww. Don't think it's stupidity in my case. More CURIOUS and ANALYTICAL than a member of the easily panicked herd.
Let's start here -- The study you produced was done on people with kidneys SO FAR GONE that they required "chronic dialysis". So, that's not a measure of how much Alum. sticks around from ingestion. Which maybe in the range of 1% or less. And as it turns out -- the ONLY verifiable Alzheimer deaths due to "aluminum poisoning" are less than 5. One a man who WORKED in a hazardous Alum dust enviro. One a women who's municipal water supply had HIGH levels of NATURALLY occurring ALum..
So -- the "foil" risk is just a SMALL FRACTION of the concerns when considering how the body inhales or digests FOOD PRODUCTS containing aluminum. For instance, if you are a cook or a baker -- and I am --- I KNOW that many leavening agents show Alum components right on the damn pkg. To wit....
Aluminium content of selected foods and food products
Aluminium is the third most abundant element in the earth's crust and is therefore a natural component of drinking water and foodstuffs and is a component of many manufactured materials. Exposure of the human body to aluminium may be by food [1, 2, 3, 4, 5, 6, 7, 8] including drinking water, fruit juices wine and beer [9, 10, 11], articles of daily use that are made of aluminium, cosmetics and pharmaceuticals such as local therapeutic agents, anti-diarrhoeal drugs or antacids. Increased aluminium exposure can be compensated for by excretion via intestines and normal, healthy kidneys. Kidney insufficiency was shown to result in increased aluminium concentrations in the kidneys of dialysis patients, possibly resulting from dialysis fluids that may contain substantial concentrations of aluminium [12].
For many years, aluminium was not considered a health threat because of its relatively low bioavailability. In 1965, however, animal experiments suggested a possible connection between aluminium and Alzheimer's disease, whereby aluminium salts were injected directly into rabbit brain where they caused tissue alterations (for a review see [13]). Increased aluminium concentrations were found in the brains of deceased Alzheimer's patients. Other studies, however, have been unable to find definite indications supporting the hypothesis that aluminium plays a causative role in Alzheimer's disease or causes pathological alterations in vivo in the species studied [14, 15, 16, 17, 18, 19, 20].
In the 1970s, the issue of toxicity of aluminium gained importance after Berlyne et al. (1970) reported on increased aluminium concentrations in the serum of nephropathic persons [21]. The findings of Alfrey et al. [22] increased concerns about an increased oral intake of aluminium since these findings were the first to establish a connection between neurologic diseases of dialysis patients and an increased intake of aluminium in the organism. In a more recent study aluminium is also discussed as as an endocrine disruptor in female Nile Tilapia (Oreochromis niloticus) [23].
Food is unquestionably the main source of aluminium intake, whereby the source is considered either primary or secondary. The primary content is the natural content of food caused by uptake from the geologic surrounding during growth and is for all practical purposes unavoidable. The secondary content is the primary content plus any possible contamination from aluminium articles that come into contact with food and additives as well as veterinary drugs, fertilisers and the air. Table 1 shows the main, permissible secondary aluminium sources that may lead to an aluminium accumulation in food.
Check out the FOOD table in that article to see how "herbal teas" cocoa powder, baked goods and other common foods, food additives, vaccines, and enviro exposure to common stuff --- BESIDES Alum foil is actually a part of this concern..
Then cruise over to WebMd (aluminum toxicity Alzheimers) and read about all the studies that DID NOT SHOW aluminum toxicity as a suspect cause...
It's "unsettled science" --- As MOST of science is..
Unsettled science still doesn't mean that all theories have equal validity. This is more in the category of accepted science, meaning the leading authorities are comfortable with the finding even if every potential aspect is not, and possibly will never be known.
And "what finding" would that be? Especially, if there's no effort to establish min safe exposure levels or QUANTIFY the exact risk for Alzheimers and the other "postulated" outcomes?
No findings -- no "accepted" science. Just gathering empirical evidence on "causality" and attempting to identify the possible "vector sources" for the theory.
Did ya go the WebMD site? Probably not..
Controversial Claims About the Causes of Alzheimer's Disease
One of the most publicized and controversial theories concerns aluminum, which became a suspect in Alzheimer's disease when researchers found traces of this metal in the brains of patients with Alzheimer's disease. Many studies since then have either not been able to confirm this finding or have had questionable results.
Aluminum does turn up in higher amounts than normal in some autopsy studies of Alzheimer's patients, but not in all. Further doubt about the importance of aluminum stems from the possibility that the aluminum found in some studies did not all come from the brain tissues being studied. Instead, some could have come from the special substances used in the laboratory to study brain tissue.
Aluminum is a common element in the Earth's crust and is found in small amounts in numerous household products and in many foods. As a result, there have been fears that aluminum in the diet or absorbed in other ways could be a factor in Alzheimer's. One study found that people who used antiperspirants and antacids containing aluminum had a higher risk of developing Alzheimer's. Others have also reported an association between aluminum exposure and Alzheimer's disease.
On the other hand, various studies have found that groups of people exposed to high levels of aluminum do not have an increased risk. Moreover, aluminum in cooking utensils does not get into food, and the aluminum that does occur naturally in some foods, such as potatoes, is not absorbed well by the body. On the whole, scientists can say only that it is still uncertain whether exposure to aluminum plays a role in Alzheimer's disease.

Does aluminum play a role in causing
Alzheimer’s disease?
Thinking about whether aluminum plays any role in
Alzheimer’s disease has evolved over the 40 years that
researchers have been exploring this question. The theory
that aluminum might be involved emerged in the 1960s
after scientists discovered that exposing rabbits’ brains to
aluminum caused nerve cell damage with some similarity to
Alzheimer pathology. Physicians also noted that people
undergoing long-term dialysis sometimes develop a nonAlzheimer
form of dementia caused by a buildup of
aluminum in the bloodstream. These observations raised
the specter that aluminum might be one of the first
substances implicated in triggering Alzheimer’s.
However, studies since then have failed to document a
clear role for aluminum in causing Alzheimer’s. Every
perspective from which researchers have explored the
question has yielded contradictory data. For virtually every
study suggesting that aluminum may be linked to
Alzheimer’s, there is another study failing to confirm
those results.
The vast majority of mainstream scientists now believe that
if aluminum plays any role at all in Alzheimer’s, that role is
small. If aluminum exposure had a major impact on risk,
scientists would have gained a clearer picture of its
involvement over the decades that they have been studying
the issue, even though certain factors hamper research. One
such issue lies in the widespread occurrence of both
aluminum and Alzheimer’s, which complicates the effort to
characterize their relationship. Aluminum is Earth’s third
most common element after oxygen and silicon, and
Alzheimer’s occurs frequently in older adults.
.........
Further, it is unlikely that people can significantly reduce their exposure to aluminum through such measures as avoiding aluminum-containing cookware, foil, beverage cans, medications and other products. Even if aluminum were clearly implicated in Alzheimer’s, these routes of exposure account for only a small percentage of the average person’s intake.
I've got another source on this -- my daughter, who has worked in 2 of the top US research labs on Alzheimer's in the past few years. And we've had long discussions about the "elevated number" and enviro issues. And there's a LOT of theories. But not a lot of "settled or "consensus" science on this theory about metals.
Not even CONSENSUS science at this point. Not likely to BE SETTLED science in the near future.

Wow. Electron Microscope pix. How cool.. Still -- the increase from cooking meats is very dependent of the spicing, time, temperature, acidity of the marinade or sauces. And that SAME paper shows that MOST of the results only doubled or tripled the NATURAL aluminum content of the food. So HOW MUCH you ate of a marinated steak NOT cooked on foil -- could outweigh a smaller portion cooked on foil. So what? Until you have a CONNECTION to a specific med condition -- the caution should be for folks on constant dialysis -- with no natural kidney function. And those folks have a whole ENCYCLOPEDIA of stuff to worry about already..
