Yes commercial side does not have the incentive to avoid health issue causing practices until there is government regulations for it. Companies choose the cheapest products where it does not matter.

I have said to one restaurant that they should not serve food in aluminum dishes. They changed their practices almost immediately.

Aluminum foil is considered safe when used normally. Excess amounts might be problematic. Leeching happens mostly in high temperatures when in contact with acidic food.

"For aluminum welders and workers in the aluminum industry, declining performance in neuropsychological tests (attention, learning, memory) has been found only with aluminum concentrations exceeding 100 µg/g creatinine in the urine"

"Creatinine Levels in Urine According to the University of Maryland Medical Center, the normal range of creatinine in a 24-hour urine sample is 500 to 2,000 mg a day."

So if you have a normal level of 1g of creatinine in your urine, you would need to ingest 0.1mg of aluminum daily. Your pot would dissolve 36.5mg per year or 365mg in 10 years.

Since not all of the aluminum gets absorbed the actual numbers are probably 10x larger.

I'm a med student so I have access through my uni.

Highlights:

• This meta-analysis included 8 cohort and case control studies, with a total of 10567 individuals.

• Two main types of chronic Al exposure are reported: Al in drinking water and occupational exposure.

• This meta-analysis shows that chronic Al exposure is associated with 71% increased risk of AD.

This seems to be incorrect. According to the 2015 meta study, risk of Alzheimer’s increases 71% for people who have had a long exposure to Aluminum during their life:

In otherwords: do not worry about occational exposure to aluminum for example when using aluminum foil. Chronic exposure might slightly (71%) increase you chances of getting Alzheimer’s disease.

Highlights from the 2015 meta study linked to the snoops:

• This meta-analysis shows that chronic Al exposure is associated with 71% increased risk of AD.

I did read it. Anyone interested should definitely read it too. I think that that line just put it nicely. Alzheimer’s is not caused by aluminum. There is a possibility that it might have some role in it.

You need to get quite a lot of aluminum to reach toxic levels:

"For aluminum welders and workers in the aluminum industry, declining performance in neuropsychological tests (attention, learning, memory) has been found only with aluminum concentrations exceeding 100 µg/g creatinine in the urine"

"Creatinine Levels in Urine According to the University of Maryland Medical Center, the normal range of creatinine in a 24-hour urine sample is 500 to 2,000 mg a day."

So if you have a normal level of 1g of creatinine in your urine, you would need to ingest 0.1mg of aluminum daily. Your pot would dissolve 36.5mg per year or 365mg in 10 years.

EDIT: Since not all of the aluminum gets absorbed, the actual numbers are probably atleast 10x higher.

Cast iron is probably much heavier. This probably gives a bit of an metallic taste especially to acidic food.

It does take time for science to fix the incorrect beliefs, that is true. I do not want to be testing aluminun on myself and I just wanted to share my (partially outdated) knowledge of aluminum and its health concerns.

There was a snoops link in this threat that said:

"The available data do not suggest that aluminum is a causative agent of Alzheimer’s disease; however, it is possible that it may play a role in the disease development."

You can read that as you like. I like to try to avoid chemical exposure when it is easy to do and avoiding aluminum in cookware is one case. Apparently the obvious toxic levels are well above what you would ingest from daily cooking.

With all the possible interactions between the thousands of safe chemicals in our daily life, I feel like it is just much safer to avoid exposure when it is convenient.

Thanks for the link. This was an interesting take from it:

"The available data do not suggest that aluminum is a causative agent of Alzheimer’s disease; however, it is possible that it may play a role in the disease development."

There are a number of coating alternatives to choose from.

Did your grandma get dementia when getting old? Apparently aluminum accumulates in kidneys, brain, lungs, liver and thyroid so when it leeches to your daily food, it can cause varying health issues after decades of use.

Yes there are surface coatings that prevent exposure to the aluminum.

I bet you wont find modern aluminum cookware without some surface coating. It is for a reason that it is not used anymore.

It is an aluminum alloy. Not safe for cooking unfortunately.

"Magnalite roasters were cast of an alloy of 94.2% aluminum, 2.5% copper, 0.5% zinc, 1.3 manganese, and 1.5% nickel"

Yeah I would not use these for cooking. Aluminum is not food safe according to modern standards.

I felt good after getting in one of these companies. I'm still enlisted there but I never landed a customer gig there since they were not interested in paying what I'm used to (I can put my own price on their portal). I've had a couple of customer interviews during the 3 years but I've been more successful finding my own customers.

The interview was definitely not the best experience but not the worst either. It does measure your knowledge of some of the common tools used in the industry and puts emphasis in the most common tools.

Consulting companies usually wants to produce value for the customer as fast as possible without thinking too much if the details. This might push them towards their method of choosing who to hire.
