Aluminum Foil Is Not Safe?`

Answered on August 19, 2014
Created July 02, 2012 at 12:15 AM

So, I was telling a friend how I wrap my sweet potatoes in aluminum foil before I put them in the oven. Why do I do this? Because that's how I've always seen my mother do it. I never really thought about it and the sweet potatoes come out so nice and juicy.

Anyhow, my was telling me that the aluminum leaches into the food when you cook with it like that? I didn't think so....Am I wrong?

Don't forget to prick the potatoes all over before placing on the oven rack! I made a potato bomb once....

The only downside, I assume, is that you might wanna check your iron (ferritin) level due to iron absorption?

Cast iron sounds like it would taste better and be easier.

I know that aluminum (abstractly) has been linked with Alzheimer's, but as yet there is no connection directly between aluminum cookware and prevalence of Alzheimer's. Still, something to consider...

By baking dish, do you mean Pyrex?

It is so environmentally unfriendly. 'm not sure it really adds much either. It would be interesting to conduct an experiment with foil and without and see what the difference really is. I also use the microwave (I have yet to see any science to tell me I shouldn't) and they come out great. Or I cut them up and roast in duck fat.

I have 2 titanium pots that I love. I save up and I buy one once a year at the home show. I'll havevto look for a baking dish.

I use baking dishes with covers. Just put it in the oven in a baking dish - even a small one and cover it. Same thing. I personally do not use aluminum, just don't like the feel of it. I only use enameled cast iron or white baking dishes.

Yep, microwaving (isn't that another can of worms?) is much much faster. Though I've been known to simply bake them on the oven rack without a foil wrap.

Thanks. I did see this link, but I wasn't sure if an aluminum pan would be the same thing.

Unlikely to be a problem with sweet potatoes. Aluminum leaches out with acid, and sweet potatoes aren't acidic. Contact is another factor. If you're baking whole sweet potatoes in the skin, wrapping with aluminum foil and not eating the skin, the risk of leached aluminum is zero, probably more aluminum naturally occurring in the sweet potato than is added via the foil.

Agree with Matt above, but I don't like to use foil because it seems so environmentally unfriendly. I actually pierce my sweet potatoes and zap them in the microwave. Three minutes on a side is much quicker than cooking in oven.

You can place potatoes right on the oven rack wrapped in absolutely nothing. They come out just fine.

Also agree about the acidity issue. If you've ever covered a dish of ziti or lasagna (in your pre-Paleo days) with aluminum foil, you may have seen it literally eroded away where it came in contact with the tomato sauce. Yikes! I think it's okay to wrap more "plain" stuff in for the fridge.

I agree that the risk of aluminum leaching is very minimal, especially if you don't eat the skin. As to cooking method, I think the difference between wrapping them in foil and putting them directly on the rack (pierced a few times so they don't explode) is that wrapping them in foil would technically steam the potatos as opposed to baking them. In end product you would end up with softer skin with steamed, and crispier with baked.

the only reason I've been considering foil is to prevent the leaking all over the racks and below. I don't care for how 'rubbery' they get cooked in the microwave.

So what's better when it comes to cooking steak? Using a cast iron frying pan (frying isn't too good?) vs. broiling in an electric oven with an aluminium foil covered oven tray? Beef is quite acidic and I see beef juice and tallow actually boiling on the foil at 300F.
