If you’re like most people, you grew up using aluminum foil. Your mom used it for cooking, to wrap your sandwiches for school and to store left-overs at home. You probably still use aluminum foil in your home because it’s so versatile. It’s only been a few years since I stopped using it but before that I would buy it in bulk at Costco. I used it for everything, from baking and grilling to storing things.
But when you know better, you do better, right? Aluminum foil is not the safest product and they are plenty of other alternatives you can use instead that are just as effective without posing a threat to your health.
So, why is aluminum foil so bad?
Aluminum is a neurotoxic heavy metal that has been linked to health issues, such as Alzheimer’s disease as well as malfunction of certain parts of your brain: memory decline, loss of coordination and body control.
The biggest concern with aluminum is that it builds up in your bones and can take the place of calcium, deteriorating your bone quality. People with too much aluminum in their bones will show high levels of calcium in the blood because that calcium is not deposited in the bones. This inhibits bone mineralization, resulting in osteoporosis.
The good news is that our bodies can process some of this aluminum and get rid of it. According to the World Health Organization, it is considered safe to intake about 40mg of aluminum per kilogram of body weight. However, if you have kidney issues that’s another story and an even bigger reason to avoid anything with aluminum, including aluminum foil.
The bad news is that aluminum is everywhere and we come in contact with it through many different ways. You can also find aluminum in antacids, astringents, buffered aspirin, food additives, antiperspirants and cosmetics. Aluminum has been also found on kitchen utensils, pots and pans and even on some packaged foods.
It accumulates in our body so minimizing exposure it’s very important for the overall health of our bodies.
Aluminum leaches into your food
Aluminum doesn’t seem to leach if you use the foil just to wrap food (I personally err on the side of caution and don’t use even for that). However, the biggest problem comes from cooking with aluminum foil. The higher the temperature you cook in, the more aluminum leaches into your food and you don’t want that.
All I can think about is the potatoes I used to grill a few years ago. The aluminum foil practically came apart from all the cooking. I’m mortified to think I was eating aluminum filled potatoes. But we can’t get stuck on what we did in the past, we have to minimize our exposure from now on.
Acidic foods can also make the aluminum leach into your food. Avoid using it around citrus, tomatoes and spices. Even if you’re only wrapping your food in aluminum foil and not cooking with it because these foods will make the foil leach aluminum straight into your meal.

How do I minimize aluminum exposure?
The best thing you can do is avoid aluminum as much as possible. Keep in mind you won’t be able to avoid exposure all together because it’s everywhere but by taking it out from your kitchen and food preparation you’re minimizing a great deal of unnecessary aluminum exposure.
Here are the three things you should do now:
- Get rid of you aluminum foil. If you must use it, do not use it for cooking and don’t store tomatoes, citrus nor spices in it.
- Replace aluminum pots and pans. Keep in mind a lot of aluminum pans are coated so the aluminum doesn’t leach into your food, at least not right away. With prolonged use this coating can come off and because we use them with high heat your chances of aluminum leaching into your food are greater. You’re better off not owing any aluminum pots and pants. These are the safest pots I’ve found – read this post to learn more about safer cookware.
- Don’t buy aluminum kitchen utensils. There are bamboo, wooden, stainless steel and glass alternatives. Most of them are really affordable and don’t expose you to this neurotoxin.
- Use a water filter that filters out aluminum. This is the one we use. Read this post for more information on water filters.
What can I use instead of aluminum foil?
We have replaced aluminum foil in different ways:
- For storing food: we use glass storage containers.
- For baking we use: glass, ceramic, stainless steel when it comes to muffin pans and this parchment paper.
- For grilling: we just used the grill as iS but when we’re grilling smaller pieces of vegetables we use this grill basket.
As you may have concluded, we’re just better off avoiding aluminum foil for the sake of our health. Why expose ourselves to something that can cause complications when it can be avoided? Since there are so many other safer alternatives we can use, there’s no reason to keep using aluminum foil at all.
Have you ditched aluminum foil yet? If not, this is the time, and even more so if you have little ones at home!
