Are you still using aluminum pans in your kitchen? It’s time to find out about the safety of these pans. Aluminum can be found in pots, pans, foil, and even some drinking water. There are many concerns about cooking with aluminum, including how acidic foods react with the metal. Some say there is no risk, while others claim this is toxic for our food, causing reactions like Alzheimer’s disease or osteoporosis. Let’s take a closer look at what we know so far!
What are aluminum pans, and why are they used?
Aluminum pans are the resulting product created after molten aluminum is poured into a mold. Machining each pan from solid blocks of this metal was how early cookware makers could produce their products. But today, cast aluminum has become more popular for its durability and better functionality. Not only does it maintain better heat distribution than other materials like stainless steel do, Aluminum pots and pans also have an even surface that eliminates hot spots. This means making food taste better by maintaining moisture and its original flavors. Additionally, aluminum conducts heat better (16 times faster than steel), and it is relatively lightweight, making it easier to handle.
Are aluminum pans or cookware safe for cooking?
In short: Yes, aluminum cookware is perfectly safe to use.
While aluminum can leach into food from cookware, particularly from cooking acidic food, most aluminum cookware is designed to have a nonstick coating, anodized or stainless steel cladding. So you can be rest assured that even if the food does come into contact with the aluminum cookware, it’s unlikely for any toxins to leach through since these pans are lined with protective materials.
If you’re using plain aluminum pans, then it’s possible that cooking your food in them can increase aluminum intake. According to NCBI (National Center for Biotechnology Information) and a study published in the “Journal of Food Protection”, cooking in aluminum cookware can result in an insignificant increase in aluminum content – an amount that would not be sufficient to constitute a health hazard. Do note that research suggests an older plain aluminum pan may leach more aluminum than a newer one; however, the amount is still within acceptable levels given that most people would have natural aluminum intake daily that ranges from 1-10mg.
The myth that aluminum cookware causes Alzheimer’s has been debunked multiple times. This myth originated from discovering unusually high aluminum concentration in a deceased Alzheimer’s patient’s brain some decades ago. Since then, many renowned organizations like the Alzheimer’s Society and the FDA have reported that there’s no evidence for causation and usage of the aluminum product has any negative impact on health.
How to tell if your pan is made out of aluminum
If you’re wondering how to tell if your cookware is made out of aluminum, here are some useful indicators:
- Is it magnetic? The simplest way to determine if your cookware is NOT aluminum is with a magnet. Aluminum cookware will generate no magnetic attraction, unlike stainless steel.
- Stainless steel looks more bright and brilliant, while aluminum lacks that lustrous appearance, but it’s a lot more reflective and has lighter color.
- Aluminum is lightweight. It would be helpful if you had similar-sized cookware for weight comparison.
- The most accurate way is to look for the cookware brand and model and check directly with the manufacturer.
What are anodized aluminum pans?
Anodized aluminum pans are produced with aluminum that goes through an electrochemical process known as anodization. When exposed to air, aluminum will naturally oxidize to form a thin protective layer to prevent the metal from eroding. This layer of aluminum oxide is solid and durable, and essentially anodization is a process to develop a thicker layer of aluminum oxide. Due to its stable, non-reactive, and resistant properties, the resulting metal has twice as much strength as stainless steel.
From personal experience, an anodized aluminum pan is always a better option than plain aluminum pans. They are stronger, more durable, and have lower odds of leaching into the food even if the coating wears offs since the food will not be exposed to the core aluminum.
What shouldn’t you cook in aluminum pans?
It’s fine to cook anything if the aluminum pan is nonstick coated or anodized since the food will not directly contact the aluminum metal. However, if you’re using a plain aluminum pan, you might want to avoid cooking acidic food as it may react with aluminum and cause the metal to leach into the food. As mentioned, the additional aluminum intake is likely to be insignificant and doesn’t pose a health hazard. That said, it does change the food’s flavor (metallic taste) and may create pores on the pan’s surface. Some of the commonly used acidic foods are tomatoes, vinegar, and citrus.
Tips on maintaining your Aluminum pan
- Be sure not to leave any food residue on your aluminum pan for a prolonged period, as this could lead to accelerated coating degradation over time.
- Use warm water and gentle soap for cleaning these pans; do not use rough material that may scratch nonstick surfaces or harsh cleaners such as bleach.
- Use wooden or plastic cooking tools when cooking to prevent scratches.
- Storing your aluminum cookware properly is essential to prevent scratches and dents. Be gentle when retrieving the pan, as it may be bent or scratched more easily than stainless steel pans.
- Protect its surface with cloth lining during storage, especially if it has a nonstick coating.
Cooking with aluminum pans is a controversial subject, but science tells us there’s no need to avoid them. Aluminum cookware can be used safely in most cases, and anodized models are even better because they resist corrosion from acidic foods like tomatoes or wine. If you want your pan to last longer, make sure you wash it by hand and don’t leave residue food particles and grease for an extended period. If you’ve read this post in its entirety, you should have the knowledge necessary to make your own decision about what’s best for your cooking needs. Do consult with the manufacturer if you still have any doubts!
