What do we mean by cast aluminum?
Cast aluminum is a type of cookware that is made by pouring molten aluminum into a mold. The mold is then cooled and the aluminum takes on the shape of the mold. Cast aluminum cookware is often used for its ability to conduct heat quickly and evenly.
Commonness
According to a recent survey, roughly 60% of home cookware currently sold in the US is made of aluminum. This is due to aluminum's affordability and its ability to conduct heat well. In fact, most high-end cookware brands now offer aluminum cookware as part of their product lines.
Relative non-accumulation
There has been a lot of discussion in recent years about the safety of aluminum cookware. Some people are concerned that aluminum can accumulate in the body over time and potentially cause health problems. However, the scientific evidence suggests that this is not a significant concern.
Aluminum is a very common element in the Earth's crust, and we are exposed to it every day through our water, food, and the air we breathe. Our bodies are able to handle small amounts of aluminum without any problems. In fact, the average person consumes between 10 and 30 mg of aluminum each day through their diet and the water they drink.
Scientific evidence
1. Does aluminum leach out of modern cast aluminum pans?
One of the main concerns people have about aluminum cookware is that it can leach into our food during cooking. However, modern cast aluminum cookware is typically coated with a non-stick material that prevents aluminum from leaching into food.
Furthermore, research has shown that even in cases where small amounts of aluminum do leach into food, this is not likely to cause harm to our health. A study published in the Journal of Alzheimer's Disease found that aluminum intake from cookware was not associated with an increased risk for Alzheimer's disease or other neurological disorders.
2. If aluminum leaches into our food from our aluminum pans, is it dangerous?
Aluminum is not considered to be a toxic substance, and there is no evidence that the small amounts of aluminum that might leach into our food during cooking pose any significant health risk. In fact, the FDA has not set any limit on the amount of aluminum that is allowed in food.
In conclusion, cast aluminum cookware is a safe and affordable option for home cooks. When used correctly and maintained properly, it can last for many years and provide excellent cooking performance. While there are some concerns about aluminum leaching into food, the scientific evidence suggests that this is not a significant health risk. As always, it's important to follow safe cooking practices and to use all cookware according to the manufacturer's instructions.
