Aluminum foil, which was first introduced in the early 1900s, is currently one of the most commonly used kitchen items. It is extremely versatile too, and is used for cooking, wrapping, and even for treating some common heath issues.
However, the problem with this kitchen item is its neurotoxic nature, which negatively affects the brain function and it was even found to trigger the onset of Alzheimer`s disease. As explained by medical expert, exposure to this metal may lead to mental decline and loss of memory, balance, bodily control, and coordination.
Additionally, it has been scientifically shown that cooking with aluminum foil impacts the bones, due to the fact that the metal accumulates in the bones and leads to loss of calcium which is of utmost importance for proper bone health. Cooking with aluminum foil was also found to cause pulmonary fibrosis and other respiratory issues.
When exposed to high temperatures through baking or grilling, the little bits of the metal end up in the food. Even if these tiny pieces are not released, adding certain spices or lemons may cause chemical leaching of aluminum.
Essam Zubaidy, a chemical engineering researcher at the American University of Sharjah, has done an extensive study which looked at the effects of aluminum on cooking. He found that a meal cooked in aluminum foil may contain up to 400 mg of aluminum.
“The higher the temperature, the more the leaching. Foil is not suitable for cooking and is not suitable for using with vegetables like tomatoes, citrus juice or spices,” he explains.
Specifically, this study showed that food items cooked in acidic solutions like tomato sauce or lemon juice basically took on the most aluminum. As mentioned above, adding spices increases the leaching even more. On the other hand, food items cooked in salt or alcohol took the least aluminum.
While the World Health Organisation states that 40 mg is the safe daily intake of aluminum, this study done by the researchers at the American University of Sharjah shows that the food wrapped in aluminum foil might contain more than 6 times that amount. Needless to say, ingesting this metal is such quantities is anything but safe.
To sum up, even though this simple tool is budget-friendly and helps prepare tasty meals, it is extremely bad for your brain, for your bones, and ultimately for your lungs. Therefore, if you would like to avoid brain-related issues, problems with your bones, and ending up with a pair of unhealthy lungs, make sure you stop cooking with aluminum foil.
