Professor Mikhail Kutushov, a Russian toxicologist, has warned about the dangers of using aluminum foil in cooking. In a statement to the website doctorpiter.ru, the professor notes that aluminum foil contains hormone-like substances that can cause hormonal imbalance in the human body. He states, "When these chemicals enter the human body, they 'disguise' themselves as female hormones—estrogen. When they accumulate, they lead to hormonal imbalance in the human body." According to him, these chemicals can disrupt thyroid function, contribute to obesity, and even cause cancer and other diseases. The professor also adds that this foil is harmful because it contains a high percentage of aluminum, reaching up to 90%. This element can accumulate in the kidneys, thyroid, and brain, causing various diseases.
