Aluminum Foil Uses and Health Risks

Nowadays, aluminum foil is used in almost every household. Be it wrapping leftover rotis, covering vegetables or packing tiffins, aluminum foil is considered to be the most convenient and fastest option. Due to its mild nature people consider it safe. But have you ever thought that this convenience can be harmful for your health?

Many researches in recent years have indicated that excessive and incorrect use of aluminum foil can be harmful to health. In particular, when hot food is kept in it or stored for a long time, it can increase the amount of aluminum in the body.

Research findings

A study published in the Food Bioscience Journal in December 2024 shocked people. This study found that when fish was roasted in aluminum foil at high temperatures, metals from the foil passed into the fish. According to researchers, the more foil was used, the greater the amount of aluminum found in the food.

Another study tested the effects of aluminum foil during baking. It included many food items like salmon, mackerel, chicken, pork, tomatoes and cheese. The results revealed that the amount of aluminum in these foods increased by forty times. This information is especially important for people who regularly cook or store food in foil.

Expert advice

Doctors believe that misuse of aluminum foil and utensils can pose a serious threat to health. According to experts, aluminum reacts quickly with sour, salty and spicy foods. This reaction occurs more in foods like tomato, lemon, vinegar, pickles and gravies.

When such foods are wrapped in aluminum foil or stored in aluminum utensils, the metal can leach into the food. This process gradually causes aluminum to accumulate in the body.

Raipur’s famous oncologist and cancer surgeon Dr. Jayesh Sharma has also warned people on this subject. In a video shared on social media, he said that it is not safe to wrap hot roti or hot food in aluminum foil. Doing this for a long time can have negative effects on the kidneys.
