All of us have used aluminium foil for wrapping food at least once, whether regularly or not, but definitely sometime. Aluminium foil is ductile, cheap and light-weight to touch. It is thus easy to manage.
Aluminium foil is clearly stronger than paper and less reactive to heat unlike plastic, but it has some demerits as well. Generally you cannot even imagine how harmful it is for our health. In this article, we will explore the uses of aluminium foil while also raising valid health concerns with respect to the same. Is aluminium foil dangerous? Let’s discuss further.
What Is Aluminium Foil and Why Is It Commonly Used?
Aluminium foil is a thin layer made of aluminium metal, which is made for the purpose of wrapping food. It is light, flexible, and protects your food from light and moisture. It is used for food packaging and preservation. It keeps the food from getting spoiled.
Due to its wide availability, affordable price and ease of use, it is widely used in households and the food industry. It is also used for reheating as it helps maintain the freshness of food. We also use it in baking to keep cakes, cookies, pizzas etc. fresh and to wrap them.
Is It Safe to Wrap Food in Aluminium Foil?
Generally, Aluminium foil wraps used for wrapping food are safe to use. Common usage includes cold storage or cooking at moderate temperatures. Considerable caution must be exercised when dealing with acidic or highly salty foods, though; citrus, tomatoes, or vinegar-based dishes, for instance.
These items can cause aluminium to leach from the foil into the food, hence posing certain health threats. Heating food wrapped in aluminium foil increases the leaching risk, in contrast to cold storage. Therefore, at present, we should focus on the alternatives to aluminium foil, which is good for our health and the environment.
Aluminium foil contains small amounts of aluminium metal, which is transferred to our body with the food. By repeatedly eating food wrapped in aluminium foil, we come in contact with a high amount of metal. This can cause many types of problems in our body.
Experts strongly advise against using aluminium foil in direct contact with intensely acidic or salty foods. For regular daily cooking and storing, go for alternatives such as glass containers or parchment paper to eliminate any risk.
Scientific Research & Health Impacts:
- According to Scientific studies, aluminium can leach into food in specific situations, mainly when food is acidic, salty, or cooked. Although the human body can usually process small quantities of aluminium effectively, excessive buildup affects bone integrity and neurological processes.
- Research attributes long-term high exposure to aluminium to health conditions like Alzheimer's disease. Regulatory bodies such as the World Health Organization and food safety authorities have set safe limits of consumption to ensure public health.
- Present evidence indicates that occasional cooking and storage using Aluminium foil is unlikely to be harmful if used correctly. Nevertheless, it's advisable to reduce exposure using safe cooking procedures and alternatives, such as glass containers or wax paper—so that undue aluminium ingestion may be prevented.
When is it safe to use aluminium foil?
When we use aluminium foil, it keeps a moisture balance in the food. It is used to wrap leftover food. You should also keep in mind not to wrap spicy or acidic foods, though. These react with the foil, and the taste may be altered. You should opt for eco-friendly food wrap whenever possible.
Aluminium Foil Safe uses:
- Oven cooking: You can wrap food to keep it moist or line trays for an easy cleanup.
- Grilling: Aluminium foil prevents food from falling through grates, locking in flavor.
- Food storage: You can wrap cool, non-acidic leftover foods for refrigeration or freezing.
- Baking: You can cover dishes to prevent over-browning or fashion them into custom baking molds.
-
Insulation: You can keep food warm for short periods.
Aluminium Foil Unsafe uses:
- Into the microwave: Its spark could be created, and fires may be set.
- On acidic foods: Things like tomatoes or citrus react with aluminium foil, which is risky.
- High heat for a long period: More aluminium will seep through into your food, and it will be dangerous for your health.
- Wrapping hot leftovers: Using aluminium foil, we trap steam and encourage bacterial growth.
-
Directly onto salty or spicy foods: Salt and spices can corrode the foil over time.
