Aluminum foil is a household staple, commonly used for cooking and food storage. But have you ever wondered about the health implications of using aluminum foil? We have done the research and are here to help you navigate the pros and cons, health risks, and safe alternatives for using aluminum foil in your kitchen.

Which Side of Aluminum Foil Should You Use?

When using non-stick foil, be sure to place your food on the side that has a dull, flat finish; this information is often found on the product packaging. For regular and heavy-duty foil, either side can be used for cooking, according to experts.

Is Aluminum Foil Safe for Oven Cooking?

Aluminum is a metal that naturally occurs in our environment and can be found in small amounts in our bodies. If ingested in small amounts, it’s generally considered safe, as our bodies are capable of excreting it. However, using aluminum cookware and foil can sometimes lead to contamination of food. A protective layer usually prevents this, but over time it can wear away.

Aluminum has been found in high concentrations in the brain tissues of Alzheimer’s patients. Therefore, experts recommend limiting the use of aluminum utensils, especially at high temperatures, as this can cause leaching.

Symptoms of Excessive Aluminum Consumption

  • Confusion
  • Muscle aches
  • Kidney failure
  • Bone pain
  • Physical deformities

Potential Health Risks of Aluminum

Although the amount of aluminum exposure through food and cooking is generally considered safe, some studies have suggested that excessive dietary aluminum may be a risk factor for Alzheimer’s disease and inflammatory bowel disease (IBD).
