What Happens to Your Body When You Cook with Foil?

8. Risks of Wrapping Hot Bread and Sandwiches
Many bakeries or restaurants wrap very hot bread or sandwiches in aluminum sheets immediately. The steam generated by the heat moistens the surface of the foil, facilitating the transfer of particles to the bread. This seemingly hygienic storage method can be a hidden pathway for aluminum to enter the daily diet. Health Hazard: Daily consumption of warm bread wrapped in foil can cause mild inflammation in the intestinal and stomach linings.
