There are some concerns regarding the use of aluminum strips, particularly in the context of cooking utensils and food packaging. Prolonged exposure to aluminum has been linked to potential health risks, including Alzheimer's disease, although the evidence is inconclusive. Aluminum can leach into food, especially in acidic environments, which may lead to increased aluminum intake. However, the FDA and other health authorities have not issued warnings about the use of aluminum cookware or food packaging, as the levels of aluminum typically ingested are considered safe. It's important to note that more research is needed to fully understand the potential health implications of aluminum exposure.
