Removing aluminum from food after cooking can be challenging as it may have already been absorbed or integrated into the food. However, you can minimize aluminum exposure by using non-aluminum cookware and avoiding processed foods with aluminum additives. If aluminum is suspected in the food, consider discarding it. To reduce aluminum in the diet, opt for fresh, whole foods and cook with stainless steel, cast iron, or glass cookware. Regularly changing cooking utensils and avoiding acidic foods in aluminum cookware can also help reduce aluminum exposure.
