There are some variety about the issue. Some says ignorable some days unhealthy. Have a look that site please https://www.healthline.com/nutrition/aluminum-foil-cooking
The internal aluminum load is measured in terms of the concentration of aluminum in urine and blood. Keeping these concentrations below the tolerance values prevents the development of manifest and subclinical signs of aluminum toxicity. Large-scale epidemiologic studies of the relationship between aluminum-containing antiperspirants and the risk of breast cancer would be desirable.

Acidic foods cooked in anodized aluminum do not react with the cookware, and most authorities believe that anodized aluminum cookware is safe. At this time, there is no evidence to the contrary.
Aluminium wraps have been used for a long time for food wrapping. However, there are certain manufacturers who follow the regulations for food grade packaging. Some manufacturers who compromise on the cost expose the customers to higher dosages (improper manufacturing techniques)of aluminium, thereby causing hazards. So, it is the consumers' choice to prefer a safer product.
In short: While untreated aluminum is not unsafe, it should not be used with acidic foods, which may ruin both the food and the cookware. Our favorite rimmed baking sheet is made out of aluminum and perfectly safe to use, but avoid cooking acidic foods on it.
There are some inconsistencies in the answers of various studies have found studies to support that Alzheimer's is caused by increased levels of aluminum in the brain and therefore people began to question the safety of aluminum cans and aluminum kitchen appliances because they may put them at risk of Alzheimer's.
On the other hand, research has shown that aluminum poses no risk to Alzheimer's disease. Despite the consensus of the medical complex on this subject, there are many skeptics consider aluminum as a toxic substance, according to the CDC. If it is not the cause of Alzheimer's, it leads to other symptoms and risks. Especially when cooking acidic foods such as tomatoes in aluminum pots because it leads to a person's consumption to higher levels of aluminum and it is better to use another type.
Safety of aluminium usage in food wrapping and packaging is directly related to the fabrication process of this product. Aluminium foils have two sides, both containing aluminium. One of them is not covered/treated with a transparent protective film that circumvents the possibility of aluminium migration from the foil to food or other stuff wrapped by the foil. Conversely, the other side of the aluminium foil has this protective film and is this side that should wrap the goods.
Regarding live systems, several studies demonstrated a linkage between aluminium contamination/ingestion and the occurence of certain types of cancers, namely breast cancer.
