The foil is very convenient to bake meat, fish and vegetables, but the aluminum portion of it gets into the food - but it is harmful to health.
The effect of aluminum on health
Our body quietly takes a small amount of aluminum. According to the World Health Organization, safe dose aluminum consumption - 40 mg per 1 kg of body weight per daySafety evaluation of certain food additives and contaminants. .
But usually in the body it gets a lot more aluminum. It is found in corn, cheese, salt, spices, tea. Aluminum doing the dishes, it is used in medical products (in antacids) and antiperspirants. Aluminum sulphate is used in the purification of drinking water.
The researchers concludedRisk Assessment of Using Aluminum Foil in Food Preparation. That excessive consumption of aluminum can harm health. Furthermore, aluminum may be harmful to people with bone disorders and renal dysfunctionComparison of the regional distribution of transferrin receptors and aluminium in the forebrain of chronic renal dialysis patients. .
Aluminum falls in food
Pots and other utensils made of aluminum oxidize: they formed oxide film, aluminum does not give fall into the food. The problem is that while we wash to clean off the protective layer. To avoid this, boil a few times in a new aluminum pan water until the bottom of the wall and will not be dull.
Of course, with the foil so it can not be done. Therefore, during the cooking of food in it gets more aluminum, much higher than the permissible normRisk Assessment of Using Aluminum Foil in Food Preparation. . Especially a lot of aluminum falls in food if used aggressive ingredients: lemon or tomato juice, alcohol - all of which can partially dissolve the foil.
Therefore, researchers are advised to abandon the use of aluminum foil and baking a glass or ceramic dish. Cold food can also be wrapped in foil, but do not keep it too long, especially if it is acidic or spicy.
