Will a cast-iron pot enameled only on the outside leach some dangerous stuff into the food?
I want a plain one, without enamel, but they are difficult to find.
Also, I have read that a deficiency of iron in the diet of modern people is common and using cast-iron helps to increase the store of this nutrient, although vegetarians do not usually have a deficiency as they consume lots of greens and lentils, for instance. The recommended iron intake for adult women is 18 mg per day. However, it is advised that those people who have gone through menopause should not take iron supplements or multivitamins containing iron unless a doctor specifically recommends it, so I am wondering if older people should be cooking their food in cast-iron pots at all? The reason is not quite clear why older people should not up their iron intake, maybe it is because of the risk of heart disease or cancer, or somehow the older body is less efficient in getting rid of the excess? The transfer of iron to food seems to be quite high when using cast-iron cookware - scrambling eggs in a (new) iron skillet, for example, increases the iron from 1.5 mg to about 5 mg, and applesauce goes from less than half a milligram to about 7 mg!
