@Lolinaa - Lolina seems like a nice Italian name. Are you living in Italy? If so, is it true that people in Italy are generally lean?Actually, here there are more and more enriched food like in America and the flour is too.
The difference is that you can still find some healthy options without ruining yourself unlike America.
In France and Italy people eat lots of bread, pizza, pasta and crêpe. I dont think the bakeries and supermarkets use iron free floor to do their bread and pastries.
And when I see the lack of energy and the crazy way people are acting here I definitely think there is something with the food.
