Plants and iron-fortified foods contain nonheme iron only, whereas meat, seafood, and poultry contain both heme and nonheme iron [ 2 ]. Heme iron, which is formed when iron combines with protoporphyrin IX, contributes about 10% to 15% of total iron intakes in western populations [ 3-5 ].he richest sources of heme iron in the diet include lean meat and seafood [ 11 ]. Dietary sources of nonheme iron include nuts, beans, vegetables, and fortified grain products. In the United States, about half of dietary iron comes from bread, cereal, and other grain products [ 2, 3, 5 ].

Answers. 1  I've been to Switzerland and been to all the different parts of the country. It's really cool. The French spoken in Switzerland is actually called Romandie or Rumantsch (which is different than Standard French) and only about 20% of the population there speak this. French, Rumantsch, German and Italian are the other languages spoken in Switzerland. And English is apparenlty the 5th unofficial language.
