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 ].
There are about 8 million people in Switzerland. About 64% of the people speak German as their first language, in northern and central Switzerland. 19% of the people speak French as their first language, in the west of Switzerland. 8% of the people speak Italian, in the south of Switzerland. Only 1% of the people speak Romansh, in the southeastern part of Switzerland.
I believe most Swiss do speak some English as well though. While officially the languages they speak are called German, French and Italian, they actually speak different versions of those languages, known as Swiss German, Swiss French and Swiss Italian. There is a fourth language, known as Rumantsch or Romanesc.
