The city health department unveiled(明らかにした)a proposal that would prohibit cooks at New York City's 24,600 food service establishments from using ingredients that contain artificial trans fatty acids(トランス脂肪). The artery-clogging(動脈を詰まらせる)fats, which are commonly listed on food labels as partially hydrogenated(水素添加された)oil, are present in some shortenings , margarine, and frying oils and are found in foods like french fries(フライドポテト)and doughnuts. In Chicago, a similar proposed ban on trans fats has been protested by some who see it as unnecessary government meddling(干渉).
