关于蔬菜的英语演讲稿
Dear leaders and teachers, good evening! I am very happy and uneasy to go to this platform. I'm glad to have such a good opportunity to speak freely with my colleagues; I am worried about my image and the topic of today's speech, the nutrition of vegetables
1. Vegetables contain a lot of water, usually 70% - 90%, in addition to a small amount of protein, fat, sugars, vitamins, inorganic salts and cellulose. Vegetables contain a variety of minerals, vitamins and food fiber, which play an important role in human physiological activities.
2. Vegetables can provide the main vitamins folic acid, carotene and B vitamins. The contents of vitamin C, carotene and folic acid were higher in dark leafy vegetables such as yellow, red and green.
3. The mineral content of green leafy vegetables is very rich; However, the oxalic acid in some vegetables (amaranth, spinach, macaroni, etc.) will affect the absorption of minerals by the human body. Therefore, when cooking these vegetables, you should blanch them with boiling water to remove the oxalic acid. Experts suggest that adults should eat 500 grams of vegetables a day, of which 2 / 3 are leafy vegetables and 1 / 3 are melons, fruits and rhizomes.
译文:尊敬的各位领导、各位老师： 晚上好!我很高兴也很忐忑走上这个讲台。高兴的是又有这么好的机会和同事们一起畅所欲言；忐忑的是自己的形象与今天演讲的主题蔬菜的营养
1、蔬菜中含有大量水分，通常为70％～90％，此外便是数量很少的蛋白质、脂肪、糖类、维生素、无机盐及纤维素。蔬菜含有多种矿物质、维生素和食物纤维，在人体的生理活动中起重要作用。
2、蔬菜可提供的维生素主要叶酸、胡萝卜素以及B族维生素等。其中维生素C、胡萝卜素、叶酸在黄、红、绿等深色叶菜中含量较高。
3、绿叶蔬菜的矿物质含量很丰富；但某些蔬菜（苋菜、菠菜、通心菜等）中的草酸会影响人体对矿物质的吸收，故烹调这些蔬菜时，应先用开水漂烫，以去除草酸。专家建议，成人每日宜摄入500克蔬菜，其中2/3为叶菜，1/3为瓜果和根茎类。
