“家長進(jìn)課堂”活動

一年級二班.第一部分小學(xué)生食品安全

知識講座

.兩個(gè)問題同學(xué)們，你們知道什么是食品？什么是食品安全嗎？.所謂食品————就是吃的東西

.食品安全概念

食品安全是指食品無毒、無害，符合應(yīng)當(dāng)有的營養(yǎng)要求，對人體不造成任何危害。.講座基本內(nèi)容：

一、“垃圾”食品及其危害性二、培養(yǎng)良好的食品安全習(xí)慣三、常用食品采購小知識.一、垃圾食品及其危害性.

提到“垃圾食品”很多同學(xué)就會想到薯?xiàng)l、炸雞、可樂等，其實(shí)“垃圾”食品不光這些，還有其他很多食品。.十大垃圾食品你知道嗎？

.導(dǎo)致心血管疾??；含致癌物質(zhì)；破壞維生素。第一：油炸食品

.第二：腌制類食品

導(dǎo)致高血壓，腎負(fù)擔(dān)過重，導(dǎo)致鼻咽癌等。.第三：加工類肉食品

含致癌物質(zhì)：亞硝酸鹽；含大量防腐劑。.第四：餅干類食品

食用香精和色素過多,嚴(yán)重破壞維生素；營養(yǎng)成分低。.第五：汽水可樂類食品

含磷酸、碳酸，會帶走體內(nèi)大量的鈣；含糖量過高。.第六：方便類食品

鹽分過高；熱量過高，營養(yǎng)價(jià)值極低。.破壞維生素，使蛋白質(zhì)變性；熱量過多，營養(yǎng)成分低。第七：罐頭類食品

.第八：話梅蜜餞類食品

含致癌物質(zhì)：亞硝酸鹽，含防腐劑。.含奶油極易引起肥胖；含糖量過高影響正餐。第九：冷凍甜品類食品

.含大量致癌物質(zhì)三苯四丙吡，導(dǎo)致蛋白質(zhì)碳化變性。第十：燒烤類食品

.路邊攤點(diǎn).路邊攤點(diǎn)..垃圾食品對青少年的影響大量食用“垃圾食品”對兒童的智力、身高、發(fā)育會產(chǎn)生很大的影響。一份由相關(guān)科學(xué)研究所和青少年體質(zhì)與評價(jià)中心合作的抽樣調(diào)查顯示，66%的孩子身高不理想。.多吃油炸食品引起肥胖！.古語有云：病從口入

食品的質(zhì)量不安全，將會影響到人們的健康。食品的安全問題關(guān)系到同學(xué)們的生長、發(fā)育和健康成長。.第二部分二、培養(yǎng)良好的

食品安全習(xí)慣.養(yǎng)成良好的個(gè)人衛(wèi)生習(xí)慣

養(yǎng)成吃飯前洗手的衛(wèi)生習(xí)慣。生吃瓜果要洗干凈。不吃腐爛變餿的飯菜。飲水講衛(wèi)生，不喝生冷水。注意科學(xué)飲食。.標(biāo)準(zhǔn)洗手方法

1、掌心對掌心搓擦2、手指交錯(cuò)掌心對手背搓擦3、手指交錯(cuò)掌心對掌心搓擦.標(biāo)準(zhǔn)洗手方法

4、兩手互握互搓指背5、拇指在掌中轉(zhuǎn)動搓擦6、指尖在掌心中搓擦.盡量購買有下列標(biāo)志的食品.不要到無證、無照攤點(diǎn)上購買食品.到正規(guī)的大賣場、超市及標(biāo)準(zhǔn)化農(nóng)貿(mào)市場購買食品.

就餐選擇公示信息齊全的餐館.第三部分三、常用采購小知識

.掌握必要的檢查方法

視覺檢查——用眼睛看嗅覺檢查——用鼻子聞觸覺檢查——用手去摸味覺檢查——用嘴巴嘗.購買食品請看標(biāo)簽

食品標(biāo)簽必須標(biāo)注如下內(nèi)容：——食品名稱、配料表、凈含量及固型物含量——制造者的名稱和地址——生產(chǎn)日期及保質(zhì)期（保存期）——質(zhì)量等級、產(chǎn)品標(biāo)準(zhǔn)編號以及特殊標(biāo)注內(nèi)容等。.我們建議：

遠(yuǎn)離“垃圾食品”，保持科學(xué)、均衡的飲食習(xí)慣！.多吃健康食物！

.你能做到嗎？

不偏食、不挑食，養(yǎng)成良好的飲食衛(wèi)生習(xí)慣。.祝同學(xué)們健康成長！關(guān)注食品安全，享受健康生活！.感謝觀看/dx/sydxyy/8264.html/dx/sydxyy/8263.html/dx/bcdxyy/8262.html/dx/bcdxyy/8261.html/dx/bcdxyy/8260.html/dx/bcdxyy/8259.html/dx/bcdxyy/8258.html/dx/bsdxyy/8257.html/dx/bsdxyy/8256.html/dx/bsdxyy/8255.html/dx/bsdxyy/8254.html/dx/bsdxyy/8253.html/dx/lydxyy/8252.html/dx/lydxyy/8251.html/dx/lydxyy/8250.html/dx/lydxyy/8249.html/dx/lydxyy/8248.html/dx/thdxyy/8247.html/dx/thdxyy/8246.html/dx/thdxyy/8245.html/dx/thdxyy/8244.html/dx/thdxyy/8243.html/dx/spdxyy/8242.html/dx/spdxyy/8241.html/dx/spdxyy/8240.html/dx/spdxyy/8239.html/dx/spdxyy/8238.html/dx/hhdxyy/8237.html/dx/hhdxyy/8236.html/dx/hhdxyy/8235.html/dx/hhdxyy/8234.html/dx/hhdxyy/8233.html/dx/qthdxyy/8232.html/dx/qthdxyy/8231.html/dx/qthdxyy/8230.html/dx/qthdxyy/8229.html/dx/qthdxyy/8228.html/dx/jmsdxyy/8227.html/dx/jmsdxyy/8226.html/dx/jmsdxyy/8225.html/dx/jmsdxyy/8224.html/dx/jmsdxyy/8223.html/dx/mdjdxyy/8222.html/dx/mdjdxyy/8221.html/dx/mdjdxyy/8220.html/dx/mdjdxyy/8219.html/dx/mdjdxyy/8218.html/dx/ycdxyy/8217.html/dx/ycdxyy/8216.html/dx/ycdxyy/8215.html/dx/ycdxyy/8214.html/dx/ycdxyy/8213.html/dx/dqdxyy/8212.html/dx/dqdxyy/8211.html/dx/dqdxyy/8210.html/dx/dqdxyy/8209.html/dx/dqdxyy/8208.html/dx/jxdxyy/8207.html/dx/jxdxyy/8206.html/dx/jxdxyy/8205.html/dx/jxdxyy/8204.html/dx/jxdxyy/8203.html/dx/sysdxyy/8202.html/dx/sysdxyy/8201.html/dx/sysdxyy/8200.html/dx/sysdxyy/8199.html/dx/sysdxyy/8198.html/dx/hgdxyy/8197.html/dx/hgdxyy/8196.html/dx/hgdxyy/8195.html/dx/hgdxyy/8194.html/dx/hgdxyy/8193.html/dx/qqhedxyy/8192.html/dx/qqhedxyy/8191.html/dx/qqhedxyy/8190.html/dx/qqhedxyy/8189.html/dx/qqhedxyy/8188.html/dx/wzdxyy/8187.html/dx/wzdxyy/8186.html/dx/wzdxyy/8185.html/dx/wzdxyy/8184.html/dx/wzdxyy/8183.html/dx/zwdxyy/8182.html/dx/zwdxyy/8181.html/dx/zwdxyy/8180.html/dx/zwdxyy/8179.html/dx/zwdxyy/8178.html/dx/gydxyy/8177.html/dx/gydxyy/8176.html/dx/gydxyy/8175.html/dx/gydxyy/8174.html/dx/gydxyy/8173.html/dx/ycdxbyy/8172.html/dx/ycdxbyy/8171.html/dx/ycdxbyy/8170.html/dx/ycdxbyy/8169.html/dx/ycdxbyy/8168.html/dx/nxdxyy/8167.html/dx/nxdxyy/8166.html/dx/nxdxyy/8165.html/dx/nxdxyy/8164.html/dx/nxdxyy/8163.html/dx/gemdxyy/8162.html/dx/gemdxyy/8161.html/dx/gemdxyy/8160.html/dx/gemdxyy/8159.html/dx/gemdxyy/8158.html/dx/hbdxyy/8157.html/dx/hbdxyy/8156.html/dx/hbdxyy/8155.html/dx/hbdxyy/8154.html/dx/hbdxyy/8153.html/dx/hndxyy/8152.html/dx/hndxyy/8151.html/dx/hndxyy/8150.html/dx/hndxyy/8149.html/dx/hndxyy/8148.html/dx/hxdxyy/8147.html/dx/hxdxyy/8146.html/dx/hxdxyy/8145.html/dx/hxdxyy/8144.html/dx/hxdxyy/8143.html/dx/hddxyy/8142.html/dx/hddxyy/8141.html/dx/hddxyy/8140.html/dx/hddxyy/8139.html/dx/hddxyy/8138.html/dx/gldxyy/8137.html/dx/gldxyy/8136.html/dx/gldxyy/8135.html/dx/gldxyy/8134.html/dx/gldxyy/8133.html/dx/ysdxyy/8132.html/dx/ysdxyy/8131.html/dx/ysdxyy/8130.html/dx/ysdxyy/8129.html/dx/ysdxyy/8128.html/dx/xndxyy/8127.html/dx/xndxyy/8126.html/dx/xndxyy/8125.html/dx/xndxyy/8124.html/dx/xndxyy/8123.html/dx/qhdxyy/8122.html/dx/qhdxyy/8121.html/dx/qhdxyy/8120.html/dx/qhdxyy/8119.html/dx/qhdxyy/8118.html/dx/lndxyy/8117.html/dx/lndxyy/8116.html/dx/lndxyy/8115.html/dx/lndxyy/8114.html/dx/lndxyy/8113.html/dx/dxdxyy/8112.html/dx/dxdxyy/8111.html/dx/dxdxyy/8110.html/dx/dxdxyy/8109.html/dx/dxdxyy/8108.html/dx/qydxyy/8107.html/dx/qydxyy/8106.html/dx/qydxyy/8105.html/dx/qydxyy/8104.html/dx/qydxyy/8103.html/dx/jqdxyy/8102.html/dx/jqdxyy/8101.html/dx/jqdxyy/8100.html/dx/jqdxyy/8099.html/dx/jqdxyy/8098.html/dx/pldxyy/8097.html/dx/pldxyy/8096.html/dx/pldxyy/8095.html/dx/pldxyy/8094.html/dx/pldxyy/8093.html/dx/zydxyy/8092.html/dx/zydxyy/8091.html/dx/zydxyy/8090.html/dx/zydxyy/8089.html/dx/zydxyy/8088.html/dx/wwdxyy/8087.html/dx/wwdxyy/8086.html/dx/wwdxyy/8085.html/dx/wwdxyy/8084.html/dx/wwdxyy/8083.html/dx/tsdxyy/8082.html/dx/tsdxyy/8081.html/dx/tsdxyy/8080.html/dx/tsdxyy/8079.html/dx/tsdxyy/8078.html/dx/bydxyy/8077.html/dx/bydxyy/8076.html/dx/bydxyy/8075.html/dx/bydxyy/8074.html/dx/bydxyy/8073.html/dx/jcdxyy/8072.html/dx/jcdxyy/8071.html/dx/jcdxyy/8070.html/dx/jcdxyy/8069.html/dx/jcdxyy/8068.html/dx/whdx/8067.html/dx/whdx/8066.html/dx/whdx/8065.html/dx/whdx/8064.html/dx/whdx/8063.html/dx/whdx/8062.html/dx/zzdxb/8061.html/dx/zzdxb/8060.html/dx/zzdxb/8059.html/dx/zzdxb/8058.html/dx/zzdxb/8057.html/dx/zzdxb/8056.html/dx/hebdx/8055.html/dx/hebdx/8054.html/dx/hebdx/8053.html/dx/hebdx/8052.html/dx/hebdx/8051.html/dx/hebdx/8050.html/dx/sxdx/8049.html/dx/sxdx/8048.html/dx/sxdx/8047.html/dx/sxdx/8046.html/dx/sxdx/8045.html/dx/sxdx/8044.html/dx/bjdx/8043.html/dx/bjdx/8042.html/dx/xcdxyy/8041.html/dx/bjdx/8040.html/dx/xcdxyy/8039.html/dx/bjdx/8038.html/dx/bjdx/8037.html/dx/xcdxyy/8036.html/dx/xxdxyy/8035.html/dx/shdxyy/8034.html/dx/xxdxyy/8033.html/dx/xxdxyy/8032.html/dx/pdsdxyy/8031.html/dx/shdxyy/8030.html/dx/pdsdxyy/8029.html/dx/pdsdxyy/8028.html/dx/aydxyy/8027.html/dx/shdxyy/8026.html/dx/aydxyy/8025.html/dx/aydxyy/8024.html/dx/xgdxyy/8023.html/dx/lndxb/8022.html/dx/xgdxyy/8021.html/dx/lndxb/8020.html/dx/lndxb/8019.html/dx/xgdxyy/
