They’re unsaturated fatty acids that get formed when foods are partially you see that partially hydrogenated oils on an ingredient list, that means there’s trans would panies do this? Why would the food industry want to introduce trans fat in the first place? Well, it changes the food in ways that are mercially appealing for the gives foods a longer shelf tend to stay stable during deep frying and then the palatability goes up and the foods taste back to the concept that there are good and bad fats, if we look at the left hand side here, is a table or a graphic showing the fats that tend to have beneficial impacts on have the unsaturated seafood, olive oils and some nuts are high in the unsaturated these kinds of rats are not necessarily bad fats look like this, and those are the saturated fats and the trans bad fats raise the LDL levels, that’s not good for they lower trans fats that we mentioned before that you can see listed over here from margarine, shortenings, deep fried foods, a lot of fast foods and baked goods have a negative impact on health as it’s important for the public health to change the portioning of fat so you move from bad to the better fats in the diets.第二篇：健康飲食的英語演講稿healthy diet there are many people who think that wealth is better than used to think so until one day i read a story about howard was an american billionaire who got anything he , in the last twenty years of his life, his health began to deteriorate and he was had the best doctors and , he could still find no realized that health is worth all the money in the you have millions of dollars but your health is poor, you will not be able to do what you want to i would like to say don’t hurt yourself trying to make money instead of taking care of your body and be happy with what you do is more i think heath is very can do nothing if they are always in poor health, let alone matter we are rich or not, we can not ignore the importance of ，many people cant be in good health，so，how to keep healthy is very say something about food and and more people are realizing the importance of good how to keep fit? in my opinion, a healthy diet is very important for your you know what a healthy diet is? firstly, you should have a balanced may not like eating think they are not so vegetables have a lot of are very good for your , you’d better eat regular need to eat breakfast, lunch, and dinner every meals throughout the day give you enough energy to carry out your daily skip is the most important meal of the bigger meals earlier in the have a big , most of you like eating may affect your , too many snacks make you a word, if you want to be healthy, you should keep a healthy is time for us to do something now, i is, we should eat the right kinds of food, and do not eat any of the unhealthy food!let us do it right away to keep health!lets do it instead of talking about all i want to say to you篇二：關(guān)于健康的英語演講稿文章編制 扣扣：一**一六五三九八二 how to stay healthy as we all know, healthy is very important to do you really know how to stay healthy? here are some useful , we should do exercise if we have example, we can go to swim in the summer we can take a walk after exercise makes us healthy and , we should take more vegetables and fruit and less eating junk food and drinking but not least, we should go to bed early and wake up should have enough sleep, or we will get sleepy in the day we pay more attention to the tips above, we will have healthier wish everybody has a strong and healthy ,健康對每個人來說都很重要。第二,我們應該吃更多的蔬菜和水果,少吃糖果。我們都知道小學時期是生長發(fā)育的關(guān)鍵階段，可是很多同學都有挑食、偏食、貪食的壞習慣。有的同學把肉吃完，就結(jié)束了用餐；有的同學只吃蔬菜。那么這時，我們可以選擇從自己家里帶一些面包或者餅干來食用。近幾年來，三鹿“毒奶粉”事件剛剛平息，“蘇丹紅”、“病蟲桔”事件又被揭穿，“瘦肉精”、“毒豆芽”一波又一波輪番上演?！笆场彼坪跏且患焚M苦心的事。在營養(yǎng)合理的情況下，不能忽視衛(wèi)生，無論是食物原料的挑揀、洗滌、切配、加工烹飪、裝盤，都要嚴格。渭南高級中學于20xx年8月建成招生，是我市唯一的一所市教育局直屬學校，20xx年經(jīng)省教育廳評估被命名為陜西省示范高中。一直以來，我們堅持把安全管理特別是餐飲衛(wèi)生安全管理作為頭等大事，列為“一把手”工程來抓，學校專門成立了由黨?？ｉL親自掛帥，由主管副校長、總務主任、校辦主任參加的學校餐廳衛(wèi)生安全工作領導小組。三、加強正面引導，規(guī)范人員管理我們堅持員工上崗前必須進行崗前培訓，學習相關(guān)的法律、法規(guī)和學校餐廳管理的各項規(guī)章制度，提高法律意識和食品衛(wèi)生安全意識。二是儲存關(guān)。同時，為了防止人為投毒、病菌傳播及交叉感染，我們在加工場所入口處安裝了警示標志，禁止未穿戴工裝及無關(guān)人員不得進入加工儲藏場所。餐廳的水池專池專用，分別設有洗菜池、浸泡池和拖把池，并有明顯標識。做到了藥品采購有票據(jù)，消殺有記錄。一個到位：就是管理工作到位。二是切實做好廚房衛(wèi)生防疫工作。儲存關(guān)：所有食品均要分類上架儲存；肉食及需要保鮮的要進冷柜儲存；所有食品都要留樣48小時以上。三是加強采購管理。長身體的時候是我們發(fā)展的必然，我們必須要為自己的健康做更多的準備，也需要重視起來，很多時候我們飲食并不規(guī)律，有時候會嫌棄食物的口感不好，有時候是想要吃自己喜歡吃的食物，因此在營養(yǎng)攝入方面并不齊全，造成自己出現(xiàn)了很多問題，比如健康問題，高矮胖瘦等等都與飲食有關(guān)。我們學習每天都需要消耗能量，我們成長也要消耗能量，但是能量是均等等，如果攝入的能量不能及時消化就會變成脂肪，攝入的能量過少，就會消耗我們身體的脂肪，消耗我們的健康，就會讓我們變得干瘦，這樣不管哪種，都會讓我們變得更加弱小容易生病，也容易感冒。同學們，
