1、英语演讲稿关于美食【篇一：健康饮食英文演讲稿】 healthy diet there are many people who think that wealth is better than health. i used to think so until one day i read a story about howard hughes. he was an american billionaire who got anything he wanted. however, in the last twenty years of his life, his health began to d
2、eteriorate and he was miserable. he had the best doctors and nurses. however, he could still find no relief. i realized that health is worth all the money in the world. if you have millions of dollars but your health is poor, you will not be able to do what you want to do. so i would like to say don
3、t hurt yourself trying to make money instead of taking care of your body and be happy with what you do have. health is more important. so i think heath is very important. people can do nothing if they are always in poor health, let alone happiness. no matter we are rich or not, we can not ignore the
4、 importance of health. today，many people cant be in good health，so，how to keep healthy is very important. ill say something about food and health. more and more people are realizing the importance of good health. but how to keep fit? in my opinion, a healthy diet is very important for your health. d
5、o you know what a healthy diet is? firstly, you should have a balanced diet. you may not like eating vegetables. you think they are not so delicious. but vegetables have a lot of nutrition. they are very good for your health. secondly, youd better eat regular meals. you need to eat breakfast, lunch,
6、 and dinner every day. regular meals throughout the day give you enough energy to carry out your daily activities. never skip breakfast. it is the most important meal of the day. eat bigger meals earlier in the day. dont have a big dinner. thirdly, most of you like eating snacks. they may affect you
7、r appetite. besides, too many snacks make you fat. in a word, if you want to be healthy, you should keep a healthy diet. it is time for us to do something now, i think. that 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! l
8、ets do it instead of talking about it. thats all i want to say to you【篇二：英语演讲稿关于饮食】 i shall be speaking today about before we start our presentation, lets take a brief look at if you give a diet to laboratory animalits very common for animals to gain a good bit of weight when given access to this di
9、et. even if theyre given healthy food at the same time, theyll tend to ignore the healthy food and eat a diet like this. and there are two properties of this diet that help promote overeating and obesity in laboratory animals. what would you say the two features are?sugar and fat.sugar is what peopl
10、e usually guess first and thats correct, fat is number two, so you guys are good so far. who can guess what the third might be? salt is a good guess, but thats not the answer. but why would a lab animal seek out a diet, become very overweight, become nutritionally deficient in some things because it
11、s not eating the healthy foods to the extent that it becomes unhealthy? the fact is those lab animals have a hard-wired preference for foods that are high in fat and high in sugar, primarily because of the energy density that those foods bring to one, the seeking out fat and sugar is a highly evolve

15、esting. you hear a lot about saturated fat and unsaturated fat. as you know, unsaturated fat is healthy and you want to have this in your diet. trans fats have become a really interesting issue. there are groups of people who have studied the impact of trans fats on health for a number of years. the
16、y have found that trans fats were having a very negative impact on health.what are trans fats? theyre unsaturated fatty acids that get formed when foods are partially hydrogenated. when you see that partially hydrogenated oils on an ingredient list, that means theres trans fat. why would companies 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 commercially
