americanbillionaire who got anything he wanted. however, in the last twenty years of his life, his health began to deteriorate 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’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 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, ahealthy diet is very important for your health. do 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, you’d better eat regular meals.you need to eat breakfast, lunch, 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 your 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! lets 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 aboutbefore we start our presentation, lets take a brief look atif you give a diet to laboratory animalit’s very common for animals to gain a good bit of weight when given access to this diet. even if they’re given healthy food at the same time, they’ll 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 people usually guess first and that’s 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 that’s not the answer. but why would a lab animal seek out a diet, become very overweight, become nutritionally deficient in some things because it’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 arehigh 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 evolved, adaptive evolutionary trait of animals and human.today we’re going to talk the two big ones that people are usually concerned with: carbohydrates and fat.okay, let’s talk about fat for a moment. fat has twice the calories per unit weight a s protein and carbohydrate. so it’s a very efficient way of securing energy. but if one is not deprived of calories,then having fat my not be so helpful. there are different kinds of fat that have different impacts on health. several concepts that are relevant in the discussion of fat: cholesterol, saturation, and trans fat. first of all,cholesterol.there are different kinds of cholesterol, hdl and ldl. it was a major discovery when scientists in the last century found that hdl is good and ldl is bad, the hdl, that’s protective against things like heart disease and you want to have a higher level of that and a lower level of hdl.the saturation is interesting. 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. they have found that trans fats were having a very negative impact on health.what are trans fats? they’re unsaturated fatty acids that get formed when foods are partially hydrogenated. when you see that partially hydrogenated oils on an ingredient list, that means there’s 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 appealing for the industry. it gives foods a longer shelf life. they tend to stay stable during deep frying and then the palatability goes up and the foods taste better.getting backto 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 health. you have the unsaturated fat. the seafood, olive oils and some nuts are high in the unsaturated fats. so these kinds of rats are not necessarily bad. the bad fats look like this, and those are the saturated fats and the trans fat. these bad fats raise the ldl levels, that’s not good fo r you. and they lower hdl.the 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 well. so 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.【篇三：关于食物的英语演讲稿】healthy diet there are many people who think that wealth is better than health. i used tothink so until one day i read a story about howard hughes. he was an

shall be speaking today aboutbefore we start our presentation, lets take a brief look at today we’re going to talk the two big ones that people are usually concernedwith: carbohydrates and fat. okay, let’s talk about fat for a moment. fat has twice the calories per unitweight as protein and carbohydrate. so it’s a very efficient way of securing energy.but if one is not deprived of calories, good morning, my dear teachers and my friends.it is my great pleasure to stand here to have a speech, today i am going to talkabout”food safety”.〈mention the food safety, peoples hearts are unusual interest, concern. becausewith economic and social progress, economic globalization continues, people foodculture diversity, food hygiene and safety1.changing how we farm2.changing what we eateating less meat can reduce the demand for mined phosphate. this is becausevegetable-based production is more efficient in its use of phosphorus then livestock production. although different types of meat havedifferent levels of mined phosphate demand depending on the farming system used toproduce them. meat from livestock grazed on grassland that has not been fertilisedwith artificial fertilisers, will perform much better than meat from livestock grazed on fields that have been,or livestock fed on grain grown using artificial fertilizers3,changing how we deal with human exretasystems in favour of ecological sanitation. the report also calls for a changeto eu organic regulations to allow the use of human sewage –rich in ‘natural’phosphate - on agricultural land to ensure phosphate levels are maintained. globallyonly 10% of human waste is returned to agricultural soils. urine alone contains morethan 50% of the phosphorus excreted by humans. let the good faith in our hearts, and the let the world fill with love thankyou for your listening.篇四：英语演讲稿(食品安全) food safety a miracle - we are still alive leather milk, substandard milk powder, illegal cooking oil exposed in recentyears. it’s greatly influence our live. there are a couple of driving forces, i would argue, behind this undesirable tide.first, in the course of the rapid economic evolution, we ignore moral education,giving rise to the rising rate of the problem. more importantly, the lack of adequateregulation and punishment on those illegal producers enforces the trend. in fact, the poisonous food associated with japan. in china, a variety ofpesticides, antibiotics, antibiotics are from japan. in a manner of speaking, theproblem of chinese food should be attributed to japan. our country also make a list of healthy food additives and some law about it.however, many food manufacturers do not obey it and use lots of illegal foodadditives .these food additives are harmful to our body .for example, sanlu milkpowder is added in illegal chemicals. if babies eat it, they will get gallstone disease.another hot button is illegal cooking oil. many restaurants use the illegal cookingoil to reduce the cost so they can get more profits .however, the illegal cookingoil contains a large of chemicals that will cause cancer .so it is very terrible.to gain more money at the expense of consumers’ health. second, the overuse ofagricultural pesticide has resulted in the degradation of food quality. the excessivepesticide bears enormous health hazard for people. furthermore, some food producersinject hormones into domestic animals so as to make them grow more quickly and thusthey can turn in more profit. as a result, people’s health has been seriously disturbed.though many other countries, even countries like the u.s. and japan, have alsoexperienced food safety crises in some periods of their development, maybe none ofthem has witnessed food safety problems on such a large scale and during such a longperiod of time. actually, problematic food products had been with us for quite a longtime before we realized them and almost no single food or even drink can be claimedabsolutely safe. flours may contain too much chemicals like brightener that can turnthem into the desirable color; meat might have been produced by animals that haveconsumed chemicals to add to the red part of meat; vegetables may have too muchremnants of pesticides on their leaves; even milk and other beverages may have inthem poisonous chemicals to make them smell flagrant and tasty. there is no denying the fact that food safety is a grave problem with which thiscountry is confronted. a joke goes that everyone who can survive in china cansurvive in any other part of the world, which means that the test one faces inchina in terms of food safety is the gravest in the world. the most notable instancemight be the notorious san lu milk powder scandal which has drawn considerablepublicity in the past months. causing kidney stones among thousands of infants anddeaths of some of them, the milk powder containing overdose melamine is but one exampleof numerous substandard food products in this country. while blaming those wrongdoersand sympathizing those victims, we must examine the fundamental causes of the problemand work out effective solutions. factories or markets to check their performance. we only need to go and have alook at those restaurants to know that those bureaus are not working. i believe thatevery one of us has noticed that tableware is not properly sanitized in somerestaurants but no one says or does anything about that phenomenon. we needn’t go far to see the disastrous consequences of the food safety crisis.not only are people’s health and lives directly threatened, but tremendous amountsof resources are wasted. the thousands of tons of milk powder burned to ashes is acase in point. furthermore, an atmosphere of dishonesty and disbelief will permeatethe entire society, which will not only hinder the development of economy but willruin the nation spiritually.食物搭配与健康——材料一班赵存波各位老师，各位同学，大家上午好！我带来的演讲题目是《食物搭配与健康》。
