5、r 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 about before we start ou

6、r presentation, lets take a brief look at today were going to talk the two big ones that people are usually concerned with: carbohydrates and fat. lets start with carbohydrates. sugars, in other words.theyre used by the body for pretty immediate energy.there are three classes of sugar: monosaccharid

7、es, disaccharides, and polysaccharides. its not so important that you know which sugars fall under each of these categories, but it is important to know that there are different categories of sugars. under the monosaccharides, glucose, fructose and galactose are the sugars. disaccharides, where you

8、have several sugars paired together, are maltose, sucrose, and lactose.then the polysaccharides are the complex carbohydrates, and thats starch, glycogen, and cellulose. if you look at sources of these different carbohydrates, the glucose comes from fruit. thats not the only place but thats a primar

9、y source of it. you see the lactose of course from milk, and then you get down to the celluloseand starches,cereals and vegetables become the primary source of these. are we eating too much or too little of these different classes of sugars? well, as you might guess, we eat too much of the simple su

10、gars and the disaccharide sugars and we eat too little of the complex carbohydrates. so if you followed a diet where you ate less junk food and ate more fruits and vegetables, for example, just those two little rules you would help shift around this balance of sugars in a way that would benefit heal

11、th. theres sugar in a lot of foods where you dont expect it. for example: peanut butter. heres a list of ingredients from skippy peanut butter and you see that sugar is the second most common ingredient. heres another example. beef stew, you wouldnt necessarily expect to find sugar in beef stew but

12、its there. now its down the list of ingredients, its actually toward the end, but if you look at the marketing of this and look at the can it says, theres fresh potatoes and carrots, but actually theres more sugar in this than there is carrots. okay, lets talk about fat for a moment. fat has twice t

13、he calories per unit weight as protein and carbohydrate. so its 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 disc

14、ussion 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, thats protective against things like heart disease and y

15、ou 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 o

16、f 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? theyre unsaturated fatty acids that get formed when foods are partially hydrogenated. when you see that partially hydr

17、ogenated 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 appealing for the industry. it gives foods a longer shelf life. they tend

18、 to stay stable during deep frying and then the palatability goes up and the foods taste better.getting 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 health. you have the u

19、nsaturated 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, thats not good for you. and they lower hdl.the

20、 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 its important for the public health to change the portioning of fat so you move from bad to the bette

21、r 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 americanbillionaire who got anything he wanted. however, in the last twenty years of his life, his health

22、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

23、to say dont 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

24、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, a healthy diet is very important for your
