英语演讲稿美食篇一：健康饮食英文演讲稿Healthy DietThere 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 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 can't be in good health，So，how to keep healthy is very important. I'll 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. Don't 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 usdo it right away to keep health! Let's do it instead of talking about it. That's all I want to say to you 篇二：各国美食英语演讲C When we talk about food,there are really so many kinds.If we introduce every kind of them,I don't think it can be over in this class even in this year.Y So we will just introduce some typical and popular food in this PPT.C French food’s feature is wide choice of material.A sandwich might not sound like typical, but it's certainly worthy of your consideration.It's always a yummy lunchtime meal!YCroissant[kr??sant] is also a typical famous French food .C The macaron is commonly filled with butter-cream or jam filling sandwiched between two cookies.YFrench crepes are usually of two types: sweet and salty.C Then is Japanese.Noodles are an important part of Japanese food.Y Soba noodles are native.They can be served cold or hot and with various toppings.They also eat rice.C Hundreds of different fish, shellfish and other seafood from the oceans and rivers are used in the Japanese food.

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’snot 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 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.Let’s start with carbohydrates. Sugars, in other words.They’re used by the body for pretty immediate energy.There are three classes of sugar: monosaccharides, disaccharides, and polysaccharides. It’s 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 have several sugars paired together,are maltose, sucrose, and lactose.Then the polysaccharides are the complex carbohydrates, andthat’s starch, glycogen, and cellulose. If you look at sources of these different carbohydrates, the glucose comes from fruit. That’s not the only place but that’s a primary 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 sugars 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 health. There’s sugar in a lot of foods where you don’t expect it. For example: peanut butter. Here’s a list of ingredients from skippy peanut butter and you see that sugar is the second most common ingredient. Here’s another example. Beef stew, you wouldn’t necessarily expect to find sugar in beef stew but it’s there. Now it’s down the list of ingredients, it’s actually toward the end, but if youlook at the marketing of this and look at the can it says, there’s fresh potatoes and carrots, but actually there’s more sugar in this than there is carrots.Okay, let’s talk about fat for a moment. Fat has twice the calories per unit weight as 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 havestudied 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 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 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 for you. And they lower HDL.Thetrans 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.。
