关于粮食的英语作文：饮食的改变
In the past five years there have been many changes in people’s diet.From the table listed above, we can find that people consume more milk and meat than they used to.On the other hand, they eat less grain, fruit and vegetables today than in the past.What has caused these changes? There are mainly two reasons.In the first place, with the development of economy people have more money.The price of meat and milk is much higher than that of grain;therefore, in the old days people couldn’t afford them.But now they have enough money to buy both meat and milk.In the second place, more and more people think that diet is very important to their health.As a result, they change their eating habits eating more nutritious food such as milk and meat.I think that milk and meat are important to one’s health.But if people eat too much rich food, some problems will be caused.In conclusion, people should keep a balance in their diet.Not only should they consume a lot of meat and milk but they should also eat enough grain, fruit and vegetables for the sake of their health.

People in different parts of our country have very different ideas about what is good to eat.In our country, for example, people from the south like to eat rice whereas people living in the north prefer bread or noodles.The natives of Hunan or Sichuan enjoy hot food while those of Shanghai or Suzhou will choose sweet dish.But even if people live in the same part of the country, their tastes vary greatly.Old people and young ones have different tastes;men and women also have their different preferences.In a restaurant, some customers order soups that is thick and heavy, while others drink soup that is thin and clear.A few people only eat vegetables.They de noteat fish or chicken.Therefore, it is not easy for restaurants to satisfy the needs of all the customers.To increase their business, the restaurants in the cities try their best to prepare foods of different kinds and

Eat For Convenience And Hobby
“Tell me what you eat, and I will tell you who you are.” Brillat-Savarin has showed his views of eating.And I’m totally agree to him, everything done by someone can be related to his/her personality, eating habits included.Eating is so interesting a thing that I would like to explore what the main eating habits of college students.To be honest, after my observation and personal experience , eating habits of college students can be summarized as two words: convenience and hobby.In the college, takeout menus are of great significance.As we all know, in addition to the classroom, most of students’ time is spent in the bedroom, for which they think it is too troublesome to go out for food for a special purpose.Then, takeout menus work because of it’s convenience.Though takeout above the menus have been tasted for many times, they enjoy the life that a ring call can bring a good dinner or supper.At the mention of takeout menus, the taste is also important, without doubt, to attract the students.So, elicit another keyword: hobby, that is to say the students like the tasty food above the menu.Mark Twin has said，“Part of the secret of success in life is to eat what you like and let the food fight it out inside.” It is quite fun , but eating the food that you like is indeed a blessed thing.In that way, they have
something to say,“The food in the canteen is not fit to my taste, I do not like that.”So, they just pick what their favorite to enjoy.Food stalls and sellers have great business as a result.College students’ eating habits are not very satisfactory, they do not have regular eating habits as well except those two problems above.I just feel like calling attention to those students who has bad eating habits, “One can not think well, love well, sleep well if one has not dined well.”
Wish all of us good eating habits!
第四篇：英语演讲稿关于饮食[范文模版]
I shall be speaking today about
Before we start our presentation, let's take a brief look at
If 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 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, and that’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 you look 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 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 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.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.
第五篇：《科技改变生活》英语作文
Science and technology change our life With the rapid development of science and technology, our daily life has been changed a lot.New technological inventions begin to play an essential role, for example, the robot can help us clean up and finish much homework.As a result of that, we can spare more time to be dedicated to our job, and we are able to be fully exposed to our hobbies.Always have some time to hope that their cell phone is “Hello, you dial the number temporarily unable to connect” state.So, we all need a jacket that can mask the mobile phone signal.Dancepants sports music is designed to be two Lithuania designers.The clothes made of this fiber can be used to convert the temperature of the human body into electrical energy, which can be driven by electronic devices such as MP3 players.Respite of that, some disadvantages of technological inventions may appear.The excessive use of high technology can also make our life be passive.The majorities of us will become lazier men, and they are unwilling to explore minds any longer.All in all, the improvement of science and technology can smoothly increase the standards of people's life.On the other hand, it may lead to the laziness of people's behavior and mind.
