Canned Foods: Convenience and Nutrition

Meeting your family's nutritional needs may seem difficult considering today's busy lifestyles. But it doesn't have to(51). Even a new emphasis(52)more fruits and vegetables doesn't necessarily mean more preparation time if you take(53) of the convenience of canned foods.

When you open a(54)of fruit or vegetable at home you have at hand fresh-packed nutritional produce, with no man-made ingredients, no preservatives. And all the work has been done for you: the slicing, the peeling, even the cooking. Canned fruits and vegetables leave you the(55) to be creative. And with the variety of fruits and vegetables available these days, you can serve different combinations, create new dishes, and(56) new tastes to old recipes. Canned foods are good as well. A United States Department of Agriculture and National Food Association co-sponsored study shows canned vegetables to be just as(57) as fresh or frozen. Because canned vegetables are processed within hours of(58)packed, they generally retain 70 to 90(59)of their nutrients.

Fruit and vegetable canning is as simple(60)when your grandmother "put up" tomatoes and other things from the garden. Fresh produce is taken from the field at just the right time, delivered to the cannery, checked, washed, sealed, and sterilized. All this generally happens in less(61) 24 hours to(62) the best quality and nutritional value without the need for any preservatives.

Use the liquids that vegetables are canned(63)as a substitute(64) water in recipes to get that last drop of good nutrition.

Most major brands of canned fruits and vegetables include nutritional content and ingredient statements on their(65). This is especially important to those on calories-conscious or restricted diets.

听力原文： Health food is a general term applied to all kinds of food that are considered more healthful than the types of foods widely sold in supermarkets. For instance, whole grains, fried beaus, and corn oil are health foods. A narrower classification of health food is natural food, which is used to distinguish between types of the same food. Raw honey is a natural sweetener, whereas relined sugar is not. Fresh fruit is a natural food, but canned fruit, with sugars and other additives, is not. The most precise term of all and the narrowest classification within health food is organic food, which is used to describe food that has been grown on a particular kind of farm. Fruits and vegetables that are grown in gardens that are only treated with organic fertilizers, that are not sprayed with poisonous insecticides, and that are not refined after harvest, are organic foods. Meats, fish, dairy and poultry products from animals that are fed only organically-grown feed and that are not injected with hormones are organic foods.

In choosing the type of food you eat, then, you have basically two choices: inorganic, processed foods, or organic, unprocessed foods. A wise decision should include investigation of the claims that processed foods contain chemicals, some of which ate proven to be poisonous, and that vitamin content is greatly reduced in processed foods.

(30)

A．Refined food.

B．Processed food.

C．Natural food.

D．Organic food.

Food which is kept too long decays because it is attacked by yeasts（酵母菌)，moulds （霉) an

Food which is kept too long decays because it is attacked by yeasts(酵母菌)，moulds (霉) and bacteria(细菌). The canning process, however, seals the product in a container so that no infection can reach it, and then it is sterilized(消毒)by heat. Heat sterilization destroys all infections present in food inside the can. No chemical preservatives are necessary, and properly canned food does not deteriorate during storage.

Today vegetables, fish, fruit, meat and beer are canned in enormous quantities. Foods that were previously seasonal may now be eaten at any time, and strange foods are available far from the countries where they are grown. The profitable crops many farmers now produce often depend on the proximity of a canning factory.

The first stage in the canning process is the preparation of the raw food. Diseased and waste portions are thrown away; meat and fish are cleaned and trimmed; fruit and vegetables washed and graded for size. The jobs are principally done by machine.

The next stage, for vegetables only, is blanching. This is immersion(浸洗) in very hot or boiling water for a short time to remove air and soften the vegetable. This makes it easier to pack into cans for sterilization. Some packing machines fill up to 400 cans a minute. Fruit, fish and meat are packed raw and cold into cans, and then all the air is removed. When the cans are sealed, the pressure inside each can is only about half the pressure of the outside air. This is" vacuum" packing.

During the sterilization process which follows, the cans are subjected to steam or boiling water, with the temperature and duration varying according to the type of food. Cans of fruit, for example, take only 5-10 minutes in boiling water, while meat and fish are cooked at higher temperature for longer periods . After sterilization, the cans are cooled quickly to 32℃, to prevent the contents from becoming too soft.

The final stage before dispatch to the wholesale or retail grocer is labeling, and packing the tins into boxes. Nowadays, however, labeling is often printed on in advance by the can maker and no paper labels are then required.

The word" deteriorate" can be replaced by ______.

A．become soft

B．go bad

C．change taste

D．turn hard

Eight Tips for Eating WellA healthy balanced diet contains a variety of typos of food, inc

Eight Tips for Eating Well

A healthy balanced diet contains a variety of typos of food, including lots of fruit, vegetables and starchy (淀粉类) foods such as wholemeal bread and wholegrain cereals; some protein-rich foods such as meat, fish, eggs and lentils; and some dairy foods.

1. Base your meals on starchy foods

Starchy foods such as bread, cereals, rice, pasta and potatoes are a really important part of a healthy diet. Try to choose wholegrain varieties of starchy foods whenever you can.

Starchy foods should make up about a third of the food we eat. They are a good source of energy and the main source of a range of nutrients in our diet. As well as starch, these foods contain fiber, calcium, iron and B vitamins.

Most of us should eat more starchy foods —try to include at least one starchy food with each of your main meals. So you could start the day with a wholegrain breakfast cereal, have a sandwich for lunch, and potatoes, pasta or rice with your evening meal.

Wholegrain foods contain more fiber and other nutrients than white or refined starchy foods. We also digest wholegrain foods more slowly so they can help make us feel full for longer.

2. Eat lots of fruit and vegetable

Most people know we should be eating more fruit and vegetable. But most of us still aren't eating enough.

Try to eat at least 5 portions of a variety of fruit and vegetable every day. It might be easier than you think. Try adding up your portions during the meals throughout the day. You can choose from fresh, frozen, tinned, dried or juiced, but remember potatoes count as a starchy food, not as portions of fruit and vegetable.

3. Eat more fish

Most of us should be eating more fish —including a portion of oily fish each week. It's an excellent source of protein and contains many vitamins and minerals.

Aim for at least two portions of fish a week, including a portion of oily fish. You can choose from fresh, frozen or canned —but remember that canned and smoked fish can be high in salt.

What are oily fish？

Some fish are called oily fish because they are rich in certain types of fats, called omega 3 fatty acids, which can help keep our hearts healthy.

How much oily fish？

Although most of us should be eating more oily fish, women who might have a baby one day should have a maximum of 2 portions of oily fish a week (a portion is about 140g). And 4 is the recommended maximum number of portions for other adults.

Anyone who regularly eats a lot of fish should try and choose as wide a variety as possible.

4. Cut down on saturated (饱和的) fat and sugar

Fats

To stay healthy we need some fat in our diets. What is important is the kind of fat we are eating. There are two main types of fat:

- saturated fat —having too much can increase the amount of cholesterol (胆固醇) in the blood, which increases the chance of developing heart disease

- unsaturated fat—having unsaturated fat instead of saturated fat lowers blood cholesterol

Try to cut down on food that is high in saturated fat and have foods that are rich in unsaturated fat instead, such as vegetable oils, oily fish, avocados, nuts and seeds.

Foods high in saturated fat are: meat pies, sausages, meat with visible white fat, hard cheese, butter and lard, pastry, cakes and biscuits, cream, soured cream and creme fraiche, coconut oil, coconut cream or palm oil.

For a healthy choice, use just a small amount of vegetable oil or a reduced-fat spread instead of butter, lard or ghee. And when you are having meat, try to choose lean cuts and cut off any visible fat.

Sugar

Most people are eating too much sugar. We should all be

A．Y

B．N

C．NG

Heat sterilization destroys all infectious present in food inside the can. No chemical preservatives are necessary, and properly canned food does not deteriorate during storage.

Food deteriorates during storage because ______.

A．necessary chemical preservatives are totally absent from it

B．it is infected with yeasts, moulds and bacteria

C．heat sterilization destroys infections present in it

D．it isn't fit for storage

All of us eat everyday, but most of us don't understand nutrition (营养). We often make mistakes in talking about good diet.

For example, many people think that food, such as rice, bread and potatoes, will make one grow fat. In fact, those food are very good to one's health. They are good sources of many vitamins (维他命). And in comparison with steak and beef, they contain less amount of calories.

Some people don't like canned or frozen vegetables, because they think fresh vegetables cooked at home are always better. This is again wrong. In fact, whether the vegetables are good or not depends more on how they are prepared. Overcooking, for example, destroys many good qualities of vegetables. Vegetables cooked in too much water can lose a large amount of vitamins.

It is widely believed that extra vitamins provide more energy. But taking more than the body needs doesn't make it function better.

It is also wrong to say that vegetables grown in poor, worn-out soil are lower in vitamins than vegetables grown in rich soil. The vitamins in our foods are in the plants themselves. They don't come from the soil. However the minerals in a plant depend on the minerals in the soil.

In short, there are many false ideas about nutrition. We need to correct them.

This passage is mainly about ______.

A．nutrition

B．vitamins

C．vegetables

D．health

第10题

What makes Americans spend nearly half their food dollars on meals away from home？ The ans

wers lie in the way Americans live today. During the first few decades of the twentieth century, canned and other convenience foods freed the family cook from full-time duty at the kitchen range.

Then, in the 1940s, work in the wartime defense plants took more women out of the home than ever before, setting the pattern of the working wife and mother. Unless family members pitch in with food preparation, women are not fully liberated from that chore.

It's easier to pick up a bucket of fried chicken on the way home from work or take the family out for pizzas or burgers than to start opening cans or heating up frozen dinners after a long, hard day. Also nowadays, the rising divorce rate means that there are more single working parents with children to feed. And many young adults and elderly people, as well as unmarried and divorced mature people, live alone rather than as a part of a family unit and don't want to bother cooking for one. Fast food is appealing because it is fast, it doesn't require tiny dressing up, it offers a "fun" break in the daily routine, and the outlay of money seems small. It can be eaten in the car--sometimes picked up at a drive-in window without even getting out--or on the nm. Even if it is brought home to eat, there will never be any dirty dishes to wash because of the handy disposable wrappings. Children, especially, love fast food because it's finger food, no struggling With knives and forks, no annoying instructions from adults about table manners.

Americans enjoy fast food mainly because ______.

A．it can be eaten in the car

B．it is much more tasty than home-made food

C．one only uses his fingers while eating it

D．it is time-saving and convenient
