听力原文： When people have enough B vitamins, their appetite is good and their nerves are calm. B vitamins in the diet come from some meats and vegetables, milk, cottage cheese, and whole grains.
When a grain is processed, it loses vitamins. For example, there is a big difference between white and brown rice. When rice is processed, the brown outside is lost. The brown outside of rice has an important B vitamin which white rice lacks. In short, brown rice has more B vitamins than processed rice.
Vitamin C keeps the cells of the body together. It helps skin tissue recover from cuts and bums. Vitamin C in the diet comes from tomatoes, fruits like lemons and oranges, and some vegetables such as cabbage and green peppers.
Vitamin D is called the "sunshine" vitamin. When people sit outside, ultraviolet rays from the sun change fat in their skin to vita- min D. Vitamin D disease in children are called rickets. Rickets is more common in countries that have long winters with little sun- shine.

A．How to keep fit.
B．Common diseases caused by vitamins.
C．Vitamins and our health.
D．Vitamin in different kinds of vegetables.

A Guide to Eating for Sports
There is a piece of good news that eating to reach your peak performance level likely doesn't require a special diet or supplements. It's all about working the right foods into your fitness plan in the right amounts. Here are some basics.
Eat Extra for Excellence
Teen athletes have unique nutrition needs. Because athletes work out more than their less-active peers, they generally need extra calories to fuel both their sports performance and their growth. Depending on how active they are, teen athletes may need anywhere from 2,000 to 5,000 total calories per day to meet their energy needs.
Since tech athletes need extra fuel, it's usually a bad idea for them to diet. Athletes in sports where weight is emphasized—such as wrestling, swimming, dance, or gymnastics—may feel pressure to lose weight, but they need to weigh that choice with the possible negative side effects mentioned above. If a coach, gym teacher, or teammate says that you need to go on a diet, talk to your doctor first or visit a dietitian who specializes in teen athletes. If a health professional you trust agrees that it's safe to diet, he or she can work with you to develop a plan that allows you to perform. your best and lose weight.
Eat a Variety of Foods
You may have heard about "carb loading" before a game. But when it comes to powering your game fox' the long haul, it's a bad idea to focus on only one type of food. Carbohydrates are an important source of fuel, but they're only one of many foods an athlete needs. It also takes vitamins, minerals, protein, and fats to stay in peak playing shape.
Muscular Minerals and Vital Vitamins
Calcium helps build the strong bones that athletes depend on, and iron carries oxygen to muscles. Most teens don't get enough of these minerals, and that's especially tree of teen athletes because their needs may be even higher than those of other teens.
To get the iron you need, cat lean red meats (meats with not much fat on them); grains that are fortified with iron; and green, leafy vegetables. Calcium—a must for protecting against stress fractures— is found in dairy foods, such as low-fat milk, yogurt, and cheese.
In addition to calcium and iron, you need a whole bunch of other vitamins and minerals that do everything from help you access energy to keep you from getting sick. Eating a balanced diet, including lots of different fruits and veggies, should provide the vitamins and minerals needed for good health and sports performance.
Protein Power
Athletes need slightly more protein than less-active teens, but most teen athletes get plenty of protein through regular eating. It's a myth that athletes need a huge daily intake of protein to build large, strong muscles. Muscle growth comes from regular training and hard work—not popping a pill. And taking in too much protein can actually harm the body, causing dehydration, calcium loss, and even kidney problems.
Good sources of protein are fish, lean meats and poultry, eggs, dairy, nuts, soy, and peanut butter.
Carb Charge
Carbohydrates provide athletes with an excellent source of fuel. Cutting back on carbs or following low-carb diets isn't a good idea for athletes because restricting carbohydrates can cause a person to feel tired and worn out, which ultimately affects performance.
Fat Fuel
Everyone needs a certain amount of fat each day, and this is particularly true for athletes. That's because active muscles quickly bum through carbs and need fats for long-lasting energy. Like carbs, not all fats are created equal. Experts advise athletes to concentrate on healthier fats, such as the unsaturated fat found in most vegetable oils. Choosing when to cat fats is also important for athletes. Fatty

Carbohydrates are found in foods such as bread, potatoes and sugar. They are excel- lent energy producers, but if eaten too excess may be largely converted to fat and a reduction in the amount of carbohydrates or "starchy' foods is one of the obvious ways to reduce weight, since most of us eat too much of them anyway. Protein, found in meat and cheese, is used for tissue building and in the developed countries most people eat about ll0g daily, which is a good deal more than the recommended minimum of 70g a day. In underdeveloped countries where food is scarce and periodical famine may occur, children in particular suffer from protein deficiency, since this is the material most need- ed for growth. Animal fats, e. g. butter, are also good sources of energy, but are some- times held to cause increased cholesterol levels in the blood (which may lead to fatty de- posits in the arteries) and are therefore best avoided by people suffering from certain forms of heart disease, vegetable fats being recommended as a substitute.
Vitamins are another essential requirement for health. There are about forty known vitamins, but the most generally referred to are A, B, C, D and E. Deficiency of Vita- min A, found in carrots, liver, etc., is alleged to affect the vision and the skin and re- duce resistance to infection. Vitamin C, present in nearly all fruit, particularly oranges and other citrus fruit, has come to be regarded as particularly effective in the prevention of colds and low energy states and claims have recently been put forward regarding the efficacy of large doses of Vitamin C in the treatment of certain mental illnesses.
Among the minerals we need, the most important are calcium, iron and iodine. Milk is one of the richest sources of calcium, which helps to build our bones and our teeth. Lack of iron in the blood produces anaemia and children and others suffering from anaemic conditions are generally advised to increase their intake of iron, which may be found in liver, molasses and dates among other foods.
In any diet, natural foods are best. In the Western world, at least, we have become increasingly dependent on "convenience foods": frozen peas, tinned meat and fish, ready-to-eat meals from the supermarket, anything which is quick to prepare, looks more or less appetising and satisfies our immediate hunger. We have ceased to care that most of what we eat has had the goodness processed out of it. We rely on pills to supply what our food lacks. We ignore the preservatives, artificial coloring and additives in the packaged foods we buy. In the kind of world we live in, however, there is, of course, no quick, easy answer.
Climate and work play an important part in diet. People in hot climates require fewer carbohydrates than those in colder regions, and those engaged in heavy manual labor or physical exertion, such as dockers or athletes, require more protein to keep them fit for their work. We are all individuals and a balanced diet must take into account genetics, environment, employment and, last but not least, emotional stress. Te
