The importance of particular metals in the human diet has been realised wit

19、hin the past few decades, and the idea that geology might be related to health has been recognized for a number of elements such as iodine, zinc and selenium. For example, soils with low iodine contents produce crops and animals deficient in iodine. A lack of iodine in the human diet leads to some s

20、erious diseases.2. The ultimate source of metals within the human body is rocks, which weather into soil, gaining or losing some of their chemical constituents. The crops we eat selectively remove from the soil the elements that they require for growth. The water we drink contains trace elements lea

21、ched from rock and soil. Thus the geology and geochemistry of the environment have effects on the chemistry and health of plants, animals and people.3. So far there is no data to suggest that people living on metal-rich soils experience a potential health hazard. The levels of metals within naturall

22、y contaminated soils are generally not high enough to cause serious health problems. Living on metal-rich soils does not represent a health risk unless large quantities of soil are digested or metal-rich dust is inhaled. However, small children are particularly exposed to metal-rich dust topsoil in

23、playgrounds and gardens. They are also the most likely ones to eat potentially dangerous metal-rich soil.4. Heavy metals are persistent: they do not break down to other chemicals in the environment. Industrially polluted sites usually undergo intensive clean-up and rehabilitation because heavy metal

24、s are a health concern once they enter the food chain. Some trace metals are alleged to cause cancer and are also known to cause poisoning.5. In contrast naturally contaminated soils have not been subject to risk assessment studies and rehabilitation measures, despite the fact that they frequently p

25、ossess metal concentrations well above those of such polluted by humans and above environmental quality criteria.6. There is a vital need to understand the potential risks and long-term health effects of living on naturally contaminated soils. Future environmental investigations of naturally pollute

26、d soils should concentrate on the potential pathways of metals into the food chain and human body. Geologists should be part of such studies as they can provide the essential background information on rock and soil chemistry as well as the chemical forms of heavy metal pollution.（分数：8.00）(1).Paragra

It can have a dramatic effect on your bodys ability to fight off heart disease, cancer, diabetes, high blood pressure, stroke, and weak bones. With remarkable consistency, recent research has found that a diet high

30、 in plant-based foodsfruits, vegetables, dried peas and beans, grains, and starchy staples such as potatoesis the bodys best weapon in Uthwarting/U many health-related problems. These foods work against so many diseases that the same healthy ingredients you might use to protect your heart or ward of

31、f cancer will also benefit your intestinal tract and bones.Scientists have recently estimated that approximately 30 to 40 percent of all cancers could be avoided if people ate more fruits, vegetables, and plant-based foods and minimized high-fat, high-calorie edibles that have scant nutritional valu

32、e. Up to 70 percent of cancers might be eliminated if people also stopped smoking, exercised regularly, and controlled their weight. In the past, researchers had linked fat consumption with the development of cancers, but they currently believe that eating fruits, vegetables, and grains may be more

33、important in preventing the disease than not eating fat. “The evidence about a high-fat diet and cancer seemed a lot stronger several years ago than it does now,” says Melanie Polk, a registered dietitian and director of nutrition education at the American Institute for Cancer Research.The road to s

34、trong bones is paved with calcium-rich food. Leafy green vegetables and low-fat dairy products are excellent sources of calcium, the mineral that puts stiffness into your skeletal system and keeps your bones from turning rubbery and fragile. Your body uses calcium for more than keeping your bones st

35、rong. Calcium permits cells to divide, regulates muscle contraction and relaxation, and plays an important role in the movement of protein and nutrients inside cells. If you dont absorb enough from what you eat to satisfy these requirements, your body will take it from your bones. Because your body

36、doesnt produce this essential mineral, you must continually replenish the supply. Even though the recommended daily amount is 1,200 mg, most adults dont eat more than 500 mg. One reason may have been the perception that calcium-rich dairy products were also loaded with calories. “In the past, women,

37、 in particular, worried that dairy products were high in calories,” says Letha Y. Griffin, M. D., of Peachtree Orthopaedics in Atlanta. “But today you can get calcium without eating any high-fat or high-calorie foods by choosing skim milk or low-fat yogurt.” Also, low fat dairy products contain phos

38、phorous and magnesium and are generally fortified with vitamin D, all of which help your body absorb and use calcium. If you find it difficult to include enough calcium in your diet, ask your doctor about supplements. Theyre a potent way to get calcium as well as vitamin D and other minerals. But if

39、 you rely on pills instead of a calcium-rich diet, you wont benefit from the other nutrients that food provides. Getting the recommended vitamin D may be easy, since your body makes the vitamin when your skin is exposed to the suns rays.（分数：15.00）(1).Which kind of food is recommended to prevent hear

When someone has deeply hurt you, it can be

44、 extremely difficult to let go of your Ugrudge./U But forgiveness is possibleand it can be surprisingly beneficial to your physical and mental health. “People who forgive show less depression, anger and stress and more hopefulness,” says Frederic Luskin, Ph. D., author of Forgive for Good (Harper Co

45、llins, 2002). “So it can help save on the wear and tear on our organs, reduce the wearing out of the immune system and allow people to feel more vital.”So how do you start the healing? Try following these steps: Calm yourself. To defuse your anger, try a simple stress-management technique. “Take a c

46、ouple of breaths and think of something that gives you pleasure: a beautiful scene in nature, someone you love,” Luskin says. Dont wait for an apology. “Many times the person who hurt you has no intention of apologizing,” Luskin says. “They may have wanted to hurt you or they just dont see things th

47、e same way. So if you wait for people to apologize, you could be waiting an awfully long time.” Keep in mind that forgiveness does not necessarily mean reconciliation with the person who upset you or condoning of his or her action. Take the control away from your offender. Mentally replaying your hu

48、rt gives power to the person who caused you pain. “Instead of focusing on your wounded feelings, learn to look for the love, beauty and kindness around you,” Luskin says. Try to see things from the other persons perspective. If you empathize with that person, you may realize that he or she was acting out of ignorance, feareven love. To gain perspective, you may want to write a letter to yourself from your offenders point of view. Recognize the benefits of forgiveness. Research has shown that people who forgive report more energy, better appetite and better sleep patterns. Don
