[单项选择]How do we get more young people to increase their consumption of iron-rich foods Many nutritionists are advocating the fortification of a number of foods. This may help, but I contend that we should also intensify our efforts in nutrition education among our young people. I simply do not buy the argument that it is futile (无益的,无效的) to try to change eating habits. Once an intelligent person—and this includes adolescents — understands the need for a healthy diet, I think he or she will act accordingly. As for specific actions, I suggest that blood hemoglobin (血红蛋白) should be checked as a routine part of a youngster’s yearly physical examination. It should contain at least 11 grams per 100 milliliters (毫升) of blood for a girl and at least 12 grams for a boy. If it is any lower, the physician probably will prescribe an easily absorbed iron supplement.
Adolescent—and everyone else—should cut out highly processed foods and drinks, which may be low in iron and other nutrients. Read the l
A. the importance of diet
B. the need of iron
C. adolescents’ eating habits
D. blood hemoglobin
[不定项选择题]共用题干
Geology and Health
1. The importance of particular metals in the human diet has been realized within 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 serious 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 leached from rock and soil. Thus the geology and geochemistry of the environments have effects on the chemis-try 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 naturally 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 chil-dren are particularly exposed to metal-rich topsoil in 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 metals 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 possess 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 polluted 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.
Some diseases is connected with deficiency of_______.
A.industrially polluted soils
B.rock and soil chemistry
C.naturally polluted soils
D.the pathways of metals into the food chain
E.the element of iodine
F.the persistence of heavy metals
