A new report connects eating eggs to an increased risk of heart disease.The results follow several earlier studies that found eating eggs was generally healthy.The study collects data from six other earlier studies.It shows a 6 percent increased risk of heart disease when the number of eggs a person ate each day increased by half an egg.
Norrina Allen,an associate professor（助教）at Northwestern University said that,in the United States,eggs are generally one of the top sources of cholesterol（胆固醇）in a person's daily food.People with higher levels of cholesterol in their food are at increased risk of the development of heart disease later in life.However,Allen added that she would not say that eggs are completely unhealthy. "I'm not saying that people should take them completely out of their food," she said. "I'm just suggesting that people eat them in a proper amount."
Some experts believe the new study does not prove that eggs are causing heart disease. "Cholesterol's role in the development of heart disease has been discussed for more than 30 years," said Bruemmer,an associate professor of medicine at the University of Pittsburgh Medical Center. "This study does have clear shortcomings,including self-reporting at a single time point," he added.
Bruemmer said, "Eggs in moderation（适度）are probably acceptable from a nutritional（营养的）standpoint（立场）." "Moderation," he added, "is less than one egg a day,including eggs in foods such as bread".
Holly Andersen,a doctor at the New York-Presbyterian/Weill Cornell Medical Center,agrees that the study has "real shortcomings".One problem Andersen has with the study is that a lot of the egg-eating people in the study also appeared to be eating much meat and processed（加工的）meat. "If you're taking a lot of processed meat,it doesn't matter how many eggs you're eating," Andersen said.
Also,Andersen said, "The study can only show there is a relation between eggs eating and heart disease.But it cannot prove eggs are the cause of the disease.It may just be that people eating a lot of eggs are also taking a lot of bacon（熏肉）."
12.What does Norrina Allen agree with？______
A. Eggs are completely unhealthy.
B. Eggs should be eaten in a right amount.
C. Eggs contain the most cholesterol.
D. Eggs have no connection with heart disease.
13.What is Bruemmer's attitude towards the study？______
A. Interested.
B. Concerned.
C. Doubtful.
D. Hopeful.
14.What can we learn from Holly Andersen's words？______
A. Processed meat may cause heart disease.
B. Eggs and meat cannot be eaten together.
C. Processed meat should be avoided.
D. The study is supported by evidence.
15.What's the best title of the text？______
A. Are eggs the top source of cholesterol？
B. Do eggs cause heart disease？
C. What's the proper amount of eggs eaten？
D. Is the cholesterol to blame for heart disease？
