【题目】Eating nuts and peanuts reduces the risk of suffering a heart attack or stroke, a new study claims. Researchers found they were linked with a reduced risk of death from heart disease among people on low incomes.And they believe their findings suggest peanuts may be a cost-effective measure to improve cardiovascular(心血管) health because they are so cheap.
However, experts cautioned today that salt-covered nuts would not have the same health benefits. Nuts are rich in nutrients and peanuts, although classified as one bean, have nutrients similar to tree nuts.
The new study, led by Dr Xiao-Ou Shu, of the Vanderbilt University School of Medicine, Tennessee, analysed various groups of people.One involved 72,000 low-income black and white men and women living in the US, the other 134,000 men and women living in Shanghai, China.In both groups, men ate more peanuts than women.In the US group, about half of the nuts consumed were peanuts, and in the Chinese group only peanut consumption was considered..
The researchers found that overall, eating nuts reduced the risk of death from heart disease.This was regardless of gender, race, body condition, smoking, alcohol consumption and conditions such as diabetes(糖尿病), high blood pressure and obesity.
In the US, the highest consumption resulted in a risk reduction of 21 per cent. In the Chinese group, it was 17 per cent.
Dr Shu said: 'We observed no significant associations between nut or peanut consumption and risk of death due to cancer and diabetes.She added the findings highlight the large public health impact of nut or peanut consumption in lowering deaths from heart disease - especially for their affordability.
The research was published in JAMA Internal Medicine.
Dr Mitchell Katz, deputy editor of the journal, added: 'Of course, peanuts are not really nuts - they are legumes since they grow in bushes, unlike tree nuts.'But who cares if they help us to live longer at an affordable price?'

一诺书业暑假作业快乐假期云南美术出版社系列答案【题目】
How do you enter a room full of strangers? Do you walk right in full of confidence? Or do you try to slip in without being noticed? ___【1】___
In life, we admire those who do their tasks confidently. We prefer people who appear to know what they are doing. But where does that confidence begin?
Developing self-confidence starts very early. It’s parents’ role to get kids on the right track toward becoming confident people. ___【2】___ That can be done by focusing on the child’s strengths. Parents should encourage their children to try new things and take risks. When children make mistakes, their parents should still let them know that they are loved. Children whose parents do these things will likely develop into confident adults. ___【3】___ So what’s the solution?
With most things in life, practice makes perfect, and that is true of confidence skills. ___【4】___
Always hold your head high and look people in the eye. Answer questions clearly and confidently.
Focus on the things that you do well, and look for opportunities to use those abilities.
Prepare thoroughly for every project. You’ll approach the task more confidently knowing that you are ready.
___【5】___ It could be a good test score or a prize from a contest. Remind yourself that one success often leads to the next.
However, all humans fail at times, and you will too. Even with efforts to try all the above, you will never be perfect. But you can learn to love and accept yourself and live your life with confidence.
Keep in mind an item that reminds you of a recent success. The more you practice them, the easier they will become. The way you go into new situations show your level of self-confidence. Our goal is to prepare students to go into the world with confidence. To help that process, parents should always offer more praise than criticism. Learning from mistakes helps you face the same situation later without fear. But self-confidence still doesn’t come easily. |
