Scientists have produced new evidence suggesting eating lots of red and processed meat damages health. They found big meat eaters had a raised risk of death from all causes over a 10-year period. In contrast, a higher intake of white meat was associated with a slightly reduced risk of death over the same period.
The US study, based on more than 500,000 people, found those whose diet contained the highest proportion (比例) of red or processed meat had a higher overall risk of death, and specifically a higher risk of cancer and heart disease than those who ate the least.
People eating the most meat were eating about 160g of red or processed meat per day— approximately a 6oz steak. Those who ate the least were only getting about 25g per day— approximately a small piece of bacon. Just the opposite, those who ate the highest proportion of white meat had a lower risk of overall death, and a lower risk of fatal cancer or heart disease than those who ate the lowest proportion.
Meat is a major source of saturated (饱和的) fat, which has been associated with breast and colorectal cancer. In addition, lower meat intake has been linked to a reduction in risk factors for heart disease, including lower blood pressure and cholesterol (胆固醇) levels. The latest study adds to a growing body of research linking high red and processed meat consumption to an increased risk of ill health. Ed Yong, of the charity Cancer Research UK, said, “Evidence from large studies tells us that cutting down on processed food, such as bacon or burgers, can reduce the risk of dying from cancer and other diseases.”
Dr Barry Popkin of the University of North Carolina stressed there were health benefits from eating some red meat. But he added: “The need is for a major reduction in total meat intake, an even larger reduction in processed meat and other highly processed and salted animal source food products and a reduction in total saturated fat.” Dr Mark Wahlqvist, a nutrition expert from Australia, said eating small amounts of red meat—around 30g a day—provided a good source of key nutrients. He said, “Fresh, lean red meat of these amounts is likely to be of more benefit than harm.”

Are you single or married? Are you a cat or a dog owner? Do you exercise, or are you a “couch potato” (a person who sits on the sofa all day watching TV, eating and basically doing nothing)? These questions and many others are about your lifestyle.
People in the United States feel that they can choose their lifestyles and even shape their own identities. The great variety of lifestyles leads to constant national discussion of choices that people make. This freedom of choice is fun and exciting, but it also creates stress and uncertainty. In newspapers, lifestyle issues are discussed in the features or style section. In The Chicago Tribune this section is called “Tempo”. People turn to this section for lively discussion on lifestyle choices they face with regard to their personal identities, their families, and their social lives.
Many American people believe that they can make their lives happy and satisfying despite their problems. If they lack confidence or tend to feel anxious, shy, angry, or depressed, they believe that they can change themselves. Self-help books, magazines, and feature articles are filled with advice from experts about steps to take to become a happier or more satisfied person and to improve one’s self-respect. Part of this research for self-improvement is a belief that even one’s own appearance can be controlled. This is why there are so many articles in the newspaper about looking young, wearing the latest fashions, and becoming physically fit.
Lifestyle choices also involve moral and social issues. How should children be raised? How should people behave on a date? How should elderly people be treated? How can people stay happily married? All these kinds of issues are constantly discussed and are constantly changing. Not only are experts such as psychologists consulted, but stars from the political and entertainment worlds are held up as lifestyle leaders as well. In the newspaper, feature articles called profiles discuss in detail the personal lives or public work of movie stars, authors, artists, and exceptional individuals who are not stars. The lifestyle choices these people make contribute to the public discussion of all the issues that people think about.
A well-known advertising slogan is “Just do it.” In the culture of the United States, people believe that they can take action and become the kind of people they want to be and live the way they want to live.
