VOA标准英语2009年-Western-Style Diet Brings New Health P

（单词翻译）

Over the past few years, the country has seen a proliferation of so-called "lifestyle diseases" such as diabetes¹, heart disease and cancers. Experts attribute this to rising incomes, Western diets and less physical activity.

Malnutrition² and hunger relentlessly³ stalk communities in some areas of Kenya, while in others, diabetes, heart disease, and obesity⁴ are just one bite away.

For decades, the East African country's healthcare system has focused on battling malnutrition and communicable diseases such as malaria⁵, tuberculosis⁶ and HIV/AIDS, dubbed⁷ "diseases of the poor."

Pathologist and cancer expert Dr. Geoffrey Mutuma is principal researcher for the Kenya Medical Research Institute.

"We are having a tsunami⁸, and our tsunami now is non-communicable diseases, the diseases which actually we get because of what we eat, because we have changed our diet from the traditional African food to a Western-type of food, the fast foods," he said.

Traditional African dishes contain largely unrefined maize⁹ and grains, unrefined carbohydrates¹⁰ and fresh vegetables and fruits, and are high in fiber¹¹ and low in fat and cholesterol¹².

But more and more people are consuming processed, refined and fast foods. Fast food outlets¹³ and restaurants have proliferated¹⁴ in Nairobi and other locations within the last 10 years.

Nutritionist Anne Mwangi-Thuo attributes this in part to a growing middle class that has money to spend.

"It gives you 'class' if you go and eat chips as opposed to eating ugali [a traditional maize-flour dish]. It gives you class if you can go for what is called in Kenya 'nyama choma,' roasted meat, than when you eat the beans. When they grew up, they ate a lot of the maize and beans and potatoes - they felt that that is the 'poor man's diet,'" she explained.

This middle class, and even those living in rural areas, are walking less and less. More and more people have office jobs where they sit most of the day, and few people take time out of their busy schedules to exercise.

As a result of poor diet and lack of exercise, the so-called "lifestyle diseases," including diabetes, obesity, heart disease and certain cancers, are now taking over.

According to Ministry¹⁵ of Public Health figures, non-communicable diseases contributed to more than 33 percent of deaths in 2007. The ministry estimates that 53 percent of all hospital admissions in Nairobi are due to non-communicable diseases, with diabetes contributing 27 percent of the total.

Diabetes is Kenya's number one non-communicable disease, yet has received scant¹⁶ attention, says consultant¹⁷ physician/endocrinologist and diabetes expert Dr. Eva Njenga.

"We have actually a double burden of infectious diseases and the non-communicable diseases," she said.  "Diabetes is now being linked to a level whereby we actually have more people dying from diabetes than from HIV. And that should actually ring a bell and raise an alarm for our government."

But the lack of specialized¹⁸ equipment and expertise¹⁹ makes Kenya's health-care system ill-equipped to cope with diabetes and other non-infectious diseases, says the Kenya Medical Research Institute's Dr. Mutuma.

"It is very expensive," he added.  "They are chronic²⁰ diseases, they require a lot of treatment, they require a lot of care, and we are not ready for that."

Kenyan health experts say the government cannot expect help from international donors²¹ to prevent and treat non-communicable diseases. The experts say they think there is a perception in the West that so-called "diseases of the rich" are not found in so-called "poor" countries like Kenya.
