Приведем выдержку из задания из учебника Комарова, Ларионова 10 класс, Русское слово:
Diet: then and now
Most people are aware of the high rates of obesity in western societies today. But this is only a recent trend. In the past, obesity was rare and was only found among the rich. Why? Because then people ate little or no processed food. Their diet consisted mainly of fresh fruit, vegetables, meat, dairy products and nuts. These foods arc very nutritious because they are high in iron, protein, calcium, vitamins and. very importantly, fiber.
Today, many people in western societies, including children, cat a diet low in fresh food and high in processed foods, which arc high in fat and sugar and contain very little nutritional content.
But why don’t we eat more healthily? The answer is choice and lifestyle. Nowadays, there is a wide variety of different food types available, which makes it harder to cat healthily. But a healthy diet is not the only thing that is important for a healthy life. Physical activity is just as important. In the past, people did not need to take up sports or go to the gym to stay healthy. They exercised a lot in their everyday life. There were no washing machines nor were there any cars. People washed things by hand, they even fetched the water to do their washing with. Today, all of these things are done for us by machines. We don’t do our own washing, the washing machine docs it for us. We also dontaskt walk as much as our ancestors did.
What does the future hold? Probably more of the same. People are unlikely to change their diet or lifestyles in the future. But what we need to keep in mind is that if we dontaskt exercise more in our daily lives or choose to eat healthier foods, we will continue to have weight and health problems.
The health food pyramid and the food groups
What should my diet consist of? The food pyramid has been designed by health professionals to help us see what we should be eating and in what amounts.
Foods high in fats and sugar
Foods high in protein, iron and calcium
The servings of food indicated should be spread across the day. A balanced diet of three meals a day and two snacks should ensure that this happens. Fruits and vegetables should be fresh and sweets should be eaten sparingly. Because we need to cat as much fiber as possible, it is also important that at least half the grains you cat should be whole (as in wholegrain).
Junk food or fast food
Can I over have fast food? Eating sensibly does not mean never eating fast food. The occasional hamburger and chips is not a problem. The problem begins when you only eat junk food. Eat it as rarely as possible.
A Match the sections of the health food pyramid to the descriptions.
A Meat and bean group (2 servings per day)
В Vegetable group (5 servings a day)
C Fats / oils and sweets (no more than 6 teaspoons per day)
D Milk group / dairy products (3 cups / servings per day)
E Grain group (6 servings per day)
F Fruit group (4 servings a day)
В Read the text carefully and answer these questions.
1 Were people in the past as overweight as people today? Why / Why not?
2 Why do people today cat less healthily than people in the past?
3 In addition to diet, what else is making people overweight today?
4 Will peopletasks diets and lifestyles change in the future?
5 Which food group should we cat the most of? Why?
6 When should we eat fast food?
