In the future we won't have to worry about what we eat. We'll just take a tablet to give us all that our body needs and cooking will become a thing of the past.

In our modern world we often look for quick solutions to our problems. We expect to be able to achieve a great deal with little effort. But I don't believe we can apply this notion to our diet and still remain healthy. Preparing a healthy meal can take a lot of time. First you need to have fresh ingredients. Pre-packaged foods can contain a lot of unhealthy additives and so they are not as good for your body as fresh food. You also need to make sure to include a lot of different foods to make sure that you receive all of the vitamins and minerals that are very, very important to a healthy diet. It is not surprising then that some people want to find a simple solution to this in the form of a pill. Fast foods are very high in fat, sugar and salt and so we should eat them in small amounts. For some people, however, these foods have become their staple diet and as a result they are fat. If we want to stop this from becoming an even bigger problem in the future then we need to address this situation now. While vitamin tablets may be of some benefit, they are unlikely to be effective in the fight against people getting too fat. Health authorities need to increase public awareness of these issues, but we also need to be realistic. Fast food is popular not only because it is convenient but also because it is tasty. Perhaps we should strongly advise that people who eat fast food every day should at least swap fast food with fresh food on every second day. Finally, we eat for pleasure as well as nutrition and for this reason I believe that pills will never replace well-cooked food. 1 ...... nutritious...... 2 .............

Read the following passage and answer questions 1-14. The causes, diagnosis and prevention of stress

In prehistoric times, the physical changes in response to stress were an essential adaptation for meeting natural threats. Even in the modern world, the stress response can be an asset for raising levels of performance during critical events such as sports activities, important meetings, or in situations of

actual danger or crisis. If stress becomes persistent and low-level, however, all parts of the body's stress apparatus (the brain, heart, lungs, vessels and muscles) become chronically over- or under-activated. This may produce physical or psychological damage over time. Acute stress can also be harmful in certain situations.

Psychological effects of stress

Studies suggest that the inability to deal with stress is associated with the onset of depression or anxiety. In one study, two-thirds of subjects who experienced a stressful situation had nearly six times the risk of developing depression within that month. Some evidence suggests that repeated release of stress hormones disrupts normal levels of serotonin, the nerve chemical that is critical for feelings of well-being. Certainly, on a more obvious level, stress diminishes the quality of life by reducing feelings of pleasure and accomplishment, and relationships are often threatened.

Nevertheless, some stress may be beneficial. For example, although some research has suggested that stress may be a risk factor for suicide (a 2003 study found a higher risk for suicide in women reporting both low and very high stress), those with moderate stress levels had the lowest risk. Heart disease

The effects of mental stress on heart disease are controversial. Stress can certainly influence the activity of the heart when it activates the sympathetic nervous system (the automatic part of the nervous system that affects many organs, including the heart). Such actions and others could theoretically negatively affect the heart in several different ways.

Nevertheless, evidence is still needed to confirm any clear-cut relationship between stress and heart disease. For example, a 2002 study in Scotland found no greater risk for actual heart disease or heart events even in men who reported higher mental stress. In fact, higher stress was associated with fewer heart events, although men with high stress levels did tend to complain of chest pain and to go to hospital for it more often than those with lower stress levels.

Evidence has linked stress to heart disease in men, particularly in work situations where they lack control. The association between stress and heart problems in women is weaker and there is some

evidence that the ways omen cope with stress may be more heart-protective. In one study, for example, men were more apt than women to use alcohol or eat less healthily in response to stress than women, which might account for their higher heart risks from stress. Different stress factors may affect genders differently. In one study, work stress was associated a higher risk for heart disease in men, but marital stress - not work stress - was associated with more severe disease in women with existing heart problems. Eating problems

Stress can have varying effects on eating problems and weight. Often stress is related to weight gain and obesity. Mary people develop cravings for salt, fat and sugar to counteract tension and, thus, gain weight. Weight gain can occur even with a healthy diet in some people exposed to stress. In a 2000

study, lean women who gained weight in response to stress tended to be less able to adapt to and manage stressful conditions. The release of cortisol, a major stress hormone, appears to promote abdominal fat and may be the primary connection between stress and weight gain in such people. In contrast, some people suffer a loss of appetite and consequently lose weight. In rare cases, stress may trigger hyperactivity of the thyroid gland, stimulating appetite but causing the body to burn up calories at a faster than normal rate. Chronically elevated levels of stress chemicals have been observed in patients with anorexia and bulimia. Some studies, however, have not found any strong link between stress and eating disorders. Pain

Chronic pain caused by arthritis and other conditions may be intensified by stress. However, according to a study on patients with rheumatoid arthritis, stress management techniques do not appear to have much effect on arthritic pain. Some studies have clearly linked job dissatisfaction and depression to back pain, although it is still unclear if stress is a direct cause.

Tension-type headaches are frequently associated with stress and stressful events. Some research

suggests that headache sufferers may actually have some biological predisposition for translating stress into muscle contractions. Sleep disturbances

The tensions of unresolved stress frequently cause insomnia, generally keeping the stressed person awake or causing awakening in the middle of the night or early morning. In fact, evidence suggests that stress hormones can increase during sleep in anticipation of a specific waking time. However, there is some hope for sufferers in this area as relaxation therapy has been found to reduce stress levels and consequently improve the quality of sleep.

6 Model answer

1 I think in some ways we are less fit than 50 years ago because obesity was less of a problem then. But we're also healthier in that we are more aware of the risks of smoking. Although exercise has become more popular, fewer children participate in sports than 50 years ago because now they spend too much time playing computer games, which weren't around 50 years ago.

2 When I was young my mum cooked all of our meals and she would spend a tot of time in the kitchen. Now that I live by myself I find I'm too busy to cook or shop for food, so I tend to eat too much junk food nowadays.

3 I hope that they will stop making food with so many additives in and that fast food will become a lot healthier. I also think there will be more variety in fast food Test practice Academic Reading

1 True (In prehistoric times, the physical changes in response to stress were an essential adaptation for meeting natural threats.)

2 True (If stress becomes persistent and low-level, however. all parts of the body's stress apparatus (the brain, heart, lungs, vessels, and muscles) become chronically over- or under-activated.) 3 Not given

4 False (Some evidence suggests that repeated release of stress hormone disrupts normal levels of serotonin, and serotonin is 'the nerve chemical that is critical for feelings of well-being'. So stress reduces the level of serotonin.)

5 B (those (women) with moderate stress levels had the lowest risk (of suicide). A and C are wrong

because there is no comparison made between men and women this study. D is wrong because we are told: a 2003 study found a higher risk for suicide in women reporting both low and very high stress. 6 B (A and C are wrong because we are told: a 2002 study in Scotland found no greater risk for actual heart disease or heart events even in men who reported higher mental stress. B is correct because the text says: men with high stress levels did tend to complain of chest pain and to go to the hospital for it more often than those with lower stress. D is incorrect because we are told the now, did tend to complain of chest pain)

7 C (Different stress factors may affect genders differently
