I READING. Read the text.
It is estimated that over one million children in the UK are obese and this has trebled over the past 20
years. The World Health Organization has described the problem of obesity as a “global epidemic" and there
are fears there will be a huge health crisis in the future. If you are overweight, you will possibly suffer from
things like heart disease and diabetes.
Food and nutrition in schools in the UK is an important issue and has a direct influence on Learners'
performance in the classroom. Poor diet has very negative effects on concentration and behavior.
Jamie Oliver, a British celebrity chef, introduced the idea of healthier school food in a TV program in
2005. As a result of this, many schools in England changed their school lunch menus. However, many
cases, schools are still not providing their Learners with a healthy, nutritious diet: school lunch
contain large amount of processed fat and sugars, and vending machines often sell fizzy drinks, chocolate
and crisps.
Schools are being encouraged to offer healthier options like chicken and rice instead of things like
hamburger and chips, and introduce vending machines selling fresh fruit, nuts or popcorn (without any
added salt, sugar, fat or honey), water, fruit juices, and yogurt drinks. These are not always popular with the
Learners, who continue to buy junk food outside school for snacks and lunch. It is important to educate
Learners about diet, nutrition and healthy eating habits. It needs to happen at school.
