[00:03.64]Lesson 34

[00:05.20]1.2 If you go to a fast food restaurant

[00:11.19]or a snack bar,

[00:13.00]You will probably see a lot of teenagers.

[00:16.70]Today,many teenagers are overweight,

[00:20.88]and some of this

[00:22.34]is because of their bad eating habits.

[00:25.50]Most teenagers love food with a lot of fat,oil,

[00:31.18]salt,and sugar.

[00:33.33]People often call this type of food "junk food"

[00:37.47]But bad eating habits go beyond fast food.

[00:41.24]Many teenagers find it difficult

[00:44.13]to eat healthily.

[00:45.99]Some don't have breakfast

[00:47.74]before they go to school.

[00:49.65]During the day,some don't have a proper meal

[00:52.88]for lunch.

[00:54.16]In a recent survey at one school.

[00:57.26]Scientists found that over two thirds

[01:00.23]of the students didn't follow a healthy diet.

[01:04.83]Nearly half of the students

[01:07.55]didn't like vegetables,

[01:09.57]and many of them didn't like to eat fruits.

[01:13.45]They preferred to eat food with a lot of salt,

[01:17.11]sugar,or fat.

[01:19.69]Parents today also worry

[01:21.81]about their children's diet.

[01:24.61]Some doctors give the following advice.

[01:28.51]Teenagers shouldn't eat too much junk food.

[01:33.43]Teenagers shouldn't eat food with too much salt

[01:38.14]Salt can cause high blood pressure

[01:40.93]in the future.

[01:43.22]Teenagers should eat food

[01:46.03]with less fat,oil and sugar.

[01:49.80]Teenagers need to eat some fruits

[01:52.59]and vegetables every day.

[01:55.17]Fruits and vegetables are rich in vitamins

[01:59.16]and have little fat.

[02:01.55]Teenagers need to drink more milk.

[02:05.22]Milk will help their bones grow.

[02:08.84]Teenagers need to eat breakfast every day.

[02:13.13]This is good for their body and mind.

[02:20.26]2.2 I really need your help.

[02:24.95]I'm 14,and I weigh over 70 kilograms.

[02:29.58]I worry about my weight.

[02:31.30]What can I do?

[02:33.07]First,don't worry too much,

[02:35.79]but at the same time,

[02:37.50]you should pay attention to your health.

[02:40.14]You need to look at two things;

[02:42.95]what you are eating

[02:44.89]and how much exercise you do.

[02:47.86]You should talk to a doctor

[02:49.92]about what you can do to lose weight.

[02:54.56]Will I do better in school if I eat breakfast?

[02:58.45]Yes,there is a relationship

[03:00.75]between eating healthy breakfast in the morning

[03:03.82]and how well you do in school.

[03:06.36]You ability to work and learn

[03:08.93]depends on the sugar in your blood.

[03:11.72]This special sugar affects how much blood

[03:14.84]gets to your brain.

[03:16.64]If your brain doesn't get enough blood,

[03:19.83]it is harder for you to work and learn.

[03:24.37]I drink lots of soda,

[03:26.71]but my mom wants me to drink more water.

[03:29.88]How much water should I drink a day?

[03:32.80]Your mom is right.

[03:35.15]Soda has a lot of sugar.

[03:37.62]You should drink enough water,

[03:39.77]usually around six to eight glasses a day.

[03:43.77]This will help your body stay healthy.
