1
00:00:00,000 --> 00:00:06,680
So, how do you apply these math concepts of estimation and measurement to nutrition and

2
00:00:06,680 --> 00:00:07,680
exercise?

3
00:00:07,680 --> 00:00:13,520
Well, to answer this question, we must first learn what good nutrition is and the benefits

4
00:00:13,520 --> 00:00:15,420
of regular exercise.

5
00:00:15,420 --> 00:00:20,560
Good nutrition is critical throughout life, but is most important for kids.

6
00:00:20,560 --> 00:00:25,520
While the body is growing, good nutrition helps to ensure optimal health.

7
00:00:25,520 --> 00:00:31,240
Every cell, every organ, and every system in the body relies on good nutrition.

8
00:00:31,240 --> 00:00:34,680
How many times have you fallen asleep in class after lunch?

9
00:00:34,680 --> 00:00:36,800
What do you typically eat for lunch?

10
00:00:36,800 --> 00:00:37,800
French fries?

11
00:00:37,800 --> 00:00:39,240
Greasy pizza?

12
00:00:39,240 --> 00:00:40,240
Donuts?

13
00:00:40,240 --> 00:00:41,240
Regular soda?

14
00:00:41,240 --> 00:00:43,600
Or even glazed honey buns?

15
00:00:43,600 --> 00:00:48,320
If you establish good nutritional habits at a young age, it will help lead to continuing

16
00:00:48,320 --> 00:00:50,320
these habits as adults.

17
00:00:50,320 --> 00:00:55,160
And remember guys, the key to anything you eat is to eat in moderation.

18
00:00:55,160 --> 00:01:00,000
That means you don't eat an entire bag of chips while watching TV.

19
00:01:00,000 --> 00:01:05,920
And exercise is an integral part of effective weight maintenance and weight loss.

20
00:01:05,920 --> 00:01:10,360
Exercise helps to control your weight by using excess calories that otherwise would

21
00:01:10,360 --> 00:01:11,960
be stored as fat.

22
00:01:11,960 --> 00:01:16,880
Regulation of body weight is dependent on the number of calories you eat and use each

23
00:01:16,880 --> 00:01:17,880
day.

24
00:01:17,880 --> 00:01:23,140
Balancing the calories you use through physical activity with calories you eat will help you

25
00:01:23,140 --> 00:01:26,780
achieve your desired weight.

26
00:01:26,780 --> 00:01:29,780
Now I'm starting to understand the importance of nutrition and exercise.

27
00:01:29,780 --> 00:01:33,300
In order to stay healthy throughout my life, I have to start maintaining a good level of

28
00:01:33,300 --> 00:01:34,900
nutrition and exercise now.

29
00:01:34,900 --> 00:01:36,780
RJ, I am so proud of you.

30
00:01:36,780 --> 00:01:38,860
You're on the right track, buddy.

31
00:01:38,860 --> 00:01:43,060
And did you know that NASA has an interest in nutrition and exercise?

32
00:01:43,060 --> 00:01:44,060
That's right.

33
00:01:44,060 --> 00:01:48,460
Astronauts living on the International Space Station undergo changes in their body that

34
00:01:48,460 --> 00:01:53,060
can affect the way they function in space and when they return to Earth.

35
00:01:53,060 --> 00:01:54,060
Think about this question.

36
00:01:54,060 --> 00:01:58,500
What can we learn in space about our bodies here on Earth?

37
00:01:58,500 --> 00:02:03,900
Also, how do we apply the math concepts of measurement and estimation to nutrition and

38
00:02:03,900 --> 00:02:04,900
exercise?

39
00:02:04,900 --> 00:02:06,460
Good form, RJ.

40
00:02:06,460 --> 00:02:11,780
Okay, while I help RJ with his exercise and nutrition program, let's go visit Dr. Scott

41
00:02:11,780 --> 00:02:15,780
Smith, a nutritionist at NASA Johnson Space Center in Houston, Texas.

42
00:02:15,780 --> 00:02:16,820
Keep going, RJ.
