Hi, today's natural class is going to be online.

2
00:00:05,599 --> 00:00:10,779
So I've created this short video so we can go ahead and start Naturals Unit 3.

3
00:00:11,300 --> 00:00:15,560
When we were in class, we already did in some of the classes the front page.

4
00:00:16,160 --> 00:00:21,600
So we today we're just going to jump right ahead and we're going to start reading pages 30 and 31.

00:00:28,899 --> 00:00:35,619
Nutrition. Nutrition is a combination of processes which supply our body with the building materials

6
00:00:35,619 --> 00:00:42,119
and energy we need to live. What that means is that it's the process by which living things

7
00:00:42,119 --> 00:00:49,340
use food to give their bodies energy so that the body can work and it can grow properly.

8
00:00:55,109 --> 00:01:02,789
We can do nutrition because the food contains nutrients. Nutrients are simple substances

9
00:01:02,789 --> 00:01:07,430
which provide the building materials and energy our body needs to work and grow.

10
00:01:07,430 --> 00:01:13,310
and we have different types of nutrients in the first place we have carbohydrates they provide a

11
00:01:13,310 --> 00:01:19,230
fast supply of energy and they're mainly found in pulses pulses as legumes if you're not sure maybe

12
00:01:19,230 --> 00:01:25,609
you want to look that word up in your dictionary potatoes cereals including rice and cereal

13
00:01:25,609 --> 00:01:32,349
products like bread and pasta then we have fats fats provide a slower supply of energy and they

14
00:01:32,349 --> 00:01:39,189
are mainly found in oils and butter, and also you can find them in cold meat like salami, for

15
00:01:39,189 --> 00:01:46,370
example. Proteins provide building materials for growth and to repair our body. They are mainly

16
00:01:46,370 --> 00:01:54,569
found in meat, fish, eggs, milk, and pulses. We also have vitamins and minerals. They are necessary

17
00:01:54,569 --> 00:02:00,390
for our body to function properly, and they are mainly found in fruit, vegetables, and dairy

18
00:02:00,390 --> 00:02:06,769
products. Finally, we have here water. Water transports other nutrients and waste around the

19
00:02:06,769 --> 00:02:11,810
body. If you look in the picture on the right, you also have some of the milk and dairy products.

20
00:02:12,229 --> 00:02:16,729
They are also very important because they are high in calcium, an essential mineral for the

21
00:02:16,729 --> 00:02:30,099
bone growth. How does nutrition work? There are four processes involved in nutrition. These

22
00:02:30,099 --> 00:02:35,340
processes take place in different systems in our body. In the first place, we have digestion.

23
00:02:35,340 --> 00:02:40,000
This involves obtaining nutrients from our body to use.

24
00:02:40,620 --> 00:02:43,259
Digestion takes place in the digestive system.
