[02:57.71]WE ARE WHAT WE EAT

[03:04.69]Choosing what to eat is no longer as easy as it once was.

[03:11.14]Our eating habits have changed,as has our way of life,

[03:17.30]and the fuel we need for our bodies is also different.

[03:22.76]Traditional diets often have too much fat

[03:27.91]and too many calories for the 21st-century person.

[03:33.79]If we want to keep up with the high pace of modem 1 life,

[03:39.25]we had better learn to make the right choices about what and how we eat.

[03:46.01]Stores offer all kinds of food and snacks and we have to make many choices.

[03:53.46]When we choose what to buy and eat,

[03:57.71]we had better think whether the food will give us the nutrients 2 we need.

[04:03.88]Some nutrients help build our body and make it stronger.

[04:09.73]Protein,for example,is good for our muscles.

[04:15.50]Fish,meat and beans contain a lot of protein,Calcium,

[04:23.16]which is found in eggs,milk and other dairy 3 products,

[04:29.22]is good for our bones and teeth.

[04:33.19]We should also eat carbobydrates,the main fuel for our body,

[04:39.85]which we cna get from bread,rice and noodles.

[04:45.20]Other nutrients,such as fibre and minerals,help keep our body functioning well.

[04:52.57]Vitamins,which we can get from eating vegetables,fruit,fish and drinking milk,

[05:00.51]help our body fight disease 4.

[05:04.48]But the choices we make are not just about nutrition.

[05:09.63]Many people today

[05:13.00]make choices about their eating habits based on what they telieve.

[05:18.93]Eathing habits become part of who we are.

[05:23.16]Some people become vegetarians 5 because they believe it is healthier

[05:29.09]not to cat meat or because they think we should not kill animals for food.

[05:35.65]Others become vegans and will not eat any animal products at all,

[05:41.60]not even yoghurt or eggs.

[05:45.36]We also make choices based on how the products are grown or made:

[05:51.43]environmentally friendly food,or"eco-food",

[05:56.78]is produced by companies who have tried to use green and clean ways to grow it.

[06:03.44]Organic vegetables are those that are grown without chemicals

[06:09.61]that can be harmful to human beings or the environment

[06:14.47]Because we have so much to choose from,

[06:18.72]many companies and stores offer advice about what we should eat.

[06:24.78]Books,magazinges and television shows

[06:30.43]tell us about food and pills we should buy to become smarter,

[06:36.28]healthier and more beautiful.

[06:40.43]It is probably better,however,

[06:44.27]if we spend our time and money on buying good food and keeping a balanced diet.

[06:51.14]If we eat healthy food in the right amounts,

[06:55.69]we do not have to buy any supplements 6.

[06:59.84]The same goes for"crash diets"

[07:04.41]that some companies say will make us lose weight fast.

[07:09.74]Instead of eating expensive diet foods or going on unhealthy diets,

[07:16.79]we can simply try to eat less fat and sugar and exercise more.

[07:23.77]The best way to make sure that we will feel and look fine

[07:29.02]is to develop healthy eating habits.

[07:33.17]We ought to learn more about our body and the fuel it needs to keep fit.

[07:39.13]Only in that way will we be ready for the challenges and opportunities in life.
