Hello, my name is Mrs. Mehrin, and I'm really looking forward to learning all about amounts of food with you.

Let's begin.

Welcome to today's lesson from the unit Healthy Eating.

Your learning outcome is: I can explain why the amount of food humans eat is important.

Now, I know that learning can sometimes be a little bit challenging, but that's okay because it just means that we are going to work really hard together and we're going to learn lots of fabulous new things.

Let's begin.

Here are your keywords for today's lesson.

Now, I am going to be referring to these keywords throughout today's lesson.

However, if you find it helpful, you can pop the video on pause and have a jot down of these keywords along with the definitions.

Off you go.

Fabulous, well done.

Now our lesson is split into two parts today.

Let's begin with the first part: amounts of food.

Laura says, "I really enjoy eating sweets, but I am not allowed them every day.

I wonder why." What do you think? Why do you think Laura is not allowed to eat sweets every single day? I'll give you five seconds to think about your answer.

Off you go.

Fabulous, well done.

Now Jun says, "Well, we can ask my auntie.

She's a dietitian." What is a dietitian? Do you know? I'll give you five seconds to think about your answer.

Off you go.

Fabulous, well done.

Now, a dietitian is a scientist who studies food and they can give advice about food and eating, including what types of food to include in a balanced diet.

And here is a picture of Jun's auntie.

Now let's do a quick check-in of your learning before we continue.

What do dietitians study? Is it A, rocks; B, food; or C, materials? There's a clue in the word dietitians.

I'll give you five seconds to think about your answer.

Off you go.

Fabulous, well done.

The answer is B, food.

Now, Jun says, "My auntie says we get nutrition from food, and part of her job is to advise people on their food and nutrition choices." And here is Jun's auntie giving nutrition advice.

Now, do you know what this means? So remember, Jun said that his auntie says that we get nutrition from food, and part of her job is to advise people on food and nutrition choices.

So do you know what that means? I'll give you five seconds to think about your answer.

Off you go.

Fabulous, well done.

So a nutrient is any substance that plants or animals need in order to live or grow.

And nutrition is what you take into your body as food and the way that it influences your health.

So these words both come from the old Latin word nutrire, which means to feed or nourish.

Now, we get nutrition from the different foods that we eat, and different foods contain different nutrients, and these can affect your health in different ways.

And nutrients help to keep our bodies healthy.

And different foods give us different nutrients, which is why it's so important to have a varied diet.

And nutrients give us energy.

They help our bones and muscles to stay healthy and help our bodies to grow and repair.

Now, true or false? A dietitian cooks healthy food in a restaurant.

Is that true or false? I'll give you five seconds to think about your answer.

Off you go.

Fabulous, well done.

The answer is false.

Now let's see if you can justify your answer.

Is it because A, a dietitian advises people on their food and nutrition choices, or B, a dietitian advises people on how to get better if they're feeling unwell? Again, I'll give you five seconds to think about your answer.

Off you go.

Fabulous, well done.

It's A, a dietitian advises people on their food and nutrition choices.

Now, Jun says, "Dietitians advise us that we should eat the right amounts of different types of food, but I'm not sure why." Do you know? I'll give you five seconds to think about your answer.

Off you go.

Fabulous, well done.

Now, some foods help us to stay healthy and other foods can be unhealthy if we eat too much of them.

And humans need to eat the right amounts of different types of foods so that they can get the right nutrients as well.

Now, who do you agree with? Laura says, "You need as many nutrients as you can get from different foods." And Jun says, "You need the right types and amount of nutrients from different foods." Who do you agree with? I'll give you five seconds to think about your answer.

Off you go.

Fabulous, well done.

It's Jun who is correct.

It's not that you need as many nutrients as you can get from different foods.

You need the right types and the right amount of nutrients from different.

Alex says, "We need the right types and amount of nutrients from the food we eat.

Is this the same for children and adults? Should I eat the same amount of different foods as my parents?" What do you think? Do you think Alex should be eating the same amount as his parents? I'll give you a five seconds to think about your answer.

Off you go.

Fabulous, well done.

So nutrition from food for children is based on the same ideas as nutrition for adults.

And everyone needs the same type of nutrients, so adults and children need vitamins, minerals, carbohydrates, protein, and fat.

But children need different amounts of nutrients from food at different ages.

Alex's brother says, "The amount of each food that we should eat depends on our age and height." We need to eat the right amount of foods from different food groups.

Eating too much or too little food can be harmful to our health.

And Laura says, "I see! So sweets come from the food group high in sugars, and eating too many sweets does not provide my body with the nutrition it needs to stay healthy." Now, true or false? Eating too much or not enough of certain types of food can be harmful to our health.

Is that true or false? I'll give you five seconds to think about your answer.

Off you go.

Fabulous, well done.

The answer is true.

Now let's see if you can justify your answers because A, you should eat different amounts of different types of foods, or B, we should eat the same amount of all types of food.

Again, I'll give you five seconds to think about your answer.

Off you go.

Fabulous, well done.

The answer is A, we should eat different amounts of different types of food.

Now, humans need to eat different amounts of foods from different food groups.

So we have fruits and vegetables, dairy and alternatives, protein, carbohydrates, and fats from oils and spreads.

Now it says dairy and alternatives because some people are allergic to dairy, so you can have dairy alternatives.

Now your first task is: Alex eats a bowl of spaghetti, some chips, and a piece of toast.

What food group does Alex's food belong to and how could he make sure he's not eating too much from this group? So what I'd like you to do is to pause the video here and have a go at doing this activity.

Off you go.

Fabulous, well done.

So Sam says, "The pasta, potatoes, and bread in Alex's meal come from the food group called carbohydrates.

He needs to eat foods that contain protein and dairy too." Aisha says, "Alex also needs to eat fruit and vegetables.

He could add tomatoes, peppers, and onions to his pasta and have a salad instead of chips." Now we are onto the second part of our learning today, which is the Eatwell plate.

Now, which of these foods should humans eat most often? What do you think? I'll give you five seconds to think about your answer.

Fantastic, well done.

So fruits and vegetables make up one of the largest amounts of food in humans' diet.

Which of these foods should humans eat only sometimes? Again, I'll give you five seconds to think about your answer.

Fabulous, well done.

Humans should only eat small amounts of foods that contain a lot of fats such as oils.

Humans need some fat in their diet, but not too much.

So out of those three foods there, we should be eating the coconut oil the least.

Now, Laura says, "We can measure our food in amounts from each food group.

But how do we do this?" Do you know? I'll give you five seconds to think about your answer.

Off you go.

Fabulous, well done.

So we can use secondary sources to find out more information about amounts of food.

What is a secondary source? Again, I'll give you five seconds to think about your answer.

Off you go.

So secondary sources are texts, images, or objects created using information gathered by others.

And Lucas says, "I have used this food pyramid as a secondary source to help me to know the right amounts of each type of food to eat each day to stay healthy." So here is the food pyramid.

Now, where can we find information about amounts of food? Is it A, using secondary sources; B, a magnifying glass; or C, microscope? I'll give you five seconds to think about your answer.

Off you go.

Fabulous, well done.

The answer is A, secondary sources.

Now Jun says, "My auntie told me about a secondary source of information used by dietitians called the Eatwell plate.

Now what do you think the Eatwell plate is? I'll give you five seconds to think about your answer.

Off you go.

So the Eatwell plate is a guide based on how much you should eat from each food group.

So it's a bit like the food pyramid.

So on the food pyramid, at the bottom row has what you should eat the most of.

And at the very top is the things that you should eat the least amount of.

So on this Eatwell plate, it portions up your plate into the amounts of food that your plate should cover.

So for example, roughly about a third of your plate, just over a third of your plate should be fruits and vegetables.

About a third of your plate should be your carbohydrates, so just slightly less than your fruits and vegetables.

You've got your proteins in there, which make up the next biggest amount on your plate.

Your dairy and dairy alternatives should make up the next biggest amount on your plate.

And then your oils and your spreads should make up the least amount of your plate.

And then your foods and drinks high in fat and/or sugar should be eaten less often and in small amounts.

So it's not on your plate because it shouldn't be eaten every single day.

And if you do have it, it should be in small amounts.

Now Laura has made a list of what she has eaten over the last two days.

So she's had milk, margarine, onions, mushrooms, lettuce, potatoes, soy pieces, peach, salmon, cheese, bread, two bananas, pasta, eggs, cauliflower, rice, four strawberries, raspberries, beef, and tomato.

So Laura has put each of her foods into the correct section of the Eatwell plate.

So she's got her fruits and vegetables, her carbohydrates, her protein, her dairy and alternatives, and her oils and spread.

She says, "The Eatwell plate has helped me to see that I have eaten the right amounts of food from each group.

It's a good idea to try to keep this balance right each day to help keep your body healthy." Now, who do you agree with? Andeep says, "The Eatwell plate shows us which foods we enjoy eating the most." Izzy says, "The Eatwell plate shows us how much we should eat from each food group." And Sofia says, "The Eatwell plate shows us which foods are good for us and which foods are bad for us." I'll give you five seconds to think about your answer.

Off you go.

Fantastic, well done.

Izzy is correct.

The Eatwell plate shows us how much we should eat from each food group.

Now, which of these types of food does the Eatwell plate show us that we should eat most often? So should we be eating protein most often, dairy and alternatives most often, or carbohydrates most often? So have a look at those pictures, which one should we eat the most of and more often? I'll give you five seconds to think about your answer.

Off you go.

Fantastic, well done.

The answer is C, carbohydrates.

Now, what have you eaten in the last 24 hours? I want you to put each food into the correct section of the Eatwell plate.

So I'd like you to pause the video here and have a go at doing this activity.

Off you go.

Fantastic.

So here is mine.

So I've got my fruits and vegetables.

I've had strawberries, cucumbers, peas, onions, sweet corn, apples, tomatoes, lettuce, and peppers.

I've had some chicken, some lentils, some salmon and eggs.

I've had some milk and cheese as my dairy and alternatives, and olive oil as my oils and spreads.

And for my carbohydrates, I've had pasta, rice, bread, potatoes, bagels, and cereal.

Now here is task two.

Why is it important for humans to get the right amount of nutrition from what they eat? So I'd like you to pause the video here and have a go at doing this.

Off you go.

Fantastic, well done.

So Laura says, "Different foods give our bodies different nutrients, so it's important that we eat the correct amount of each type of food to keep our bodies healthy." Jun says, "We should try to eat less sugary foods and drinks, baked goods, fried foods, and processed meats.

These foods are high in added sugars and fats, and too much of these can be harmful to our health." Now we are on to the summary of your learning today.

A dietitian is a scientist who studies food and gives advice about food and nutrition.

Eating too much or not enough of certain types of food can be harmful to our health.

Information about amounts of food can be found by using second resources of information.

And the Eatwell plate tells us how much we should eat from each food group.

Now, you have worked really hard and done a fantastic job this lesson.

I am so proud of how well you have thought about foods that you are eating and what nutrients you need from them.

So well done.
