NUTRITION!
Nutrition process
The nutrition
process involves several mechanisms in our body, we will focus in the three
most important, absorption, distribution
and excretion. Every process is developed in a part of our body as we describe:
- · Absorption: The digestive system takes the energy from the food we eat and the water of everything we eat.
- · Distribution: The circulatory system transport the nutrients all around inside our body.
- · Excretion: The urinary system throw out the wastes of our body.
In the next video,
you can see an example of how our body works
Let’s take a look
at the most important vocabulary we find here…

next activity, you have to classify the different words according to the part
of the process they belong (Absorption, distribution or excretion):
Stomach – Anus –
Blood – Urinary system – Throat – Chewing – Waste – Large intestine
Balanced diet
We know that we
have to keep a balanced diet but….what is a balanced diet? What is included?
What is the food made of? Watch the next video before you continue!
Food is made of nutrients, they
are fats, carbohydrates, proteins, vitamins, minerals and water. They are all necessary for our body to work. It is like a car, if a part is missing, it stops! Knowing what is inside our food is basic and here we will see where do we obtain the necessary nutrients from.
- Proteins. They are the muscle builders. Food like meat, eggs, nuts and fish have lots of protein.
- Fats. The reserve of energy of our body. For example, oil, cheese, nuts and certain nuts contain lots of fat.
- Carbohydrates. The fuel of our body, it gives us energy. Bread, cereals, rice, fruit and vegetables contain lots of carbohydrates.
- Vitamins and minerals. They protect us of being sick and they are necessary to the correct functioning of our body. Fruits, vegetables, nuts and natural food provide us with all of our needs.
- Water. Necessary for every process in our system.
Depending on your age, gender, life style and needs, you will need more or less of each nutrient. For example, a girl who does intense sport every day will need more energy than someone who is older and has a sedentary life style.
What do you think about a kid? Do they eat the same than an adult? Think about it and we will discuss it in class. Rememeber to investigate notes we can talk about the next day.
Activity 2.
Individually, you
will have to prepare a shopping list (minimum 20 items) and classify the
products according to their main nutrient (some products could be in two
lists). When you have finished, you will change it with a classmate and work on a food plan for you.
