Topic 2. Nutrients

How do you feel right now?

😒🙁😐🙂😃

Diet and Fibre

Give me one thing you saw on the food labels.

OPENING STATEMENTS

Protein, carbohydrate and fat are nutrients.

Nutrients are substances found in food, that you need to stay healthy. 

You do not eat all the time, but you need energy all the time. You get almost all of your energy from the carbohydrates and fats that you eat. You can also get energy from protein if you run out of carbohydrates and fats.

Does this meal have all expected nutrients that the body needs?

NO

YES

The rice contains a lot of starch. Starch is a type of carbohydrate. After you have eaten starch, the body breaks it down to make a sugar called glucose. 

The chicken and beans contain a lot of protein. Protein is important

for making new cells in the body. So you need protein to help the body to grow, or to repair itself if it gets damaged. Protein is also needed to make haemoglobin and antibodies.

The avocado contains fats and oils. Fats and oils are very similar, but fats are solid at normal temperatures and oils are liquid. Fats and oils give you energy. They are also needed to make cell membranes.

You may remember that glucose is the fuel that your cells use for respiration, to release energy. So starch, sugar and other carbohydrates are needed to give you energy.
