Healthy Eating

 

Canada Food Guide, four food groups

1.     Fruit and vegetables

2.     Protein (meat, beans, nuts)

3.     Carbohydrates (rice, noodles, bread, pasta)

4.     Milk/products (milk, cheese, ice cream)

5.     Junk food (taste good, no real nutritious value)

 

We need to eat a balanced diet everyday. This is important for teenagers

- puberty (girls: age 11 to 18; boys: age 12 to 19)

 

Why a balanced diet?

- Protein: build muscle, to make you stronger, endurance

- Carbohydrates: give us energy so we can work efficiently during the day

(too much carbohydrates: the side effects are the 

a.     person will become fat/over weight. Carbohydrates turn into fat under the skin if we don’t do enough exercise

b.     later on, they may develop diabetes (In Chinese = sweet pee disease)

c.     carbohydrates turn into sugar after it is absorbed by the body

- Milk/products: bone building, you will get taller and stronger in the next 8 years

d. Milk is a good source of calcium. Chocolate milk has a lot of sugar (as much sugar as a glass of orange juice)

e. ice cream is great on a hot day, really fattening (tasty ice cream 40% milk fat). Should not eat that everyday. Try yogurt instead

- Fruits and vegetables: plant cells – contain cell wall (animal cells do not have cell wall). 

Cell wall – source of fibre. Fibre helps the digested food to move from your stomach to intestines out of your body (help you POO everyday)

            f. contains a lot of vitamins and minerals – help you to stay healthy (harder to get sick)
