Introduction: (5 mins)

▪ Introductions (who you are and what you’re all about)

▪ We’ll be talking about smoothies today! Are smoothies a healthy option? They are often a quick and tasty way to get lots of fresh fruits to eat – but are all smoothies made equal?

▪ Smoothies can be full of:

o Nutrients such as Vitamin A, Vitamin C, and Manganese, which come from foods like fresh berries. These can prevent heart disease, reduce blood pressure and prevent wrinkles!

o Calcium from yogurt, milk or soymilk to help the health of your bones, teeth and nails.

o Protein from something like dairy, peanut butter, almond butter or crushed nuts will keep you fuller for longer and needed for muscle development.

o Fiber from the bulk of the fruit (instead of just the juice) which will keep you fuller for longer, help with digestion and slow down the absorption of sugar

▪ But, smoothies can also be loaded with sugar. Excess sugar in your diet can mean:

o Raising your blood sugar levels and increasing your chance of developing diabetes over time

o Lots of excess calories which will cause you to put on excess weight

Activity One – Sugary Smoothies (10 mins)

▪ Show the Smoothie Cards to the whole group – name each type of smoothie, describe it’s colour and look, and ask students if they have maybe tried it before.

o Talking Points: Do the smoothies look good? How do they make the smoothies look good in these pictures? When you buy them, do they taste as good as they look? Remind them that often the picture of the food item can sometimes be a picture of something entirely different that just looks better photographed.

• Note that all of the smoothies are the same “flavour” of smoothie – strawberry banana. As a consumer with options, would they assume that the ingredients are the same in all of these smoothies?

• Also note that some of the smoothies are different sizes – but their nutritional information with their sugar content was for one serving, which is often much smaller. Ask students, how many of you, when you buy something like a pop or a smoothie, would just drink the whole thing and not check the information on the side and drink the “appropriate” serving size? Most of us do that! So we are using the nutritional content for the whole drink.

▪ Lay the cards out in front of the students and hand out the sugar cubes. Have students work in two smaller groups to try to distribute the sugar cubes according to how much sugar they think is in each smoothie.

1 Sugar Cube = 4 grams of Sugar

▪ Have students share how many sugar cubes they think is in each smoothie – they can compare their ideas with what the other group thought. Depending on time – you can tell them the answers at this point or tell them which ones are close and give them another shot at getting it right.

Answers:

▪ Bolthouse Strawberry Banana Smoothie: 7 Sugar Cubes = 28 g

▪ McDonald’s Strawberry Banana Smoothie: 11 Sugar Cubes = 44 g

▪ Starbuck’s Strawberry Smoothie: 10 Sugar Cubes = 40 g

▪ Jamba Juice Strawberry Surf Rider Smoothie: 16 Sugar Cubes = 64 g

▪ Orange Julius 3 Berry Blast Smoothie: 26 Sugar Cubes = 104 g

▪ Ask questions about their choices – if they thought one was really high, how come? Was the size bigger? If they thought they were all going to be relatively the same, how come? Was it because the ingredients are assumed to be similar?

▪ Ask questions about the reason one may be way higher:

o Some have a scoop of sorbet or ice cream included

o Some may have flavored yogurt in it

o Some use sugary juice as their liquid

o Different “serving sizes”

o Some may have added sugar or syrup

Activity Two - Green Smoothies: (15 mins)

▪ What are some ways to make a healthier drink that still tastes good?

o Use water instead of sugary juice

o Add more fresh fruit instead of sorbet or juice for sweetness and a banana to thicken instead of ice-cream

o Add dark leafy greens for which don’t have a lot of sugar and will add more nutrients

o Try to have natural sugars instead of processed refined sugar (such as granulated sugar)

▪ Discuss some factors that may affect our food choices in our life cycle that may result in choosing less healthy foods – Why do we choose a processed sugary drink instead of a home made veggie drink?

o Schedule (eating on the run, eating fast foods due to lack of time etc.)

o Age (tend to eat more junk food as a child, peer pressure, more processed foods, lack of culinary skills)

o Economics (financially can’t afford to purchase healthier foods)

o Resources (poorly equipped kitchens, or no kitchens at all, share house)

o Flavour preferences (some people have a “sweet tooth” and some don’t)

▪ Ask if anyone knows any specific nutrients in any of the produce on display and how it contributes to our health:

o Antioxidants (Vitmain A, C, E, zinc, etc) help to slow down aging, prevent diseases such as cancer and heart disease, and reduces blood pressure. Foods are dark leafy greens, all berries, oranges, kiwi, grapefruit, broccoli, tomatoes, seeds (sunflower, pumpkin) etc

o Fibre helps bulk waste for elimination, slows down the absorption of sugar, binds to cholesterol to be eliminated. Foods that contain fibre are whole grains, legumes (beans), skins of fruit, leafy greens, and other veggies, whole grain products such as cereals

o Chlorophyll may help deodorize the bowel, cleanse the blood and increase oxygen in the blood

o Iron improves oxygen transport in the blood giving us more energy.

▪ Prepare smoothie with the assistance of students - start with some liquid in the bottom and add the rest in small chunks (especially banana and greens.)

▪ Have students peddle the bike to blend the smoothie! They can take turns peddling. Be sure to hold on tightly to the blender when they are getting on/off the bike.

▪ While bike blending, explain or ask the group about the mechanics of the bike blender or ask what the benefits of building and using a bike blender

o No carbon footprint – no emissions created from the energy production vs. emissions created from the creation of electricity to power a blender.

o Reusing old bike and blender parts – instead of adding to our landfills!

o Exercise – getting their heart rate up and burning calories!

▪ Have each student sample a taste of the smoothie

▪ Distribute the smoothie recipe
