Fuel facts πŸ’‘

⚑

Food is fuel

Your body is like a car. Food is the fuel. Good fuel makes a good day.

πŸ“ˆ

Steady fuel

Fruit, veggies, protein and whole grains give energy slowly. You stay happy and focused.

πŸ“‰

Sugar spike

Sugary drinks and candy zoom you up fast... then you crash. Tired and grumpy!

🧊

Count the cubes

One sugar cube is about 4 grams. One can of soda has about 9 cubes!

πŸ’§

Best drinks

Water or milk. A juice box is mostly sugar water with no fiber.

🍱

Smart lunchbox

Pick 1 fruit, 1 veggie, 1 protein, 1 grain... and water.

    If the judges ask...

    Why is an apple green if it is sweet? "Apple sugar comes with fiber, so it goes into your body slowly."

    How did you make the app? "It is a web page. HTML makes the buttons, JavaScript is the brain. It works on any computer."

    What is the sugar rush meter? "0 means no sugar. 10 means the sugar hits super fast."

    Is it safe? "Every student has a secret code. Only the teacher can change names and codes."
