P.O.W. Nutritional Data

Data is everywhere... especially in your cupboards and in your fridge! It is the law in Canada that all packaged food include nutritional data. The number of calories (energy that a food gives you) is listed, and other nutritional data is recorded in two ways:

1) The amount of fat, cholesterol, sodium, fibre, sugars, and protein is recorded by weight (in grams or milligrams), and...

2) as a percentage of your daily value (E.g. if it's recommended that you get no more than 2400 milligrams of sodium per day, the food label here shows that drinking this bottle of liquid accounts for 26% of that daily amount)
 
In this week's POW, you'll combine your skills in data management and begin to think about percentages as representations of fractional numbers.

Your Task:
Pick 10 of your favourite packaged food items from your cupboards/fridge (be careful not to let refrigerated food spoil - ask a parent first)


Create a data table to show how many of your chosen items:
- have more than 25% of your daily sodium per serving
- have less than 10% of your daily fibre
- have more than 5% of your daily fat

Now, based on labels and the data you've collected, calculate what the approximate recommended daily values of sodium, fibre, and fat. (e.g. If 620 mg is 26% of daily value, how many mg is 100% of the daily value?)

Show all calculations!

Here's a video resource to help you review how to calculate percentage. We will also be reviewing percentages in class this week.
