What is Food?

So I am taking an online course (for fun) called “Sustainability of Food Systems: A Global Life Cycle Perspective”. One cool thing that I learned today was how to calculate the moisture content of any food. But I won’t get ahead of myself, let’s start with the basics.

What is food? Food is…

  • Things that give us nutritional value
  • Things that gives us energy
  • Things that taste good to us
  • Things that are not poisonous

Food is made up of some basic components. This helps create an amazing diversity of foods we have today.

  • Water
  • Carbohydrates
  • Proteins
  • Fats

Here is a question for you. What do you think has more water a cucumber or milk?

If you guessed cucumber, you are correct! Here is how you calculate how much water each one has. Let’s take a look at the nutrition label for both foods.

1. Look at the Total Fat, Carbohydrate and Protein for Cucumber. Add all the grams together, here is how:

Total Fat = 0g

Total Carbohydrate = 3g

Protein 1g

TOTAL: 4g

2. Now subtract 4 from the Serving Size (133 g), this will equal to 129. Divide 129 by 133, and you get 97%.

Cucumber Moisture Content is 97%

Now, let’s calculate moisture content for milk.

1. Look at the Total Fat, Carbohydrate and Protein for Milk. Add all the grams together, here is how:

Total Fat = 8g

Total Carbohydrate = 13g

Protein = 8g

TOTAL: 29g

2. Now subtract 29 from the Serving Size (244 g), this will equal to 215. Divide 215 by 244, and you get 88%.

Milk Moisture Content is 88%

So side-by-side comparison: Cucumber moisture content is 97% and Milk is 88%.

Cool huh? Now you can calculate moisture (water) content of your favorite foods. Use this website to find nutrition labels and compare!
