Is it food mostly water?

Magic water science.

  • Is it food mostly water?
  • Not all food is mostly water, but some foods like fruits and vegetables like watermelon and cucumber are mostly water,. Because of that they’re so juicy and refreshing! Some other foods, like bread, meat, and cheese, don’t have much water in them. They’re mostly made up of other things, like protein and carbohydrates.

Thy this: The experiment described below will show you why the fruits and vegetables are mostly water.

All you need is: an apple (potato, orange or other similar fruit or a piece of raw), meat, lettuce leaf.

Step 1: Grate an apple (or the fruit you have or the piece of raw meat).
Step 2: Let a lettuce leaf stand in the air.

What you will see: Water (juice) will be pressed or squeezed out. The lettuce will wilt and grow smaller as the water in it dries up.

Why: Most of our foods contain large quantities of water. Potatoes are 3/4 water. Green vegetables, such as lettuce, are 95% water. Beef is more than % water. Men and animals are made up of 60% to 70% water. Water is necessary to sustain life.

Did you manage to see how the size of the apple (or the piece of meat) decrease after the squeezing? Do you know why?
Yes. That’s true: It’s because of the missing water. As you see above green vegetables are 95% water.

Now can you try to answer the question: Why are dehydrated foods-foods with the water removed-are used when it is necessary to save space?
