Lactose is the sweet stuff that makes milk taste nice and a bit creamy.
Imagine you have a big block of soft clay. This clay isn't just one color, it’s made up of two smaller, simpler colors mixed together. Lactose is like that clay: it's made up of two smaller pieces called sugars, which are glucose and galactose.
How lactose works in milk
When you drink milk, your body needs to break down the lactose so it can use those sugars for energy. But not everyone has the special tool needed to do that job, some people don’t have enough of a helper called lactase, which is like a tiny worker that cuts the clay into its two colors.
If someone doesn’t have enough lactase, they might feel tummy troubles after drinking milk, it’s like trying to eat a big block of clay without any tools to break it down!
But for those who do have lactase, milk feels just right, sweet and easy to enjoy.
Examples
- A child drinks milk and feels sick afterward because their body can't break down the sugar in it.
