Tolerable daily intake

Tolerable daily intake is basically the amount of something that you can safely have every day without it being harmful to your body. It's like how your mom might tell you that you can have one cookie after dinner but not the whole pack.

Scientists figure out the tolerable daily intake by doing lots of tests and experiments to see how much of a certain substance a person can have before it becomes dangerous. They take into account things like your age, weight, and overall health to determine what your perfect amount is.

For example, let's say the substance is salt. If you have too much salt, it can make your body retain water and not work as well as it should. So scientists figure out how much salt a person can have every day without it causing any problems, and that number is the tolerable daily intake.

The tolerable daily intake can change depending on new research or new information about a substance, so it's important to always pay attention to the recommended levels and talk to your doctor if you're unsure about anything.
