After a meal, why doesn’t your body use all the glucose straight away?
Your body uses some blood sugar for energy now. It can also save some in the liver and muscles for later.
Quick quiz
Which statement is correct about glucose after your body breaks down carbohydrates?
- A. It must all be used immediately.
- B. Some may be stored in the liver and muscles for later.
- C. It only comes from sweets.
Correct answer: B. Glucose is a main energy source, but the body can also store some for later use.
How it works in simple terms
Carbohydrates are one of the three main nutrients in foods and drinks. Foods such as rice, bread and fruit contain carbohydrates.
Your body breaks carbohydrates down into glucose, often called blood sugar. Glucose can then be used by cells, tissues and organs for energy.
Not every bit needs to be used at once. Some can be stored in the liver and muscles, ready for later. It is a little like keeping some money in a savings pocket instead of spending every ringgit at once. This comparison only describes the idea of saving some for later.
One useful thing to remember
Blood sugar is not only about sweet foods. Your body can make glucose from carbohydrates and use it now or store some as needed.
