Here's a simplified explanation:
* You eat food containing carbohydrates: This could be bread, pasta, rice, fruits, vegetables, and more.
* Your digestive system breaks down carbohydrates: This happens with the help of enzymes.
* Carbohydrates are broken down into glucose: Glucose is a simple sugar that your body can easily use.
* Glucose enters the bloodstream: It's then transported to cells throughout your body.
* Cells use glucose for energy: This process is called cellular respiration.
So, while food itself doesn't turn into sugar, the carbohydrates in food are broken down into glucose, which is a form of sugar that the body can utilize.
