Although corn and carrots don't simply dissolve into sugar as soon as you swallow, your body does convert some of the carbohydrates into glucose, which is a form of sugar needed for energy and proper health. You may "burn" the glucose to fuel immediate activity, or your body may store it in your liver or muscles for later use. If you eat more than your body needs, your liver may convert excess glucose to fat, causing weight gain.
Digestion and Carbohydrates
The digestible carbohydrates in vegetables like corn and carrots are converted into glucose more slowly than carbs from refined sugars, so they don't create the same blood sugar spike and crash that can lead to cravings and overeating. These foods also contain fiber, which is a carbohydrate that your body does not convert into sugar but needs to aid digestion. Thus, even though they're partially converted to glucose, corn and carrots are much healthier than refined sugars such as corn syrup or granulated sugar.
