Saliva has enzymes called amylase which breaks down polymers of starch. By the time starch is getting to the stomach it has been broken down to glucose.

This glucose is then absorbed into the blood stream then the blood transports it to your body cells. Body cells absorb the glucose for the use of creating energy.

Carbohydrates can be found in rice, bread, fruits, and of course, sweets such as candies, chocolates, ice cream, and cakes. Yes, the best things in this world are usually high on carbohydrates.
