Breakdown of carbohydrates into sugar is done in our body, which finally mixes in our bloodstream. Insulin is then released by our pancreas and thus sugar is transported to various cells present in human body. After absorption of sugar, level of blood sugar decreases. This causes pancreas to release one more hormone known as glucagon. This hormone orders liver to use stored sugar. This complete cycle is normal and is imperative for proper functioning of the body. Eating too much of junk food disturbs the response of insulin by increasing the amount of sugar level in the body.
