Your taste buds crave for some foods without any instinct from your brain or stomach!! This is when we call it an addiction for any food. There is no story heard anywhere that someone got addicted to apple or broccoli. But there are some foods that make it very difficult to stop eating once you have a taste of them.
The reason for this addiction is the right combination of things that make your brain give signals that you want more. These are made with a perfect ratio between refined carbohydrates and added fat.
This will cause an increase in the blood sugar level, triggered by your brain.
This happens with processed foods that contain harmful chemicals in the form of preservatives and additives.
