Eating sugary foods and refined carbs can put at-risk individuals on the fast track to developing diabetes.
Your body rapidly breaks these foods down into small sugar molecules, which are absorbed into your bloodstream.
The resulting rise in blood sugar stimulates your pancreas to produce insulin, a hormone that helps sugar get out of the bloodstream and into your body's cells.
In people with prediabetes, the body's cells are resistant to insulin's action, so sugar remains high in the blood. To compensate, the pancreas produces more insulin, attempting to bring blood sugar down to a healthy level.
Over time, this can lead to progressively higher blood sugar and insulin levels, until the condition eventually turns into type 2 diabetes.
