Glucose and the Onion Free Diet

Glucose is a monosaccharide, often referred to as a simple sugar. It is a crucial energy source for the body and is commonly used in food manufacturing as a sweetener, or as a component in glucose syrups. Though glucose can be derived from various starches, it is typically sourced from corn. However, it can also come from wheat, potatoes, or tapioca, especially when labeled as such.
