Glucose is a simple sugar (monosaccharide) and a primary source of energy for the body. It is one of the most important sugars in the body, and it is found naturally in foods like fruits, vegetables, and honey. It is also produced in the body from the digestion of more complex carbohydrates, such as starches and sugars.Glucose is a vital energy source for the body and plays a central role in metabolic processes. Proper regulation of glucose levels is critical for overall health, and imbalances (either too low or too high) can lead to significant health issues, particularly for those with diabetes.
