Summary and Conclusion

Glucose is the body’s primary source of energy, fueling everything from our muscles to our brains. While essential for life, maintaining healthy blood glucose levels is crucial for preventing metabolic disorders like diabetes. By understanding how glucose works in the body and making informed dietary choices, we can support our overall health and well-being.
