Co je to Blood Sugar a Why Does It Matter?

Blood sugar - more precisely, blood glucose - is the body 's primary fuel. Every cell relies on a steady stream of glucose to generate energie, from the neurons firing in your brain to the muscle fibers contracting during a workout. Glucose is absorbed into thee bloodsteam after you eat carhydrates, then transported to cells with thet of insulin.

How the Body Regulates Glucose

Tho human body maintaines blood glucagon with a relatively narrow range thanks to a finely tuned hadil system. Two key aveles - insulid and glucagon - work like a termostat, constantly consideling glucosi levels based on what you eat, how active you are, and their signals.
