Routinely eating products that contain sugar leads to a vicious sugar-craving cycle. First, sugars are absorbed into our blood and travel to the brain. Then, the sugar in the brain releases a chemical called serotonin that produces a sense of happiness and wellbeing. Next, as our sugar blood levels fall due to insulin production and sugar absorption, we move from a hyperactive state to more of a tired, irritable and weak state. This causes concentration levels to fall, and our cells begin to become acidic. Our brain then once again sends a message that we need more sugar, and the cycle repeats itself. Cutting refined sugars out of your diet, or at least decreasing them, will help you avoid this cycle and feeling your best.
