Sugar is definitely a hard habit to break. For me, it really helped to understand what sugar does in the body, and how it's not necessarily the sugar that's a problem as much as how our bodies respond to it. Elevated blood sugar leads to elevated insulin levels. It's really the body's response with insulin that causes most of the problems in our system. Granted, insulin is necessary for life, but when levels get high and stay high due to our over-consumption of carbohydrates, that's where significant health problems start, like insulin resistance, obesity, diabetes, heart disease and atherosclerosis, kidney disease, cancer, and a Host of neurological problems.
