BLOOD SUGAR LEVELS: Your #1 Key to Weight, Mood and Vitality – and the Prevention and Treatment of Diabetes, Cardiovascular and Hormone Related Problems ©
Your survival depends on cells receiving fuel in the form of just the right amount of glucose or blood sugar. It is the job of the hormone insulin to courier this into cells. The Brain is your most glucose hungry organ and the first to feel its lack. All carbohydrates – from vegetables, fruits, nuts, seeds, grains or legumes – eventually get broken down into glucose. What differs is the speed at which they do this.
Individual foods have been measured in this regard and placed on a scale called the Glycemic Index or GI. Carbohydrate foods that are slow to break down – such as Legumes (dried peas, beans and lentils; see TIPS), nuts, seeds, most vegetables and fruits, plus hearty, crunchy wholegrain products – are termed low GI. Those that digest rapidly into glucose such as Sugar, most white rice, and finely milled bread, baking and cereals (of one highly refined, uniform texture) are high GI.
Eating too many high GI carbs at a meal stimulates a surge of excessive glucose. The pancreas then produces and releases more insulin as extra courier vans. Over time though, high levels of insulin are life threatening and the cells start to refuse it entrance. But by becoming resistant to insulin they are also unable to access its critical glucose fuel.
