A healthy body is reliant upon insulin as the main regulatory agent of metabolic processes, i.e. determining your bloodsugar-levels. Insulin is vital for the glucose uptake (e.g. from sugar or starch) of muscle cells and fat tissue. But Insulin goes above and beyond that as well: it can decrease the burning of fat and enforce the substance production necessary for nutritional fat-uptake (triglycerides). Insulin influences your body’s hormones (i.e. glucagon, cortisol, somatostatin and adrenaline) and therefore effects basic organic functions such as that of your liver or pancreas.
Excessive prolonged carbohydrate uptake causes insulin-resistance
The more carbohydrates (sugars, starches) your body is supplied with, the more insulin it secretes to lower its bloodsugar-levels. Over the years this can lead to conditions such as insulin-resistance or the metabolic syndrome. Both attribute to cardiac diseases (arteriosclerosis, heart attack, coronary cardiac complications, etc.), obesity (adipositas), high blood pressure as well as high cholesterol.
Human genetic history
The human body was conditioned and built to store as much energy as it can while it can, as to have it available in times of need such as draughts etc. Since civilisation today lives with an abundance of food, the body has the tendency to store excessively.
The trap of artificial sweeteners and ‘light’ products
Not only carbohydrates are the insulin-raising culprits but also artificial sweeteners and ‘light’ products. Artificial sweeteners insinuate a high blood-sugar-level, causing an excessive insulin secretion. The actual bloodsugar-level drops on account of this, and we are hungry where we should feel well satiated, taking in more food than necessary.
