The list of problems caused by sugar in all its forms just goes on and on. If you hadn’t previously thought of sugar as a cancer trigger, think again.
The reader’s digest version: when we eat sugar, or white flour, or foods with a high ‘glycemic index’, the blood levels of glucose rise rapidly. The body immediately releases a dose of insulin to enable the glucose to enter the cells. The secretion of insulin is accompanied by the release of another molecule, called IGF (insulin-Like growth factor), whose role it is to stimulate cell growth.
And therein lies the root of the cancer-sugar problem.
Insulin and IGF not only stimulate the growth of cancer cells but also their capacity to invde neighboring tissues. In addition, insulin and IGF promote inflammation, which also stimulates cell growth and acts in turn as fertilizer for tumors.
