Insulin the hormone that regulates blood sugar has a strong action of causing tissue growth.  Estrogen has the same effect in breast tissue.   Normal breast tissue has receptors for both insulin and estrogen.  So if your blood insulin levels are high, a result of high blood sugar, your breast tissue cells will divide faster.

Fast cell division increases your risk of cancer, and also causes existing cancer cells to grow faster.

High insulin in the blood will increase the level of estrogen in the blood.  Estrogen when in the blood will be looking for an estrogen receptor.  Sounds logical.  It can also attach to a protein binder that prevents it binding to an estrogen receptor.  That means that there is less estrogen finding its way to breast tissue and any other tissue with estrogen receptors.

Insulin regulates the level of protein binders in the blood, it reduces the number of protein binders, so it increases the level of free estrogen in the blood, making more available to attach to breast tissue and increase the rate of cell division.

You can see that high insulin will increase the rate of breast cell growth via 2 routes.  Insulin itself speeds up cell division and tissue growth as a result, and estrogen has the same effect.  A doubling of cell growth potentials, not ideal if we are wanting to slow or stop tumour growth.

High sugar has a further knockout effect on the immune system, your first line of defence against rogue cells.  Sugar is fundamentally inflammatory.  Inflammation is the environment of tumour growth.  Keeping inflammation low or non-existent is a potent way to slow rogue cell growth.  A diet high in foods that convert to sugars quickly, high glycaemic index, is a sure way to further promote the growth of tumours.

We now have accelerated cell division via high insulin and sugar and reduced immune surveillance to detect and destroy rogue cells.

A Harvard Medical School study conducted in 2004 by Dr Horner found that women who had consumed a high glycaemic index diet as teenagers had a higher incidence of breast cancer later in life.  There is a high value in balancing the pallet so that appreciation of salty sour and bitter is increased.  Making this change early in life will greatly benefit the long term health outcomes of any woman.

More recent studies have confirmed the link between Fructose and pancreatic cancer.  The tumour cells were able to use glucose and fructose in different ways, both leading to an increase in cell proliferation.

Dr. Anthony Heaney of UCLA’s Jonsson Cancer Center, the study’s lead author said “The modern diet contains a lot of refined sugar including fructose and it’s a hidden danger implicated in a lot of modern diseases, such as obesity, diabetes and fatty liver.” While this study was done on pancreatic cancer, these findings may not be unique to that cancer type, Heaney said. “These findings show that cancer cells can readily metabolize fructose to increase proliferation.”

Other recently published studies confirm that sugar causes healthy cells to switch to tumour cells in the presence of increased sugar.  This study is both alarming and highly empowering.  The results of their study demonstrated that when sugar was removed, cells could revert to healthy cells.  This is indeed highly inspiring for those who want to have a more active role in staying healthy.

Sugar and its acidic inflammation drive dehydration in the profile of the individual who eats that diet.  This is an additional factor in tumour growth.

Many may be told that they are riding a genetic profile that gives them little control over their health outcomes.  This research is saying the opposite.  We are all able to change what is in our pantry and on our plate.  It may not be easy to change lifetime habits, however, for those who can embrace the change there is a very hopeful future. A Keto diet has the profile to give the desired low blood sugar.
