Refined Carbohydrates and Breast Cancer Risk
As I have mentioned in a previous article Practical Breast Cancer Estrogen Reduction Tips, for many breast cancers, excess estrogen production is the key stimulator to the disease. When in balance, estrogen is an essential and healthful hormone. It is necessary for strong bones, a healthy heart, youthful skin and a good memory. However, when out of balance and in excess, estrogen plays a major role in breast cancer production.
Therefore, the main objective of an effective breast cancer prevention and breast cancer healing diet program is estrogens detoxification. You MUST DETOXIFY ESTROGEN to prevent and heal breast cancer.
To limit excess estrogen production, it is vital to reduce your intake of refined carbohydrates
Rapidly absorbed carbohydrates are associated with postmenopausal breast cancer risk among overweight women and women with large waist circumference. Carbohydrate intake may also be associated with estrogen receptor–negative breast cancer.
A new study published in the journal Cancer Epidemiology, Mile Markers, and Prevention is presenting evidence of the link between the consumption of refined carbohydrates and breast cancer. This case-controlled study looked at the dietary habits of over 1,800 women in Mexico, and found that those who got 57% or more of their total energy intake from carbohydrates showed a 220% higher risk of breast cancer than women with more balanced diets.
This study shows that foods with high glycemic index values — that is, foods that more quickly raise blood sugar levels in the human body — actually accelerate the growth of breast cancer cells and tumors in the human body. Researchers involved with the study propose that the correlation between the consumption of refined carbohydrates and breast cancer could be related to elevated levels of insulin and the fact that many breast cancer tumors are encouraged and supported by high levels of insulin in the body.
Both normal breast cells and cancer cells have insulin receptors on them. When insulin attaches to its receptor, it has the same effect as when estrogen attaches to its receptor; it causes cells to start dividing. The higher your insulin levels are, the faster your breast cells will divide; the faster they divide, the higher your risk of breast cancer is and the faster any existing cancer cells will grow.
The problem with refined carbohydrates
Carbohydrates in our diets affect the body’s levels of blood glucose (blood sugar) and the hormone insulin. Several lines of evidence suggest that insulin levels may directly or indirectly affect breast cancer risk. This hypothesis has prompted research on dietary carbohydrates and their possible relationship to breast cancer risk.
The glucose absorbed into the blood stream after the digestion of carbohydrates stimulates the release of the hormone insulin from the pancreas. Insulin affects the action of other hormones in the body including insulin-like growth factor (IGF) and possibly estrogen. A number of studies have suggested that higher blood levels of IGF may be linked to an increased risk of premenopausal but not postmenopausal breast cancer risk. Increased levels of estrogen in the body have been clearly linked to increased breast cancer risk. In laboratory studies, insulin has been shown to increase the proliferation of normal and cancerous breast cells.
Excess insulin in the bloodstream prompts the ovaries to reduce SHBG – the binding proteins, thus increasing levels of free estrogens – which can float around and enter target tissues.
Eliminate from your diet refined white flour, refined white sugar, milled grains, and ingredients like high-fructose corn syrup and any other refined and overly processed grains.
