A new study has now discovered that a diet enriched with flaxseed decreases severity of ovarian cancer and increases survival rates in hens, which are the only animal to develop ovarian cancer in the same way as humans.
"In this study, we evaluated how a flaxseed-enriched diet affected 2-year-old laying hens (hens that have ovulated as many times as a woman entering menopause)."
The results showed that hens fed a flaxseed-enriched diet for one year experienced a significant reduction in late-stage ovarian tumors.
"Most women diagnosed with ovarian cancer have a very poor prognosis because they are not diagnosed until stage 3 or 4 when the cancer has metastasized and spread to other parts of the body," the study author said.
Hens fed the control diet had significantly more late-stage tumors that presented with fluid and metastases as compared to the hens fed a flaxseed diet. Though hens fed the flaxseed diet did not have a decreased incidence of ovarian cancer, they did experience fewer late-stage tumors and higher survival rates.
"In hens fed flaxseed, we found that more tumors were confined to the ovary and they had less metastatic spread,"
"This is an important finding as the metastases that accompany late-stage ovarian cancer are the main cause of death from this disease. If the cancer is found at an early stage, when the tumor is still confined to the ovary, women have a much better prognosis and more treatment options." the study author said.
In addition, researchers found that hens fed the flaxseed diet had better weight control which is important because obesity increases cancer risk. Both diets had equal caloric content, however the flaxseed-fed hens weighed less at six months than the control-fed hens. But at 12 months, the flaxseed-fed hens were the same weight and the control-fed hens had loss significant weight, which was indicative of their failing health.
Flax seed is available a seeds or as flaxseed oil. Buy flax seeds whole and grind them fresh when required, as once ground, the nutritional value of flax seeds deteriorates quickly. Ground flax seeds are also more easily digestible and are more nutritionally beneficial than whole flax seeds. Flaxseed oil is easily destroyed by heat, light and oxygen, so it should be kept refrigerated and eaten raw, not used to cook with.
