Effects of Flaxseeds and Flaxseed Oil on Cancer

flaxseed oil cancerCan you use flaxseed oil to prevent or reduce your risk for cancer?

Flaxseeds and the oil are a plant-source of the omega 3 fatty acid, alpha linolenic acid.

Omega 3 fatty acids have been documented to fight inflammation, may help boost the immune system, reduce the risk for blood clots and improving your mood.

Currently, there aren’t very many research studies involving flaxseed oil and cancer in humans.

However, there are a few animal studies that show promising benefits for this healthy oil.

 

 

Flaxseed and Flaxseed Oil may Reduce Cancer Risk

  • A study published in Mutation Research journal showed that eating a diet containing flaxseeds may reduce the risk for genetic damage by up to 30%.
  • Researchers in South Dakota looked at the incidence of colon tumors, tumor size and cancer in flaxseed or corn meal diets. Researchers found a flaxseed diet reduced the appearance of colon tumors from 83% down to 29% and the tumors shrank from 44 mm. down to 5 mm.
  • Another study published in Clinical Cancer Research looked at any effects when breast cancer patients who were awaiting treatment, received either muffins with 25 grams of ground flaxseeds or regular muffins without any flaxseeds. The researchers found that the women who received the flaxseed muffins experienced slower growing tumors. They found no significant change in the size and growth of tumors in the women who received the regular muffins.
  • Study shows flaxseed oil may reduce tumor growth – Scientists at The Department of Nutritional Sciences at University of Toronto conducted an experiment to see if a diet including flaxseed oil, flaxseeds or corn meal would have any effect on rats with cancer.  The researchers found that the rats who ate the flaxseed and flaxseed oil diets displayed an average tumor volume over 50% smaller compared to the rats that ate the corn meal diet. 

 

 

While the overall research on flaxseed oil and cancer is limited, there were some positive results seen in some of the available animal studies.

There are claims by natural health practitioner, Dr. Budwig, that following her Anti-Cancer Protocal called The Budwig Diet would help fight cancer.

The protocol involves a mixture of flaxseed oil and cottage cheese, along with a special diet, which she purports can naturally fight cancer.

However, there is ongoing controversy on the effectiveness of this diet.
