Breast Cancer: Omega-3s Fight Post-Disease Tiredness and Fatigue

Breast Cancer: Less Fatigue After Illness with Fish Oil Supplements

The sense of tiredness and fatigue felt by women who have survived breast cancer can be fought with a diet rich in Omega-3. This is demonstrated by a study conducted by Dr. Rachel Ballard-Barbash, from the U.S. National Cancer Institute. The results were published in the Journal of Clinical Oncology. The author explains that the intake of Omega-3 fatty acids increases daily energy reserves and reduces the feeling of tiredness, heaviness, and fatigue caused by oncological therapy. This state of discomfort can persist even years after the end of medical treatment. Omega-3s are found in high concentrations especially in fish:

  • salmon
  • mackerel
  • sardines
  • anchovies
  • herring
  • tuna
  • halibut
  • swordfish
  • trout
These fatty acids are also present, albeit in smaller amounts, in plant sources:
  • flax seeds and flaxseed oil
  • nuts and cereals
  • leafy green vegetables
  • legumes
  • algae
Ballard-Barbash emphasizes that Omega-3 fats are preferable to Omega-6 found in vegetable oils, margarine, sweets, snacks, and fast food.



Breast Cancer Fatigue/Omega-3 Diet: The Study

The relationship between "Omega-3 intake/decreased fatigue" was clarified in a study of 633 breast cancer survivors. Overall, 42% of them reported symptoms of fatigue and exhaustion even 3 years after completing therapy. Patients who took more Omega-3, especially fish oil capsules, reported feeling less discomfort (only 23% saw no significant improvement).


Breast Cancer: Omega-3 to Improve Quality of Life

This study opens new perspectives on the role of a healthy diet, particularly with foods containing Omega-3, as a remedy for fatigue and exhaustion post-illness in patients. "It is necessary to eat fish at least twice a week," specified Dr. Ballard-Barbash at the conclusion of her presentation. This should be combined with regular physical exercise and sleep. This research also adds another piece to the puzzle regarding the benefits of Omega-3 for breast cancer.
