Though science is not
exactly sure why cancer survivors are sometimes left with fatigue,
evidence suggests that chronic inflammation may have something to do
with it. The good news is that omega-3 fatty acids are believed to
decrease inflammation, especially when omega-3 replaces at
least
some omega-6 fats that are common in the American diet.
Researchers
studied the relationship between fatigue and omega-3 in 633 cancer
survivors and found that of the 42 percent of the women who
suffered fatigue for three years after their diagnosis of breast
cancer, the most common denominator was a high blood level of CRP, a
protein linked to inflammation.
Of all the women who ingested
higher amount of omega-3, predominantly through fish oil supplements,
then omega-6, 23 percent were fatigued, while 49 percent of women who
had low omega-3 intake, especially when compared to omega-6 intake,
were fatigued, the Chicago Tribune reported.
Omega-3 fatty
acids are most commonly found in fish like tuna, salmon, and
mackerel. For those who can’t or don’t eat fish, fish oil
supplements are available.
Researchers believe that the
evidence warrants further study through randomized clinical trials
for either fish oil supplements or dietary intake of
omega-3.
