Fish oils dramatically change gut bacteria for better health
In a study from the University of Gothenburg, scientists have shown how fish oils seem to exert a healthy influence in our bodies, not just directly, but through the involvement of ‘good’ gut bacteria.
Fish oils have long been associated with good heart condition, mental health, longevity and improving the outcome of cancer, even preventing it. For example, it is known that fish oils can have an effect on the telomeres at the ends of DNA chains. The length of telomeres is associated with ageing. Another benefit is their ability to reduce the risk of cachexia, which is caused by taking chemotherapy drugs.
But a major health benefit of fish oil tablets is their ability to reduce chronic inflammation in the body. Chronic inflammation is invariably the precursor to chronic illness.
One mechanism is their direct ability to down-regulate an enzyme called Cox-2 known to stimulate localized cellular inflammatory hormones called eicosanoids made in the nuclear envelope of every cell in the body.
However, this new research showed that feeding animals with either a high ‘bad’ fat diet or a fish oil diet resulted in significantly different gut bacteria. Whereas the consumption of bad fats can produce a microbiome over-populated by gut bacteria that are inflammatory, the consumption of long chain omega-3 from fish or krill oil produces colonies of important anti-inflammatory gut bacteria..
We have long recommended on our websites that almost everybody from the young to the old, should take a daily fish oil or a ‘clean’ krill oil supplement.
Chris Woollams advises readers should be clear that omega-3 from flaxseed (which is short-chain) does not have the same benefits as omega-3 from fish or krill oil (which is long-chain).
