Taking omega-3 fish oil supplements may increase the risk of prostate cancer



I don't really know what the world is turning into,at 1st it was advise to be used and now this same scientist that came up with the idea are also right now going against it.our world is changing very fast.

Fish-oil supplements credited with a range of health benefits could trigger prostate cancer. Experts found that omega-3 fatty acids may raise the risk of the most lethal form of the disease by more than 70 per cent.

Doctors have strongly  warned against omega-3 pills, and recommended eating just one or two meals of oily fish per week. Fish-oil supplements are said to protect against heart attacks and strokes, stave off arthritis, boost brain power and prevent behaviour disorders in children.

 Scientists found that those with the highest levels of omega-3 in their blood were 71 per cent more likely to develop fast-growing, hard-to-treat prostate tumours. They were also more likely to contract the slower, less deadly form of the disease, with the overall prostate cancer risk raised by 43 per cent.

It was also reported that using this food supplement could change  but omega-3 may restrict the immune system, or damage our DNA.It is unclear how fish oil could trigger tumours.


 It is also unclear if it helps tumours to grow and spread. The finding came amid a wider research project of more than 2,000 men, examining whether supplements of vitamin E and the mineral selenium can help prevent prostate cancer – the most common cancer in British men, killing more than 10,000. 

Selenium provided no benefit, and vitamin E increased the odds of contracting the disease. Dr Kristal said: ‘As we do more and more of these studies – and I have been involved in them most of my career – we find high doses of supplements have no effect or increase the risk of the disease you are trying to prevent. ‘There is not really a single example of where taking a supplement lowers chronic disease risk.
