Fish-derived omega-3 ‘better than flaxseed at preventing breast cancer’

Omega-3 from fish is more effective at preventing breast cancer than flaxseed, a new study has revealed.

The research, conducted by the University of Guelph, Canada, found that marine-based omega-3 is eight times more effective at inhibiting tumour development and growth.

Professor David Ma, from the university’s Department of Human Health and Nutritional Sciences, said his team’s study is the first to compare the potency of plant-derived omega-3 to that from fish on breast tumour development.

The study involved feeding different types of omega-3 to mice with a highly aggressive form of human breast cancer called HER-2. The researchers explained that HER-2 affects 25 per cent of women and has a poor prognosis.

According to Professor Ma, overall exposure to marine-based omega-3 reduced the size of the tumours by 60 to 70 per cent and the number of tumours by 30 per cent. Higher doses of the plant-based fatty acid were required to deliver the same impact as the marine-based omega-3.ADNFCR-2094-ID-801844269-ADNFCR
