\"\"When it comes to cancer prevention, Omega-3 fatty acids from fish pack a stronger punch than flaxseed and other oils, new research has found.<\/p>\n

Marine-based omega-3s are eight times more effective at inhibiting tumour development and growth than plant-based sources, said the study published in the Journal of Nutritional Biochemistry.<\/p>\n

\u201cThis study is the first to compare the cancer-fighting potency of plant-versus marine-derived Omega-3s on breast tumour development,\u201d said David Ma, Professor at University of Guelph in Ontario.<\/p>\n

\u201cThere is evidence that both Omega-3s from plants and marine sources are protective against cancer and we wanted to determine which form is more effective,\u201d Ma said.<\/p>\n

There are three types of Omega-3 fatty acids: a-linolenic acid (ALA), eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA).<\/p>\n

ALA is plant-based and found in such edible seeds as flaxseed and in oils, such as soy, canola and hemp oil.<\/p>\n

EPA and DHA are found in marine life, such as fish, algae and phytoplankton.<\/p>\n

The study involved feeding the different types of Omega-3s to mice with a highly aggressive form of human breast cancer called HER-2.<\/p>\n

Ma exposed the mice to either the plant-based or the marine-based Omega-3s.<\/p>\n

\u201cThe mice were exposed to the different omega-3s even before tumours developed, which allowed us to compare how effective the fatty acids are at prevention,\u201d said Ma.<\/p>\n

Overall exposure to marine-based omega-3s reduced the size of the tumours by 60 to 70 per cent and the number of tumours by 30 per cent.<\/p>\n

However, higher doses of the plant-based fatty acid were required to deliver the same impact as the marine-based Omega-3s, the study said.<\/p>\n

Omega-3s prevent and fight cancer by turning on genes associated with the immune system and blocking tumour growth pathways, said Ma.<\/p>\n

Based on the doses given in the study, humans should consume two to three servings of fish a week to have the same effect, he said.<\/p>\n
