Omega-3s: The Source Matters!

We’ve all heard that Omega-3 Fatty Acids are beneficial in helping to prevent or treat a number of conditions. But, now, a researcher from The University of Guelph says he’s discovered that the source of your Omega-3s is at least as important as your decision to take them in the first place.

is still to eat lots of Fish and seafood.

It has been known for some time that consumption of Omega-3s can help reduce the development and growth of cancerous tumours. But now, Prof. David Ma, of Department of Human Health and Nutritional Sciences at Guelph,has discovered that marine-based omega-3s are eight times more effective at inhibiting tumour development and growth.

“This study is the first to compare the cancer-fighting potency of plant- versus marine-derived Omega-3s on breast tumour development. There 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.”

There are three types of Omega-3 fatty acids: a-linolenic acid (ALA), eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). ALA is plant-based and found in such edible seeds as flaxseed and in oils, such as soy, canola and hemp oil. EPA and DHA are found in marine life, such as fish, algae and phytoplankton.

More research indicated…

Ma’s findings are based on studies in mice, and he agreed that further research is necessary to confirm and quantify the exceptional performance of marine-sourced Omega-3s in humans. But the evidence is strong and it seems that going ahead with taking more Omega-3s can only help your health on a number of accounts. Ma says eating a generous srerving of Fish three times a week can produce the effects that he saw in mice in the lab. But stay away from Flaxseed oil or other vegetable-sourced Omega-3s if your main concern is fighting cancer.

We’ll keep an eye out further developments on this front…
