Fish omega-3 exceeds vegetable for cancer prevention

Fish omega-3s have a greater activity in preventing cancer than those of plant origin

There are three main omega-3 fatty acids: linolenic acid (ALA), eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). The ALA is of plant origin and is found in edible seeds such as flax seed and in oils such as soy, canola and hemp oil. EPA and DHA are found in the marine world, such as fish, algae and phytoplankton.
This study compares the ability to fight cancer of plant-based omega-3s compared to marine cancers in particular to prevent breast cancer development. The results show that marine-based omega-3s are eight times more effective in inhibiting tumor growth and growth.
Published in the Journal of Nutritional Biochemistry 2018, the study was performed on mice with a highly aggressive form of human breast cancer called HER-2 and affecting 25% of women with unfavorable prognosis. Sea-borne omega-3 intake reduced the size of tumors by 60-70% and the number of tumors by 30%.
