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.

Marine-based omega-3s are eight times more effective at inhibiting tumor development and growth than plant-based sources, said the study published in the Journal of Nutritional Biochemistry.

“This study is the first to compare the cancer-fighting potency of plant-versus marine-derived Omega-3s on breast tumor development,” said David Ma, Professor at the University of Guelph in Ontario.

“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,” Ma said.

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.

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

Ma exposed the mice to either the plant-based or the marine-based Omega-3s.

“The mice were exposed to the different omega-3s even before tumors developed, which allowed us to compare how effective the fatty acids are at prevention,” said Ma.

Overall exposure to marine-based omega-3s reduced the size of the tumors by 60 to 70 percent and the number of tumors by 30 percent. Pixabay

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.

Omega-3s prevent and fight cancer by turning on genes associated with the immune system and blocking tumor growth pathways, said Ma.

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. (IANS)

Daily meditation can help improve mood and sleep in teenagers suffering or recuperating from cancer, a promising research shows.

Mindfulness-based meditation could lessen some symptoms associated with cancer in teenagers, according to the results of a clinical trial intervention led by researchers at University of Montreal and its affiliated CHU Sainte-Justine children’s hospital.

The process focuses on the present moment and the connection between the mind and body.

Adolescents living with cancer face not only the physical symptoms of their condition but also the anxiety and uncertainty related to the progression of the disease and the anticipation of physical and emotional pain related to illness and treatment.

The researchers asked 13 adolescents with cancer to complete questionnaires covering mood (positive and negative emotions, anxiety and depression), sleep and quality of life.
The group was divided in two. The first group of eight adolescents were offered eight mindfulness-based meditation sessions and the remaining five adolescents in the control group were put on a wait-list.

After the last meditation session, patients from both groups filled out the same questionnaires a second time.

“We found that teenagers that participated in the mindfulness group had lower scores in depression after our eight sessions. Girls from the mindfulness group reported sleeping better. We also noticed that they developed mindfulness skills to a greater extent than boys during the sessions,” explained Catherine Malboeuf-Hurtubise from University of Montreal.
