Eating more fish could reduce postpartum depression

Emerging evidence suggests many pregnant women are deficient in omega-3
Low levels of omega-3 may be behind postpartum depression, according to a review lead by Gabriel Shapiro of the University of Montreal and the Research Centre at the Sainte-Justine Mother and Child Hospital. Women are at the highest risk of depression during their childbearing years, and the birth of a child may trigger a depressive episode in vulnerable women. Postpartum depression is associated with diminished maternal health as well as developmental and health problems for her child. "The literature shows that there could be a link between pregnancy, omega-3 and the chemical reaction that enables serotonin, a mood regulator, to be released into our brains," Shapiro said. "Many women could bring their omega-3 intake to recommended levels." The findings were announced by the Canadian Journal of Psychiatry on November 15, 2012.
Because omega-3 is transferred from the mother to her fetus and later to her breastfeeding infant, maternal omega-3 levels decrease during pregnancy, and remain lowered for at least six-weeks following the birth. Furthermore, in addition to the specific biological circumstances of pregnant women, it has been found in the US that most people do not consume sufficient amounts of omega-3. "These findings suggest that new screening strategies and prevention practices may be useful," Shapiro said, noting that the study was preliminary and the further research would be needed to clarify the link and identify the reasons for it.
Fish oil supplements may protect the heart in stressful situations
Monday, March 10, 2014
Fish oil supplements may protect the heart in stressful situations, according to a recent study. Jason Carter, a researcher at Michigan Technological University, conducted the study with 67 healthy volunteer test participants in their 20s. Over a 2-month period, they were either given nine grams of fish oil pills or nine grams of olive oil as a placebo.
The test subjects were screened for heart rate, blood pressure and other related metrics. At the end of the test period, both groups took a mental arithmetic test that involved adding and subtracting numbers in their head. Their stress response was measured at that time.
“Those in the fish oil group showed blunted heart rate reactivity while they were stressed compared to those who took olive oil," said Carter. "Similarly, the total [muscle sympathetic nerve activity] reactivity to mental stress was also blunted in the fish oil group.” There was not much difference between the two groups at rest, however.
Results of the study were published in the May edition of the American Journal of Physiology – Regulatory, Integrative, and Comparative Physiology, published by the American Physiological Society. It is available online at http://bit.ly/10j0CSS
Omega 3 Fats Found in Fish Oil Boost Immune Response to Help Fight Inflammation and Disease

Fish Oil Fats, DHA and EPA Stimulate Immune System B cells to Fight Inflammation and Disease Risk
A group of researchers from the Department of Food Science and Human Nutrition at Michigan State University have published the result of their work in the Journal of Leukocyte Biology that shows how DHA-rich fish oil enhances B cell activity, a white blood cell that is critical to activate our immune response. One of the study authors, Dr. Jennifer Fenton explained “Fish oil may have immune enhancing properties that could benefit immunocompromised individuals.”
Omega-3 fat sources including fish oil include the long chain fatty acids, DHA and EPA that have been shown in a number of prior studies to reduce total body inflammation that help to lower the risk of developing many chronic illnesses including cancer, heart disease, dementia and stroke. Researchers now uncover how these special fats enhance B-cell activity, a white blood component necessary to improve immune system activity and lower inflammatory response.
Supplement Daily with A Distilled Fish Oil Capsule to Squelch Inflammation and Lower Disease Risk
Researchers used two mouse models to conduct their study, one group was fed a control diet and the other was fed a diet supplemented with DHA-rich fish oil for a period of five weeks. B cells were taken from various tissues and the scientists then looked for markers of B cell activation on the cell surface, B cell membrane changes, and B cell cytokine production to assess immune response activation.
The team found that those mice supplemented with DHA-enriched fish oil demonstrated B cell activation and antibody production to aid immune response and pathogen clearance, while damping systemic inflammation. The authors concluded “This work confirms similar findings on fish oil and B cells… and moves us one step closer to understanding the immune enhancing properties of EPA and DHA.” Adults should supplement with a distilled fish oil preparation (1,200 to 2,400 mg EPA/DHA per day) to fight inflammation and heighten immune system response.
