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

Friday, February 21, 2014

Most people take a healthy immune response for granted, as it typically remains on guard detecting a host of known and as yet unidentified pathogens that may threaten our health. Bacteria and viruses that cause the common cold, flu, digestive distress and a variety of potentially fatal illnesses are identified and destroyed before they cause more than a minor discomfort. For most of the past decade, fish consumption and supplementing with DHA and EPA fortified supplements has been shown to lower levels of systemic inflammation and significantly reduce the risk of developing many cancers, stroke and cardiovascular disease, yet the precise mechanism of action has been unknown.

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.

Should men keep consuming fish or fish oil supplements

Sunday, January 19, 2014


(Women of course should keep on consuming fish or fish oil supplements. In addition to all the benefits listed below:

Regular use of fish oil supplements, which contain high levels of the omega-3 fatty acids, EPA and DHA, was linked with a 32 percent reduced risk of breast cancer.

In the first population-based study in women of childbearing age, those who rarely or never ate fish had 50 percent more cardiovascular problems over eight years than those who ate fish regularly. Compared to women who ate fish high in omega-3 weekly, the risk was 90 percent higher for those who rarely or never ate fish.)


The report about the Omega-3 very strong connection to prostate cancer is very disturbing, although personally, that risk is in the past. Nevertheless, for almost all males, a risk-reward calculation should be made of the risk vs.the benefits of Omega-3 consumption. Because, while the risks are great, so are the rewards.

Heres what I wrote in 2008:

Jons Health Tips: Eating Fish

I eat a lot of fish – mostly salmon, but lots of other fish as well. However, I avoid swordfish and tuna, especially tuna steaks and albacore because of high levels of mercury, and tilapia because of high levels of omega-6. I eat fish because its healthy and I like it, and when I’m eating fish I’m not eating meat. I supplement my fish consumption with fish oil or flaxseed oil on days that I do eat meat.

My daughter, who is a pediatrician and vegetarian, also uses flaxseed oil and gives her 3 children fish oil supplements.

Here’s why: (see link above for details on each of these)

Fish reduces asthma and allergies

Eating fish may explain very low levels of heart disease in Japan

Eating Fish May Prevent Memory Loss and Stroke

A diet rich in fish and omega-3 oils, may lower your risk of dementia and Alzheimer’s disease, according to a study published in the November 13, 2007, issue of Neurology®, the medical journal of the American Academy of Neurology. People who ate fish at least once a week had a 35-percent lower risk of Alzheimer’s disease and 40-percent lower risk of dementia.

Oily fish can protect against rheumatoid arthritis

Eating fish and foods with omega-3 fatty acids linked to lower risk of age-related eye disease

The evidence of health benefits has grown even stronger since then. Here is a small sampling:


1. There is mounting evidence that omega-3 fatty acids from fish or fish oil supplements not only help prevent cardiovascular diseases in healthy individuals, but also reduce the incidence of cardiac events and mortality in patients with existing heart disease. A new study, published in the August 11, 2009, issue of the Journal of the American College of Cardiology, extensively reviews data from a broad range of studies in tens of thousands of patients and sets forth suggested daily targets for omega-3 consumption.

2. Omega-3 Fatty Acids=Reduced Risk of Colon Cancer

3. Omega-3 fatty acid kills neuroblastoma cancer cells

4. New research has shown for the first time that omega-3 in fish oil could "substantially and significantly" reduce the signs and symptoms of osteoarthritis.

5. Eating at least two servings of oily fish a week is moderately but significantly associated with a reduced risk of stroke, finds a study published on bmj.com today. But taking fish oil supplements doesnt seem to have the same effect, say the researchers.

And most important:

6. Older adults who have higher levels of blood omega-3 levels—fatty acids found almost exclusively in fatty fish and seafood—may be able to lower their overall mortality risk by as much as 27% and their mortality risk from heart disease by about 35%, according to a new study from Harvard School of Public Health (HSPH) and the University of Washington. Researchers found that older adults who had the highest blood levels of the fatty acids found in fish lived, on average, 2.2 years longer than those with lower levels.
