The Omega-3 index records the percentage concentration of omega-3 in red blood cells, and provides a good indication of a person’s long-term intake of omega-3s. A recent study suggests that teenagers with a higher Omega-3 index have better information processing speeds when compared with those with a lower Omega-3 index.

Participants in the study included 266 Dutch teens between the ages of 13 and 15. The researchers took blood samples from all of the teens and also assessed cognitive performance via a range of tests.

The participants filled out a fish consumption questionnaire, and it showed that 13.9% of the teens did not consume any fish at all and that 77% of them consumed fish rarely. As a result, the average Omega-3 Index was 3.83%, which was much lower than the recommended 8%-11%.

After examining the data, the researchers found that a higher Omega-3 Index was associated with higher scores on the Letter Digit Substitution Test. Specifically, every 1% increase in the Omega-3 Index was associated with a 1.23 digit increase. They also noted that the students with a higher Omega-3 Index had “fewer errors of omission” on the D2 test of attention, which means that they paid better attention than students with a lower Omega-3 Index.

Researchers from the Open University of the Netherlands, Omegametrix (Germany), Aker BioMarine (Norway), and Maastricht University (The Netherlands) conducted the study. It was published on January 2, 2016, in Nutrients.

Omega-3s have been linked to a number of health benefits, including better moods, improved joint mobility, helping with age related macular degeneration, and aiding your immune system.

Because omega-3 fatty-acids are not found naturally in the human body, it is especially important to make sure that they are a part of your daily diet. Oily, dark fish such as tuna and salmon are high in omega-3s. For vegans like the ones in this study or for folks who just don’t like fish, consider taking a daily high quality non-fish supplement that has been tested for purity and potency.

The omega-3 index is a measure of the fatty acid status of a person. A recent study suggests that a higher omega-3 index may be associated with lower triglyceride levels.

Participants in the study included 276 people with a mean age of 77.6 who took part in the Retirement Health and Lifestyle Study. Participants with the highest omega-3 index had up to 28% lower triglyceride levels than people with the lowest omega-3 index. Participants with the highest index also had a better ratio of total cholesterol to HDL cholesterol.

The researchers noted differences between men and women, including the fact that only the women with the lowest omega-3 index had elevated triglyceride levels.  Additionally, the women in general had significantly higher omega-3 indexes than the men.

Researchers from the University of Newcastle conducted the study. It was published in the January 2016 issue of The Journal of Nutritional Biochemistry.

The research regarding the effect of omega-3s on depression has been unclear, however the majority of it has focused on people who consume Western diets with lower fish intake. A recent study suggests that omega-3s may help lower depressive symptoms even in countries with higher fish consumption.

Participants in the study included 1,050 Japanese men and 1,073 Japanese women with an average age of 60. All of the participants were instructed to fast for at least 12 hours. Blood was collected in the early hours of the morning following the fasting. The researchers used the Centre for Epidemiologic Studies Depression Scale to determine that 266 or 12.5% of the study population had depressive symptoms. Those participants were also significantly more likely to be unmarried, have fewer years of educations, and a higher risk of past stroke when compared with those without depressive symptoms.

The researchers found that that blood concentration of omega-3 was inversely associated with depressive symptoms. Additionally, the researchers noted significant differences in EPA, omega-3 PUFA, and omega-3 long chain PUFA between people with depressive symptoms and those without depressive symptoms. The average omega-3 long chain PUFA concentration of people with depressive symptoms was 264.1 microgram per ml, while the average concentration of people without depressive symptoms was 276.0 microgram per ml.

No association was found between depressive symptoms and omega-6 levels.

Researchers from the Japanese National Centre for Geriatrics and Gerontology, the Aichi Shukutoku University, and the Nagoya University of Arts and Sciences in Japan, as well as Suntory Wellness Limited conducted the study. It was published online ahead of print on December 22, 2015 in the British Journal of Nutrition.

Omega-3s have been linked to a number of health benefits, including alleviating arthritis pain, better moods, improved joint mobility, helping with age related macular degeneration, and aiding your immune system.

People With Higher Omega-3 Levels May Live Longer

Filed under: Omega-3 — Sarah @ 9:00 am

Americans tend to have low omega-3s fatty acid levels. According to the Global Organization for EPA and DHA Omega-3s, only 50% of men and 40% of women get the recommended daily amount. That could be bad news for mature adults, as a recent study suggests that people with higher levels of polyunsaturated fatty acids live longer than those with lower levels.

Participants in the study included 2,193 Swedish women and 2,039 Swedish men. The researchers tested their blood for levels of different fats when they were 60 and then followed them for a minimum of 14.5 years. During that time, 484 cardiovascular disease events and 456 all-cause deaths were recorded in people with no prior cardiovascular disease.

The researchers found that higher levels of EPA and DHA fatty acids were associated with lower risks of cardiovascular disease in women, while ALA was associated with moderately increased risk. They also noted an inverse association between EPA and DHA levels and all-cause mortality in all of the participants. Finally, they noted a decreased risk in all-cause mortality in men associated with LA levels.

Researchers from Uppsala University in Sweden conducted the study. It was published online ahead of print on June 17, 2015, in the American Heart Association’s journal Circulation.

Omega-3s have been linked to a number of health benefits, including alleviating arthritis pain, better moods, improved joint mobility, helping with age related macular degeneration, and aiding your immune system.

Oily, dark fish such as tuna and salmon are high in DHA and EPA omega-3s. T If you don’t like the taste of fish or are just finding it hard to work it into your meal plans, consider taking a high quality supplement. Make sure your supplement is tested for purity and potency.

People With Bipolar Disorder May Have Lower Levels of Omega-3’s

Filed under: Omega-3 — Sarah @ 9:00 am

Omega-3s are an essential part of cell-to-cell communication in the brain and have also been found to combat inflammation, which previous studies suggest may contribute to depression. A recent study further examined how omega-3s and depression interact and found that people with bipolar disorder may have lower levels of an omega-3 fatty acid that crosses the blood-brain barrier than people without bipolar disorder.

Participants in the study included 27 people with symptomatic bipolar disorder and 31 healthy controls. The researchers measured blood levels of different forms of the polyunsaturated fatty acids omega-3 and omega-6. Additionally, the participants self-reported fatty acid consumption and bipolar medication use.

Free fatty acids can cross the blood-brain barrier but fatty acids that are bound to proteins cannot. The researchers found that the subjects with bipolar disorder had a lower ratio of free-circulating omega-3 fatty acid EPA to protein-bound EPA when compared with people who did not have bipolar disorder. This means that people with bipolar disorder have lower availability of omega-3’s in the body.

The researchers hope that this study will prompt further investigations into omega-3 levels and omega-3 supplementation and depression.

Researchers from Penn State College of Medicine and the National Institutes of Health conducted the study. It was published in the November 2015 issue of the journal Bipolar Disorders.

Omega-3s have been linked to a number of health benefits, including alleviating arthritis pain, better moods, improved joint mobility, helping with age related macular degeneration, and aiding your immune system.

Krill Oil May Help With Post-Exercise Immune Function

Filed under: Omega-3 — Emma @ 9:00 am

Vigorous exercise lowers immunity by decreasing the number of natural killer (NK) cells a person is producing. A recent study suggests that taking krill oil supplements may improve the immune function of healthy, exercising adults by increasing the activity of NK cells as well as increasing the production of IL-2 (which regulates the activity of immune cells) in the recovery period after exercise.

Participants in the study included 37 healthy men and women with an average age of 25.8 who were given two grams of krill oil or a placebo daily for six weeks. All of the participants performed a simulated cycling time trial at the onset and conclusion of the study.

The researchers found that the krill oil supplement was associated with a 75% and 21% increase in erythrocyte EPA and DHA levels, respectively, and a 27% increase in the Omega-3 Index. They also noted decreases in arachidonic and docosatetraenoic acid of 7% and 17%, respectively.

Finally, the researchers noted significant increases in the production of PBMC IL-2 and in NK cell activity in the krill oil group during the recovery period. Other cytokines were not affected.

The researchers did not note any effect on heart rate or oxygen consumption.

Researchers from the University of Glasgow conducted the study. It was published on September 25, 2015, in PLoS One.

Krill oil is rich in omega-3s, which have been linked to improved joint mobility, aiding your immune system, and helping with age-related macular degeneration. Previous studies suggest that krill oil may be superior to fish oil in raising omega-3 levels.

Eating More Fish May Help Reduce the Risk of Depression

Filed under: Omega-3 — Emma @ 9:09 am

Depression affects as many as 350 million people worldwide. A recent study suggests that eating high amounts of fish may help reduce the risk of developing depression.

Researchers examined databases for relevant studies and found 101 articles containing relevant studies. Of those, 16 were eligible for inclusion in their analysis. There were 26 studies included in those 16 articles, for a total of 150,278 participants.

Ten of the studies included were cohort studies, meaning the researchers monitored people who didn’t have depression at the beginning of the study in order to measure how many participants developed it. The other studies were cross-sectional, meaning they examined the association between depression and other variables at a single point in time or over a specific, brief period.

Ten of the studies included participants from Europe, seven were from North America, and the remainder were from Asia, Oceania, and South America.

After examining all of the data, the researchers found a 17% reduction in risk of depression in the participants who ate the most fish when compared with those who ate the least. This finding held true for both cohort and cross-sectional studies.

When the researchers controlled for gender, they found that men had a 20% reduced risk of depression while women had a slightly lower reduced risk of 16%.

The researchers cautioned that no definitive conclusions could be drawn from the data. They did however suggest that the association could be due to the fact that the omega-3 fatty acids found in fish have been shown to alter the microstructure of brain membranes and change the activity of the neurotransmitters dopamine and serotonin. They also suggested that the high quality protein, vitamins, and minerals found in fish may help combat depression or that eating a lot of fish may be associated with a healthier and more nutritious diet in general.

Researchers from Qingdao University in China conducted the study. It was published online ahead of print on September 10, 2015, in the Journal of Epidemiology & Community Health.

More and more research is showing that fish consumption is extremely important to maintaining good health, especially as we age. Many of these studies have linked the positive health benefits of fish to their omega-3 fatty acid content. Omega-3 fatty acids have been associated with benefits ranging from improved heart health, better moods, improved joint mobility, and aiding your immune system.

If you don’t like the taste of fish or are concerned about the mercury levels present in some fish, try adding a high quality supplement to your daily routine. Make sure, however, that your supplement has been tested for potency and purity in order to get the most out investment.

Diagnoses of attention deficit/hyperactivity disorder (ADHD) are on the rise and are often treated with prescription medications. A recent study suggests that taking a daily supplement of DHA and EPA omega-3s may improve attention both in kids with ADHD and in those without.

Participants in the study included 77 boys between the ages of 8 and 14. Half of the boys had diagnoses of ADHD and half did not. The participants were given either 10 grams of margarine containing 650 mg of DHA and EPA or 10 grams of margarine without the supplemental omega-3s daily for sixteen weeks.

At the conclusion of the study, the researchers found that all of the boys who took the omega-3 supplement had improvements in parent-rated attention, as measured by the Child Behavior Checklist (CBCL). However, they did not note any changes in cognitive control or fMRI measures of brain activity in the boys. Finally, they noted higher DHA blood levels in the boys who took the supplemental margarine.

Researchers from the University Medical Center Utrecht conducted the study. It was published online on April 22, 2015, in the journal Neuropsychopharmacology.

Omega-3s have been linked to a number of health benefits, including alleviating arthritis pain, better moods, improved joint mobility, helping with age related macular degeneration, and aiding your immune system.

Omega-3 Supplements May Help Muscle Function and Mass in Older Adults

Filed under: Omega-3 — Sarah @ 9:15 am

As we age, we naturally have a decrease in muscle function and muscle mass, but steps can be taken to combat that. A recent study has found that fish oil-derived omega-3 supplements may improve muscle function and muscle mass in healthy mature adults.

Participants in the study included sixty men and women between the ages of 60 and 85. They were given 3.6 g EPA/DHA of fish oil-derived omega-3s or a placebo in the form of corn oil. They took their pills daily for six months.

In order to assess muscle function and muscle mass, the researchers measured muscle volume, handgrip strength, one-repetition maximum lower and upper body strength, and average power during isokinetic leg exercises at the beginning and the end of the study.

At the conclusion of the study, the researchers noted that body weight, total body fat mass, and inter-muscular fat content was not significantly affected by the omega-3 supplements. However, they did note a significant increase in thigh muscle volume, handgrip strength, and one-repetition muscle strength in the omega-3 group. One-repetition muscle strength is a composite score for leg press, chest press, knee extension, and knee flexion.

The researchers recommended that fish oil-derived omega-3s be included in therapeutic approaches aimed at preventing sarcopenia and helping older adults maintain muscle function and independence.

Researchers from the Center for Human Nutrition at the Washington University School of Medicine in St. Louis, MO, conducted the study. It was published online ahead of print on May 20, 2015, in The American Journal of Clinical Nutrition.

Brain Health Benefits of B Vitamins Shown to Be Dependent on Omega-3 Levels

Filed under: Omega-3,Vitamin B — Sarah @ 9:41 am

Previous studies have shown that B vitamin supplements may support brain health by reducing brain tissue loss, but the results have not always been consistent.  In a new study of individuals with mild cognitive impairment (MCI), those given B vitamin supplements and who already had high blood levels of omega-3 fatty acids experienced a 40% slowdown in brain atrophy. On the other hand, those who had low omega-3s at the outset, did not experience a benefit from B vitamin supplementation.

Participants in the study included 168 people over the age of 70. They were given a placebo or a vitamin B supplement containing 0.8 mg folic acid, 20 mg B6, and 0.5 mg B12 every day for two years.

 

At the conclusion of the study, the researchers found that found that participants with the highest average omega-3 levels at the start of the study — levels higher than 590 micromoles per liter — had a 40% slower rate of brain atrophy when compared with the placebo group. They did not observe any association between the lowest average omega-3 levels, those that were less than 390 micromoles per liter, and brain atrophy.

 

The researchers also found a link between B vitamins, omega-3s, and homocysteine levels. The results of their study showed that a sufficient level of vitamin B and low homocysteine levels are needed for the optimal utilization and distribution of omega-3 fatty acids. Homocysteine is an amino acid that has been linked to suspected or confirmed dementia.

 

The researchers concluded that pre-existing levels of plasma omega-3 fatty acids in the body to be high enough to enable vitamin B to counteract brain atrophy. This would explain why some studies looking at vitamin B and brain health have found no link.

 

Researchers from the University of Oxford and other universities conducted the study. It was published in the July 2015 issue of the American Journal of Clinical Nutrition.

 

B vitamins have been linked to numerous health benefits, including improving breast health, nervous system function, red blood cell formation, and hormone function. Studies have also suggested that B vitamins may reduce the risk of hearing loss, and birth defects

 

Our bodies do not naturally synthesize B vitamins. However, it is easy to increase your intake by eating more folate- rich foods. Some foods rich in folate include liver, eggs, beans, sunflower seeds, asparagus, leafy green vegetables, oranges, strawberries, cantaloupes, and other melons. B  vitamin intake also can be bolstered through supplements or fortified foods.

 

Omega-3s have also been linked to a number of health benefits, including improving joint health, heart health and eye health and boosting moods and immune system function.

 

Like B vitamins, omega-3s are not found naturally in the human body, so it is especially important to make sure that they are a part of your daily diet. Oily, dark fish such as tuna and salmon are high in DHA and EPA omega-3s. T If you dont like the taste of fish or are just finding it hard to work it into your meal plans, consider taking a high quality supplement. Make sure your supplement is tested for purity and potency.
