Are Omega-3s Good for Your Brain?

Omega-3 is easily the most popular supplement in America. Roughly 8% of adults—or about 19 million people—take some kind of omega-3 fatty acid supplement, according to the latest figures from the National Institutes of Health. There’s a reason fish oil capsules and other omega-3 supplements are so popular. “Omega-3 fatty acids are involved in many different fundamental [brain] processes,” says Simon Dyall, a principal academic and head of nutrition at Bournemouth University in the UK. Omega-3 polyunsaturated fatty acids—namely EPA and DHA—and their metabolites influence gene expression, oxidative stress, cerebral blood flow, levels of neurotransmitters, and other brain-related processes such as the production of new neurons, Dyall explains. DHA in particular is an essential building block of the brain’s cell membranes. So at a molecular level—like a house without bricks or walls—the brain could not exist without omega-3 fatty acids. What’s not clear today is whether swallowing a fish oil pill or some other type of omega-3 supplement can improve cognitive function or safeguard brain health. “We have a lot of evidence that omega-3’s may have favorable effects on the brain, but the evidence on dietary intakes and supplements is inconclusive,” says Aron Barbey, an associate professor and director of the Center for Brain Plasticity at the University of Illinois at Urbana-Champagne. Barbey’s...

Abstract Longer lifespan is accompanied by a larger number of chronic diseases among older adults. Because of a growing proportion of older adults in the U.S., this brings the problem of age-related morbidity to the forefront as a major contributor to rising medical expenditures. We evaluated 15-year time trends (from 1998 to 2013) in the prevalence of 48 acute and chronic non-cancer diseases and cancers in older U.S. adults aged 65+ and estimated the annual percentage changes of these prevalence trends using SEER-Medicare and HRS-Medicare data. We found that age-adjusted prevalence of cancers of kidney, pancreas,...

This study builds on preliminary findings from the first phase of the INTERSTROKE study, which identified ten modifiable risk factors for stroke in 6,000 participants from 22 countries. The full-scale INTERSTROKE study included an additional 20,000 individuals from 32 countries in Europe, Asia, America, Africa and Australia, and sought to identify the main causes of stroke in diverse populations, young and old, men and women, and within subtypes of stroke. To estimate the proportion of strokes caused by specific risk factors, the investigators calculated the population attributable risk for each factor (PAR; an esti...

Conclusion This study found people taking PPIs had a 44% higher risk of developing dementia in a seven-year period compared with those not taking the drugs. However, it's not accurate to say this was down to the PPIs – the study couldn't prove this, and there are many possible explanations. For a start, the groups weren't very similar. Those taking PPIs had poorer health, and were more likely to be taking a number of medicines and have conditions linked to a higher risk of dementia, such as diabetes and heart disease. After taking these factors into account in the analysis, the link between...

In this study, researchers wanted to see why this is and if there could be any human applications.Researchers collected white blood cells from African and Asian elephants. They found that elephants have at least 20 copies of a gene called TP53. TP53 is known to encourage cell "suicide" when DNA is damaged, stopping any potential cancer in its tracks. In contrast, humans are thought to have only a single copy of the TP53 gene.Of course the big question – the elephant in the room, if you will – is how we can boost TP53 activity in humans to stimulate a similar protective effect. The simple answer is: we...
