Fish Oil Supplements Linked To Improved Brain Health
A recent study has found fish oil benefits on brain and aging. Taking fish oil supplements, can help you not only slow down aging but keep your brain healthy longer. Now, what might be new is that fish oil does seem to positively impact the physical structure of the brain. The study found that fish oil supplements use can help slow down brain shrinkage.
The study was led by Lori Daiello, PharmD, a research scientist at the Rhode Island Hospital Alzheimer's Disease and Memory Disorders Center. Data for the analyses was obtained from the Alzheimer's Disease Neuroimaging Initiative (ADNI), a large multi-center, NIH-funded study that followed older adults with normal cognition, mild cognitive impairment, and Alzheimer's Disease for over three years with periodic memory testing and brain MRIs.
The study included 819 individuals, 117 of whom reported regular use of fish oil supplements before entry and during study follow-up. The researchers compared cognitive functioning and brain atrophy for patients who reported routinely using these supplements to those who were not using fish oil supplements.
Daiello reports that compared to non-users, use of fish oil supplements was associated with better cognitive functioning during the study. However, this association was significant only in those individuals who had a normal baseline cognitive function and in individuals who tested negative for a genetic risk factor for Alzheimer's Disease known as APOE4. This is consistent with previous research.
The unique finding, however, is that there was a clear association between fish oil supplements and brain volume. Consistent with the cognitive outcomes, these observations were significant only for those who were APOE4 negative.
Daiello says, "In the imaging analyses for the entire study population, we found a significant positive association between fish oil supplement use and average brain volumes in two critical areas utilized in memory and thinking (cerebral cortex and hippocampus), as well as smaller brain ventricular volumes compared to non-users at any given time in the study. In other words, fish oil use was associated with less brain shrinkage in patients taking these supplements during the ADNI study compared to those who didn't report using them." See original story
If you ask me, it is better to have no teeth but still keep a healthy and active brain, with less or shrinkage, for as long as possible. At least you can get artificial functional teeth, but they are yet to make an artificial functional brain. One more reason to pop that fish oil pill.
