According to a new study published in Neurology, omega-3 fatty acids may improve brain structure and cognition in middle-aged adults. The study, which was conducted by researchers at the University of Bristol in the United Kingdom, looked at data from over 4,000 adults aged 40-79 who participated in the UK Biobank study.
After controlling for other factors that could affect brain structure and cognition, the researchers found that those who had higher levels of omega-3 fatty acids in their blood were more likely to have better cognitive function and brain structure. In particular, they found that omega-3s were associated with higher grey matter volume in the brain, as well as better performance on tests of working memory, perceptual speed, and Verbal Fluency.
Interestingly, the benefits of omega-3s were most pronounced in those who were not obese, suggesting that the fatty acids may be particularly beneficial for preventing age-related cognitive decline in healthy adults.
While the findings are preliminary and more research is needed to confirm the link between omega-3s and brain health, the study provides strong evidence that omega-3 fatty acids could play a role in preserving cognitive function in middle-aged adults. Given the growing body of evidence showing the benefits of omega-3s for brain health, it may be worth considering incorporating more omega-3-rich foods into your diet, such as fatty fish, flaxseeds, and chia seeds.
According to a new study, eating foods rich in omega-3 fatty acids may be associated with better brain structure and cognition in middle-aged adults.
Omega-3 fatty acids are found in fish, plant oils, and nuts. They have a variety of health benefits, including reducing inflammation and lowering blood pressure.
Previous research has linked omega-3s to better cognitive function in older adults. However, it is not clear if these benefits extend to middle-aged adults.
The new study, published in the journal Neurology, included 1,111 adults aged 55-80. The participants were asked to complete a food frequency questionnaire and underwent brain scans.
The findings showed that those who had higher levels of omega-3 fatty acids in their blood had better brain structure and cognition.
The study did not prove that omega-3s directly improve brain health, but the results suggest that these fats may have a protective effect.
Eating fish or taking omega-3 supplements may be a good way to increase your intake of these beneficial fats.
