A new study published in the journal Neurology suggests that omega-3 fatty acids may protect against cognitive decline in midlife. The study, which was conducted by researchers at Brigham and Women's Hospital in Boston, Massachusetts, looked at data from over 10,000 people who were part of the Framingham Heart Study. The participants were followed for an average of 20 years, and their cognitive function was assessed at multiple points during that time.
The researchers found that people with higher levels of omega-3 fatty acids in their blood were less likely to experience cognitive decline over time. This was true even after taking into account other factors that could affect cognitive function, such as age, sex, education, and smoking status. In the study, they used the Omega-3 Index (O3I) test to measure the level of omega-3 in the blood, and lucky for you, Dr. Bill Harris (inventor of the O3I) is a good friend of ours at Premier Catch, and YOU can measure your own O3I using this super easy omega-3 blood test kit.
The researchers believe that omega-3 fatty acids may protect against cognitive decline by reducing inflammation in the brain. Inflammation is a known risk factor for Alzheimer's disease and other forms of dementia.
In addition to the benefits for cognitive health, omega-3 fatty acids have also been shown to have a number of other health benefits, including reducing the risk of heart disease, stroke, and cancer. To increase your intake of omega-3 fatty acids you can eat foods that are naturally high in omega-3 fatty acids, such as wild fish, and nuts and seeds. You can also take omega-3 supplements. (It’s important to talk to your doctor before taking any supplements, as they may interact with other medications you are taking.)
We all want to stay sharp and witty as we age, and there are a number of things we can do to protect our cognitive health beyond eating wild fish consistently, including eating a healthy balanced diet, exercising regularly, and getting enough sleep!
