Low Omega 3 levels ages your brain faster.

We’ve said it before but there’s no harm in saying it again. There is a growing body of evidence linking increased intake of Omega 3 fatty acids, which are primarily DHA and EPA, to better brain health. Once again more evidence emerges.

For instance we’ve talked about the link between Omega 3 fats, commonly found in fish oil, and memory loss.

And we’ve talked about the effect of Omega 3 on your mood, cognitive ability, psychological problems such as depression, a reduced risk of dementia and even in helping reduce alcohol cravings.

Again, at the end of February 2012, more evidence emerges supporting the conclusion that low levels of the Omega 3 essential fatty acids DHA and EPA can have a negative effect on your brain health.

In a new study researchers examined 1575 people with an average age of 67 who were free of dementia, and in particular analysed the levels of DHA and EPA in their blood.Omega 3 and brain health

The subjects were given a range of tests to measure brain function and memory, including brain imaging and psychological assessments.

What was discovered was that participants in the study who had the lowest levels of Omega 3 had smaller brain volumes and a poorer cognitive performance. They performed poorer on tests measuring memory and thinking, and worse than those who exhibited a higher levels of Omega 3 in the blood.

In effect what they have found is that people with lower levels of Omega 3 in the blood seem to have a faster rate of brain ageing which translates into poorer cognitive performance and memory.

The specific conclusion of the study was that “Lower RBC DHA levels are associated with smaller brain volumes and a “vascular” pattern of cognitive impairment even in persons free of clinical dementia.”

The evidence mounts up of a link between Omega 3 and brain health, or conversely between low levels of Omega 3 intake and poorer brain health.

What is not entirely clear is how long you need to increase your Omega 3 intake before there is some positive effect on your brain health, and of course this is an important factor. The study did not examine this.

However whether or not you’re concerned about improving your brain health there are so many other powerful reasons for including more Omega 3 fatty acids in your diet. Improved brain health may simply be one of them, there are so many others.

Whether you want to reduce your risk of macular degeneration as you get older, reduce your risk of dying from heart attack, help improve your likely outcome from arthritis treatment, help reduce symptoms of depression, improve your skin or have a better outcome in any one of a wide range of health conditions, (which you can see listed on the right for your reading) it seems there are powerful reasons to increase the amount of Omega 3 fatty acids in your diet.

Of course you can do so by eating more fish, though more people choose simply to take Omega 3 supplements for a number of reasons. And if you want you can find out more about how we have determined which Omega 3 supplements to take for ourselves in our article about finding the best Omega 3 supplements.
