New research shows that healthy young people who consumed more omega-3 fats showed a marked reduction both in inflammation and anxiety. Omega-3′s such as EPA and DHA have long been considered positive additives to the diet.
According to Eurekalert:
“[P]sychological surveys clearly showed an important change in anxiety among the students: Those receiving the omega-3 showed a 20 percent reduction in anxiety compared to the placebo group.”
The omega-3 fats EPA and DHA play an important role in your emotional well-being. The Brain Behavior and Immunity study showed a dramatic 20 percent reduction in anxiety among med students taking omega-3, while past research has shown omega-3 fats such as those found in krill oil work just as well as antidepressants in preventing the signs of depression, but without any of the side effects. Low plasma concentrations of DHA is associated with low concentrations of brain serotonin, which may be associated with depression and suicide.
In fact, inadequate intake of omega-3 fats is known to change the levels and functioning of both serotonin and dopamine (which plays a role in feelings of pleasure), as well as compromise the blood-brain barrier, which normally protects your brain from unwanted matter gaining access. Omega-3 deficiency can also decrease normal blood flow to your brain, an interesting finding given that studies show people with depression have compromised blood flow to a number of brain regions.
Finally, omega-3 deficiency also causes a 35 percent reduction in brain phosphatidylserine (PS) levels, which is relevant considering that PS has documented antidepressant activity in humans. Interestingly, omega-3 fats have even been known to help reduce violent behavior and aggression, and even improve the ability to concentrate in people with ADHD, so the impact on your brain health is quite significant.
