Omega-3s for Alzheimer's Disease Prevention

I had to post this. Remember the video I previously posted of some dude having fun with Photo Booth (click HERE for that post)? Well, my oldest son thought it was pretty funny too, and he took it upon himself to do something similar. This was at least a few weeks ago now, but I'm just getting around to putting it online.

This was totally spontaneous, no practicing, and we didn't even know what he was doing--until we saw this...

Ok, now let's talk about this new study. Previous research has shown that diet could play an important role in preventing or delaying the onset of Alzheimer disease and other forms of age-related dementia.

This new study suggests consumption of foods containing high levels of omega-3 fatty acids may be associated with lower blood levels of the protein called beta-amyloid , which has been implicated in the onset of Alzheimer's disease and memory problems.

The researchers revealed that an additional one gram of omega-3 per day--over and above the average omega-3 consumed by people in the study--was associated with 20 - 30% lower blood beta-amyloid levels.

This suggests that the potential beneficial effects of omega-3 fatty acids intake on Alzheimer’s disease and cognitive function in the literature might be at least partly explained by a beta-amyloid-related mechanism.” The next step would be to determine if blood/plasma beta-amyloid proteins reflect the levels in the brain (which is harder to measure).

The data comes from 1,219 people aged over 65 in a cross-sectional study that aimed to to examine the association between dietary intake of nutrients and plasma levels of beta-amyloid. All participants were free of dementia and provided information about their diet for an average of 1.2 years before blood was tested for beta-amyloid levels.
