Omega-3 and healthier brains
by Newsletter Editor
Small declines in memory and thinking can be a sign of dementia, which is linked to oxidative stress. In this study, doctors estimated omega-3s in the diets of 67 older adults with mild cognitive impairment and in 134 healthy elders.
Those with cognitive impairment had much higher levels of lipid hydroperoxides, a sign of oxidative stress, than did healthy participants. Within the group with cognitive impairment, signs of oxidative stress decreased as levels of the omega-3s EPA and DHA increased.
