Omega-3 Benefits Dry Age-Related Macular Degeneration

High-dose supplementation with omega-3 EPA and DHA improves vision in people with dry age-related macular degeneration (AMD), according to a recent study published in the journal PharmaNutrition. The high-dose omega-3 supplement consisted of 3.4 grams of EPA (eicosapentaenoic acid) and 1.6 grams of DHA (docosahexaenoic acid) and was taken daily for six months. Age-related macular degeneration is the most common…

Omega-3 Linked to Sleep Quality in Children

In a new study by the researchers from Oxford University, data from the DOLAB research project showed that low blood omega-3 levels—particularly DHA (docosahexaenoic acid)—were associated with decreased sleep quality and an increased risk of sleep disorders in children. Upon further study, the researchers found that supplementation with DHA increased sleep quality. “We have got far less waking during the…

Omega-3 Supplementation and Aging

With the brain benefits of omega-3 fatty acids ever increasing, studies of the effects of omega-3s in older people continue to emerge. In a recent study published in the journal Nutrition, people over the age of 65 with higher blood levels of DHA (docosahexaenoic acid) also exhibited slower cellular aging, as marked by a reduction in the shortening of telomeres,…

Children Not Getting Enough Omega-3

The ratio of omega-6 to omega-3 in the Standard American Diet (SAD) is anywhere from 10:1 to 20:1. That means consumption of omega-6 fats is 10 to 20 times more than omega-3 fats in the SAD diet. This ratio should more like 2:1 to 4:1 in order to maintain healthy omega-3 levels. We’re simply eating far too many omega-6 fats…

Omega-3 Intake May Reduce Oxidative Stress that Leads to Dementia

Mild cognitive impairment (MCI) is a precursor to dementia, and can involve impaired memory, language, thinking, and judgment. One potential contributing factor to MCI is oxidative stress, so a recent study published in the Journal of Nutritional Biochemistry sought to determine whether there is a link between omega-3 EPA and DHA intake and a marker of oxidative stress in the…

Prenatal DHA Linked to Decreased Premature Birth and Low Birth Weight

The omega-3 fatty acid DHA (docosahexaenoic acid) is most concentrated in the brain. This nutrient is well known to be important for brain development of infants. DHA is most rapidly accumulated in the brain during pregnancy, which is why prenatal DHA intake is widely recommended. Despite these recommendations, however, American women are not getting enough. “US women typically consume less…

High Omega-3 Levels Linked to Lower Risk of Death

When it comes to the benefits of a food or nutrient (or even a drug), one of the best indications of efficacy is a reduced risk of death. This makes sense, of course—if a food or nutrient helps us live longer, that’s a good thing. A recent study published in the Annals of Internal Medicine investigated the connection between increased…

Immune Benefits of Omega-3 Fats

The immune benefits of omega-3 fats are generally described as their ability to quell inflammation by balancing the omega-3/omega-6 ratio. Omega-3 fats have an anti-inflammatory effect, and an excess amount of omega-6 fats have an inflammatory effect. Mistaken conclusions have been drawn about the anti-inflammatory effects of omega-3s being immune-suppressive. Dr. Smith has previously helped to explain that immune function…
