People with lower EPA and DHA in red blood cell membranes, which correlates to lower scores on the Omega-3 index, were found to have an increased risk of cardiovascular disease and ultimately a decrease in lifespan compared to those who scored higher on the omega-3 index.
Commonly associated with helping improve brain function, the omega 3 fatty acid DHA may have another, previously unknown benefit. A new study reports DHA and other related fatty acids may help slow the development of cancerous tumors.
At age ten, children whose mothers took fish oil supplements during pregnancy were more efficient at problem-solving tasks and had better attentional focus than those whose mothers just took folic acid or no supplements at all.
Adolescents with higher levels of Omega 3 fatty acids in their blood had a decreased risk of developing psychosis as they entered into early adulthood. At the age of 24, those with psychosis had lower levels of DHA than those without the disorder.
DHA supplements have long been recommended for pregnant women to assist in healthy fetal development. A new study finds DHA supplements can also reverse the impact of early prenatal stress on developing male babies.
DHA may be more effective at reducing chronic inflammation than EPA.
DHA treatment reduced the size of the damaged brain area and initiated a repair mechanism in animal models of stroke. DHA affected the levels of MANF and TREM2, two proteins critical for communication between brain cells.
The gene Elovl2 appears to play a significant role in age-associated functional and anatomical aging in mouse retinas. The finding has direct implications for age-related eye diseases, such as macular degeneration. When the expression of the gene was boosted, age-related visual function improved.
Adding a lysophospholipid form of EPA, LPC-EPA, to the diet increased omega 3 fatty acid levels up to 100 fold in the brains of mice, researchers report. The amount required for the boost in Omega 3 levels is less than a milligram a day. In humans, researchers report, the equivalent is less than a quarter of a gram of LPC-EPA per day to have the same effect.
Contrary to previous findings, researchers report Omega 3 fatty acids do not help improve reading, learning and memory skills in school aged children.
