Omega fatty acids can help protect women from Alzheimer’s disease, revealing why more women are diagnosed, according to a King’s College London study and Queen Mary of London University.
The investigation, published in Alzheimer & Dementia: The Journal of the Alzheimer’s Association, They discovered that women with Alzheimer’s disease had less unsaturated fats, especially healthy such as Omega fatty acids, compared to women without Alzheimer’s.
The researchers analyzed cerebral inflammation and damage to plasma samples of 841 patients with Alzheimer’s disease, according to a press release.

Using mass spectrometry, the researchers classified 700 groups of lipid molecules found in the blood.
“Saturated lipids are generally considered as ‘unhealthy’ or ‘bad’ lipids, while unsaturated lipids, which sometimes contain omega fatty acids, are generally considered ‘healthy’,” said scientists in liberation.

They found a strong increase in lipids with “unhealthy” saturated lipids in patients with female Alzheimer’s.
“Lipids with united Omega fatty acids were the most diminished in the Alzheimer’s group,” the study said.
The study demonstrates a link between Alzheimer’s disease and fatty acids, although more research and clinical trials are needed to confirm the link.

The first author of the study, Dr. Asger Wretlind of the School of Cancer and Pharmaceutical Sciences, said that scientists have been aware that Alzheimer’s disease is more common in women.
“Although this still guarantees additional investigation, we were able to detect biological differences in lipids between the sexes in a great cohort, and show the importance of lipids that contain omegas in the blood, which has not been done before,” Wretlind said in the statement.

He added: “The results are very striking, and now we are seeing how this change occurs early in life.”
According to the centers for disease control and prevention (CDC), about two thirds of the 7 million Americans who have Alzheimer’s disease are women.
Around 4.2 million women 65 years or older have the disease.

“Our study suggests that women should ensure that they are obtaining omega fatty acids in their diet, through fatty fish or through supplements,” said Dr. Cristina Legido-Quigley, reader in systems medicine, at launch.
Omega-3 fatty acids support brain health and can be found in fish such as salmon, chia and linen seeds, nuts and supplements, according to CDC.

While the study suggested that women with Alzheimer have lower levels of some unsaturated fats compared to men, more research is needed, according to Dr. Julia Dudley, Chief of Research of Alzheimer’s Research UK.
“This includes understanding the mechanisms behind this difference and discovering if the changes in the lifestyle, including the diet could have a role,” Dudley said.
He added that understanding how Alzheimer’s works in women instead of men could help doctors to be more specific with future health treatments and advice.

“Understanding how the disease works differently in women could help doctors to adapt future treatments and health councils. Alzheimer’s Research UK is proud to finance this work that will bring us closer to a cure.”
