These-fatty acids do not protect the brain against cognitive decline, according to scientists
Omega-3 pills do not prevent cognitive decline, according to a study - Reproduction
Supplements based on fish oil rich in omega 3 fatty acids do not protect the brain against mental decline or dementia activity, according to a study of four thousand elderly.
The clinical study for five years and published on Tuesday in the "Journal of the American Medical Association", is "one of the largest ever made in the area," according to the National Institute of American Health, which funded the research. According to the scientists who conducted the study, it found no benefit in Omega-3 to stop the cognitive decline.
The Omega-3-fatty acids are found in fish oils, and people who consume regularly fish like salmon, tuna and halibut showed better eye, heart and brain health compared to those who did not consume these foods. However, consume the oil in pill form is not the same thing. A study in 2011 showed that Omega-3 supplements did not improve brain health of elderly patients with pre-existing heart disease.
The study was done with people with shared vision loss, called age-related macular degeneration (AMD). Patients had an average of 72 years and 58% of them were women.
Volunteers were randomly selected and asked to take either a placebo or capsules with Omega-3-fatty acids, especially docosahexaenoic acid and eicosapentaenoic acid the. Participants underwent cognitive tests and memory at the beginning of the study and then again two and four years later.
"The cognitive levels of each group declined similarly over time, indicating that no combination of nutritional supplements made a difference," said the study.
Approximately 47 million people worldwide suffer from dementia, a number expected to reach 131.5 million in 2050, according to the International Institute for Alzheimer's.
