Omega-3s May Shield Women’s Brains, Study Finds
Health Points
- New research found women with Alzheimer’s had lower omega-3 levels than women without the disease, with no such difference seen in men.
- Omega-3 fatty acids, found in foods like salmon and walnuts, may offer unique brain protection for women, though more study is needed.
- Experts recommend omega-3-rich foods as part of a balanced diet for overall health benefits.
Women face a higher risk of Alzheimer’s, making this study’s findings especially relevant for those concerned about cognitive health. The research analyzed blood samples from over 800 people and revealed a link between low omega-3 levels and Alzheimer’s specifically in women.
Omega-3s are healthy fats that help build brain cells but must be consumed through food, as the body does not make them on its own.
“This suggests we need sex-specific approaches to understanding, diagnosing, and potentially treating Alzheimer’s disease,” said study author Cristina Legido-Quigley, PhD, from King’s College London.
The study observed higher levels of unhealthy saturated fats and lower levels of unsaturated fats carrying omega-3s in women with Alzheimer’s. Men did not show these changes, highlighting a sex-based difference in how the disease might develop.
“This study fills a critical gap by showing that lipid associations with Alzheimer’s disease were exclusively found in women,” Legido-Quigley explained, noting there were 32 significant changes in women but none in men.
Dr. Timothy Chang of UCLA said the study “builds on the evidence of lipids associated with Alzheimer’s disease in women.”
While these results are promising, experts caution that this type of research does not prove omega-3s prevent Alzheimer’s, and the findings may not apply to everyone, as the study focused on older European adults.
For now, adding omega-3-rich foods like salmon, sardines, chia seeds, flaxseeds, and walnuts to your diet can still offer overall health perks.
