Eating plenty of fatty fish – such as salmon, mackerel, and sardines – could help protect women against Alzheimer’s disease, according to new research from King’s College London. The study examined blood samples from 841 adults, with 306 diagnosed with Alzheimer’s. Researchers noted a striking drop in levels of unsaturated fats, including omega fatty acids, in women with Alzheimer’s compared to healthy women. These fats are vital for brain health and can only be obtained through food – most notably oily fish.
Unlike women, men did not show any notable differences in these fat molecules, regardless of their Alzheimer’s status. This discovery may help explain why women are disproportionately diagnosed with Alzheimer’s, especially after the age of 80. Senior author Dr. Cristina Legido-Quigley said: “Our findings suggest women should ensure they are getting omega fatty acids in their diet – either through fatty fish or supplements.” However, she stressed that more clinical trials are needed to confirm whether changing dietary fats can influence the progression of Alzheimer’s.
These results further highlight the importance of a diet rich in “good fats” for women’s brain health, with omega-rich fish standing out as a key ingredient.
