BAA new study followed 365 adults aged 55 to 80 at increased risk for Alzheimer’s disease who consumed low amounts of omega-3 fatty acids. Half of participants carried the APOE4 gene, a strong genetic risk factor for the condition. Over two years, participants took either high-dose DHA supplements or a placebo. After six months, those taking fish oil showed an average 17% increase in DHA levels in cerebrospinal fluid, suggesting brain absorption. However, after two years, cognitive tests showed no significant difference between the supplement group and the placebo group. The study also found that supplements did not slow hippocampus volume loss, a marker linked to Alzheimer’s. Researchers suggest that fish oil alone may not protect against age-related cognitive decline and recommend a more holistic approach, including healthy lifestyle habits. Experts advise against using fish oil supplements solely for preventing Alzheimer’s or maintaining cognitive function, instead recommending whole foods rich in omega-3s like fatty fish, chia seeds, and nuts, along with medical advice.
Bias read (Center): The article presents a scientific study without overt ideological framing. It reports findings objectively, discusses both potential benefits and limitations of omega-3 supplements, and recommends a balanced, evidence-based approach. There is no clear leaning toward any political ideology, making it
