## Resource

Alzheimer's disease is expected to affect nearly 78 million people worldwide by 2030, making research into supportive lifestyle and dietary factors more urgent than ever Bottlenose dolphins develop the same brain changes seen in Alzheimer's patients, giving researchers a new way to study how memory loss unfolds Research associates a fat called C15:0, found in full-fat dairy and pasture-raised meats, with lower inflammation markers and stabilized neurotransmitter signaling related to memory and mood Observational studies have linked higher C15:0 levels with lower rates of diabetes, liver disease, and cardiovascular conditions that share metabolic pathways with brain aging Replacing seed oils with traditional saturated fats, increasing dietary C15:0 from full-fat dairy and pasture-raised meats, and discussing C15:0 supplementation with a qualified health care provider may form part of a broader strategy for supporting brain and metabolic health as you age
