A new study highlights that individuals with a family history of Alzheimer’s disease may reduce their risk by following a Mediterranean diet. Alzheimer’s is a progressive neurodegenerative disorder that affects memory, thinking, language, and problem-solving skills. While genetics, particularly the APOE4 gene, significantly influence susceptibility, lifestyle choices such as diet can play a key role in reducing risk.
Researchers found that people carrying two copies of the APOE4 gene benefit most from a Mediterranean-style diet, which modifies blood metabolites linked to dementia risk. The diet can offset up to 40 percent of the overall risk among high-risk individuals.
The Mediterranean diet, originating from countries around the Mediterranean Sea including Italy, Greece, Spain, and France, focuses on plant-based foods, nuts, olive oil, legumes, whole grains, yoghurt, and fish rich in omega-3 fatty acids. Its heart-healthy benefits are well-documented, and emerging research shows its potential in lowering neurodegenerative disease risk even in individuals with strong genetic predisposition.
Additional health benefits include improved glucose metabolism, insulin sensitivity, lipid levels, and reduced inflammatory markers, which also decrease the risk of heart disease. This diet demonstrates the powerful impact of modifiable lifestyle factors on diseases traditionally influenced by genetics, making it a practical strategy for long-term brain and heart health.
