To examine how omega-3 fatty acids interact with genetic variants in relation to cognitive decline and cardiovascular disease risk in older adults.
Conducted a systematic review of studies investigating omega-3 fatty acids and genetic variants.
Identified relevant literature from various databases regarding older adults.
Analyzed the interactions between dietary intake of omega-3 fatty acids and genetic predispositions.
Found that omega-3 fatty acids may have protective effects against cognitive decline.
Showed interactions between genetic variants and omega-3 intake influencing cardiovascular disease risk in older adults.
Research supports the potential role of diet in managing genetic risks during aging.
