Medical research has identified various methods to mitigate the risks of cardiovascular disease and cognitive decline. Studies from King’s College London indicate that following specific dietary guidelines—including increased fruit and vegetable intake and reduced salt and sugar—can reduce the risk of heart attacks and strokes by up to one-third in adults aged 40 to 70.

In addition to dietary changes, vaccinations have been linked to reduced dementia risks. Research from Brown University suggests the herpes-zoster vaccine may protect against dementia by preventing chronic inflammation. Similarly, studies involving older Americans indicate a correlation between flu vaccinations and a lower risk of Alzheimer’s disease and dementia, with high-dose flu shots potentially reducing these risks by up to 40%.
