Recent studies emphasize the significant impact of dietary and lifestyle changes on reducing dementia risk. Research from Harvard shows that replacing processed red meat with nuts, beans, or tofu can lower dementia risk by nearly 23% and reduce cognitive decline by 20%. Processed meats are linked to higher dementia risk due to harmful substances like nitrites and sodium. Additionally, weight-loss drugs like liraglutide show promise in slowing Alzheimer’s progression by reducing brain shrinkage and memory loss. Managing type 2 diabetes, especially early diagnosis, is crucial as it significantly increases dementia risk. Oral health, particularly preventing tooth loss, is also critical, with poor oral hygiene linked to higher dementia risks.
