Recent research explores the complex link between nutrition and the risk of dementia, including Alzheimer's disease.

Malnutrition can be a risk factor for the development of Alzheimer's disease, but also a consequence of its progression. Previous research suggests that a Mediterranean diet may reduce the risk of Alzheimer's, thanks to the consumption of fruits, vegetables, nuts and whole grains, and a reduction in red meat, saturated fats and ultra-processed foods.
