Eating a high-quality plant-based diet later in life may lower one's risk of developing Alzheimer's disease and other forms of dementia, according to a new study published in the journal Neurology.
Researchers found these benefits even among participants who made dietary changes later in life, including in their late 50s and 60s.
The study followed participants for more than a decade. During that time, people who reduced their intake of unhealthy foods saw about an 11 percent drop in dementia risk.
Experts involved in the research say the key is focusing on nutrient-rich, whole foods. These include whole grains, fruits, vegetables and nuts, which may help protect brain function as people age.
