Plant-based diets, such as the DASH diet and MIND diet, can reduce the risk of heart failure and ultimately decrease the risk of cognitive decline and dementia.
Combining aerobic exercise with the heart-healthy DASH diet improved the ability to think, recall, and make decisions in older people who experienced cognitive decline and mild cognitive impairment.
Eating a diet rich in fruits and vegetables, moderate in nuts, fish and alcohol and low in meat and full-fat dairy is associated with better cognitive performance in middle age.
Researchers believe their new study will provide a mechanistic understanding of how our microbiome and diets can impact the development of Alzheimer's disease. The study will aim to provide evidence of possible diet induced effects on gut bacteria, which could influence age associated cognitive decline.
Researchers report people who follow the DASH diet may have lower rates of depression over time.
