Currently, more than 16 million people in the United States are living with cognitive impairment and the number is expected to rise as the aging population increases. Two of the most prevalent neurodegenerative disorders among older adults include Alzheimer’s and Parkinson’s disease. With limited available treatment, modifiable factors such as a diet rich in antioxidants and other essential nutrients for brain health are of substantial public health interest.

One such diet is the Mediterranean-DASH Intervention for Neurodegenerative Delay, or MIND Diet, which emphasizes natural plant-based foods, includes berries and green leafy vegetables as primary components, and limits the intake of red and processed meat and high sugar and fatty foods. In a prospective study of older adults, those who most closely followed the MIND dietary pattern, had a slower cognitive decline over time and 53% reduced risk of developing Alzheimer’s dementia (AD).

Berries are a key component in the MIND Diet because they are rich in anthocyanidins and other bioactives that have antioxidant and anti-inflammatory properties. In population-based studies, berry intake and its bioactivity are associated with better cognitive and motor function and reduced Alzheimer’s dementia risk. Strawberries are particularly rich in vitamin C and the anthocyanidin pelargonidin. Pelargonidin has a been shown to have a neuroprotective effect. Similarly, blueberries are a good source of vitamin K, C, and other anthocyanidins, including quercetin and myricetin, and have a positive effect on brain health. 

On Tuesday, January 11, 2022, from 2-3 pm ET, please join Puja Agarwal, PhD, Assistant Professor, Rush Alzheimer's Disease Center, Rush University Medical Center, Chicago, for a webinar that will address the role that berries, including strawberries, can play in a diet that optimizes brain health.
