Overview

• A UK Biobank analysis of roughly 122,000 adults found higher intakes of flavonoid-rich foods, including berries, were associated with a lower incidence of dementia over nine years.
• Harvard’s Nurses’ Health Study reported that women who ate more blueberries and strawberries showed slower memory decline by up to about two and a half years compared with low intakes.
• Small clinical trials in older adults suggest blueberry interventions can improve certain memory measures and increase brain blood flow and activation on imaging.
• Drawing on these findings, Presscription promotes a “Brainy Blue Breakfast Smoothie” that blends blueberries, yoghurt or kefir, flaxseed or chia, walnuts, milk, and optional banana and ice.
• Reports highlight anthocyanins in blueberries and ALA from walnuts and flaxseed and cite NHS guidance on protein, while noting that prevention claims require larger randomized trials.
