A new study highlights the neuro-protective potential of cranberries
Adding cranberries to your diet could help improve memory and brain function, and lower ‘bad’ cholesterol, according to new research from the University of East Anglia (UK).
Lead researcher Dr David Vauzour, from UEA’s Norwich Medical School, said: “Dementia is expected to affect around 152 million people by 2050. There is no known cure, so it is crucial that we seek modifiable lifestyle interventions, such as diet, that could help lessen disease risk and burden.
The research team investigated the impact of eating cranberries for 12 weeks on brain function and cholesterol among 60 cognitively healthy participants.
Half of the participants consumed freeze-dried cranberry powder, equivalent to a cup or 100g of fresh cranberries, daily. The other half consumed a placebo. The study is one of the first to examine cranberries and their long-term impact on cognition and brain health in humans.
The results showed that consuming cranberries significantly improved the participants’ memory of everyday events (visual episodic memory), neural functioning and delivery of blood to the brain (brain perfusion).
Dr Vauzour said: “We found that the participants who consumed the cranberry powder showed significantly improved episodic memory performance in combination with improved circulation of essential nutrients such as oxygen and glucose to important parts of the brain that support cognition, specifically memory consolidation and retrieval.”
The study was supported by a grant from The Cranberry Institute. It was led by the University of East Anglia in collaboration with researchers at the Leiden University Medical Center (Netherlands), the University of Parma (Italy) and the Quadram Institute (UK).
