Getting forgetful? Then blueberries may hold the key

11.04.2008
If you are getting forgetful as you get older, then a research team from the University of Reading and the Peninsula Medical School in the South West of England may have good news for you.

They have found that phytochemical-rich foods, such as blueberries, are effective at reversing age-related deficits in memory, according to a study soon to be published in the science journal Free Radical Biology and Medicine.

The researchers working at the Schools of Food Biosciences and Psychology in Reading and the Institute of Biomedical and Clinical Sciences at the Peninsula Medical School in Exeter supplemented a regular diet with blueberries over a 12-week period, and found that improvements in spatial working memory tasks emerged within three weeks and continued throughout the period of the study.

Blueberries are a major source of flavonoids, in particular anthocyanins and flavanols. Although the precise mechanisms by which these plant-derived molecules affect the brain are unknown, they have been shown to cross the blood brain barrier after dietary intake. It is believed that they exert their effects on learning and memory by enhancing existing neuronal (brain cell) connections, improving cellular communications and stimulating neuronal regeneration.

The enhancement of both short-term and long-term memory is controlled at the molecular level in neurons. The research team was able to show that the ability of flavonoids to induce memory improvements are mediated by the activation of signalling proteins via a specific pathway in the hippocampus, the part of the brain that controls learning and memory.

This innovative research was conducted by a multidisciplinary research team led by Dr. Jeremy Spencer, a lecturer in Molecular Nutrition at the University of Reading and included Dr. Claire Williams, a Psychologist also from Reading and Dr. Matt Whiteman, a Principal Investigator at the Institute of Biomedical and Clinical Science, Peninsula Medical School. Dr Spencer commented: “Impaired or failing memory as we get older is one of life’s major inconveniences. Scientists have known of the potential health benefits of diets rich in fresh fruits for a long time. Our previous work had suggested that flavonoid compounds had some kind of effect on memory, but until now we had not known the potential mechanisms to account for this”.

Dr. Whiteman added "This study not only adds science to the claim that eating blueberries are good for you, it also provides support to a diet-based approach that could potentially be used to increase memory capacity and performance in the future. Indeed, Dr. Spencer’s research team plan on extending these findings further by investigating the effects of diets rich in flavonoids on individuals suffering from cognitive impairment and Alzheimer’s disease.”

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
