Eating berries can help protect the brain against ageing and ward off memory loss, scientists have discovered.
Strawberries, blackberries and blueberries contain high levels of compounds called polyphenolics, which help the brain to carry out essential ‘housekeeping’ functions.
Eating fruits with deep orange, red or blue pigments can even reverse the loss of brain power, according to a two month study of laboratory rats fed a berry-rich diet.
Shibu Poulose, who presented his research at the American Chemical Society on Monday, said: “The good news is that natural compounds called polyphenolics found in fruits, vegetables and nuts have an antioxidant and anti-inflammatory effect that may protect against age-associated decline.”
Polyphenolics in berries help certain cells called microglia, which clean up toxic proteins linked to age-related memory loss and other symptoms of mental decline.
Shibu Poulose, who has conducted research with the U. S. Department of Agriculture-Agricultural Research Service (USDA-ARS) Human Nutrition Research Centre on Ageing in Boston, explained: “In ageing, microglia fail to do their work, and debris builds up.
“In addition, the microglia become over-activated and actually begin to damage healthy cells in the brain.
“Our research suggests that the polyphenolics in berries have a rescuing effect. They seem to restore the normal housekeeping function. These findings are the first to show these effects of berries.”
Poulose said people should eat the whole fruit, which contain hundreds of health-boosting chemicals.


Home Care Regulation

Recently there have been various media reports of the Health, Information and Quality Authority (HIQA) closing down some residential homes because of infringements of the regulatory standards in place. This is a positive action, protecting elderly and vulnerable people, however Home Care Plus feels that there should be a similar control of the home care sector.
While residential homes have in built supervision from the simple fact that there are always various personal working, home care in contrast is very often a one to one situation in a private residence and as such the client is more open to poor work practices and abuse.
Home Care Plus feels very strongly that the home care sector in Ireland should be regulated and come under the remit of HIQA. While there would be a delay to bring in the relevant legislation giving HIQA a supervising role, an interim measure could be to enforce the National Quality Guidelines already drawn up in conjunction with industry stakeholders and the HSE. These have been in the corridors of power for several months now without having being implemented.
Home Care is too important a sector to leave unregulated. It would be a pity not to adopt a proactive rather than a reactive approach to ensuring that the home care sector in Ireland is working to international best practise standards.
