Acai Extracts show Brain Health Potential

Extracts from Acai may enhance the ‘neuronal housekeeping function’ & potentially protect the brain as we age, suggests new research.

The brain’s natural housekeeping mechanism is called autophagy and involves the controlled degradation of cells, including the recycling of toxic proteins. This system declines naturally as we age, but new research suggests that berry extracts may enhance the process and contributes towards brain health.

Researchers at the USDA’s Human Nutrition Research Center on Aging at Tufts University in Boston presented their findings recently at the Society of Neuroscience annual meeting in San Diego.

Super fruits from Central and South America

Acai berries (pronounced ah-sigh-ee), have long formed part of the staple diet of Indian tribes. With the appearance of a purple grape and taste of a tropical berry, it has been shown to have powerful antioxidant properties thanks to a high level of anthocyanins, pigments that are also present in low levels in red wine.

It is presently being sold in a number of countries, including New Zealand, Australia, South America, Japan, USA, and the Middle East

New data

Led by the late James Joseph from Tufts University, the researchers investigated the anti-inflammatory effects of acai extracts in the main defense cells of the brain – the microglia – in rodents. “Microglial activation can result in the generation of cytotoxic intermediates and is associated with a variety of age-related and neurodegenerative conditions,” explained the researchers.

Results presented in San Diego indicated that extracted fractions of the acai pulp protected against the release of pro-inflammatory compounds including COX-2 and TNF-alpha.

“These results suggest that acai may contribute to ‘health span’ in aging, as it is able to combat some of the inflammatory and oxidative mediators of aging at the cellular level,” wrote the researchers.

Antioxidants Against Skin Ageing

Your skin is the barrier between your body and the outside world, and every day it is exposed to pollution, sunlight, cigarette smoke and other factors that impact its health and appearance. All of these, as well as many of the body’s normal physiological processes, can culminate in the production of free radicals.

Antioxidants for eye health

Being able to see clearly is a precious gift, and one that we often take for granted. How different would your life be if you couldn’t read, drive, or see the faces of your family and friends?

As we get older, many of us will experience failing vision. Often the remedy can be as simple as getting an updated prescription for your glasses, but serious eye problems such as cataracts and age-related macular degeneration (AMD) are also increasingly common, and can have a significant impact on your sight.

It pays to do everything you can now to prevent these conditions affecting you later. One key step you can take is to ensure your diet includes an abundance of antioxidants.
