Acai Extracts show Brain Health Potential

Wednesday, July 20th, 2011

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

Friday, June 3rd, 2011

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.

Eating for a strong immune system

Wednesday, April 27th, 2011

It’s hard for your body to fend off the viruses that cause winter infections like colds and flu if your nutritional status is below par. Most people know that vitamin C-rich foods like citrus fruits become particularly important during the winter months. But did you know that other foods may also support your defences against infection and help relieve the symptoms of colds and flu? Here are five of the most important immune system stimulating foods to include in your diet as the weather gets colder. (more…)

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.


Acai Berry and Antioxidants

Tuesday, November 3rd, 2009

The Acai berry is not your regular fruit!

One of the reasons for this is its high antioxidant content. You have probably heard over and over that there is consistent evidence in research that diets rich in fruit and vegetables and other plant foods are associated with better health. Sound familiar? Probably. So why is that?

1. Antioxidants

The Acai berry is not your regular fruit. One of the reasons for this is its high antioxidant content. You have probable heard over and over that there is consistent evidence in research that diets rich in fruit and vegetables and other plant foods are associated with lower mortality rates and lower death rates from cardiovascular disease and some types of cancer. Sound familiar? Probably. So why is that?

This association is partly given to the high content of antioxidants in fruits and vegetables, which protect our bodies against chronic disease by decreasing free radical oxidative damage. Our bodies are in constant attack by free radicals, which are a common by-product of normal metabolism. Think of free radicals as individuals with too much energy and no where to put it. So they are extremely active and attack everything in their path in our bodies, this translates to the damage of our cells and genetic material. In the long term, this may translate to permanent damage that is irreversible (such as cancer). In our day to day lives, we are further exposed to high amounts of free radicals through increased physical activity, stress, pollutants, chemicals and toxins. Antioxidants which are obtained through our diet act like scavengers, which seek and “relax” the free radicals. Once the free radicals are “relaxed”, they do no further damage.

So what kinds of antioxidants are in Acai?

Acai is rich in anthocyanins, compounds that provide colour to the fruits and serve as natural antioxidants. Those are the same compounds found in red wine. However, Acai pulp has 10-30 times more. Pure Dried Acai contains more, 70-210 times more! The richer the pigment colour of the fruit, the more antioxidants it generally has. One way to help you achieve a high antioxidant diet is to make sure your plate is very colourful. Ensure that you eat plenty of fruits and vegetables at your main meals, and snack on an Acai smoothie or other fruits and vegetables instead of lollies or chocolate.

Acai’s royal purple pigment not only makes the fruit appealing to eat, but studies have shown that berry anthocyanins are beneficial in reducing age-associated oxidative stress (or the free radical damage). If berries can combat premature aging with 25 to 40 times less antioxidants than Acai, then just imagine what Pure Dried Acai can do!

The US food industry is now labeling the antioxidants in food with ORAC (Oxygen Radical Absorbance Capacity). Data from the United States Department of Agriculture (USDA) suggests a serving of fresh fruit and vegetables has between 890 and 2,500 ORAC units. Just one 5g serving of RioLIfe organic freeze dried Acai will provide you with around 4,695 ORAC units!
