New Technology-Blueberries...Strongest Antioxidant Effect
11/19/2007 - A new study using the cellular antioxidant activity (CAA) assay, dubbed the 'next step' in quantifying antioxidant activity, has added to reports of blueberry's antioxidant prowess.
The test moves the quantification of antioxidant activity from the test tube to measuring bioactivity inside cells, and marks an advance in the understanding and activity of antioxidants.
"We've taken the next step toward understanding antioxidant activity by examining how antioxidants react with cells," said Rui Hai Liu, lead authors of the new study published in the Journal of Agricultural and Food Chemistry.
"This new approach is more biologically relevant as it accounts for uptake, metabolism, distribution and activity of antioxidant compounds in cells versus solely looking at antioxidant value," added Liu.
Applying the new technique to extracts from wild blueberries, cranberries, apples, red and green grapes, Kelly Wolfe and Liu from Cornell University report that blueberry topped the CAA rankings, followed by cranberry, apple, red grape, and finally green grape.
I wonder how they compare to currents. any idea Harry?
Hey what does your avatar say?
I think it's impossible to say - using this new testing method. This is just the start of such testing (which I think may have a more direct application to what really occurs once we ingest such foods).
Using the ORAC model, black currants are actually quite similar to blueberries (higher in some phytochemicals and lower in others).
Check out the table presented on page 40 of this book:
:WoW! What a book. We recently purchased some land and have been trying to figure out what to grow there and after finding out that currents grow well in the area I've been thinking more about them. I'm gonna have to get this. Thanks Harry!
