ORAC's tarnished reputation doesn't diminish polyphenols' health benefits, expert says

ORAC's tarnished reputation doesn't diminish polyphenols' health benefits, expert says | Longevity science | Scoop.it
It has been almost a year since United States Department of Agriculture took down its ORAC database.  Now that this official reference point is gone, does this measure of antioxidant potential still have relevance in the marketplace?
Ray and Terry's 's insight:

Using the ORAC scale to understand antioxidant content in relative terms can still be useful. Comparing foods on this scale provides information that you can use to rank foods and evaluate the health benefits of a particular fruit or benefit in relation to others.

>> Research on the antioxidants found in red wine has shown that they may help inhibit the development of certain cancers (see Question 1).
>>Resveratrol has been shown to reduce tumor incidence in animals by affecting one or more stages of cancer development. It has been shown to inhibit growth of many types of cancer cells in culture (see Question 2).
>>Evidence from animal studies suggests this anti-inflammatory compound may be an effective chemopreventive agent in three stages of the cancer process: Initiation, promotion, and progression (see Question 3).
Ray and Terry's 's insight:

There is a long standing body of research indicating that resveratrol and other polyphenols can help maintain healthy cellular activity, discouraging certain types of cancer.

WHFoods: Black beans | Longevity science | Scoop.it

Lowered colon cancer risk that is associated with black bean intake in some research studies may be related to the outstanding IF content of this legume.

 

 

Ray and Terry's 's insight:

Black beans have a higher polyphenol content than other beans. Colors in foods often indicate nutrient levels in this way.

 

Soaking beans helps reduce the tannin levels, as well as the compounds that make digestion difficult or gassy in many individuals.
