Usually happens that the experts made the content analysis based on polyphenols “removable” but a Spanish scientific discussed in detail the chemical composition of apple, pear and tangerine and discovered that there orta class of polyphenols called “non – Removable, which outweigh the “removable” by up to 5 times. The study was published in the Journal of Agricultural and Food Chemistry.

“This family of polyphenols must be extracted from cell walls using a variety of fruit acids,” said Dr. Sara Arranz Spanish Council for Scientific Research (CSIC) in Madrid. He added: “If these compounds are not considered non-extractable is underestimating the true amount of material” healthy “–

For his part, Dr. Paul Kroon, professional of the same institute, also said that “in the human body these compounds activated by fermenting bacteria that live in our digestive system, creating metabolites that may be beneficial, for example, by their activity antioxidant.

The Spanish research group headed by Professor Fulgencio Saura-Calixto, has been working to prove that non-extractable polyphenols, which are beyond most of the analysis and are not generally considered in nutritional studies, are an important part of bioactive compounds diet.

“These polyphenols are important components of the diet and add significant health properties. It is therefore necessary to reinforce the concept of eating plenty of fruit every day” concluded Saura-Calixto.
