  • grape
  • Each easy-to-swallow capsule contains 100 mg of grape seed extract (95% polyphenols) and 200 mg of rose hips. (nutritionexpress.com)
  • Lead author Amy Cheah says there is a growing body of evidence about the antioxidant health benefits of grape seed tannins or polyphenols as anti-inflammatory agents and, more recently, for their anti-cancer properties. (ift.org)
  • phenolic
  • Polyphenols and phenolic acids found in the honey vary according to the geographical and climatic conditions. (hindawi.com)
  • The definition further states that polyphenols display unique physical and chemical behaviors related to their high molecular weights and profusion of phenolic substructures-precipitation of proteins and particular amine-containing organics (e.g., particular alkaloid natural products), and formation of particular metal complexes (e.g., intense blue-black iron(III) complexes). (wikipedia.org)
  • The raspberry ellagitannin (M.W. ~2450), on the other hand, with its 14 gallic acid moieties (most in ellagic acid-type components), and more than 40 phenolic hydroxyl groups, meets the criteria of both definitions of a polyphenol. (wikipedia.org)
  • Individual polyphenols engage in reactions related to both their core phenolic structures, their linkages, and types of glycosides they form. (wikipedia.org)
  • The phenolic unit can be found dimerized or further polymerized, creating a new class of polyphenol. (wikipedia.org)
  • metabolism
  • Chapters highlight the anti-inflammatory activity of polyphenols on key dendritic cells, how they modulate and suppress inflammation, and how they are inactivated or activated by metabolism in the gut and circulating blood. (elsevier.com)
  • Polyphenols have proven effective for key health benefits, including bone health, organ health, cardiac and vascular conditions, absorption and metabolism, and cancer and diseases of the immune system. (elsevier.com)
  • Consumption
  • The most common UV/Vis spectrophotometry assay involves the monitoring of the formation of o-quinones, which are the products of polyphenol oxidase-catalysed reactions, or the consumption of the substrate. (wikipedia.org)
  • Other possible effects may result from consumption of foods rich in polyphenols, but are not yet proved scientifically in humans so are not allowed as health statements by regulatory authorities like the U.S. Food and Drug Administration (FDA). (wikipedia.org)
  • intake
  • The reviewers stated that research to date had been of poor quality and that large and rigorous trials are needed better to study the science, and to investigate possible adverse effects associated with excessive polyphenol intake. (wikipedia.org)
  • biological
  • Tea polyphenols known as catechins are key components with many biological functions, including anti-inflammatory, antioxidative, and anticarcinogenic effects. (hindawi.com)
  • citation needed] The polyphenol content of wines is usually evaluated by the Folin-Ciocalteu reagent which correlates well with alternative chemical and biological procedures for determining antioxidant potential. (wikipedia.org)
  • vegetables
  • Chemistry Professor Joe Vinson, Ph.D., explained that popcorn is approximately 4% water, compared to 90% in most fruit and vegetables - meaning that polyphenols are much more diluted in the fruit and veggies. (medicalnewstoday.com)
  • and vegetables such as broccoli, cabbage, celery, onion and parsley are rich in polyphenols. (wikipedia.org)
  • olive oil
  • To date the European Food Safety Authority, which is scientifically assessing health claims made on food products, has rejected all claims on polyphenols except for olive oil. (eufic.org)
  • anticancer
  • Some natural polyphenols share the properties of some anticancer drugs such as etoposide and doxorubicin while other polyphenols may induce DNA mutations in the MLL gene, which are common findings in neonatal acute leukemia. (wikipedia.org)
  • found
  • The polyphenols found in tea also appear to suppress the growth of harmful bacteria, while promoting beneficial bacteria in the gut. (wisegeek.com)
  • occurs
  • Currently, lack of knowledge about safety suggests that polyphenol levels should not exceed that which occurs in a normal diet. (wikipedia.org)
  • beneficial
  • Unlike vitamins and minerals, polyphenols are not essential nutrients meaning that they are not required by the human body for sustaining life but they can exert beneficial functions. (eufic.org)
  • The demonstration of the beneficial effects of polyphenols will be sensitized by high-fructose feeding for the last 6 days of the protocol. (clinicaltrials.gov)
  • evaluate
  • Because cancer is so complex and it can be influenced by many environmental and genetic factors, scientists are reluctant to say that tea polyphenols will categorically prevent cancer, although rates do seem to be lower in tea drinkers after controls for other obvious factors like diet are used to evaluate the data. (wisegeek.com)
  • definitions
  • The report provides a basic overview of the industry including definitions, classifications, applications and industry chain structure.The Tea Polyphenols market analysis is provided for the international markets including development trends, competitive landscape analysis, and key regions development status.

  • effects
  • Studying and isolating the effects of polyphenols is not as easy task, and more research is needed. (eufic.org)
  • In this work, the complement-modulating activities, the inhibitory activities on nitric oxide (NO) production in LPS-induced RAW 264.7 macrophages and effects on cell viability of these polyphenols were studied. (mdpi.com)
  • Some polyphenols, particularly from the flavan-3-ol (catechin-type), have both anticarcinogenic-proapoptotic and mutagenic effects. (wikipedia.org)
