Dose Response Bioavailability of Coffee and Green Tea Antioxidants in Humans

2014-08-27 03:15:05 | BioPortfolio

Summary

Coffee and green tea are 2 widely consumed beverages. Both contain polyphenol antioxidant compounds (chlorogenic acids for coffee and catechins for tea). The bioavailability of catechins is somewhat known and has been referenced in the literature. However, bioavailability data from tea infusion is non-existent, even though it reflects better how consumers drink this beverage. In addition, bioavailability of coffee chlorogenic acids is less understood and no dose response study has been reported so far in the literature. Thus, there is a great need to understand and reinforce our knowledge on the bioavailability of coffee and tea polyphenol compounds.

Medical and Biotech [MESH] Definitions

Algae of the division Chlorophyta, in which the green pigment of CHLOROPHYLL is not masked by other pigments. Green algae have over 7000 species and live in a variety of primarily aquatic habitats. Only about ten percent are marine species, most live in freshwater. They are more closely related to the green vascular land PLANTS than any other group of algae.

Healthy People Programs are a set of health objectives to be used by governments, communities, professional organizations, and others to help develop programs to improve health. It builds on initiatives pursued over the past two decades beginning with the 1979 Surgeon General's Report, Healthy People, Healthy People 2000: National Health Promotion and Disease Prevention Objectives, and Healthy People 2010. These established national health objectives and served as the basis for the development of state and community plans. These are administered by the Office of Disease Prevention and Health Promotion (ODPHP). Similar programs are conducted by other national governments.
