HVN1917 Tahi Metadata Record - Tuhauora ka tahi: Effects of kawakawa containing beverage on the energy metabolism and physiology in healthy human volunteers

This metadata record and it's attached files make statements about the kinds of data collected as part of this research, and set out policies for governance of that data, now and in the future.<b>Description: </b>Kawakawa (Piper excelsum) a native NZ plant species, of cultural importance to Maori, and extensively used in rongoa Maori (traditional Maori healing). Despite considerable matauranga Maori of the therapeutic benefits of Kawakawa, research into the pharmacology of kawakawa is progressed little beyond identification the chemical profile. Kawakawa is reported to contain a number of pharmacologically active compounds demonstrated to influence pathways related to thermogenesis. We aim to explore the effect of adding kawakawa to a commercial beverage containing kiwi fruit powder and extracts of turmeric and ginger that has been formulated to stimulate postprandial thermogenesis. We hypothesise that consumption of the kawakawa-containing beverage will yield postprandial thermogenesis, measured as metabolic rate (energy expenditure) and respiratory quotient (relative substrate utilisation), proportional to the sum of that yielded by consumption of the beverage without kawakawa and that from an equivalent volume and strength of kawakawa tea.
