Abstract
The aim of this study was to investigate the effect of Hibiscus sabdariffa tea on energy expenditure, satiety response and food intake. This is an open-label, crossover, randomized clinical trial (RBR-5HZ86T), including 21 subjects (11 women, 10 men). The individuals were evaluated at acute moments (fasting and after eating standardized breakfast accompanied by water or Hibiscus sabdariffa tea). Resting energy expenditure was measured by indirect calorimetry, subjective satiety responses were evaluated with a visual analogue scale and food intake was assessed by using food records. The volunteers who drank the Hibiscus sabdariffa tea had lower perception of hunger (p=0.002) and greater feeling of satiety (p=0.010) and fullness (p=0.009) compared to control. Men who ingested the Hibiscus sabdariffa tea had an increase in nitrogen energy expenditure (water: 1501±290.7kcal, Hibiscus sabdariffa tea: 1619±288.9kcal; p=0.029). In comparison to control, men presented less perception of hunger (p=0.003) and desire to eat (p=0.016), increased satiety (p=0.021) and fullness (p=0.010), and women oxidized more fat (p=0.034) when they drank Hibiscus sabdariffa tea. There was no difference between treatments regarding the energy and macronutrient intake from the first meal and throughout the day (p>0.050) for all participants. The Hibiscus sabdariffa tea only affected energy expenditure and satiety responses in men. Clinical trial registry: ReBEC Platform of the Brazilian Clinical Trials Registry - RBR-5HZ86T Novelty bullets • Hibiscus sabdariffa tea promoted an increase in energy expenditure and caused less perception of hunger/desire to eat in men. • Hibiscus sabdariffa tea intake increased postprandial fat oxidation in women.

Abstract
Collagen is characterized by its high content of glycine, proline and hydroxyproline, and is found to exert beneficial effects on joint pain related to activity and osteoarthritis. However, to exert any beneficial effects it is essential that collagen is optimally absorbed. This study aimed to investigate the postprandial absorption of collagen and elucidate the impact of an exogenous enzymatic hydrolysis on absorption rate and bioavailability. A randomized, blinded, cross-over study was conducted where ten healthy male subjects received either 35 g enzymatically hydrolyzed collagen protein (EHC), 35 g non-enzymatically hydrolyzed collagen protein (NC) or placebo (250 mL water) on three nonconsecutive days. Blood samples were drawn before, and up to 240 min following, ingestion and the blood metabolome was characterized by nuclear magnetic resonance (NMR)-based metabolomics. A significant increase in the plasma concentration of nearly all amino acids (AAs) was observed over a 240 min period for both EHC and NC. In addition, the absorption rate and bioavailability of glycine, proline and hydroxyproline were significantly higher for EHC (p < 0.05). In conclusion, ingestion of collagen hydrolysates increases postprandial plasma concentrations of AAs over a period of 240 min, and an enzymatic hydrolysis increases the absorption rate and bioavailability of the collagen-rich AAs glycine, proline and hydroxyproline.
