Randomized Controlled Trial
Protein supplementation enhances cerebral oxygenation during exercise in elite basketball players.
The aim of the present study was to examine cerebral oxygenation during high-intensity exercise in elite basketball players who consumed supplements with different whey protein contents after a short postexercise recovery to determine whether changing whey protein content in carbohydrate-based supplementation influences cerebral hemodynamic response when the supplement was consumed during a 2-h recovery after a 1-h exercise challenge. ⋯ Enhanced fatigue recovery after consumption of a high-protein supplement is associated with enhanced cerebral oxygenation against exercise challenge, which spares brain blood demand for periphery.

Randomized Controlled Trial
Postprandial glucose and insulin response to a high-fiber muffin top containing resistant starch type 4 in healthy adults: a double-blind, randomized, controlled trial.
VERSAFIBE™ 2470 resistant starch (RS) is an RS type 4 that is derived from high-amylose maize starch,70% total dietary fiber (TDF; AOAC method 2009.01). This was a randomized, double-blind, crossover study to evaluate the postprandial blood glucose and insulin responses of healthy adults (n = 28) after the consumption of a muffin top made with VERSAFIBE™ 2470 RS (11.6 g TDF fiber muffin top) or a control muffin top (0.9 g TDF). ⋯ This study demonstrated that the inclusion of a practical dose of dietary fiber (11.6 g TDF) from VERSAFIBE™ 2470 RS in a bakery product significantly reduced postprandial glucose and insulin responses in healthy adults.
