研究概览
简要总结
Hypothesis: A functional olive oil tailored to provide the best relationship between phenolic compounds (amount and type) phenolic bioavailability and bioactivity (antioxidant and anti-endothelial dysfunction) will be a useful tool for increasing not only circulating HDL cholesterol concentration, but also the functionality (antioxidant, anti-inflammatory, and reverse cholesterol transport capacity) of human HDL in vivo.
详细描述
The first step is to determine, in healthy human subjects in postprandial condition, the best relationship between phenolic compounds (amount and type) / bioavailability and bioactivity (antioxidant, anti-inflammatory and anti-endothelial dysfunction) using olive oils enriched with its own broad-spectrum phenolic compounds.

结局指标
主要结局
