Clinical Trial Summary

Effect of a dietary supplement with Shiitake extracts (Lentinula edodes) on lipid profile and other cardiovascular risk factors in subjects with moderate hyperlipidemia without pharmacological treatment.

Description:

Prospective, parallel, randomized and double-blind clinical-nutritional study of 8 weeks of duration and 2 study groups (1) Food supplement with extracts of the fungus Shiitake; 2) Placebo supplement with maltodextrin) to evaluate the effect of a food supplement derived from the Shiitake mushroom (Lentinula edodes) on the lipid profile, other cardiovascular risk factors and the intestinal microbiota in subjects with hyperlipidemia moderate without pharmacological treatment.

Secondary	Change from Baseline Satiety Hunger Assessment	Visual Analogue Scale (VAS). 100mm horizontal line anchored at each end with the extremes of the subjective feeling to be quantified. Subjects are instructed to rate the sensation being experienced according to how they define the line.; e.g., "not at all hungry" (0mm) and "as hungry as I have ever felt" (100mm). Multiple measures are taken at repeated time intervals described below.	Week 0 and 8

Secondary	Change from Baseline Anthropometric Parameters	Waist Circumference	Week 0 and 8
Secondary	Sensory Perception	Questionnaire of analysis of sensory perception of the food study product. Five questions that are valued on a scale of 0% to 100% asking about the taste and smell of the study product: desire with which the product is taken, taste, smell, consistency and what wait for effectiveness.	Week 4
Secondary	Change from Baseline Glucose Parameters	Glucose	Week 0 and 8
Secondary	Change from Baseline Inflammation Parameters	PCR, fibrinogen, IL-6, IL-10, TNFalpha	Week 0 and 8
