Elderberry Consumption and Human Health

Completed · Not applicable · Has a placebo group

Conditions studied: Obesity, Unspecified

In brief

The objective of this human study is to determine if the metabolic benefits observed with other anthocyanin-rich berries extend to elderberries. To accomplish this, we performed a short-term controlled feeding study in overweight but healthy volunteers in a placebo-controlled crossover clinical trial. Major study endpoints included blood glucose and insulin response to a high-carbohydrate meal challenge, indirect calorimetry, and profiling of the fecal microbiome.
