Brief Summary

The goal of this project is to elucidate interactions between the gut microbiome, anti-inflammatory/anti-oxidant food metabolomic signatures, and human inflammation phenotypes. Inflammation plays both direct and indirect roles in the development of type 2 diabetes (T2D), atherogenic cardiovascular diseases, and other causes of morbidity and mortality. Aronia melanocarpa (Aronia berries) are rich in bioactive polyphenolic compounds, which have been shown to lower inflammation and favorably impact metabolism. However, there is tremendous inter-individual variability in the bioavailability of polyphenolics and production of bioactive phenolic metabolites in the colon that depends, at least in part, on digestive metabolism by the gut microbiota. Little is known about the complex interactions among the gut microbiome, anti-inflammatory food metabolomic signatures, and human inflammation phenotypes. This study will utilize a systems-level approach to disentangle these complex interactions. The specific study objectives are as follows:

  1. 1.to determine the impact of Aronia supplementation on inflammation, metabolic health, and gut microbiome composition
  2. 2.to determine the static and dynamic metabolomic signature of Aronia based on an Aronia supplementation period and responses to a high-fat meal challenge

PLACEBO COMPARATOR

The placebo supplement will have no polyphenol content and will consist of 100 mL of the following mixture: black cherry Koolaid, blue and red food coloring, sucrose and sorbitol. This placebo will match the sugar content of the chokeberry juice. Dose of 100 mL is consumed once daily for duration of 28-30 day supplementation period.

Other: Placebo

Aronia

EXPERIMENTAL

100 mL of Aronia juice. Dose of 100 mL is consumed once daily for duration of 28-30 day supplementation period.

Dietary Supplement: Aronia juice

Interventions
