Introduction
Components:
- ellagitannins, proanthocyanidins, anthocyanins, & other flavonoids
- pterostilbene
Pharmacokinetics
- ellagitannins, proanthocyanidins, anthocyanins, & other flavonoids in berrys are poorly absorbed & highly metabolized
- parent compounds, metabolites & conjugates detectable in human tissue Clinical manifestationw:
- discoloration of teeth & tongue
- blueberry consumption can improve endothelial function in healthy persons & at-risk populations[6]
- flavonoids including anthocyanins in blueberries may mitigate macular degeneration[6]
Clinical trials
- 12% improvement in memory over 2 year period in subjects age 50-84 consuming 1 cup of frozen blueberries/day; No study controls[2]
- lowers serum triglycerides (40%) & LDL cholesterol (20%)[3]
