Brief summary:
Anthocyanins are phytonutrients that provide blue, purple and red colors to fruits and vegetables. The purpose of the study is to determine whether absorption of anthocyanins occurs in the acid pH of the stomach and to determine whether altering stomach pH by use of an over-the-counter medicine, Prilosec TM, alters absorption of anthocyanins from strawberries and blackberries.
