Updated: Feb 26, 2020
Some studies indicate consuming foods rich in anthocyanins, such as purple corn, has been linked to the prevention, or delayed onset, of degenerative diseases of aging, cardiovascular disease, diabetes, cognitive dysfunction, and cancer.
This particular study focused on whether taking a concentrated dose of purple corn extract would have an effect on blood pressure. Those selected for the study were men and women, between 21 and 70 years old with prehypertension or stage 1 hypertension.
A double-blind placebo-controlled randomized crossover trial was conducted. Patients were randomly selected to 1 of 2 groups. Group 1 took the placebo capsule first then the purple corn extract capsule. Group 2 took the purple corn extract capsule first and then the placebo. The study spanned from September 2010 to August 2011, with four phases conducted, each 3 weeks in length.
By the end of the study, results showed that “blood pressure readings decreased from baseline levels after taking a purple corn extract capsule for 3 weeks, regardless of age, gender, body mass index level, or initial average blood pressure reading. Notably, Individuals who had higher blood pressure readings at baseline showed the most marked reduction in systolic and diastolic readings.”
