A study carried out by a group of researchers of the Basic Science Institute at the University of Veracruz shows that blue corn extract could help improve blood pressure, lipid profiles and adipose tissue.
The scientists developed an experiment where a group of rats were fed with a high sugar and high cholesterol diet and given blue corn extract while others were not. Those that received the extract showed an improvement of systolic blood pressure, their HDL or good cholesterol, and triglyceride levels. Also, they had a smaller increase in abdominal fat than the other rats not fed the blue corn extract.
An article on the study, written by the experts from the University of Veracruz and co-authors from other Mexican universities has been published on the Journal of Medicinal Food. It explains that the natural antioxidants present in blue maize may help prevent metabolic syndrome or risk factors like obesity, cardiovascular disease and diabetes. These natural antioxidants are anthocyanin, pigments compounds of low molecular weight that poses various chemical properties that provide these healthy benefits.
The anthocyanin is also responsible for the blue coloring of the corn, reason they are only present in blue and purple corns and fruits. Meanwhile, white corn only has 3 percent of the amount of anthocyanins that blue corn have.
