Blue, sometimes purple, or Hopi corn is a variety of grain. The crop gets its name from the Native American tribe that developed this variety. Mexico is considered the birthplace of corn, and the genetic diversity of this grain is particularly great here. It can be not only blue but also dark gray to navy blue. It is used as a food and beverage coloring, especially in the production of chicha morada (a traditional Peruvian drink).
Beneficial properties
The crop's blue color stems from the high levels of anthocyanins, which provide the plant with powerful antioxidant properties. Anthocyanins are a group of plant pigments that impart coloration to plants, ranging from pink to dark blue or purple. Blue corn differs from regular corn not only in color but also in its 20% higher protein content.
Despite the abundance of varieties, people grow only a few for themselves. Hopi corn is a variety that matures in 100-120 days and grows to a length of about two meters. The kernels are sweet and nutty.
Anthocyanin content
This is a water-soluble pigment. This substance is very beneficial for humans. Blue corn supplies the body with a large amount of anthocyanin. It has anti-inflammatory and healing properties and helps slow the aging process of the skin. It has a positive effect on blood vessels and slows the progression of vascular diseases. The grain contains more antioxidants than, for example, blueberries, so this product can confidently be considered a healthy choice.
Polyphenols in the composition
Polyphenols are powerful antioxidants found in large quantities in vegetables (grains and other types). They can reduce the risk of cardiovascular disease. Antioxidants prevent the formation of atherosclerotic plaque in arteries, help lower blood pressure, and protect against blood clots.
Prevents the development of cancer
Scientists know that certain foods contain compounds that can protect against certain types of cancer. Japanese scientists have discovered that a pigment found in corn can prevent the development of colon cancer. Colon cancer is one of the most deadly types of cancer. However, the mechanism by which these trace elements work has not yet been fully elucidated.
Lutein in the composition
The human body cannot synthesize lutein, so its intake is directly related to diet. Lutein is essential for eye health: it can reduce color vision impairment, allowing for clearer vision and the ability to distinguish fine details. Including blue corn in your diet can reduce the risk of cataracts and macular degeneration, one of the leading causes of blindness.
Other vitamins
Blue corn contains three times more protein, six times more calcium, four times more zinc, and six times more iron than yellow corn. Given its high vitamin content, especially iron, it's recommended for children and pregnant women.
Metabolism places great demand on these elements.
Pure product
Blue corn kernels are contaminated with mycotoxins at levels several times lower than the permissible limits. Mycotoxins are naturally occurring toxic substances produced by certain types of mold fungi. They parasitize grains and other crops. Since contamination levels are several times lower than the permissible limits, corn can be considered an especially clean product. It is virtually uncontaminated by the environment. Therefore, it can be included in health-promoting diets.
This type of grain has long fed humanity, but only now, through scientific research, have the most valuable varieties been identified. Hopi corn is extremely healthy and should be included on tables not only for its unusual appearance but also for its vitamins and health benefits.
