Prevent Diabetes, Hypertension and Obesity with Purple Corn

During our fifteen years living in Peru we’ve heard Peruvians boast about their unique strain of purple corn. It’s said to lower blood pressure so effectively that it’s contraindicated for hypotensive persons.

Purple corn is used in many Peruvian recipes, the most common being chicha morada or purple corn drink. It is sold in fine restaurants and even on the street, where it is ladled into a plastic bag and slurped with a drinking straw.

More Health Benefits of Purple Corn

Recently, we found information from scientific studies that confirm the truth of this age-old Peruvian wisdom. And not only does purple corn lower blood pressure, it also offers multiple health benefits not limited to the following*:

  • Powerful antioxidant action
  • Cancer-fighting properties
  • Anti-inflammatory
  • Regulates the function of fat cells, preventing accumulation of fat and controlling obesity
  • Regulates insulin, preventing diabetes
  • Encourages regeneration of connective tissue and formation of collagen
  • Protects cells from damage by free radicals
  • Reduces cholesterol levels
  • Detoxifies
  • Slows aging process


What makes purple corn such amazing ally to human health? Purple corn owes its intense purple pigment to the phytochemical anthocyanin, one of many plant chemicals known as flavonoids. More specifically, purple corn’s main colorant comes from the plant chemical cianidin-3-b-glucosa. And purple corn’s anthocyanins are stable when heated.

This article focuses on just a few of these health benefits: prevention of diabetes, hypertension and obesity. If you’d like to learn how to make chicha morada, Peru's purple corn drink, please click here: Chicha Morada: Peruvian Purple Corn Drink That Lowers Blood Pressure. You can also read a great article by Rajan Jolly about the benefits of any variety of corn by clicking here: Nutritional & Health Benefits of Corn or Maize.


Research on Purple Corn

To site just one study: Japanese researchers fed two groups of mice a high fat diet for 12 weeks. This diet caused hyperglycemia, hyperinsulinemia and hyperleptinemia in the control group. However, the group of mice fed purple corn extract didn’t gain weight nor did they have elevated levels of insulin, glucose or fat in their blood.1 These findings, as well as numerous other test studies performed in recent years, show that purple corn may prevent obesity and diabetes.

Regarding hypertension, we would like to mention a personal experience. A dear friend who suffers from hypertension began taking prescription medicine to reduce his blood pressure. Then he heard about the benefits of purple corn. He started a regimen of adding purple corn to his diet, taking 500 mg of purple corn extract 3 times daily before meals. The results? His blood pressure has decreased and he was able to stop taking the prescription medicine for hypertension. He owes his miraculous recovery to purple corn extract.* For that reason, nutritionists in Peru often prescribe purple corn to hypertensive patients.


Where Can You Find Purple Corn?

Purple corn is grown from low coastal valleys to the high Andes mountains of Peru. All varieties of purple corn originated from the line Zea Mays L. and are still cultivated in Peru. This line of corn is so old that ceramics in the shape of ears of corn have been unearthed in archaeological sites at least 2,500 years old. Purple corn was prized by Inca royalty.

Fortunately, Amazon offers purple corn on the cob, purple corn kernels, purple corn powder and even purple corn extract. Include some form of purple corn in your daily diet to see results.

    GetitScene, maybe a local farmer has grown a crop of purple corn. You never know--sometimes you can find it in North America. Thanks for the comment and votes!

    RTalloni, I'm glad you enjoyed reading about this unique purple corn from Peru. We have blue corn in North America, although the compounds that create the color are a little different. Thanks for coming by!

    Deborah-Diane, blue corn is actually different from purple corn, although they both contain the same compound that gives them their beautiful color. And yes, the blue corn chips are more wholesome than just yellow or white. Thanks for taking the time to read and comment!

    I like purple corn, but I had no idea that it had so many health benefits. I have even heard that corn chips made from purple corn (often called blue corn chips) are much more wholesome than other types of corn chips. Thanks for you interesting article.

    JustAskSusan, you might just be able to find it as many farmers like to try exotic crops. Many Peruvians swear by it to lower blood pressure, among other things. Thank you for your comment!

    I've had purple corn chips but not purple corn on the cob. I'll need to check out Amazon's offerings to try it out. Voting this Up and Useful.

    Aufait, purple corn seeds have been exported to other parts of the world and I've read about farmers who grow purple corn in the States, so it's very possible what you saw was from the Zea Mays L. line of corn cultivated in the Andes. I hope you can get some next time! Thanks so much for the vote and comment.

    Very interesting. I've seen ornamental corn that came in many colors including purple. It was also edible. I wonder if it's the same thing or must it be specifically Peruvian purple corn? Voted up and interesting!
