Corn: Kernels Against Cholesterol
June 25, 2013by Bree West
Though many think of corn as a vegetable, it’s actually technically a grain that grows in rows of kernels covered by a thick, fibrous husk. The most common type of corn is yellow, but there are many varieties that can range in color from white-yellow, red, pink, blue, and black, and they can further vary by being a solid color, striped, or multi-colored. Corn is best when it is eaten fresh, because this is when it has its best and juiciest flavor. Once corn is picked from the stalk, there begins to be decreases in the fluid content in the starch portion of the grain and therefore its moisture decreases and some of the grain’s sweetness is also lost. Like most other grains, when corn starts to dry out, it becomes hard and less sweet and less flavorful.
The use of corn goes as far back as 5000 B.C. in the areas known today as Central America and Mexico. Both Native Americans and the early colonists used corn as an important and sustainable staple to their diet. Interestingly, Pellagra, a disease that causes fatigue, rashes, and digestive inflammation, is caused by a lack of vitamin B3 (niacin), and eating a diet high in corn, without other sources of niacin, can make a person more susceptible to Pellagra because the niacin in corn is not easily absorbed by the body and therefore a deficiency can result. The Native Americans figured this out and started eating corn with some limestone that had been burned into ash. Though they didn’t know exactly why this helped, they observed that the people who ate the corn with the limestone ash were healthier than those who did not. Science today has found that the limestone ash, also known as potash, helps the body absorb niacin more easily. Many explorers loved corn and used it often, but did not prepare their corn with the limestone ash, and thus many of the settlers came down with Pellagra.
The different colors of corn are due to the variety of plant chemicals known as flavonoids and carotenes. These healthy plant chemicals are contained in the endosperm portion of the grain. The most common kind of corn used today, the yellow kind, is high in a carotenoid called lutein. Foods high in lutein can help to protect against heart disease and macular degeneration. Corn is also high in fiber, which makes it a helpful food for preventing constipation and other related digestive issues, and also provides other healthful benefits that a high-fiber containing diet has, such as balancing blood sugars. Corn has soluble fiber, which binds with bile and cholesterol. Bile is a fluid made by the liver from cholesterol and its function is primarily the digestion of fats. Soluble fiber binds to these and because the body does not absorb soluble fiber, the fiber and the excess cholesterol and bile are excreted, forcing the body to use the cholesterol left behind to make more bile. Thus corn is a good food for helping to lower high cholesterol levels.
While fresh corn can be a part of a healthy diet, and is itself a healthy food, corn by itself is not a nutritionally complete food. One way to obtain the nutrients needed to make corn a complete food is to eat it in tortilla form, which has cornmeal and limestone potash together, helping the niacin in the corn to be absorbed and utilized. Corn is also a good source of vitamin B1 (thiamine), B5 (pantothenic acid), B9 (folate), C, and E, and the minerals magnesium and phosphorus. Corn is low in protein, but is a good source of complex carbohydrates, essential fatty acids, and fiber. Because of corn’s complex carbohydrate content, it makes it a great food for fuel and energy.- 3 C Corn
