Corn is a food that many people like to eat. It belongs to coarse grains, is nutritious, and has a sweet and delicious taste. It is also easy to digest, helps to help the stomach and intestines move and facilitates bowel movements.
So, what varieties of corn are available, and are these varieties suitable for everyone? Below, let's take a look at why eating corn is good for health. How to eat to be healthy.
In fact, corn does not have a particularly big gap, but compared with ordinary corn, waxy corn has a higher protein content, more than 10%, and is rich in a variety of vitamins, such as vitamin A, vitamin B1, etc. The molecular weight of starch in waxy corn is more than ten times smaller than that of ordinary corn, which is easier to be absorbed and digested by the human body, and data show that the digestibility of waxy corn is 20% higher than that of ordinary corn. Therefore, people with poor digestive function can eat more waxy corn.
However, although waxy corn is nutritious, it is not suitable for everyone, such as diabetics. Corn is one of the ideal foods for diabetics. Because corn contains low crude fiber and soluble sugar, for example, the sugar content in old corn is lower than that of ordinary rice, but the crude fiber content is 9 times that of rice.
Therefore, diabetics can eat some old corn appropriately. But waxy corn and sweet corn are best not to eat.
Sweet corn is rich in water-soluble polysaccharides, with a sugar content of 8%, and the sugar content of fortified sweet corn is higher, and most of them are sucrose and glucose, which can easily cause blood sugar to rise. Waxy corn is not suitable for diabetics because of its high amylopectin content. The higher the amylopectin content, the easier it is to convert to glucose.
Once consumed by the patient, their blood sugar rises faster.
People with normal blood lipids and blood sugar can usually eat more corn, and there is no need to distinguish which kind of corn can be eaten and which one cannot be eaten. Whole grains help the body to excrete and are good food for the body. Corn can improve the body's own immunity and help patients recover physically after illness.
For example, corn can be crushed and boiled into porridge, which can be appetizing and calming, and has a health care effect on patients with high blood pressure and coronary heart disease. You can also take 3 taels of corn silk and boil it into water to prevent and treat urinary tract stones.
