Secondly, corn contains glutathione, which can be handcuffed with your own "handcuffs" to inactivate it and excrete it through the digestive tract. It is also a powerful antioxidant, which can inactivate free radicals that accelerate aging and is the most effective anticancer substance in human body.
Finally, lutein in corn can also prevent colorectal cancer, skin cancer, lung cancer and uterine cancer, and zeaxanthin can prevent skin cancer and lung cancer.
Need to remind everyone that corn belongs to coarse grains, so you can't eat more. It needs to be mixed with flour and rice to better absorb nutrition.
Different colors of corn have slightly different health care effects, mainly because they contain different varieties of pigments:
Compared with white corn, purple corn contains more anthocyanins, so it has antioxidant and anti-aging effects. Yellow corn contains carotene and zeaxanthin, which is good for maintaining vision health.
Different tastes of corn have different nutritional values. Sweet corn is sweet and delicious, and is deeply loved by people. There is also a kind of "fruit sweet corn", which can be eaten raw like fruit. The content of protein, fat and vitamins in this sweet corn is 1 2 times higher than that in ordinary corn, and the content of selenium is 8-10 times higher. Among 17 amino acids, 13 is higher than that of common corn. However, sweet corn has a high sugar content, mostly sucrose and glucose, which easily leads to an increase in blood sugar.
How to cook corn is more nutritious? Many people always like to peel off the skin and clean the corn beard when buying corn, but this is unscientific. It is best to buy corn with skin.
This is because the husk can protect the moisture in corn from evaporation, thus maintaining its taste. When cooking corn, it is also best to peel off the outermost thick skin of corn, leaving the innermost two thin skins, and at the same time, wash the corn whiskers, so as to retain the unique flavor of corn and make it easier to cook. Generally, corn can be boiled for about 8 minutes. When the corn is ripe, you'd better drain it at once, otherwise the taste of the corn will not be rich. It should be reminded that the soup made of corn husk and corn stigma is called "Longxu Decoction", which is suitable for patients with diabetes and hypertension.
The most common practice of corn is to peel off the outermost thick skin of corn, leaving the innermost two thin skins, removing the stigma of corn and washing it.
Put the corn in the pot and add water. The water doesn't reach the surface of the corn. After the fire boils, add salt, cover the pot and cook for 8 minutes.
The ripening time of sweet corn and sticky corn is different. If you cook in the same pot, after cooking for 8 minutes, take out the sweet corn first, and then continue to cook the corn for 2 minutes. (that is, sweet corn is cooked for 8 minutes and sticky corn is cooked for 10 minute).
It is best to drain the cooked corn immediately, and don't soak it in boiling water for a long time, otherwise the taste of corn will not be rich.
The other is to cook corn in a pressure cooker. Generally, the pressure cooker can boil in 3-5 minutes after opening (the safety valve is steaming).
When eating boiled corn, you should first choose tender corn, keep a layer of corncob skin, and don't discard corn whiskers for cooking. If the water does not exceed the corn, cook it for 20 minutes. Cooked corn is nutritious and tastes sweet.
There is also water for boiling corn, which is a treasure, because it has corn stigma, which can clear away heat and benefit water and is very helpful for health care.
