not much..the human digestive system can not readily digest corn. this is why it is commonly seen whole in the feces. compared to other grains corn is virtually useless, it is high in vitamin K, besides that it's nothing special. corn is also high in sugar as compared to other grains, it is used to manufacture dextrose and maltodextrin which are 2 sugars with a GI of 100.

Like other grains, corn is a member of the grass family, but is distinguished from its relations by its relatively short growing season and its large seed head.
Although corn is the only grain eaten as a vegetable, Europe never really adopted the love for it that Americans did and fed most of it to their animals. This is quite the opposite of what happened with such other grains as barley and oats, where Europeans made them a staple food for humans, but Americans fed them to their animals.
There are more than 500 different by-products obtained from corn, with the flour and starch playing a major role in manufactured foodstuffs, as well as in the making of adhesives, pharmaceuticals, cosmetics, cloth, and paper. Glucose syrups made with corn are found in the majority of sweetened processed foods and drinks. A vast array of synthetic rubber can now be made in part from processed maize. Laundry starch, as well as the food starch, is made from corn. Cigarette papers are made from the inner husks, and explosives and packaging material are made from the pith. But the most popular form is in the very adulterated breakfast cereal. To make "corn flakes", the kernels of corn have their fiber and nutrient-rich outer layers removed, leaving the starchy kernel to be cooked, rolled, and toasted, followed by the addition of an assortment of synthetic vitamins, flavourings, salt, and sugar, rendering it nothing like the original grain.
Since there was no way for these early settlers to obtain fresh milk or dairy products (cows had not yet arrived from the Old World), mothers would mix crushed fresh corn with the juice of boiled hickory nuts and chestnuts to use as a baby food.
Corn is a high-carbohydrate, high-starch food. The carbohydrates in corn consist of sugar, starch, and food fiber, amounting to about 81% of the total content. The most plentiful sugar in sweet corn is glucose. Other nutrients include fat, calcium, potassium, iron, provitamin A, B complex vitamins, and Vitamin C; but not all of these nutrients are readily available to the human body. All varieties of sweet corn are good sources of Vitamin C and niacin. However, about 80% of the niacin is unavailable to the human body because it is bound into insoluble carbohydrate/protein/nitrogen compounds. Corn also has some non-heme iron, which is found in plant food and which the body does not absorb very well. Vegetarians have learned to circumvent this problem by eating foods rich in Vitamin C at the same time, helping the iron become better absorbed.
Corn is also a moderately good source of plant proteins but zein, its major protein, is deficient in the essential amino acids lysine, cystine, and tryptophan. By combining corn with a legume rich in these deficient amino acids, a complete protein dish has been created. For example, the traditional Latin American combination of corn tortillas and beans makes the meal complete in protein.
Central and South American peoples developed a number of delicious ways to eat maize, including a sweet porridge, the traditional tortilla, and, of course, tamales. In Mexico, tamales are a national dish traditionally made with meats dripping in fats and rolled in a corn paste, wrapped in corn husks, and then steamed. Our Mexican daughter-in-law, Martha, makes wonderfully delicious tamales without meats or fats, but instead, using beans, peppers, and other vegetables. This popular recipe is available only in her cookbook, however, which is given out during their Spanish-immersion programs.
There are also recipes made from corn on the website.
