Fiber

Corn is high in dietary fiber and sweet corn contains both soluble and insoluble fiber. A medium sized ear of corn provides nearly 10 percent of required daily value (DV) of corn. Canned sweet corn can be high in salt, with some brands containing as much as 545 mg of sodium per cup close to a quarter of the recommended dietary allowance. MayoClinic.com reports that excessive dietary salt can lead to fluid retention and increased blood pressure in sodium sensitive individuals; the website recommends getting no more than 2,300 mg of sodium a day.
