4. Corn has no real nutritional benefits.
Sweet corn is loaded with lutein and zeaxanthin, two phytochemicals that promote healthy vision. A midsize ear (about 3/4 of a cup) also offers a helpful 3-gram dose of dietary fiber.
5. Yellow corn is the best type of corn.
While corn lovers often have favorite varieties, most farmers agree that the variety is far less important than freshness, and that color is not a key to quality.
Corn shopping tips: Avoid corn with dry, pale husks and silks that are excessively dry at the point where they enter the cob. If pricked, kernels should squirt whitish juice. As for choosing the best-tasting corn, don’t buy a cob that’s more than 24 hours out of the field (feel free to ask your grocer how fresh the corn in the produce section is). If you’re buying frozen or canned corn, these rules don’t apply, since, in general, corn is frozen or canned at the very peak of freshness.
