Wondering if you can have corn on a keto diet? Get all the facts on the carb content of corn, low-carb corn substitutes, plus the best keto-friendly corn recipes.

Corn comes in many forms and can be used to make a wide variety of foods. Also known as maize, this versatile crop can be eaten as kernels, on the cob, ground into flour or incorporated into dishes like polenta, tortillas and cornmeal.
From snacks like popcorn and corn chips to corn oil, starch or syrup, you could easily consume corn at every meal of the day without even knowing it.
Is Corn Keto?
Unfortunately corn is not keto-friendly. If you’re following a ketogenic diet or another low-carb diet, you’ll definitely need to limit your intake of corn.
According to the USDA, a 100-gram corn provides a whopping 19 grams of carbs. One cup of corn kernels has 27 grams of carbs. To put that in context, one cup of diced potatoes contains 26 grams of carbs.
For most people on a ketogenic diet, the aim is to consume less than 50 grams of carbs per day. This means that a single serving of corn could blow through more than half of your daily carb allowance! For stricter keto diets with a lower carb intake, a serving of corn may end up exceeding your limit for the day.
