Corn on the Cob: The Good, the Bad, the Recipes

Is corn actually good for you? We dig in and find out.

Corn is one of those foods that is confusing. As good as it is, there are many questions that swirl around about whether it is actually good for you. Here’s some juicy detail on corn and our opinion on how best to enjoy it this summer.

All About Corn

• Corn originated in Mexico over 9,000 years ago and is known by its original name “maize” in many parts of the world. Native Americans grew and harvested this crop as a main source of food.
• There arethree types of corn: sweet corn, field corn and Indian corn. We normally eat sweet corn and sometimes Indian corn for popcorn.
• Corn is astarchy vegetableandcereal grainthat is one of the world’s most popular. Corn is actually a seed of a plant in the grass family native to Central America.
• Corn is agood source of nutrients: fiber, vitamins, minerals, antioxidants.
• Corn is naturallygluten-free.
• Corn is a pretty good source ofproteinbut is not a complete protein (does not include all essential amino acids).
• Popcornis a good source of minerals: phosphorus which helps with growth and maintenance of body tissues; magnesium, which is used in SO many parts of the body including the heart; and copper which is actually not abundant in the western diet and also good for the heart. Popcorn also has vitamin E, CoQ10 and good phytosterols (antioxidants), all helpful for lowering cholesterol.
• Sweet Cornhas good vitamin Bs and some good amounts of potassium. It also contains antioxidantsZeaxanthin and Lutein, which are very helpful and protective to the eyes. Lutein specifically protects your eyes from the oxidative damage from blue lights (from our screens).

The Downside of Corn

• Corn and Sugar: Corn is high in starch, which may spike your blood sugar and is not great if you have blood sugar issues (prediabetes, diabetes, stubborn weight loss).
• Corn is sometimeshighly refinedto make high fructose corn syrup, corn oil, and those aren’t so good for you. Processed corn products lose beneficial fiber and other nutrients during production AND sometimes add salt, sugar or fat.
• Unlike other starchy carbs that turn primarily into glucose (rice),high fructose corn syrupis 50% glucose and 50% fructose, which is harder to digest because the fructose needs to be converted into glucose by the liver before it can be used as fuel in the body.
• Corn is oftengenetically modifiedand we don’t have a lot of info on what a genetically modified food DOES inside the body. Some suspect it is not as good for you as non-genetically modified foods.
• Corn has ananti-nutrient calledPhytic acid, which may impair your absorption of dietary minerals and make it harder to get the ‘goodness’ from corn.
• Corn ispotentially inflammatoryfor some. Corn contains zein proteins that are related to gluten and can be problematic for some. There have been some studies where corn has caused similar problems to those with gluten sensitivity or celiac disease.
• Potential Problems with IBS: Corn sometimes triggers reactions in people with irritable bowel syndrome (IBS) or FODMAP intolerance due to the large amounts of fiber, causing diarrhea, bloating and/or gas.
• Cornis used for fuel and animal feed. In fact, 40% of the corn grown in the US is used for fuel and 60–70% of corn worldwide is produced to feed animals.

So, YES or NO on choosing corn at the next BBQ?

As you can see, there’s not a cut and dry answer as to whether you should enjoy corn at the BBQ. In my opinion, enjoy corn in its most whole versions: corn on the cob, sweet corn salad and popcorn. SKIP the fried corn chips, corn oil or corn syrup. Always go with your gut – if you bloat, or corn makes you feel bad, avoid it! It might not be your body’s favorite food. If you feel good eating it, include it in your summer menus.
