Corn is a delicious and versatile starchy vegetable that comes in many different variations. However, are all types of corn safe during pregnancy?

Corn is safe and healthy to consume during pregnancy when taking precautions for food safety. Corn is an excellent source of vitamin A, vitamin C, soluble fiber, and more. 

From sweetcorn to fresh corn and corn flour to corn soup, let’s discuss the benefits and safety of corn during your pregnancy. 

Is Sweetcorn Good For Pregnant Women? The Benefits

Sweetcorn is a variation of corn that can be white, yellow, or multi-colored and has over twice the sugar and sweetness of regular corn (source: Colorado State University). It is rich in vitamin C, vitamin A, soluble fiber, and antioxidants. 

Vitamin C, also known as ascorbic acid, primarily functions in the body to support a strong and healthy immune system. It also plays a crucial role in bone health, blood vessel formation, and wound healing (source: Mayo Clinic). Vitamin C also helps your body absorb and utilize iron from the diet.

Additionally, vitamin A, found in corn as beta-carotene, promotes healthy vision and eye health. Since beta-carotene is from plant sources, it cannot build up to toxic levels in the body (source: University of Rochester Medical Center). It promotes a healthy reproductive system and supports immune health.

Both vitamin A and vitamin C are antioxidants that help protect cells in the body again harmful molecules called free radicals. Free radicals are naturally produced in the body when it breaks down food, gets exposed to solar radiation, etc. Antioxidant consumption can help reduce inflammation in the body, leading to chronic health conditions.

Sweetcorn, amongst all types of corn, is rich in soluble fiber. Soluble fiber is a version of dietary fiber that can be dissolved in water (and other fluids in the body). It helps support a healthy gut microbiome, the community of good bacteria in the gastrointestinal tract (source: Cleveland Clinic).

A healthy gut microbiome can protect against obesity, diabetes, and other chronic health conditions.

Overall, soluble fiber can lower cholesterol levels by lowering the amount of fat the body can absorb (source: Cleveland Clinic). This cholesterol decrease can reduce the risk of heart disease, including high blood pressure, heart attack, and stroke.

When consuming canned corn, it is essential to clean the lid of the can before you open it to prevent bacteria from the outside surface from contaminating the food. It is also crucial to ensure that the can is free of dents, cracks, or lids that appear bulging (source: FDA).
