Is Corn Good for Diabetes? A Detailed Guide

Corn, be it roasted, curried, or fried with spices, is a staple in Indian households. Eating boiled corn kernels in cups or simply seasoning them with chilli, lime juice, and butter brings back nostalgic memories. There is no doubt that corn is a kitchen favourite, a very familiar food. However, most people with diabetes shy away from corn due to its carbohydrate content and sweet taste. So, is corn good or bad for diabetes? Let’s find out. 

Is Corn Diabetic Friendly?

People with diabetes often have to consider whether or not they can eat a particular food, where the glycemic index and glycemic load become deciding factors. The Glycemic Index (GI) measures how quickly sugar from any food gets absorbed into your bloodstream. Glycemic Load (GL) indicates how much sugar from any food gets absorbed into your bloodstream. 

Coming back to corn, it has low to moderate GI and GL, depending on the variety and how you cook it. The GI of boiled corn is 52, making it a low-GI food suitable for people with diabetes. Similarly, sweet corn has a moderate glycemic load value of 15 and a GI value of 52. Therefore, eating corn in moderation does not cause any unhealthy spike in your blood sugar levels. 

Every 100 grams of sweet corn offers 19 grams of carbohydrates, 3.2 grams of proteins, and 1.18 grams of fat, which can be a healthy addition to your diabetes diet in moderate quantities. Further, a study says that individuals with insulin resistance significantly improved their gastrointestinal health and glycemic response after consuming corn. 

The question remains, can corn raise your blood sugar? The short answer is yes. Too much corn raises blood sugar to a certain extent because it is still a starchy food group. Always stick to the optimum portion size if you plan to use corn or its varieties as a diabetic snack. Ultimately, you can add moderate quantities of corn to your meals with no guilt. However, avoid eating it if you have a corn allergy. 

The HealthifyMe Note 

Corn’s glycemic index and glycemic load do not cause any significant blood glucose spikes. However, sweet corn has a high level of natural carbs or sugar, so a person with diabetes should have it in moderate quantities.
