Sweet corn, with its succulent kernels and sweet taste, is a favourite for many. But if you're living with diabetes, you may be wondering whether you can still enjoy this delicious treat. The good news is that sweet corn can indeed be a part of your diabetes-friendly diet when consumed in moderation. In this article, we'll explore the benefits of sweet corn for diabetes and also, you will learn more about why you should include corn on your plate (its nutritional value) and the effect of corn on your blood glucose (sugar) levels.
Glycemic Index of Corn:
Checking corn's glycemic index can allow you to quickly determine whether it is healthy for diabetics. The GI determines how food affects blood glucose levels.
Any Food items under 55 are considered as low GI, whereas food items with a GI of 56 to 69 are considered medium GI. Consuming foods with a GI of 70 or higher should be done with caution because they can raise blood sugar levels. Corn has a GI of 52, placing it in the low-to-medium range, which is generally beneficial for people with diabetes.
When exploring corn-based products, it's essential to be aware of their respective GI:
- Corn Tortilla: 46 (low GI)
- Popcorn: 65 (medium GI)
- Cornflakes: 81 (high GI)
How Corn Helps to Control Diabetes?
Corn can be a beneficial food for people with diabetes due to its nutrient composition and its effect on blood sugar levels. Also, it is found that the consumption of cornmeal is good for both type 1 and type 2 diabetes and it helps lower blood sugar levels.
Here are some ways corn can control diabetes:
- Abundant in Fibre: Corn is a rich source of dietary fibre, which can slow down the absorption of glucose into the bloodstream. This, in turn, helps in regulating blood sugar levels and prevents sudden spikes.
- Glycemic Index is Low: Compared to foods with a high glycemic index (GI), corn has a comparatively low GI, which implies it has less of an effect on blood sugar levels. Low GI meal options can enhance blood sugar control by reducing blood sugar spikes.
- Packed with Antioxidants: Corn is full of antioxidants like carotenoids and flavonoids. These antioxidants have anti-inflammatory properties and protect cells from damage. This is particularly important for people with diabetes, as they are more prone to complications related to chronic inflammation.
- Versatile in Cooking: You can prepare corn in many ways, from boiling and roasting to grilling. It can be added to salads, soups, and stews, making it easy to include in a diabetes-friendly diet and add variety to your meals.
Fresh, Frozen, or Canned Corn: Which is More Nutritious?
Fresh corn is the top choice, but when it's not around, go for frozen corn as the next best option—it keeps most of its nutrients when frozen. Canned corn, however, isn't as healthy because it often contains preservatives and added sugar. Don't worry about fresh corn raising blood sugar levels too much; it's okay in moderation for people with diabetes. So, to get the most nutrition, go for fresh or frozen corn over canned.
