Is Sweet Corn Safe for Diabetic Patients?
Yes, sweet corn can be safe for diabetic patients when eaten in moderation. It contains natural carbohydrates and sugar, which means it can slightly raise blood sugar levels. However, its low glycemic index (GI 52–55) and high fiber content help slow down sugar absorption and prevent sudden glucose spikes.
The key is controlling portion size and balancing sweet corn with protein or healthy fats.
Glycemic Index and Glycemic Load of Sweet Corn
The Glycemic Index (GI) represents how quickly a food raises blood sugar.
| Type | GI Value | Glycemic Load (GL) |
|---|---|---|
| Sweet Corn (boiled) | 52–55 (Low-GI) | 8–10 (Low-GL) |
Low GI and GL values mean that sweet corn releases sugar more slowly into the bloodstream, making it safer for diabetics compared to high-GI foods such as white rice or potatoes.
