Corn Flakes, Plain: A High-Glycemic Breakfast Cereal
Corn flakes are a popular breakfast cereal choice for many households. While they offer convenience and a crispy texture, it’s important to understand their nutritional profile and glycemic impact. Let’s explore what plain corn flakes bring to your breakfast table.
Glycemic Information
Our user-friendly app features a searchable database, meal planning tools, and personalized recommendations based on your health goals.
Plain corn flakes have a glycemic index (GI) of 81, which places them firmly in the high GI category. Foods with a GI above 70 are considered high glycemic foods that can cause rapid spikes in blood sugar levels.
The glycemic load (GL) is 61.56 per 100g serving. This is considered very high, as a GL above 20 is typically classified as high. The glycemic load takes into account both the quality (GI) and quantity of carbohydrates in a portion of food.
Nutritional Profile (per 100g serving)
- Calories: 365 kcal
- Protein: 6.4g
- Fat: 1.6g
- Total Carbohydrates: 79.5g
- Dietary Fiber: 3.5g
- Sugar: 9.44g
- Net Carbs: 76g
What This Means For Your Health
Corn flakes are primarily carbohydrate-based with minimal protein and fat content. With 76g of net carbs per 100g serving, they can cause significant blood sugar fluctuations, particularly for those with diabetes or insulin resistance.
The fiber content is relatively low at 3.5g per serving, providing minimal benefits for digestive health or blood sugar regulation.
Who Should Be Cautious With Corn Flakes?
- People with diabetes
- Those with insulin resistance
- Individuals following a low-carb diet
- People trying to manage blood sugar levels
- Those aiming for sustained energy throughout the morning
Healthier Alternatives
If you enjoy cereal but want lower glycemic options, consider:
- Steel-cut oatmeal (GI: 55)
- Bran cereals (GI: 30-40)
- Granola with nuts and seeds (check for added sugars)
- Muesli (unsweetened varieties)
How To Lower The Glycemic Impact
If you still prefer corn flakes, you can reduce their glycemic impact by:
- Adding protein (Greek yogurt, milk, or protein powder)
- Including healthy fats (nuts, seeds, or nut butter)
- Adding extra fiber (berries, chia seeds, or flaxseeds)
- Reducing your portion size
The Bottom Line
Plain corn flakes are a high-glycemic food with substantial carbohydrate content and limited nutritional benefits. While they may be convenient, they’re not the best choice for blood sugar management or sustained energy. Consider lower GI alternatives or ways to balance your corn flakes with protein, fiber, and healthy fats for a more nutritionally complete breakfast.
