Nutritional Breakdown per 100g Serving
- Calories: 194 kcal
- Protein: 13.9g
- Fat: 3.64g
- Carbohydrates: 25.8g
- Fiber: 1.2g
- Sugar: 2.9g
- Net Carbs: 24.6g
Understanding the Numbers
The relatively high GI of 70 is primarily due to the white bread, which digests quickly and releases glucose rapidly into the bloodstream. While the roast beef provides quality protein (13.9g per serving), the sandwich’s overall carbohydrate content (25.8g) with minimal fiber (1.2g) results in significant net carbs (24.6g) that impact blood sugar.
Health Implications
For individuals monitoring blood glucose levels, particularly those with diabetes or insulin resistance, it’s important to note that this sandwich may cause quicker blood sugar rises than lower-GI alternatives. The moderate protein content can help slow digestion somewhat, but the high GI bread remains the dominant factor in blood glucose response.
Making It Healthier
Consider these modifications to improve the glycemic profile of your roast beef sandwich:
- Switch to whole grain or sourdough bread to lower the GI
- Add extra vegetables for increased fiber content
- Include avocado or olive oil-based spread to add healthy fats that slow digestion
- Increase the protein-to-carb ratio by adding more roast beef
The Bottom Line
A roast beef sandwich on white bread can be part of a balanced diet, but its high glycemic index means it’s best consumed alongside lower-GI foods or as part of a meal that includes additional protein and healthy fats to moderate the blood glucose response. For those closely monitoring their glycemic intake, consider the healthier alternatives suggested above.
