Understanding the Glycemic Index (GI)
For individuals with diabetes, the glycemic index (GI) is a crucial tool. The GI is a rating system for carbohydrate-containing foods based on how quickly they affect blood glucose levels. Foods with a low GI (1-55) are digested and absorbed more slowly, causing a gradual rise in blood sugar. In contrast, high GI foods lead to rapid spikes. The type of flour used for roti significantly influences its GI, making the right choice essential for managing blood sugar effectively.
Popular Low-GI Flours for Roti
While regular whole wheat roti is a step up from refined white flour, incorporating alternative flours with a lower GI can offer even greater benefits for sugar patients. Here are some of the best options:
Millets: A Fiber and Nutrient Powerhouse
Millets like ragi (finger millet), jowar (sorghum), and bajra (pearl millet) are ancient grains gaining popularity for their health benefits. They are naturally gluten-free and have a low GI, which helps regulate blood sugar.
- Ragi (Finger Millet): This millet is an excellent source of calcium and has a high fiber content, which aids digestion and helps stabilize blood sugar. Ragi rotis are denser but are a great option for nutrient-rich meals.
- Jowar (Sorghum): Rich in fiber, protein, and essential minerals like magnesium, jowar is another low-GI choice that promotes better glucose control. Jowar rotis are known for being soft and easily digestible.
- Bajra (Pearl Millet): High in fiber and vital nutrients, bajra has a low GI, making it a suitable choice for sugar patients. Bajra rotis can be slightly coarse but are highly nutritious.
Legume-Based Flours: Protein and Fiber Combined
Legume flours are another excellent option, offering a high protein and fiber content that slows down digestion and glucose absorption.
- Besan (Chickpea Flour): This flour is rich in protein and fiber, helping to maintain steady blood sugar levels. Besan can be used to make traditional chillas or mixed with other flours for roti.
- Soy Flour: A great source of plant-based protein with a low glycemic impact, soy flour can be added to your regular atta to boost its nutritional profile.
Other Beneficial Flours
- Buckwheat Flour (Kuttu Atta): A gluten-free pseudograin, buckwheat has a low GI and is rich in the antioxidant rutin, which helps regulate blood sugar and cholesterol.
- Oat Flour: Contains beta-glucans, a type of soluble fiber that helps lower cholesterol and promotes a gradual release of energy.
- Multigrain Flour: A blend of different grains and legumes often provides a wide range of nutrients and a lower GI than plain wheat flour. When choosing, ensure it's a 100% wholegrain mix to avoid refined flour fillers.
Flour Comparison: A Quick Reference
To make an informed decision, here's a comparison of some common roti flour options based on their GI and other benefits.
| Flour Type | Glycemic Index (GI) | Key Benefits for Diabetics | Best For... |
|---|---|---|---|
| Ragi (Finger Millet) | Low (~50-55) | High fiber, calcium-rich, helps stabilize blood sugar | Nutrient-dense rotis |
| Jowar (Sorghum) | Low (~65) | High fiber and protein, gluten-free, soft texture | Soft, daily rotis |
| Bajra (Pearl Millet) | Low (~55-60) | High fiber, minerals, good for heart health | Flavorful, nutritious rotis |
| Besan (Chickpea Flour) | Low (~6) | High protein and fiber, very low GI, promotes satiety | Mixing with other flours, chillas |
| Whole Wheat | Moderate (~62) | Good fiber source, more accessible, lower GI than refined flour | Balanced daily use |
| Multigrain (Certified 100%) | Low | Rich in diverse nutrients, high fiber, lower GI than whole wheat | Variety and improved nutrition |
Practical Tips for Diabetic-Friendly Roti
Beyond selecting the right flour, your preparation methods and meal combinations can further enhance blood sugar management.
How to Prepare Roti for Lower GI
- Add High-Fiber Ingredients: Mix a tablespoon of ground flaxseed or psyllium husk into your roti dough. The added fiber slows down carb absorption.
- Use Warm Water: Kneading the dough with lukewarm water can help make millet-based rotis softer and easier to handle, as they lack gluten.
- Cooking Method: Opt for cooking rotis on a medium flame on a tava. Some sources suggest that cooking at higher temperatures for a shorter duration can affect the GI, though results vary.
The Importance of Balanced Meals
Eating roti alone can still cause a glucose spike. Combining it with other food groups can balance the meal and reduce its glycemic load.
- Pair with Protein: A side of dal, lentils, paneer, or chicken slows digestion and prevents sugar spikes.
- Include Vegetables: Fill your plate with high-fiber, non-starchy vegetables like spinach, cauliflower, and gourds. The fiber content further aids in blood sugar control.
- Add Healthy Fats: A small amount of healthy fats, such as ghee or olive oil, can help regulate blood sugar levels.
Conclusion: Making the Best Choice for Your Health
Choosing the best roti for sugar patients involves moving beyond refined white flour and exploring nutritious, high-fiber, and low-GI alternatives like millets and legume-based flours. Ragi, jowar, bajra, and besan are all excellent options that offer superior blood sugar control compared to plain whole wheat. For a well-rounded diet, certified 100% multigrain flours are also a great choice. Remember to focus on portion control and pair your roti with protein and fiber-rich vegetables to create a truly balanced, diabetes-friendly meal. Consulting a nutritionist can help you tailor these choices to your specific dietary needs.

Which roti is best for sugar patients?
Several flours are excellent for sugar patients, including ragi, jowar, bajra, besan, and certified 100% multigrain blends, as they all have a low glycemic index and are rich in fiber.
Can diabetics eat normal wheat roti?
Diabetics can eat normal whole wheat roti in moderation, but it has a moderate glycemic index. Low-GI alternatives like millets or besan are generally better for controlling blood sugar spikes.
How can I reduce the GI of my roti?
To reduce the GI of your roti, mix your regular flour with other low-GI flours like besan, ragi, or almond flour. Adding high-fiber ingredients like ground flaxseed or psyllium husk also helps.
Is multigrain flour better for diabetics?
Yes, a certified 100% multigrain flour is often better for diabetics than plain whole wheat flour because it combines a wider variety of grains, offering more fiber and nutrients and a lower overall glycemic index. Be sure to avoid blends with refined flour fillers.
How does fiber affect blood sugar?
Fiber slows the absorption of carbohydrates into the bloodstream, which helps prevent rapid spikes in blood sugar levels. This provides a more gradual and sustained release of energy.
Are gluten-free flours automatically good for diabetics?
No, not all gluten-free flours are good for diabetics. For example, rice flour and cornstarch are gluten-free but have a high glycemic index. It is important to choose gluten-free flours with a low GI, such as buckwheat or almond flour.
Should I add vegetables to my roti dough?
Yes, incorporating finely grated vegetables like spinach, cauliflower, or carrots into your roti dough can increase its fiber content, add nutrients, and help lower the overall glycemic load of your meal.
