The Core Culprits: Refined Flour and High Sugar
Most commercial biscuits are produced using refined wheat flour (maida) and added sugars. These ingredients are the primary drivers behind a biscuit's ability to spike blood sugar. The refining process strips wheat of its fiber-rich bran and nutrient-dense germ, leaving only the starchy endosperm. This makes the carbohydrates in refined flour highly digestible and causes them to convert into glucose almost immediately upon digestion, leading to a rapid surge in blood glucose. High levels of added sugars further exacerbate this effect, providing more readily available glucose and amplifying the impact.
Understanding the Glycemic Index (GI)
To understand how different biscuits affect your blood sugar, it helps to know about the Glycemic Index (GI). The GI is a rating system that shows how quickly a carbohydrate-containing food raises blood sugar levels.
- High-GI foods: Cause rapid, sharp spikes in blood sugar. Most standard, sugar-laden biscuits fall into this category due to their refined ingredients.
- Low-GI foods: Lead to a slower, more gradual increase in blood sugar. These are preferable for people managing blood glucose.
This is why healthier biscuits made with whole grains, nuts, or seeds often have a lower GI, as the fiber and other nutrients slow down glucose absorption.
Not All Biscuits Are Created Equal
While many popular, store-bought biscuits can significantly increase blood sugar, the market also offers healthier alternatives. This distinction is crucial for making informed choices.
| A Comparison of Biscuit Types | Feature | Regular Biscuits | Diabetic-Friendly/Low-GI Biscuits |
|---|---|---|---|
| Primary Flour | Refined wheat flour (maida) | Whole wheat, oats, ragi, almond, or coconut flour | |
| Sugar Content | High added sugar | Sugar-free or low added sugar, often using natural sweeteners like stevia or monk fruit | |
| Fiber Content | Low to minimal | High fiber, from whole grains and other ingredients | |
| Glycemic Impact | High Glycemic Index, causing rapid spikes | Low Glycemic Index, leading to a slower rise in blood sugar | |
| Nutritional Profile | Low in essential nutrients | Richer in vitamins, minerals, and healthy fats |
The Benefits of Fiber and Healthy Fats
Ingredients like whole grains, nuts, and seeds found in low-GI biscuits and other snacks play a vital role in blood sugar management.
- Dietary fiber: A type of carbohydrate that the body cannot digest, fiber slows down digestion and the absorption of sugar. This helps to stabilize blood glucose levels and reduces the post-meal spike. Both soluble and insoluble fiber are beneficial.
- Healthy fats and protein: These macronutrients also slow down the absorption of carbohydrates and contribute to a feeling of fullness, preventing overeating. Healthy fats can also improve insulin sensitivity.
Practical Tips for Snacking Wisely
To enjoy biscuits responsibly and minimize the impact on your blood sugar, consider these practical tips:
- Prioritize whole grains: Choose biscuits made with 100% whole grain flour or other high-fiber alternatives like oats and ragi. Check the ingredients list to ensure whole grains are at the top.
- Practice portion control: Even with healthier options, moderation is key. Stick to the recommended serving size to manage your overall calorie and carbohydrate intake.
- Read nutrition labels: Pay close attention to the grams of carbohydrates, added sugars, and fiber per serving. Avoid products with hidden sugars or excessive processed ingredients.
- Try homemade: Baking your own biscuits gives you full control over the ingredients, allowing you to use low-GI flours, natural sweeteners, and high-fiber additions.
- Pair with protein and fat: Eating biscuits with a source of protein and healthy fat, such as nuts or yogurt, can help to slow down the absorption of sugar.
Healthy Biscuit and Snack Alternatives
If you want to cut back on biscuits entirely, plenty of satisfying and blood sugar-friendly alternatives are available.
- Unsalted nuts and seeds: Excellent sources of healthy fats, protein, and fiber that help stabilize blood sugar.
- Whole-grain crackers with toppings: Pair with cheese, hummus, or nut butter for a balanced snack.
- Fresh fruit: Provides natural sugars with fiber, which helps to manage the glucose response.
- Roasted chickpeas or sprouts: High in protein and fiber, offering a savory, crunchy alternative.
- Yogurt with berries and seeds: A balanced snack rich in protein, fat, and fiber.

Conclusion
In summary, consuming traditional biscuits with refined flour and high sugar will likely increase blood sugar levels due to their high glycemic index. However, this doesn't mean you must avoid biscuits forever. By being mindful of ingredients, opting for high-fiber, low-GI alternatives, and practicing portion control, you can still enjoy a biscuit as part of a balanced diet. Prioritizing whole foods and healthier snack swaps can lead to better blood glucose management and improved overall health.
