Understanding the Glycemic Index
The glycemic index (GI) is a system that ranks foods containing carbohydrates based on how quickly they raise blood sugar levels. A GI score of 55 or less is considered low, 56-69 is moderate, and 70 or higher is considered high. Foods with a low GI are digested more slowly, leading to a gradual and sustained rise in blood sugar, while high GI foods cause rapid spikes. For individuals monitoring blood sugar, such as those with diabetes, choosing low to moderate GI foods is generally recommended for better glycemic control. The GI of oats is not a single number, as it varies significantly based on the type of oat and its processing.
The Effect of Processing on Oat Glycemic Index
The physical structure and processing of oat grains are the most significant factors determining their GI. Whole oat groats, which are the least processed form, have the lowest GI. When oats are processed further, their GI increases because the starch becomes more accessible to digestive enzymes.
How Different Oat Types are Processed:
- Steel-Cut Oats: These are oat groats that have been chopped into two or three smaller pieces with steel blades. This minimal processing means they have a lower GI and are digested slowly, providing sustained energy.
- Rolled Oats (Old-Fashioned): These are steamed and then rolled into flat flakes. The steaming partially cooks the oats, and the flattening increases the surface area, causing them to cook faster and have a slightly higher GI than steel-cut oats.
- Instant Oats: These are pre-cooked, dried, and cut into very small pieces to ensure the fastest possible preparation time, sometimes as little as 90 seconds. This extensive processing breaks down the starch and significantly increases the GI, causing a faster and higher blood sugar spike.
The Glycemic Index of Better Oats Products
Better Oats offers a variety of oatmeal products, including Instant and Quick-Cooking Steel Cut options. The GI of each product will depend on its level of processing and any added ingredients.
For example, a pouch of Better Oats 100 Calorie Maple & Brown Sugar Instant Oatmeal contains not only highly-processed quick-cooking rolled oats but also added sugars and artificial flavors. The combination of highly processed oats and added sugar will result in a much higher GI compared to a simple, plain bowl of less-processed oats. Conversely, their Quick-Cooking Steel Cut variety is a better option, having undergone less processing than instant oats, and is likely to have a lower GI, especially in unflavored versions.
Factors That Influence the GI of Your Better Oats Meal
- Level of Processing: The more processed the oat, the higher its GI. Instant oats will always have a higher GI than steel-cut oats.
- Added Sugars: Many flavored Better Oats packets contain added sweeteners, which drastically increase the overall GI and prompt a larger blood sugar response. Opting for plain or unsweetened varieties is a key strategy for managing GI.
- Toppings and Add-ins: Pairing your oats with protein and healthy fats, such as nuts, seeds, or yogurt, can help lower the overall glycemic load of your meal.
- Cooking Method: The longer you cook oats, the more gelatinized the starch becomes, which can slightly increase the GI. Soaking oats overnight also helps lower the GI.
Comparison of Different Oat Product Glycemic Index
| Oat Product Type | Processing Level | Approximate GI | Notes | 
|---|---|---|---|
| Better Oats Instant | Highly processed (pre-cooked, rolled thin) | High (Approx. 75-83, depending on flavor) | Often includes added sugars, raising GI higher. | 
| Better Oats Quick-Cooking Steel Cut | Moderately processed (cut and partially cooked) | Moderate (Similar to regular steel-cut) | Better choice than instant, lower GI. | 
| Rolled Oats (Traditional) | Moderately processed (steamed and rolled) | Moderate (Approx. 55-60) | A classic, versatile option with lower GI than instant. | 
| Steel-Cut Oats (Unbranded) | Minimally processed (chopped) | Low (Approx. 42-55) | Lowest GI option, takes the longest to cook. | 
Conclusion: Making the Right Choice for Glycemic Control
Ultimately, there is no single glycemic index for Better Oats, but rather a range that depends on the specific product and preparation. For those seeking to minimize blood sugar spikes, the company's quicker-cooking options are not ideal, especially if they contain added sugars. A much better choice for glycemic control is to select the most minimally processed oat type available, such as steel-cut oats, and prepare them yourself to control ingredients. Adding protein and fiber-rich toppings can further help stabilize blood sugar and prolong satiety. Making informed choices based on processing level and ingredients is the most effective way to manage the glycemic impact of your oatmeal.

Optimizing Your Oatmeal for Better Blood Sugar
Here are some tips for enjoying oatmeal with a lower glycemic impact:
- Choose the right type: Prioritize steel-cut oats, or quick-cooking steel-cut options over instant varieties, especially flavored ones.
- Add protein and fat: Include nuts, seeds (like chia or flax), and nut butter to slow down digestion and stabilize blood sugar.
- Watch the sugar: Avoid pre-sweetened packets. Use natural sweeteners sparingly and enhance flavor with spices like cinnamon.
- Use the right liquid: Cook oats with milk or a milk alternative instead of just water to add protein and fat content, which can help lower the glycemic response.
- Prepare overnight oats: This method uses a cold process that has been shown to lower the GI compared to cooked oats.
Key Takeaways
- GI Varies by Processing: The glycemic index of Better Oats depends on the product's processing level; instant oats have a higher GI than steel-cut oats.
- Added Sugars Increase GI: Flavored instant packets, which often contain added sugars, significantly increase the glycemic response.
- Steel-Cut is Best: Better Oats Quick-Cooking Steel Cut is a better choice for blood sugar management than their instant varieties.
- Combine with Protein and Fat: Adding nuts, seeds, or nut butter to oatmeal helps lower the overall meal's glycemic load.
- Control Your Ingredients: To ensure the lowest possible GI, choose plain oats and sweeten them naturally, using fiber and protein-rich toppings.
FAQs
Question: Is Better Oats instant oatmeal good for diabetics? Answer: Better Oats instant oatmeal, particularly the pre-flavored and sweetened varieties, is not the best choice for diabetics due to its high glycemic index. The rapid processing and added sugars can cause blood sugar to spike quickly. Plain, minimally processed oats like steel-cut are a better option.
Question: Does adding flax seeds to Better Oats affect the glycemic index? Answer: Yes, adding flax seeds, which are high in fiber and healthy fats, can help lower the glycemic load of your oatmeal. The added fiber slows down the digestion of carbohydrates, leading to a more gradual rise in blood sugar.
Question: How can I lower the GI of instant Better Oats? Answer: To lower the GI of instant Better Oats, choose a plain, unsweetened variety if possible. Add toppings rich in protein and fiber, such as nuts, seeds, or a scoop of protein powder. Mixing with milk instead of water can also help.
Question: Do Better Oats steel-cut oats have a low glycemic index? Answer: Yes, Better Oats Quick-Cooking Steel Cut oats have a lower glycemic index compared to their instant oatmeal products because they are less processed. Steel-cut oats are generally considered a low-GI food.
Question: What is the difference in GI between instant and steel-cut oats? Answer: Instant oats can have a GI as high as 83, while steel-cut oats have a GI in the low-to-moderate range (approximately 42-55), demonstrating a significant difference in their impact on blood sugar.
Question: Why do instant oats have a higher glycemic index? Answer: Instant oats have a higher GI because they are heavily processed, which breaks down the starches and makes them easier for the body to digest. This rapid digestion leads to a faster and more pronounced increase in blood sugar levels.
Question: Is the GI of Better Oats different from other brands? Answer: The GI is not brand-specific but is determined by the oat type and added ingredients. Better Oats' products will have a similar GI to comparable products from other brands—instant will have a high GI, and steel-cut will have a low GI.
