Modified food starch, particularly resistant wheat starch type 4 (RS4), is a common ingredient in keto-friendly foods․ It’s created to increase fiber content․ RS4, often called Fibersym, is designed to reduce the postprandial insulin response, meaning the pancreas releases less insulin after consuming it․

Impact on Blood Sugar
Studies show that while RS4 reduces insulin response, the glucose released into the blood remains similar to native wheat starch (NWS)․ Research indicates that the area under the curve (AUC) for blood sugar levels is comparable between RS4 and NWS․ However, the impact on peak blood sugar levels and duration isn’t fully understood from the initial study․ Resistant starches, in general, are reported to have a lower glycemic index, resulting in a lower glucose spike over a longer duration․
Further Research
Further analysis of available data might reveal more about the peak and duration of blood sugar spikes with RS4 compared to native wheat starch․ Meta-analyses of multiple studies suggest that type 1 and type 2 resistant starches offer potential benefits․

Types of Resistant Starch
Resistant starches are categorized into different types based on their origin and processing․ Type 1 includes starches found in unprocessed grains, seeds, and legumes․ Type 2 is present in raw potatoes and green bananas․ Type 3 is formed when certain starchy foods are cooked and then cooled, like cooked and cooled potatoes or rice․ Type 4, as mentioned earlier, is created through chemical modification․
Uses in Food Production
Modified food starch serves various purposes in the food industry․ It can be used as a thickener, stabilizer, or emulsifier․ It helps improve the texture, shelf life, and overall quality of processed foods․ Its ability to withstand high temperatures and acidic conditions makes it a versatile ingredient in a wide range of products, from sauces and soups to baked goods and snacks․
Considerations
While modified food starch is generally considered safe, some individuals may experience digestive issues, such as bloating or gas, especially with high consumption․ It’s essential to read product labels and be mindful of portion sizes․ People with specific dietary restrictions or sensitivities should consult with a healthcare professional or registered dietitian․
