Carbohydrates play a crucial role in our diet and have a significant impact on blood sugar levels. Making informed choices about the types of carbohydrates we consume is essential for maintaining stable blood sugar levels and overall health. In this article, we will dive into the effects of refined carbohydrates on blood sugar spikes, identify healthy carbohydrate choices for stable blood sugar levels, discuss the role of complex carbohydrates in maintaining balanced blood sugar, and compare the effects of simple and complex carbs on blood sugar response.
Why you might get conflicting advice
The glycemic index of foods is important, but it only tells part of the story when understanding how foods will influence your blood sugar. The rest is explained by the number of carbohydrates in your usual serving size of food. To properly weight both of these factors, use the glycemic load of your serving size, found by:
Glycemic Load per serving = (Carbohydrates per serving) x(Glycemic Index)
When we’re only comparing grains, the variation of carbohydrates per gram does not vary that dramatically but the portion you consume likely will. Few of us will eat more than a cup of rice (the dry serving size), but an equivalent serving of pasta will not usually fill you up.
As a general rule, avoid serving refined grains (like white rice or pasta) as part of the main dish if you would like to reduce your blood sugar spikes.

Impact of Refined Carbohydrates on Blood Sugar Spikes
Refined carbohydrates, such as white bread, white rice, and sugary foods, are processed and stripped of their natural fiber and nutrients. Consuming refined carbs leads to a rapid spike in blood sugar levels due to their quick digestion and absorption. This triggers a corresponding surge in insulin production, which can strain the body’s insulin response over time and contribute to insulin resistance and the development of type 2 diabetes.
The Role of Complex Carbohydrates in Maintaining Balanced Blood Sugar
Complex carbohydrates are made up of longer chains of sugar molecules and are found in foods such as whole grains, vegetables, and legumes. They provide a steady supply of glucose due to their slower digestion and absorption. This gradual release helps maintain balanced blood sugar levels, preventing sharp fluctuations and providing sustained energy. Complex carbs also offer additional health benefits, including higher fiber content and a richer nutrient profile.
High-Fiber Carbohydrates and Their Influence on Blood Sugar Control
High-fiber carbohydrates are an essential component of a blood sugar-friendly diet. Dietary fiber, found in whole grains, fruits, vegetables, and legumes, slows down carbohydrate digestion and absorption. This results in a slower and more controlled release of glucose into the bloodstream, reducing blood sugar spikes and promoting better blood sugar control. Fiber also enhances satiety, aids in weight management, and supports overall digestive health.
Comparing the Effects of Simple and Complex Carbs on Blood Sugar Response:
Simple carbohydrates, such as those found in processed sweets and sugary beverages, are made up of one or two sugar molecules. They are quickly broken down and absorbed, leading to rapid spikes in blood sugar levels. In contrast, complex carbohydrates contain longer chains of sugar molecules and take longer to digest. This slower digestion results in a more gradual release of glucose into the bloodstream, leading to a milder and more sustained blood sugar response.
