Soybean Glycemic Index: Nutritional Facts

For a 100-gram serving of soybeans, the glycemic index (GI) is approximately 15, which is classified as low.¹ This means soybeans have a minimal impact on blood sugar levels, making them an excellent choice for those managing diabetes or looking to stabilize energy levels.

​

Soybeans contain about 9 grams of carbohydrates per 100 grams serving.² To calculate the glycemic load (GL), which provides a more practical measure of how a typical serving size affects blood glucose, we use the formula:

​

GL = (GI x Carbohydrates per Serving) / 100

​

Applying this formula:

​

GL = (15 x 9) / 100 = 1.35

​

Thus, the glycemic load of a 100-gram serving of soybeans is approximately 1.35.

​

The low GI of soybeans suggests they have a minimal effect on blood glucose levels, making them suitable for inclusion in a diabetes-friendly diet. The GI of soybeans remains low regardless of the cooking method, as their high protein and fiber content helps moderate the release of sugars into the bloodstream.² This characteristic is beneficial for blood sugar management and overall metabolic health.

Soybeans are highly nutritious, providing a rich source of protein, fiber, and essential nutrients. A 100-gram serving of boiled soybeans contains approximately 16 grams of protein and 6 grams of dietary fiber, and is a good source of vitamins and minerals, including iron, calcium, and B vitamins.² Their high protein content and beneficial fats make them excellent for supporting muscle health and overall nutritional balance.²

Soybeans can be an effective component of a weight loss diet due to their high protein and fiber content, which helps promote satiety and reduce overall calorie intake. A 100-gram serving of boiled soybeans contains about 16 grams of protein and 6 grams of fiber, both of which contribute to a feeling of fullness and can help manage appetite.² High-protein foods like soybeans can also support muscle maintenance, which is crucial for a healthy metabolism during weight loss.

​

Moreover, soybeans have a low glycemic index (GI) of approximately 15, which means they have a minimal impact on blood sugar levels and can help prevent blood sugar spikes that often lead to increased hunger and overeating. Unlike some weight loss foods that may be low in nutrients, soybeans provide essential vitamins and minerals while supporting weight management through their balanced macronutrient profile.

Soybeans can be a safe and beneficial food choice for individuals with diabetes. Their low glycemic index (GI) of approximately 15 indicates that they have a minimal impact on blood sugar levels.¹ This low GI, combined with their high protein and fiber content, helps to stabilize blood sugar and control appetite, making soybeans a valuable addition to a diabetes-friendly diet.²

​

Beyond their GI, soybeans offer additional advantages for diabetes management. They contain compounds called isoflavones, which may have beneficial effects on insulin sensitivity and inflammation. This makes soybeans not only a low-GI food but also one that supports overall metabolic health, which is essential for managing diabetes effectively.

Allergies to soybeans are relatively common, particularly in children, and can cause a range of symptoms, from mild hives to severe anaphylaxis. Soybean allergy is often associated with other legume allergies and can sometimes persist into adulthood. Unlike some other allergens, soybeans are present in many processed foods, making it challenging for individuals with allergies to avoid exposure.
