Sweet Potato's Glycemic Index (GI) and Management Methods

Hello everyone! Today, we're going to talk about a beloved national snack, sweet potato. While sweet potatoes are known for being healthy and good for diets, those with diabetes or managing their weight might wonder if it's okay to eat them. So, today, we'll compare the GI (Glycemic Index) of sweet potatoes and discuss how to consume them healthily.

Sweet Potato's GI: Differences Based on Cooking Method

Did you know that the glycemic index of sweet potatoes can vary significantly depending on how they are cooked? This is because, even with the same sweet potato, the rate at which starch converts to sugar changes with the cooking method. Here's a breakdown of the GI based on different cooking methods:

• Raw Sweet Potato (GI 45-48): Characterized by its crisp texture, it has a low glycemic index.
• Steamed/Boiled Sweet Potato (GI 45-50): Cooked quickly with moisture, resulting in a low glycemic index.
• Baked Sweet Potato (GI 80-90): The glycemic index rises sharply due to prolonged baking.

As you can see, the glycemic index of sweet potatoes changes with the cooking method, making it very important to consider how you consume them.

Actual Consumption and Glycemic Load

Sweet potatoes are dense in texture and high in carbohydrates. A medium-sized steamed sweet potato (about 100-140g) contains approximately 26-30g of carbohydrates. Therefore, consuming a large amount of sweet potato can increase the glycemic load (GL). For steamed sweet potatoes, the glycemic load (GL) falls into the medium category, ranging from 11-18. It's best to approach sweet potatoes as a 'staple food instead of rice' rather than a 'fruit you can eat instead of water'.

How to Eat Sweet Potatoes to Prevent Blood Sugar Spikes

So, what are the best ways to consume sweet potatoes healthily? Remember these three tips!

• Turn them into Cold Sweet Potatoes: After boiling or steaming, refrigerate them for 1-2 hours to cool down before eating. This converts some starch into resistant starch, which can help moderate blood sugar rise.
• Eat Them with the Skin On and Chew Thoroughly: The skin of sweet potatoes is rich in dietary fiber and antioxidants that help slow down blood sugar increases.
• Pair Them with Protein and Healthy Fats: Instead of eating sweet potatoes alone, try consuming them with foods like boiled eggs or yogurt. This can help slow down the rate at which your blood sugar rises.
