Have you ever thought of the food that could lead to a drastic blood sugar spike? However, what if you could eat food that made you happy without experiencing a drastic spike? A bowl of rice or mashed potatoes. All of these sound nice. But, at the cost of what?However, Dr Terry Shintani, MD, and a Harvard-trained nutritionist who has a following of over 250K on his social media accounts is here to save you! He says you can have your carbs and eat it guilt free. He has shared a simple method that could cut down the glycemic index (GI) of common carbohydrates down by 50%. He claims that it could potentially transform how people manage blood sugar and overall health. But, before we get into the method he shared, let us first understand what glycemic index is?What Is Glycemic Index, How Does It Work?As per the National Cancer Institute, glycemic index is a measure of increase in the level of blood glucose, which is a type of sugar, that is caused by eating a specific carbohydrate, meaning the food that contains sugar, and compared with eating a standard amount of glucose. Foods with a high glycemic index release glucose quickly and cause a rapid rise in blood glucose. Foods with a low glycemic index release glucose slowly into the blood. The glycemic index also ranks the effect food has on blood sugar levels. A low-GI diet suggests foods that have low GI values. The categories are:Low GI: 1 to 55Medium GI: 56 to 69High GIL 70 or higherWhen you eat food that have carbohydrates, your digestive system breaks it down into simpler sugars and it enters your bloodstream. This can have an effect on your blood sugar. However, every food item has its own effect on blood sugar levels. For instance, if you have something sweet in the morning, then it can cause a sugar spike in your blood and leave you wanting to eat more carbs. High-Gi foods can trigger a quick insulin release to regulate glucose, and in turn, it could lead to an increased hunger, insulin resistance and risk of type 2 diabetes. Whereas low Gi-food can digest more slowly and reduce the risk of chronic diseases. What Does Dr Terry Shintani Say?Dr Terry has revealed a unique, but a very simple technique that can keep your GI levels in check, even while eating carbs like rice, bread, potatoes, and pasta. "Yes, you can cut the glycemic index of common carbs by as much as 50%."In a video he shared, he said, "Here's the secret to lowering the glycemic index of common carbs and it helps you control blood sugar. It is unbelievably simple. Just heat it and cool it," he said. He recommended that cooling the cooked rice in the fridge overnight and then reheating it will drop it GI levels from 78 down to 54. In case you want a toast int he morning, the best way is to freeze it and then toast it. He said that this process lowers the GI levels by 39%. "For potatoes, cooking, cooling, and reheating can reduce their glycemic index by 30 to 40%. And for pasta, chilling and reheating can cut the glycemic index by 50%."He explained, "The process of heating and cooling carbs causes a cross-linkage and restructuring of the starch, turning some of it into resistant starches. This slows the digestion of the starch and causes a slower release of sugar into the bloodstream. So, try this simple hack on your carbs to keep your blood sugar in check."
