Glycemic Index: Chart, Low Glycemic Foods and Diet and How to Use It
What is the Glycemic Index? The glycemic index (GI) measures how various foods affect blood sugar levels. Food items are ranked on a scale of 0-100 based on their impact on blood glucose. In simple terms, foods with a high glycemic index cause rapid spikes in blood sugar levels, while those with low glycemic index have lesser impact. Here’s a quick breakdown of glycemic index ratings: Low: 55 or less Medium: 56–69 High: 70 or above Foods that contain no carbohydrates such as meat, fish, poultry, nuts, seeds, herbs, spices, and oils are not assigned a glycemic index value. It's important to note that factors like nutrient composition, cooking method, and ripeness of fruits and vegetables also affect glycemic index value. How is the Glycemic Index Determined? Several factors influence the glycemic index of a food. These include: Nutrient Composition: Foods that are high in refined carbohydrates and sugar are digested rapidly, resulting in a high glycemic index. In contrast, foods that are rich in protein, fat, or fiber generally have a low glycemic index. Cooking Method: The way you cook your food can influence its glycemic index. For instance, boiling potatoes increases their glycemic index compared to baking or roasting. Ripeness and Processing: The ripeness of fruits and vegetables can influence their glycemic index. Generally, more ripe or processed foods have a higher glycemic index compared to those that are less ripe or unprocessed. Remember, the glycemic index is not the same as the glycemic load (GL). GL considers not just the type of carbohydrates in the food but also the quantity consumed, offering a more realistic indication of how it may affect blood sugar levels. What is a Low Glycemic Diet? A low glycemic diet involves choosing foods with a low glycemic index over those with a high glycemic index. Following this diet can be particularly beneficial for people with diabetes or those trying to lose weight. Here's why: Improved blood sugar regulation: A low glycemic diet helps regulate blood sugar levels, reducing the risk of sudden spikes and crashes. Increased weight loss: Several studies suggest that sticking to low glycemic foods can support short-term weight loss. Benefits for people with fatty liver disease: A low glycemic diet may reduce liver fat and liver enzyme levels in people with non-alcoholic fatty liver disease. Benefits of a Low Glycemic Index Diet Making the switch to a low glycemic diet comes decked with numerous benefits: Better Blood Sugar Control: A low glycemic diet helps maintain balanced blood sugar levels, reducing instances of hypoglycemia and hyperglycemia. Weight Management: This diet promotes satiety, thereby aiding in weight management. Heart Health: Consuming low glycemic foods has been linked to a decreased risk of heart disease. Reduced Insulin Resistance: A low-GI diet may reduce insulin resistance, a crucial factor in developing type II diabetes and PCOS. Improved Digestive Health: Foods with low glycemic index often contain more fibre, promoting better digestive health. Indian Foods with Low Glycemic Index If you're considering a low glycemic diet, here are some Indian foods to include in your regimen: Cereals and Grains: Whole wheat, brown rice, quinoa Fruits: Apples, oranges, peaches Vegetables: Spinach, broccoli, bell peppers Legumes: Lentils, chickpeas, kidney beans Nuts and Seeds: Almonds, walnuts, flax seeds Indian Foods with High Glycemic Index While adopting a low glycemic diet, limit the consumption of Indian foods with a high glycemic index like: White rice Instant oatmeal White bread Cornflakes Potatoes Watermelon Jaggery Pumpkin Indian Foods with Moderate Glycemic Index Certain Indian foods have a moderate glycemic index and can be consumed in moderation: Bananas Pineapples Sweet corn Beets Glycemic Index (GI) Chart Here is a comprehensive glycemic index chart with low, medium, and high glycemic index foods: Low Glycemic Index Foods (GI ≤ 55) Fruits Apple, Grapefruit, Orange, Pear, Peach, Plum, Strawberries Vegetables Broccoli, Carrot, Cauliflower, Eggplant, Lettuce, Spinach, Tomatoes Grains Barley, Bulgur, Steel-cut oats, Quinoa, Brown rice, Whole wheat bread Legumes Lentils, Kidney beans, Chickpeas, Black beans Dairy Milk, Yogurt, Cheese Nuts and Seeds Peanuts, Almonds, Walnuts, Flaxseeds, Chia seeds Medium Glycemic Index Foods (GI 56-69) Fruits Bananas, Raisins, Pineapple, Mango Vegetables Russet potatoes, Sweet potatoes Grains Whole wheat pasta, Basmati rice, Couscous Legume-related foods Hummus High Glycemic Index Foods (GI ≥ 70) Grains White bread, Cornflakes, Rice cakes, Pretzels Sweets Jelly beans, Gummy bears, Candy bars, Cookies, Cakes Snacks Potato chips, French fries, Crackers, Fried Farsans Beverages Packed fruit juices, Soda, Sports drinks FAQs How can I calculate the glycemic index of packaged food? Calculating the glycemic index of packaged foods involves some simple maths. Look at the nutrition facts label on your food package and find out the amount of carbohydrates it contains per serving. Then use the GI value of that specific food (you can find this by searching "glycemic index of [name of food]" online). Now, multiply this GI value by the number of grams of carbohydrate per serving and divide by 100. This will give you an estimate of how much this particular serving will raise your blood sugar compared to eating pure glucose. What are the benefits of having a diet rich in low glycemic index food? Eating foods with a low glycemic index can lead to many health benefits: Improved diabetes control: Low glycemic index foods are broken down more slowly, resulting in a gradual and steady release of glucose into the bloodstream. This can help manage blood glucose levels and prevent spikes. Better weight management: Foods with a low glycemic index tend to keep you feeling full for longer, reducing the chance of overeating and aiding in weight management. Reduced risk of heart disease: A diet rich in low glycemic index foods can help lower cholesterol levels, thus reducing the risk of heart disease. Enhanced physical endurance: Consuming low glycemic index meals a few hours before long-distance running or other endurance events can improving the exercise capacity. How can I include low glycemic index food in my diet? Integrating low glycemic foods into your diet can be relatively straightforward: Choose whole grains: Whole-grain bread, brown rice, and oats have lower glycemic index values compared to their refined counterparts. Include more fruits and vegetables: Most non-starchy vegetables and fruits have a low glycemic index. Opt for legumes: Foods like beans, chickpeas, and lentils have very low GIs. Incorporate lean proteins: Fish, chicken, eggs, and lean meat have minimal effect on blood glucose levels. Conclusion Keep in mind that balance is crucial—it’s not always necessary or feasible to choose only low glycemic index foods. Combining a high GI food with a low GI option can lead to an intermediate GI for that meal. Using a glycemic index chart or the glycemic index food chart can be powerful tools in managing your health, whether for diabetes control, weight management, or overall wellness.

What is Glycemic Index: Low vs High Glycemic Foods and How to Use It
Introduction Throughout the day, your blood sugar levels undergo various ups and downs based on the food you eat. The glycemic index is a scale from zero to 100 that assigns a numeric score for food, usually depending on how drastically it can cause your blood sugar to rise. Pure glucose is given a value of 100, and all other foods are compared to this before being assigned a value. A glycemic index is a beneficial tool for better blood sugar management. Using this helps you gain better awareness about what is on your plate and helps you in your weight loss journey, reduce your cholesterol levels, and lower your blood sugar levels. Find out more about the glycemic index, its effect on your health, and how best to use it daily. What is the glycemic index? The glycemic index (GI) measures how different foods affect your blood sugar. The food is usually classified as high, medium, and low and is ranked on a scale of 0 to 100. The lower the glycemic index of an item, the less it will affect your blood sugar levels. Here is how to identify which category, based on glycemic index, a specific food may fall under. Low: 55 GI rating or less Medium: 56-69 GI rating High: 70 or above GI rating When you consume food close to how they are found in nature, it will have a lower glycemic index than foods that have undergone high levels of processing. Processed foods usually have a higher glycemic index. Most packages list their glycemic index on their labels, or you can also find the glycemic index for common foodstuffs on the internet. Examples of high glycemic index foods Carbohydrates usually get broken down very quickly in the body and can cause a rapid increase in your blood glucose levels. That is why they have higher GI than other foods. Some examples of high-GI foods are Sugar and other sugary food Sugary soft drinks and aerated drinks Potatoes White rice White bread Examples of low glycemic index foods Those foods that are broken down slowly cause your blood sugar levels to rise gradually over time. Examples of these foods are Certain fruits and vegetables Wholegrains like porridge oats Pulses Changes in glycemic index The number you see as the glycemic index for different foods is usually the starting point value. These values could change before the item hits your plate. This change depends on several factors, such as: Preparation Acid, fat, and fibre can help lower the food's glycemic index. On the other hand, the longer you cook starches such as pasta, the higher their glycemic index will rise. Ripeness Some fruits, like the banana, will show a higher glycemic index as they ripen. Foods Eaten Together You can bring the overall glycemic index of the meal by combining foods with higher glycemic index and those with lower values. Other factors that affect the food's glycemic index depend on the person consuming the meal. How active you are, your age and the speed at which you digest your food are also important parameters when considering your body's reaction to carbs. If you are diagnosed with gastroparesis, a complication of diabetes, it can further delay the emptying of your stomach and result in slower absorption of food. How to use glycemic index to help control blood sugar? The glycemic index is one strategy that can help control your blood sugar levels. This is especially useful if you have diabetes or want to lose weight. A low glycemic index diet's significant benefits include lower risks of heart disease, cancer, and other conditions. Here is how you can reap the benefits of using the glycemic index while planning your meals: Compare carbs Carbohydrates are one of the primary nutrients in rice, vegetables, fruits, cereals, and dairy. Simple carbs usually comprise linked sugar molecules like sucrose, glucose, and fructose. On the other hand, starches like corn, potatoes, wheat, etc., consist of multiple glucose molecules strung together in a long chain. The glycemic index helps you understand which carbs are more likely to promote a spike in your blood sugar levels and which ones can cause a gradual increase. Choosing a healthier diet Using the glycemic index to create a healthy diet plan is easy. All you have to do is swap out foods with high glycemic index with low glycemic index foods. While researchers have created a glycemic index chart with thousands of foods, here are some common foods based on their glycemic index: Low glycemic index foods: Fruits, vegetables, beans, minimally processed grains, low-fat dairy food, nuts, and pasta. Moderate glycemic index foods: White potatoes, sweet potatoes, white rice, corn, cous cous, and wheat-based breakfast cereals. High glycemic index: Rice cakes, crackers, most packaged breakfast cereals, bagels, doughnuts, cakes, waffles, croissants, and cookies. Planning your diet Spend some time every week planning your diet and finding low glycemic index alternatives to your favourite foods using the glycemic index. You will start seeing positive changes in your health and fitness levels. Book a Blood Test Conclusion The glycemic index is a tool that helps individuals make healthy diet choices. If you are diagnosed with lifestyle diseases like diabetes, obesity or are at risk of heart disease, you can reap many benefits from switching to a low glycemic index diet. However, the benefits of a low glycemic index diet extend far beyond those with chronic illnesses. This is why along with changing your dietary habits, you also need to undergo regular medical checkups to keep track of your health and know if there are any changes in your situation.
