Foods with High Glycemic Index and What to avoid: A Smart Eating Guide
Have you ever noticed how a sugary doughnut makes you feel energetic and then suddenly tired, but oatmeal keeps you going strong for a long time? Or how eating a lot of white rice can make you feel all over the place, but brown rice doesn’t?
This all comes down to something called the Glycemic Index (GI), and it’s changing how we look at food.
The Glycemic Index (GI) measures carbohydrates on a scale of 0 to 100. It ranks them based on how much they raise blood sugar levels after consumption.
Foods with high glycemic index (GI) are rapidly digested and absorbed, which causes a quick spike in blood sugar levels. Conversely, foods with a low GI release sugar slowly and steadily, which helps to minimize blood sugar spikes.
Here, we take a deep dive into foods with a high glycemic index and discuss which ones to avoid for smarter eating habits.
Understanding the Glycemic Index
- The Glycemic Index is a ranking system of food’s carbohydrate content based on its immediate effect on blood glucose levels.
- Carbohydrates, often called carbs, are one of the main types of nutrients in our diet. They are important because they are a major energy source for our body.
- Carbohydrates that break down quickly during digestion have the highest GIs. Their rapid digestion leads to marked fluctuations in blood sugar levels.
GI Classification
- High GI (70 and above): These foods cause a rapid rise in blood glucose levels. They are typically processed or refined foods with less fiber. Eg, white rice, white bread, sugary drinks, etc.
- Medium GI (56-69): These foods have a moderate effect on blood sugar. E.g., mangoes, bananas, raw pineapple, etc.
- Low GI (55 or less): These foods are slow to digest and absorb, causing a slower and smaller rise in blood sugar levels. E.g., seeds, nuts, leafy vegetables etc.
The GI value of food is affected by several factors, including the type of sugar it contains, its nutrient composition (amount of protein and fat), and the cooking method. The cooking method can transform the same food from low GI to medium GI or high GI.
Effects of High-Glycemic Index Foods
Consuming high-GI foods can cause your blood sugar levels to go up and down, which is particularly problematic for individuals with diabetes. These foods can also lead to weight gain and, if eaten in excess, are linked to various health problems.

The Impact of Cooking on GI
Preparing and cooking methods of our food can significantly alter the food’s GI. Let’s look at some common examples:
1. Potatoes
Raw potatoes have a moderate GI. However, boiling them raises their GI and becomes high GI as the heat breaks down the starches into simpler sugars. Surprisingly, frying potatoes lowers their GI due to the fat from the oil slowing down digestion.
2. Rice
The GI of rice varies with type and cooking method. Basmati rice, a staple in Indian cuisine, has a lower GI compared to other white rice types. Overcooking rice can increase its GI as it becomes softer and easier to digest.
3. Milk vs. Ice Cream
Milk has a low to moderate GI. Surprisingly, despite its high sugar content, ice cream has a lower GI because of its fat content, which slows down sugar absorption.

Notes:
- The GI values are approximate and can vary based on preparation methods, ingredients, and individual body responses.
- The GI of fruits can change significantly with ripeness and variety.
- Traditional Indian sweets typically have a moderate GI due to the high sugar and fat content (except jalebi, which has a high GI).
- Whole grains and legumes are generally lower in GI and are healthier options.
Smart Eating Strategies
1. Choose Low to Medium GI Foods
Opt for whole grains, legumes, and plenty of fresh fruits and vegetables. These foods are lower in GI and packed with essential nutrients.
2. Read Labels
Pay attention to food labels’ ingredients and nutritional information. Look for products with whole grains and fewer added sugars.
3. Balance Your Plate
Combine high-GI foods with low-GI foods to balance the meal and mitigate the blood sugar spike. For example, pair a piece of white bread with a hearty serving of vegetables and lean protein.
4. Monitor Portion Sizes
Even low-GI foods can lead to weight gain and higher blood sugar if consumed in large quantities. Be mindful of portion sizes and total carbohydrate intake.
