Your daily food choices can quietly move you closer to diabetes. A diabetologist shares six common foods to avoid if you have prediabetes.
Prediabetes is often referred to as a silent warning sign of diabetes. It means that your blood sugar level is higher than normal, but not high enough to be diagnosed with type 2 diabetes. This phase is reversible with the right lifestyle and dietary changes. Globally, diabetes is increasing at an alarming rate, affecting nearly 589 million adults in 2024, and this number is expected to reach 853 million by 2050. What you eat plays an important role in controlling blood sugar levels.
According to Dr. Aarti Ullalphysician and diabetologist at Gleneagles Hospital Parel, making conscious nutritional choices can help prevent or slow the progression of prediabetes. Avoiding certain foods that cause sudden spikes is an important step toward better health.
What is prediabetes and why is nutrition important?
Prediabetes occurs when the body begins to struggle with insulin, leading to higher-than-normal blood sugar levels. If not treated, it can gradually turn into type 2 diabetes. Diet plays a crucial role as certain foods can cause rapid spikes in blood sugar levels, worsening the condition over time. Dr. Ullal explains that managing prediabetes is less about strict diets and more about avoiding foods that disrupt blood sugar levels.
Foods to avoid with prediabetes
Here are 6 foods to avoid if you have been diagnosed with prediabetes:
1. Sugary drinks and sweets
Sugary foods are one of the biggest triggers for blood sugar spikes. Sodas, packaged juices, sweets, sweets, baked goods and desserts contain large amounts of added sugar. A study published in Nature Reviews Endocrinology suggests that reducing sugar intake can help lower blood sugar levels and lower sugar levels risk of fatty liver disease.
The American Heart Association recommends limiting added sugar to 25 grams per day for women and 36 grams for men. Even items like sweetened breakfast cereals, flavored coffee and sugary sauces should be avoided.
2. Refined carbohydrates
“Refined carbohydrates such as white bread, white rice and maida-based foods (such as naan, pasta, biscuits and cakes) are low in fiber and are digested quickly. This leads to a rapid rise in blood sugar levels,” says Dr Ullal.
According to the American Journal of Clinical NutritionHigh glycemic index (GI) foods can cause sharp spikes in glucose levels. Instead, choose whole grains such as brown rice, oats, quinoa and barley, which release sugar more slowly into the bloodstream.
3. Fried and fast food
Foods such as chips, fries, samosas and burgers contain a lot of unhealthy fats and calories. These can worsen insulin resistance, making it harder for your body to effectively manage blood sugar levels. Dr. Ullal emphasizes that limiting such foods is not only essential for blood sugar control, but also for overall metabolic health.
4. Processed and packaged foods
Ready-made meals, packaged snacks and cookies often contain hidden sugars, unhealthy fats and too much salt. These ingredients can silently increase blood sugar levels and affect overall health. Reading labels and choosing fresh, home-cooked meals is a better approach.
5. Sugary fruits and dried fruits
Fruits are healthy, but some, such as mangoes, grapes and bananas, are naturally high in sugar and should be consumed in moderation if you have prediabetes. Dried fruit is even more concentrated in sugar because the water content is removed. Some also added sugar during processing, which can increase further blood sugar levels.

6. Alcohol
Alcohol can disrupt your liver’s ability to regulate blood sugar levels. It can also interact with medications such as metformin. A study published in StatPearls emphasizes that alcohol consumption can affect glucose metabolism, making blood sugar control more difficult.
Like Dr. Ullal advises, consistent small changes in your diet can help you take control of your health and prevent diabetes in the long term!
Related FAQs
Can prediabetes be reversed with diet alone?
Yes, in many cases prediabetes can be reversed with the right diet and lifestyle changes. Eating well-balanced meals, avoiding sugary and refined foods, staying active and maintaining a healthy weight can help return blood sugar levels to normal.
Is it okay to eat rice if you have prediabetes?
Yes, but the type and portion are important. White rice can spike blood sugar levels quickly, so it’s better to switch to brown rice or other whole grains like quinoa or oats. Combining rice with protein and fiber can also help control sugar levels.
What fruits are safe to eat with prediabetes?
Low to moderate glycemic fruits such as apples, pears, berries, oranges and guava are generally safer options. They release sugar slowly and are rich in fiber. However, portion control is important, even with healthy fruits.
Can Skipping Meals Control Blood Sugar in Prediabetes?
No, skipping meals can actually lead to unstable blood sugar levels and overeating later. It is better to eat small, balanced meals at regular intervals to keep blood sugar levels stable throughout the day.
