In today’s world, where health issues like diabetes, weight gain and poor digestion are becoming more and more common, the food we eat plays a bigger role than ever. Many different diets and trends come and go, but one diet plan that has scientific backing is supporting a diet that is high in fiber and low in glycemic index (GI) foods.
These types of food are beneficial on many levels. They keep you full for longer, they do not cause a sugar spike, they allow food to digest smoothly and raise your overall energy levels. High fiber and low GI foods are particularly valuable for people dealing with pre-existing conditions such as diabetes, PCOS, heart issues or obesity, but serve a greater range of people who simply want to mindfully eat for better health in the long term.
The good news is that you can greatly benefit from eating these foods without following a separate or expensive diet plan. Many of these commodities are simply commonly available in a regular market, they are high in fiber and low GI already, we just need to identify those foods and consume them more wisely.
What Is Fiber?
To better understand this topic, let’s start with the basics. Fiber is a type of carbohydrate that your body cannot entirely digest. Unlike other carbohydrates which break down into sugar, fiber travels through your entire digestive system and essentially cleans it out, as well as slows sugar from other food sources from entering your blood.
There are two basic forms of fiber:
- Soluble fiber – Fibers that dissolve in water and helps with blood sugar control, and keeps cholesterol levels lower (examples are oats, fruit, and dal).
- Insoluble fiber – Fibers that bulk up your stool and help prevent constipation (examples are vegetables, whole grain foods, and leafy greens).
According to the Indian Council of Medical Research (ICMR), the recommended dietary fiber intake for adults is 25 to 40 grams, but many do not achieve this.
What is glycemic index (GI)?
The glycemic index is a ranking system designed to indicate how rapidly and how high a food raises your blood sugar after consumption. The scale from low to high runs from 0-100.
- Low GI (55 or less): Slow rise in blood sugar – that’s good stuff.
- Medium GI (56-69): Moderate rise in blood sugar levels.
- High GI (70 or more): Fast rise – not as ideal for regular consumption.
When you eat foods that are low on the glycemic index, they tend to leave us feeling fuller longer and will not lead to blood sugar spikes or sudden decrease in energy levels. According to the University of Sydney’s Glycemic Index Research, low GI diets lower the risk of developing type 2 diabetes and provide improved blood sugar control for individuals who have already been diagnosed with diabetes.
Benefits of high-fiber, low-GI foods
High-fiber, low-glycemic index foods are often recommended by nutritionists and medical experts because of their long-term effects on metabolism and digestion.
Key Benefits

What to Eat: 10 Indian Foods That Are High in Fiber and Low in Glycemic Index
1. Moong Dal (Whole Green Gram)
GI & Fiber: 38 GI | 8g fiber per 100g
Usage: Typically sprouted as a salad component, cooked as dal, incorporated into khichdi, or into dosa batter. Sprouting or a boil increases the effectiveness of it and allows an easy digestion. But deep-frying into ‘pakoras’ definitely acts negative.
2. Rajma (Kidney Beans)
GI & Fiber: 29 GI | 6.4g fiber per 100g
Usage: Popularly consumed in onions-tomato gravies, paired with rice. Rajma itself is high fibre, slow digesting, but large quantities of white rice increase the glycemic load. Most definitely the best option is combined with brown rice or eaten in small portions of rice.
3. Chickpeas (Kabuli Chana)
GI & Fiber: 28-33 GI | 12.5g fiber per 100g
Usage: Commonly a part of chole, boiled salads, chaats and roasted snacks. All excellent and healthy use, except when they are soaked in oily gravies. Besan (chickpea flour) is also good for you, but limit the deep-fried pakora or sweet versions and try more ‘chillas’.
4. Ragi (Finger Millet)
GI & Fiber: 54 GI | 11-12g fiber per 100g
Usage: Prepared as a roti, roti malt (porridge), as dosa, or as snacks. All traditional ways of eating ragi were appropriate. Just don’t have sweetened roti malt or high-sugar level ragi cookies if you are diabetic.
5.Bajra (Pearl Millet)
GI & Fiber: 55 GI | 11.5g fiber per 100g
Usage: Popular in rotis, khichdi and laddoos. Roti with bajra is a better option in controlling blood sugar. Bajra-based desserts or overuse in peak summer may not be for everyone.
6. Barely (Jau)
GI & Fiber: 25 GI | 17.3g fiber per 100g
Usage: Made to use in barley water, in soups and as rice. Good for blood sugar and digestion. Do not consume barley drinks that are found in stores or too bitter.
7. Brown Rice
GI & Fiber: 50-55 GI, 2.5g fiber per 100g
Usage: Swapped in for white rice in a meal, for making a pulao or fermented to make idli/dosa batter. A great switch so long as you cook it properly, do not over steam, and serve with dals or vegetables. Avoid steaming into a mush, which easily digests and raises GI.
8. Sweet Potatoes
GI & Fiber: 44-55 GI (boiled), 3g fiber per 100g
Usage: Eaten boiled, roasted, in chaats and in sabzis. These are good eating methods for sweet potatoes. Fried shakarkand, or sweet/shakkar-coated shakarkand, reduces its value.
9. Apple (with skin)
GI & Fiber: 36 GI, 2.4g fiber per 100g
Usage: Usually eaten raw, or are added in salads and smoothies. Eating with the skin is very important, as you will be missing most of the fiber benefits by peeling it.
10. Spinach & Leafy Greens (Palak, Methi, Chaulai)
GI & Fiber: Very low GI | 2.2g fiber per 100g (cooked)
Usage: Used in dals, saag, parathas and curries. Excellent as long as it is not overcooked or deep-fried. Light sautéing or steaming keeps the fiber and nutrients intact.
Conclusion
Low glycemic index, high fiber foods are more than something very medical sounding to just hear, they are daily catalysts to promote better health. Many times their effects drive our choices in foods. If we eat food that digests slowly and maintains natural blood sugar levels, we can usually avoid other health problems. These foods will generally help those with diabetes, PCOS, weight loss concerns, digestive complaints, and heart health. This way of eating can generally be positive for everyone; from children to seniors. It offers a way to health that is long-term and has not relied on overpriced solutions and diets.
More importantly, the greatest sources of high fiber, low-GI foods come from commonly known Indian household items – dals, millets, legumes, fruits, and vegetables. Just a small change from regular rice to brown ones or a bit of quantity difference can take you a long way. Most of these grains and plants are also known to many cultures beyond India.
Understand these foods better, use them in their proper forms and incorporate them more often. And visibly notice internal as well as physical change.
