Managing food choices with PCOS can feel like a puzzle. Which grains, which fruits, which snacks? One straightforward guide is the glycemic index (GI), a scale from 0 to 100 that shows how quickly a particular food raises blood sugar. Foods with a GI of 55 or below are considered low GI. Foods at 56 to 69 are medium GI. Foods at 70 or above are high GI.
The good news for Indian kitchens: most traditional dals, millets, and vegetables fall in the low-GI range. The challenge is knowing exactly where each food sits and how to build meals around the best options.
For why low-GI eating matters specifically for PCOS, read our complete guide to insulin resistance and PCOS. This post is the food side only: a category-by-category cheat sheet with GI values, practical swaps, a sample day, and two easy recipes.
GI values in this guide are sourced primarily from Atkinson, Foster-Powell and Brand-Miller (International Tables of GI and Glycemic Load Values, Diabetes Care 2008;31:2281-3) for grains, legumes, and most fruits. Indian-specific foods such as jamun and guava do not appear in the Atkinson 2008 global tables. GI values for these foods are drawn from published Indian clinical nutrition research. ICMR-NIN Nutritive Value of Indian Foods (2017) is the source for food composition data.
Low-GI Indian Grains
Indian cooking uses a wide range of grains and millets. Here is how the most common ones compare:
| Grain | GI (approx.) | How to use |
|---|---|---|
| Barley (jau), cooked | 25-28 | Add to soups, make jau kanji, mix into dalia |
| Broken wheat / dalia | 41-53 | Upma, khichdi, porridge with vegetables |
| Ragi / finger millet roti | 52-55 | Roti, mudde, dosa, ragi java. See our ragi guide |
| Brown rice, cooked | 50-55 | Use in smaller portions alongside dal |
| Rolled oats | 55-60 | Use whole rolled oats, not instant varieties |
| Whole wheat chapati | 52-62 | Stone-ground atta gives lower GI than refined |
| Bajra / pearl millet roti | 54-67 | GI varies by preparation. Roti is lower than porridge |
| Jowar / sorghum roti | 55-62 | See our jowar guide |
| White rice, cooked | 64-72 | Medium to high GI. Portion size and pairing matter |
| White bread / maida roti | 70+ | High GI. Swap out wherever possible |
Practical note: Millets like ragi, bajra, and jowar are traditional Indian staples that sit in the low-to-moderate GI range. If you want to shift your grain choices without cooking unfamiliar foods, millets are the easiest switch because they are already part of Indian food culture in most regions.
Barley (jau) is worth highlighting: at GI 25-28, it is one of the lowest-GI grains anywhere in the world and is inexpensive in Indian markets. Use it in soups and kanji if you have not tried it yet.
Low-GI Dals and Legumes
Indian dals and legumes are some of the lowest-GI foods available anywhere. Most fall between GI 8 and 45, well inside the low category.
| Dal or Legume | GI (approx.) | Serving idea |
|---|---|---|
| Chana dal | 8-11 | Dal tadka, chana dal khichdi, besan cheela |
| Masoor dal (red lentils) | 21-30 | Everyday dal, masoor soup |
| Rajma (red kidney beans) | 24-29 | Rajma rice, rajma curry, cold rajma salad |
| Kala chana (black chickpeas) | 28-35 | Sundal, sprouted kala chana chaat |
| Moong dal (split, yellow) | 29-38 | Khichdi, cheela, moong soup, halwa in small amounts |
| Lobia (cow peas) | 33 | Lobia curry, lobia salad, mixed dal |
| Kabuli chana (white chickpeas) | 28-36 | Chole, chaat base, hummus |
| Urad dal (whole black) | 43 | Idli batter, dal makhani, whole urad dal |
Two things to note. First, canned or pre-cooked legumes have similar GI to home-cooked ones, so convenience versions are fine. Second, soaking dals overnight before cooking slightly lowers their GI compared to using them straight from the packet. Rinsing soaked water and cooking fresh also improves digestibility.
For more on how to use dals daily, see our high-fibre Indian foods guide.
Low-GI Vegetables
Most non-starchy vegetables have a GI below 20. This means they can form the bulk of your plate without any concern about GI.
These vegetables can be eaten freely:
- Palak (spinach), methi (fenugreek leaves), bathua, amaranth
- Bhindi (okra), brinjal (baingan), tinda, turai (ridge gourd), ghia (lauki / bottle gourd)
- Tomato, capsicum, cucumber
- Karela (bitter gourd), French beans, val papdi (broad beans)
- Cabbage (patta gobhi), cauliflower (phool gobhi), broccoli
- Gajar (carrot), mooli (radish), beetroot
- Pyaaz (onion), lehsun (garlic), adrak (ginger)
Starchy vegetables to portion:
| Vegetable | GI | Notes |
|---|---|---|
| Sweet potato (shakarkandi) | 50-61 | 1 medium boiled (about 80-100g). Avoid frying |
| Regular potato | 78-85 | High GI. Use smaller portions and pair with dal |
| Corn / bhutta | 52-60 | 1 cob or a small serving. Not corn flour |
| Arbi (colocasia / taro) | 56-60 | At the low-to-medium boundary |
One useful technique: cooking potato or sweet potato and letting it cool before eating lowers GI slightly, because cooling forms resistant starch. This is why potato salad (cooled) has a lower GI than freshly boiled hot potato.
Low-GI Fruits
Whole fruits are almost always lower GI than their juices. The fibre in the skin and flesh slows sugar absorption, so eating an orange gives a different GI impact than drinking orange juice.
| Fruit | GI (approx.) | Portion |
|---|---|---|
| Guava (amrood) | 12-24 | 1-2 medium fruits, peel on |
| Jamun (Indian black plum) | 25 | 10-15 berries. In season, excellent daily choice |
| Apple | 38-40 | 1 medium, eaten with peel |
| Pear (nashpati) | 38 | 1 medium |
| Orange (narangi) | 43 | 1 medium, whole fruit not juice |
| Mosambi (sweet lime) | 43 | 1 medium |
| Banana | 51-55 | 1 small-to-medium. Slightly firmer bananas have lower GI than very ripe ones |
| Pomegranate (anar) | 53 | 1 small cup of seeds (about 100g) |
| Mango (ripe) | 41-60 | Varies by variety. About 100g (half a small kesar or alphonso) |
| Watermelon | 72-80 | High GI. Small portions only if you enjoy it |
| Grapes | 46-59 | Small portion of about 10-12 grapes |
A note on mango: The GI of mango varies significantly depending on variety and ripeness. Kesar, alphonso, and banganapalli in moderate portions (around 100g) tend to be on the lower end of the range. For a full seasonal mango guide with portion advice by trimester and life stage, see our mango during pregnancy post.
Smart Food Swaps
Small changes at each meal shift your daily plate toward lower GI without requiring unfamiliar recipes or expensive ingredients.
| Instead of | Choose | What changes |
|---|---|---|
| White rice (1 full cup) | 1/2 cup brown rice + 1 bajra or jowar roti | Cuts GI of the grain component significantly |
| Maida roti or stuffed paratha | Whole wheat chapati with stone-ground atta | Higher fibre, lower GI |
| Fruit juice (any variety) | Whole fruit | Juice removes fibre, raising GI sharply |
| Plain white rice kanji | Ragi kanji or dalia porridge with vegetables | Lower GI, more nutrients |
| White bread | Whole grain bread or no bread | Maida bread has one of the highest GIs of common foods |
| Snacking on namkeen or biscuits | Roasted chana, makhana, or a small handful of aakhrot | Low-GI, sustaining snacks |
| Deep-fried potato chips | Roasted sweet potato wedges | Lower GI and less oil |
| Instant oats | Rolled oats (soaked overnight) | Processing raises GI; whole rolled oats are better |
| Sweetened chai (2 teaspoons sugar) | Half-teaspoon sugar or no sugar, plain milk chai | Any added sugar raises the GI of the whole cup |
| Bottled juice or cola | Nimbu pani (no sugar) or plain chaas | No GI impact at all |
One note on jaggery: jaggery is not a low-GI sweetener. Its GI is approximately 84-86, which is similar to or higher than refined sugar (GI around 65). Jaggery does provide more minerals than refined sugar, but it should be used in small amounts when a recipe specifically calls for it, not as a replacement that can be used freely.

2 Low-GI Indian Recipes
Recipe 1: Bajra-Jowar Thalipeeth
A quick, filling, two-millet flatbread. Low GI, high fibre.
Ingredients (makes 3 rotis):
- 1/2 cup bajra atta (pearl millet flour)
- 1/2 cup jowar atta (sorghum flour)
- 2 tablespoons besan (chickpea flour)
- 1/4 cup finely chopped palak or methi leaves
- 1 tablespoon finely chopped onion
- 1/4 teaspoon jeera (cumin seeds)
- 1/4 teaspoon haldi (turmeric)
- Salt to taste
- Water to bind
Method:
- Combine all flours, haldi, jeera, and salt in a mixing bowl.
- Add the palak and onion. Mix well to distribute evenly.
- Add water in small amounts and bring the dough together. It should be soft but not sticky.
- Divide into 3 equal portions. Wet your palm slightly and pat each portion into a thin, flat circle on a piece of wet cloth or banana leaf. Millet dough does not roll well with a belan; pressing by hand or using damp cloth gives cleaner results.
- Cook on a hot tawa on medium flame for about 2 minutes each side until small brown spots appear and the roti is cooked through.
- Serve with plain dahi or green chutney.
Approx. per roti: 130 kcal, 4g protein, 2.5g fibre. Low GI.
Recipe 2: Chana Dal Palak
A thick, everyday dal using two of the lowest-GI foods in Indian cooking.
Ingredients (serves 2):
- 1/2 cup chana dal, washed and soaked for 30 minutes
- 1 large handful palak, roughly chopped
- 1 medium tomato, diced
- 1/2 onion, diced
- 1 teaspoon mustard seeds
- 1/2 teaspoon jeera
- 1/2 teaspoon haldi
- 1/2 teaspoon dhania (coriander) powder
- 1/4 teaspoon red chilli powder (optional)
- 1 teaspoon ghee or oil
- Salt to taste
- A small squeeze of lime at the end
Method:
- Pressure cook the soaked chana dal with 1.5 cups water for 3-4 whistles until soft. Set aside.
- Heat ghee in a pan. Add mustard seeds and jeera. Wait for them to splutter.
- Add onion and cook until translucent. Add tomato and cook until the raw smell goes and the tomato softens.
- Add haldi, dhania, and chilli. Mix for 30 seconds.
- Add the cooked chana dal with its water. Stir and bring to a gentle simmer. If the dal is too thick, add a little hot water.
- Add palak. Stir and cook for 2-3 minutes until the leaves wilt into the dal.
- Adjust salt. Add a small squeeze of lime before serving.
- Serve hot with bajra roti or a small portion of brown rice.
Approx. per serving: 180 kcal, 9g protein, 7g fibre. Very low GI (chana dal GI 8-11).
Frequently Asked Questions
1. Which Indian grain has the lowest GI?
Barley (jau) has the lowest GI among Indian grains, at approximately 25-28. It is followed by broken wheat (dalia) at 41-53 depending on preparation, and then ragi at around 52-55. All three are inexpensive and available in most Indian markets. If you are new to low-GI grain eating, dalia upma or khichdi is an easy starting point because the texture is familiar.
2. Is brown rice actually lower GI than white rice?
Yes. Brown rice has a GI of approximately 50-55, while white rice ranges from 64 to 72 depending on variety and cooking method. The bran layer in brown rice slows digestion. That said, the difference is not dramatic enough to make brown rice a food you can eat in unlimited quantities. A moderate portion of brown rice alongside plenty of dal, vegetables, and dahi gives a better overall glycemic response than a large bowl of brown rice on its own.
3. Are all fruits high GI?
No. Most common Indian fruits are low to medium GI when eaten whole: guava (12-24), jamun (25), apple (38-40), pear (38), orange (43), and mosambi (43) are all well below 55. Watermelon is the main exception at GI 72-80. Eating fruit as whole fruit rather than juice consistently gives a lower GI response because the natural fibre in the flesh and skin slows absorption.
4. What is a good low-GI snack for managing PCOS through food?
Roasted chana is one of the best snack choices available: easy to carry, filling, and very low GI. Makhana (fox nuts) is another option that is commonly available and simple to roast at home with a little rock salt. A small handful of aakhrot (walnuts), or a cup of plain dahi with a whole fruit, also works well. Avoid packaged snacks labelled as healthy, as many contain maida, added sugar, or refined starch.
5. Does cooking method change the GI of a food?
Yes, noticeably for some foods. Slightly undercooked (al dente) grains have lower GI than fully soft-cooked versions because the starch granules have not broken down completely. Cooling cooked rice or potato before eating lowers GI by forming resistant starch. This is why cold cooked rice in a salad has a lower GI than hot freshly cooked rice. Roti made from stone-ground whole wheat atta also has lower GI than one made from maida, because the fibre in whole grain flour slows digestion.
6. Is jaggery (gur) a good substitute for sugar when eating low-GI?
Not in the way many people assume. Jaggery has a GI of approximately 84-86, which is higher than refined white sugar (GI around 65). It does contain more minerals than refined sugar, including iron, calcium, and potassium, which is why it is preferred in traditional recipes. But jaggery raises blood sugar quickly, so it is not a food you can use freely. Use a small amount when a recipe specifically needs sweetness, rather than replacing sugar gram-for-gram with jaggery.
7. I have PCOS. Do I need to cut out rice completely?
No. Portion size and pairing matter significantly. A small serving of white rice (about 1/2 cup cooked) eaten alongside a full serving of dal, plenty of vegetables, and a small cup of dahi slows the overall glycemic response of the meal because protein, fat, and fibre from the other foods moderate how quickly the rice is absorbed. Cutting portion size and pairing white rice well is a reasonable approach. If you want to go further, replacing some white rice meals with bajra roti, ragi mudde, or brown rice will shift your daily glycemic load noticeably without eliminating rice entirely.
Building a low-GI plate is not complicated once you know where each food sits. Most Indian kitchens already have the right ingredients: dals, millets, whole vegetables, and seasonal fruits. The practical step is combining them in the right proportions at each meal.
