Last month, a customer messaged us asking for advice. Her nutritionist had told her to avoid watermelon because it has a "high glycemic index of 72." Scary number. So she'd cut out watermelon entirely — while continuing to add jaggery to her chai every morning because "it's natural and healthier than sugar."

Here's the irony: watermelon, the fruit she gave up, has a glycemic load of just 7.9. Meanwhile, jaggery — the "healthy" alternative she trusted — has a GI of 84, which is higher than the white sugar it's supposed to replace. Her post-meal glucose readings never improved. And she couldn't figure out why.

This is the GI trap. And millions of Indians fall into it every day — making food choices based on half the information, because nobody explained the other half.

That other half is called glycemic load. And once you understand it, the way you look at rice, roti, fruit, and even "natural" sweeteners like jaggery will change forever.

What Glycemic Index Actually Tells You (and What It Doesn't)

The glycemic index is a ranking system that measures how quickly a food raises your blood sugar, scored on a scale of 0 to 100 relative to pure glucose. It's been around since the early 1980s, and it's genuinely useful — as far as it goes.

For Indian foods, this gives us some useful signposts. White rice scores around 73 (high), chapati around 62 (medium), basmati rice 58 (medium), and most dals land at 29–35 (low). So far, so helpful.

But here's the critical flaw: GI is measured on a fixed 50-gram carbohydrate portion. Not a real serving. Not what you'd actually put on your plate. A standardised lab portion. To get 50 grams of carbohydrates from watermelon, you'd need to eat over four cups of it. Nobody does that in one sitting. But the GI score doesn't care — it treats watermelon as if you did.

This is why GI alone is dangerously incomplete. It tells you how fast a food can spike your blood sugar, but says nothing about how much it actually will in the amount you eat.

Glycemic Load: The Missing Half of the Equation

Glycemic load fixes this by factoring in both the quality and quantity of carbohydrates you actually consume. The formula is simple:

Now let's resolve the watermelon paradox. Watermelon has a GI of 72 — high. But one cup of watermelon contains only about 11 grams of carbohydrates. Its GL? Just 7.9. That's low. In a real portion, watermelon barely moves your blood sugar.

This changes the picture on dozens of Indian foods. Here's a reference table I've put together using values from the Indian Council of Medical Research, the Madras Diabetes Research Foundation, and Harvard Medical School's GI database. Save this one — it's worth coming back to.

The Jaggery Myth: Why "Natural" Doesn't Mean "Safe"

I want to spend a moment on jaggery, because it is perhaps the most protected myth in Indian nutrition. Every household uses it. Every grandmother swears by it. And the pitch has been repeated so often it feels like fact: "it's natural, it's unrefined, it has minerals, it's better than sugar."

Let's look at what a typical 20-gram piece of jaggery actually contains:

Now think about how jaggery is actually consumed. Two pieces in your morning chai (40g of jaggery = 38 grams of sugar). A piece after lunch "for digestion." A lump melted into til-gur laddoos in winter. Before you know it, you're consuming 60–80 grams of jaggery a day — that's 58–76 grams of pure sugar with a GI that's 29% higher than the white sugar you thought you were avoiding. The glycemic load of a 50g serving of jaggery is around 41 — higher than a cup of white rice.

Am I saying never eat jaggery? Not quite. If you genuinely enjoy the flavour of gur in a winter sweet or a festival recipe, a small amount as an occasional seasonal indulgence is human and fine. What I am saying is: stop treating it as medicine or a health food. It is not a digestive aid. It is not a meaningful source of iron. It is not "better" for your blood sugar. It is sugar — with a GI that's actually worse than the refined kind.

If you're using jaggery as your "healthy" sweetener in chai, cooking, or sweets, switch to a monk fruit or stevia sweetener blend (GI 0, GL 0) and you eliminate the glucose spike entirely. For snacking, choose guava (GL 1), strawberries (GL 4.5), paneer cubes, nuts, or a cheese cube with cucumber — real protein, real fat, real satiety. Not sugar dressed up in an earthen wrapper.

Three Practical Rules for Using GI and GL Together

Where Sugar-Free Sweeteners Fit In

This is where the GI/GL framework becomes powerfully relevant for anyone managing diabetes or simply trying to reduce sugar. The sweeteners we use at Artinci — stevia, monk fruit, erythritol — all have a GI of zero. That means their glycemic load is also zero, no matter how much you use. No spike. No insulin surge. No crash.

Now compare that to the sugar in your chai. Two teaspoons of sugar in one cup: GI of 65, about 10 grams of carbs. That's a GL of 6.5 per cup. Four cups a day — the Indian average — and your chai habit alone carries a cumulative GL of 26. Replace that with a monk fruit blend, and the GL drops to zero. Same warmth, same ritual, completely different metabolic impact.

But here's a critical warning: not all "sugar-free" products deliver on this promise. Many use maltodextrin as a filler — a processed starch with a GI of 85 to 105, which is higher than table sugar itself. A product can technically be labelled "sugar-free" while containing an ingredient that spikes your glucose faster than the sugar it replaced. Always flip the pack and check the ingredient list. If maltodextrin is in the first three ingredients, that product is not your friend.

Try this: for one day, look up the GL of everything you eat. Just one day. You might discover that the foods you feared (watermelon, carrots) are harmless — and the foods you trusted (jaggery in your chai, large portions of rice) are doing more damage than you thought.
