Gram for gram, white sugar and jaggery contain similar calories. Both are sources of sucrose. The difference is in what the sucrose comes with. White sugar has undergone multi-step chemical refining that removes everything except the sucrose — including all minerals, phenolic compounds, and the molasses fraction that gives raw sugarcane its nutritional character. Jaggery retains all of this.
The mineral difference
White sugar contains approximately 0.1mg of iron per 100g. Jaggery contains 11mg per 100g — 110 times more. White sugar contains negligible potassium. Jaggery contains 1,050mg per 100g — more than a banana. This matters: many Indian households consume 10–15g of a sweetener per day, so switching from white sugar to jaggery adds approximately 1–1.5mg of iron daily from this source alone.
“Jaggery was not India's traditional sweetener because it was the only option. It was the tradition because it was the better option. The question is whether we remember that.”
The glycemic difference
Jaggery's GI (55–68) is marginally lower than white sugar (65–70). The difference is not large enough to make jaggery safe for diabetics — both should be consumed in moderation. But for non-diabetics, the molasses phenolics in jaggery slightly slow sucrose digestion, and the mineral content makes it a nutritionally superior choice in virtually every other respect. Palm jaggery (Karupatti) has an even lower GI of 40–55.
- Replace white sugar with jaggery in chai — the flavour deepens and gains mineral roundness.
- Use jaggery in tamarind-based dishes — the iron from jaggery + Vitamin C from tamarind is excellent for iron absorption.
- Palm jaggery (Karupatti) has lower GI than sugarcane jaggery and higher iron — worth seeking out.
- Store jaggery in an airtight container away from moisture — it becomes sticky and loses texture when exposed to air.
