How many teaspoons of sugar in mango juice?

Mango juice is the last row of Dr Unwin’s South Asian foods chart, at a 200ml glass, and the only drink on that chart. It is given a glycaemic index of 55, at the top of the band conventionally called low.

The chart does not describe the juice further, and mango juice is sold in very different forms. There is pure pressed or puréed mango; mango nectar, diluted with water and usually sweetened; and mango drinks that contain a small share of fruit with added sugar. Tinned mango pulp, sold across South Asia and in South Asian shops elsewhere, is often sweetened too. These products differ in both the amount and the kind of sugar they contain, and the chart’s figure describes one of them without saying which.

The chart prints the GI and the teaspoon figure but no glycaemic load, so the load on this page was back-calculated.

Mango lassi, made with yogurt, and aam panna, made from green mango, are different drinks again.

Mangoes come in many varieties across South Asia, such as Alphonso and Kesar in India and Chaunsa and Sindhri in Pakistan. Whole mango is not on any of the charts used here, so this site has no figure for it. The 2016 paper mentions mangoes among the tropical fruits discussed in Dr Unwin’s practice leaflet, without a figure.

The other juice in the dataset, apple juice, comes from a different chart.
