How Many Syns in Sultanas?

By Jenny Updated

Sultanas are dried seedless white grapes, prized for their golden colour, plump texture and honeyed sweetness. On Slimming World they sit firmly in the Healthy Extra B family rather than the Free fruit list — and that is the single most important thing to grasp before you reach for the bag. Although fresh grapes are Free, the drying process concentrates the natural sugars dramatically, pushing sultanas to roughly 4.5 syns per 30g and 7.5 syns per 50g. That is similar to raisins, though sultanas carry a slightly lower calorie count per gram thanks to their grape variety and moisture profile.

The practical takeaway is that weighing matters enormously. A casual handful tipped onto your morning porridge can easily reach 40g, which is 6 syns before your day has properly begun. Far better to measure a level tablespoon (around 15g, roughly 2.5 syns) and stir it through hot oats, natural yoghurt or a bowl of overnight bircher where the sweetness has time to bloom and feel generous. Soaking sultanas in a splash of hot tea or orange juice for ten minutes plumps them beautifully, making a smaller portion feel far more indulgent.

Sultanas earn their syns when you use them strategically: scattered through a curry to balance chilli heat, simmered into a Moroccan tagine, baked into a fruity scone alongside your Healthy Extra B allowance, or chopped finely through a Speed-heavy carrot and apple slaw. They also work brilliantly in homemade granola bars where a little sweetness goes a long way. Avoid grazing them straight from the packet — the syns mount silently. Treat sultanas as a flavour-builder rather than a snack, weigh every portion, and they remain a useful, naturally sweet store-cupboard staple within a Food Optimising plan.
