How Many Syns in Doritos Cool Original?

By Jenny Updated

Doritos Cool Original are one of those crisps that have a knack for disappearing from the bowl far quicker than you intended, and on Slimming World they sit firmly in the 'plan it in carefully' category. A standard 30g bag weighs in at around 7.5 syns, which is slightly higher than a comparable bag of plain salted tortilla chips. The extra syns come from the seasoning blend: buttermilk powder, whey, dairy solids and a touch of sugar all add fat and carbohydrate that nudge the calorie count up to roughly 152 per bag. They are triangular, crunchy and engineered to keep you reaching back in, which is precisely why I prefer the single-serve bag rather than the sharing pouch.

On a Food Optimising day, Doritos Cool Original work best as a planned treat rather than a default crisp. If you fancy something cheesy and tangy with a film, build the syns in around a Speed Free meal so the rest of your plate is doing the heavy lifting. A jacket potato loaded with baked beans, salad and fat-free yoghurt-and-chive dip leaves room for a 30g bag on the side without the day spiraling.

Because the seasoning is what drives the syn value, decanting the bag into a small bowl is a small but useful trick. Spreading the crisps out makes them feel like more, and pairing them with crunchy Speed Foods like cucumber batons, cherry tomatoes and pickled jalapeños turns a quick handful into something that looks and eats like a proper snack plate. Avoid the multipack 'grab bags' (typically 40g and around 10 syns) unless you weigh out a portion first, and steer clear of the dips entirely unless you have synned them in.
