Snacks with 5g of sugar or less per 100g — ranked for blood sugar stability, keto compatibility and real satiety.
Sugar in a snack does two things worth caring about: it spikes blood glucose faster than any other macronutrient, and the crash that follows is what usually drives the next craving within an hour or two. A snack under 5g of sugar per 100g avoids most of that spike-and-crash cycle outright, which matters most for keto and low-carb eating but is worth checking even if you're not following either.

Which of these should you actually pick?
The "best" entry depends on your goal — here's how to read this list against three common ones.
Keto / low-carb: Pork chicharrónes, biltong and mini cheese rounds combine near-zero sugar with near-zero carbs generally — check these first if you're tracking net carbs, not just sugar.
Blood sugar stability: Roasted seaweed thins pair 2g sugar with 30g of fibre and 30g of protein, which is the combination that actually flattens a glucose response rather than just avoiding sugar in isolation.
Just cutting back on sugar: Olives and salted popcorn are both under 1g sugar per 100g and don't taste like a compromise the way some "low sugar" snack-aisle products do.
Where to buy
Most of these snack types are stocked in UK supermarkets (meat snacks and nuts in the food-to-go or world-food aisles, seaweed thins increasingly in the snack aisle) or available from the retailer links on each snack's own page above.
How we chose
Ranked by sugar per 100g first, then by protein and fibre — because a truly low-sugar snack should also keep you full. All figures are per 100g of the snack type.
