How much sauce are you putting on your food though? 17% sugar is bad in a drink where it adds up fast, but for a hot sauce where you're using maybe 2 teaspoons max (likely less), that's like 1-2 grams of sugar. Essentially a rounding error in your daily intake.

Sure, you can skip sugar entirely if you want to. But then you're getting a different flavor entirely. Southeast Asian stuff is often sweet and spicy and gets that flavor through sugar. No way around it, unless you're using artificial sweeteners.
