You'd need to check the sugar and total carbohydrate level I'm imagining each brand will vary.
Try looking at the detailed label on the back and avoid anything with more than 5g of carb per 100g.
You'll be amazed at how many things that knocks out of the trolley.
Most thai curry pastes have suger in them and come out about 15g carbs per 100g paste
The only way to know for sure if that level of carbs is ok for you or not is to test how your blood sugars respond
There are lots of recipes online for Thai green and red curry pastes which you can tweak to reduce the carb count, there are also many on low carb & keto sites that have already been tweaked
