Weighing pasta?

[poppym12]

Could someone explain it to me please?
I'm thinking of having maceroni later but the nutritional info on the box relates to dry pasta.
Does it suddenly increase in calories and carbs because its soaked up water and is therefore heavier?

No I don't think so? I just go off what's on the box. So I weigh e.g. 75g of dry pasta before cooking and then whatever the cals/carbs says on the box, that's how much I've had. If you are adding anything to the pasta itself like oil you could account for that I suppose but if you are literally just boiling it there's nothing to add, water has no calories so even if it's heavier once cooked it's the same cals?

that's what I thought but I'm confused about the information on a different packet I have which gives 100g and 200g serving info (cooked as per instructions without salt) and stating that 90g of pasta weighs approx 200g when cooked.
If I weigh 100g dry pasta the calories would only be 154g. Cooking it doubles the weight and becomes a 200g serving, the calories would be 309 .

You would weigh the portion of dry pasta (usually approx 75g) it would increase in weight as you cook it (due to absorbing water) but the calorie count remains the same.

thanks. I've avoided pasta so far thinking that it would be way too carbohydrate heavy. pleasantly surprised that it fits easily into my MFP tracking.

On that packet the 200g is just double the 100g info. I don't think it's anything to do with cooking and changing weight.

I've only ever used the dry weight to measure pasta.

I think that nutrition info is food cooked weight though... Pasta is usually around 350 calories for 100g dry weight not 154 it’s a little misleading
