The answer lies in portion size cwk. For example, 1 cup of cooked spinach contains much more spinach than 1 cup of spinach raw. This is due to water loss from cooking.
When you measure out raw veggies, the FP will either be the same or slightly lower when you cook it. It will never be higher.
But when you measure a veggie that has been cooked recognize that you often will be getting more veggies and less water and air – its more concentrated.
That is why I included some examples of cooked veggies. When in doubt, measure the veggies out raw and use the corresponding FP whether or not you cook them.
