a lot of this shoiws the variation beween uk and american laws. food stated is how much calories an adult needs, so 2000 for women and 2500 for men. serving sizes are in grams so there is no way you can overfill the cup-it's recommended 75g of pasta per person. so with your strange ways of quantifying, i got 3 right, although i'd question how you can quantify things that don't fill a 'cup' like pasta quills to get the right amount

Without going through all nine pages of this article, I can still say a couple of things:

First, if you're into packaged, prepared foods, never believe the serving size listed on the package. A package is ALWAYS one serving, no matter what. Pizza, Doritos, ice cream, little chocolate donuts, Lean Cuisine. It doesn't matter. One package, one serving.

Second, if you don't know by now how much you can eat without gaining weight, an article is not going to change anything.

Third, eat your vegetables.

I have routinely noted that the FDA 'serving sizes' have absolutely no connection with real portion sizing when I eat; I tend to ignore the 'nutrition farts' labelling as irrelevant and maintain my fitness by balancing portion sizing and bicycle riding and walking exercises and do quite well for 56 years old. I'd be in favour of trimming back or abandoning the FDA and most other bureaucracy.

One thing that is really flawed on this last question is restaurant portion sizes. It depends on what restaurant you are patronizing and in what part of the country. Denny's and Mac Donalds is one long way from a really nice place and some of the pricier ones even have pretty small portions.

I based my answers on European (continental) habits so got a few wrong - like the size of a restaurant meal or the size of a portion of ice cream. A few others were much more than I thought (serving of tofu, for example).
Thanks for making us think about it.
