No, just no.Quote
What I think is meant by this is they are JUST carbs and devoid of nutriton, which is in itself false.Quote
Rice is basically just starch, but has a high amount of grams of carbs per 100g, which is useful if you need to hit carb totals.
Pasta, unless you are buying wheat free/gluten free is not a great choice, but this depends on your tolerance for them.
Potatoes are a good choice, packed full of nutrition I would eat only potatoes if I could hit carb totals with them alone.
Oats are also another idea. Fruit could be used PWO.
