Giada tapes sometimes three episodes in one day, and they do multiple takes on a close-up of her eating. She doesn’t always eat and swallow every time, since they can do sometimes six to 10 takes with three episodes a day, and that would be like eating six to eight meals a day … The bottom line is, she most certainly does eat the food she prepares on the show, but does not always consume the whole dish, as that would be too much for most people to eat in one day.
