An estimate of the quantity or bulk of food may be of assistance or interest. There is so much variation in the size of tablespoons or what may be termed either rounding or heaping tablespoons that it must be remembered that we can only estimate. Patients who are instructed how to feed themselves on leaving the hospital are cautioned carefully to take about the quantity of an article of food they have been served while in the hospital when the diet is weighed. Any written advice is always given in quantities known to be _under_ the carbohydrate or protein tolerance of the patient. However, if they will boil the vegetables and change the water at least twice, so much carbohydrate is removed that it is quite possible for them to obtain a comfortable bulk and still take in very small quantities of carbohydrate. 100-Gram Portions.
