NESTLE: That's just nutritionists' jargon
for a food that's rich in nutrients and low in calories.
Junk foods, of course, are just the reverse.
FERGUSON: You mentioned to me once that
you require your medical students to record a 24-hour diet
inventory. How useful is such a practice . . . and what's
involved?
NESTLE: Well, the process is a bit
tedious, but it teaches a great deal about the importance
of watching what you ingest. You simply list everything you
eat and drink in one day, and afterwards look up the
nutrients present in each edible in standard food
composition tables. Then add up the daily totals, and
compare those figures with nutritional guidelines such as
the U.S. Recommended Daily Allowances. It's fascinating to
find out which nutrients are present in common foods. Many
people, for example, are surprised to find how much protein
is in vegetables.
FERGUSON: What books would you rec ommend
for those who want to do a one-day, diet inventory?
NESTLE: Composition of Foods, and Laurel's
Kitchen. Composition is the standard source for nutritional
information. Laurel', Kitchen is a vegetarian cookbook with
a long and truly excellent section on the principle, of
nutrition . . . and the text is accompanied by very handy
food-composition tables. I just wish that the book included
more information for people who eat meat!
FERGUSON: Do you have any advice on how to
shop for groceries . . . and how to determine which foods
are nourishing and which are not?
NESTLE: Yes. If you buy food in a
supermarket try to avoid the center aisles. All of the
real, unprocessed foods—the vegetables, fruits,
meats, and dairy products—are generally located
around the periphery of the store. But the low-nutrient
junk foods are usually kept in the center aisles, so stagy
away from those areas. And by all means, read the products'
labels. The information on such wrappers isn't always
complete, but at least it will tell you which products do
and do not contain undesirable ingredients such as sugar,
salt, fats, and additives.
