A reader recently wrote in asking for help deciphering a food label --
I don't think she had any idea what a complicated question that really
was! Believe it or not, the Nutrition Facts panel on the food label is
designed to be straightforward.
I don't know about you, but I don't find it simple. You're supposed
to start by looking at the top of the panel -- right where the
confusion begins. The serving size issue alone can become a 30-minute
discussion.
Here are a few tips to help you dissect the food label before your next visit to the supermarket:
SERVING SIZE MATTERS
Just
because the food label lists a certain number of calories per serving
does NOT mean that's how much YOU eat. In fact, almost everyone I know
consumes much more than the serving size listed on the Nutrition Facts
panel. Many times the amounts are just not realistic, and most people
-- rather than counting out 15 chips or measuring a three-ounce serving
-- either fool themselves into thinking they're eating the "right
amount" or ignore it altogether. And because the ENTIRE Nutrition Facts
panel is based on the "serving size," it's very important to get it
right or all the information will be inaccurate.
So,
what should you do? I'm not suggesting you sit there with a measuring
cup or a scale every single time you eat, but try to get an accurate
measurement once in a while. At the very least, measure how much food
your bowls, glassware, and plates can hold. Learn a few quick "eyeball"
estimators -- for instance, you can use the size of your fist as a
guideline for measuring a half cup of cooked pasta.
Comparing
calories from food to food is also confusing because food densities
differ, so a volume-to-volume approach doesn't always work. It would be
simpler to comparison-shop if there was a "calories per gram" standard
on the panel -- similar to the way supermarkets have "unit"
pricing.
CALORIES ARE KEY
The
reality is that calories are a good thing -- they're a source of
energy. The problem arises when we eat too many of them. Females
typically need 1,800 calories or fewer per day, while males need about
2,200. A quick rule of thumb to calculate your calorie needs is 10
calories per pound of your current weight for weight loss or 14
calories per pound for weight maintenance.
If you still have
trouble understanding the value of a calorie, keep this in mind: for
every extra 100 calories you eat each day, you would have to walk for
an additional 25 minutes to burn it off. At least you'll have something
to relate to the next time you reach for that second bite of cake.
Oh,
and about those "Calories from Fat" on the Nutrition Facts panel -- as
a general rule, a low-fat food should have no more than 20 percent of
the total calories from fat. So if you have a food with 200 calories,
and 100 calories are from fat, do the math -- fifty percent of its
calories from fat, far from 20 percent, so it's not a low-fat food.
DEMYSTIFYING FATS
We've come a long way since the days when all
fats were taboo. We need fat in our diets -- it's recommended that
about 25 to 30 percent of our daily food intake should come from fat,
with limited "bad" fats and an emphasis on "good" fats.
The Bad Fats
Saturated:
These fats, which are listed on the label, are found primarily in
animal products like meat, whole-milk dairy products, poultry skin, and
egg yolks. Consuming too many of these fats can raise your "bad"
cholesterol levels; therefore, less than 10 percent of your total
calories should be from saturated fat.
Trans: This fat was
created to increase food shelf life. Manufacturers take healthy
polyunsaturated oils and blast them with hydrogen gas to solidify them,
and, in the process, make them incredibly unhealthy. The problem is
that trans fat won't be listed on the label until 2006, so you need to
look for trans fat clues. Know "suspect" foods, such as margarines
(unless they say "no trans fat" on the label), shortenings, deep-fried
foods, fast foods, and many commercial baked goods such as pies,
cookies, cakes, crackers, and doughnuts. Check the ingredients list,
and be on the lookout for partially hydrogenated oil -- if it's there,
you have trans fat. Also, many products now promote that they are
"trans fat free" -- look for this on the front of the packaging.
The Good Fats
Unsaturated
fats are found in products derived from plant sources, such as
vegetable oils, nuts, and seeds. There are two main categories:
Monounsaturated:
These fats are found in high concentrations in canola, peanut, and
olive oils, as well as olives, peanuts and peanut butter, and avocados.
Studies have found that monounsaturated fat helps lower LDL (the "bad")
cholesterol and raise HDL (the "good") cholesterol levels in your body.
Polyunsaturated:
These fats are prevalent in sunflower, corn, safflower, cottonseed, and
soybean oils, nuts, and fish (omega-3). They've been found to help
lower total cholesterol levels and prevent heart disease (particularly
the omega-3s).
Unfortunately, neither type of "good" fat is
required to be listed on the food label, but some companies do provide
this information. You can also subtract the saturated fat from the
total, and check the ingredient list for trans fat clues -- anything
left over is probably "good" fat. You'll only get a vague idea, but
hey, it's better than nothing!
LIGHT ON THE CHOLESTEROL AND SODIUM
The
idea is to keep cholesterol as low as possible. If the product has
cholesterol, check the Percent Daily Value, and make sure it isn't
high. For most healthy people, the recommendation is to keep
cholesterol intake at no more than 300 mg per day.
As for sodium
(or salt), your daily intake should be moderate -- the recommendation
is less than 1,500 mg, which is pretty tight if you eat a lot of frozen
meals, canned foods, broths and soup mixes, or condiments. Look for low
sodium or "no salt added" products to give you a little leeway.
CARBOHYDRATES ARE NOT ALL BAD
Carbs
are taking a big hit these days, even though they are an important
nutrient and necessary for survival. Foods that contain carbohydrates
include fruits, vegetables, starches, beans, nuts, milk, and yogurt.
Carbohydrates are also found in any food that contains sugar such as
cookies, cakes, soft drinks, syrups, and, of course, table sugar.
Are
there different types of carbohydrates? Absolutely. While most carbs --
sugar is the best example -- are digested and turned into blood sugar,
other carbs behave differently. In fact, if you are looking at the
Nutrition Facts panel, you will see carbohydrates broken down into two
categories: dietary fiber and sugar.
What exactly is dietary
fiber? Simply put, it's the indigestible parts of plant cells. Although
it is a carbohydrate, fiber does not convert to glucose and thus does
not raise your blood sugar the way other carbohydrates typically do,
and it makes you feel full longer -- a good thing.
The "sugars"
section includes those that are present naturally in the food (such as
lactose in milk and fructose in fruit), as well as sugars added to the
food during processing. In most cases, your body can't distinguish
between the two. If you're interested in finding out whether a
sweetener has been added, check the ingredients list for terms such as
"sugar (sucrose)," "fructose," "maltose," "lactose," "honey," "syrup,"
"corn syrup," "high-fructose corn syrup," "molasses," and "fruit juice
concentrate."
A FEW CLUES
A Percent Daily Value
(%DV) is listed for each nutrient. These percentages are helpful for
determining a food's nutritional value, or lack thereof. They tell you
whether one serving of food contributes a lot or a little to your total
nutrient intake for the day (based on an average 2000-calorie diet).
