Navigating Food Labels
by: Dianne Villano, CPFI
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? Try to get an accurate measurement once
in a while. I generally recommend breaking out the measuring utensils
for a month until you get proficient at eyeballing.
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 1500 - 1,800 calories or fewer per day, while males
need about 2,200. click here to get a rough estimate of your caloric
needs
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.
Figuring Out fats
We've come a long way since the days of "cutting the fat"
We need fat in our diets -- The AHA and ADA recommend 20 to 30
percent of our daily food intake should come from fat, with no
more than 10% of your daily calories coming from saturated (bad)
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 and contribute
to arteriosclosis
Transfats : 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!
CARBOHYDRATES ARE NOT ALL BAD
Carbs are taking a bit of a bashing 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.
Clearly, there are different types of carbs and they are not
all created equal. 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). Be Aware that most women on
a fat reduction food plan will take in closer to 1500 calories
a day, so adjust accordingly
