How
to Read the
Nutrition Label for Fat Information
by
Mary Choate, M.S., R.D.
Fats
in our diet supply essential fatty acids, important in cell membrane
structure and in the regulation of blood pressure, blood clotting,
and immune response. Fats are needed for the absorption of fat-soluble
vitamins and carotenoids that protect body cells from damage. As
we learn more and more about the role of fat in good health it is
clear that the kind of fat we eat is as important as the amount.
The
following information will guide you through the Nutrition Facts
label information so you will be able to make the best choices for
your diet.
Total
Fat
The Daily Value for Total Fat is 65 grams (based on 30% of a
2000-calorie reference diet, rounded). This is an upper limit. Your
personal limit may be higher or lower, based on your calorie needs
and health goals.
Saturated
Fat
The Daily Value for Saturated Fat is 20 grams (based on 10% of a
2000-calorie reference diet, rounded). This is an upper limit; less
is even more healthful.
Saturated
fat is related to increased levels of low density lipoprotein (LDL)-cholesterol,
the kind that clogs blood vessels with cholesterol deposits, leading
to heart disease.
Animal
fat, whole milk dairy products, and tropical oils like coconut,
palm kernel, and palm are rich in this kind of fat and should be
avoided.
Select
a liquid or tub margarine that has water or liquid vegetable oil
as the first ingredient, and that has no more than 2 grams of saturated
fat per tablespoon.
Polyunsaturated
Fat
There is no Daily Value for polyunsaturated fats, but the American
Heart Association recommends that up to 10% of calories come from
polyunsaturated fats. That would be a maximum of 20 grams (based
on 10% of a 2000-calorie reference diet, rounded). The average American
diet contains too much of this kind of fat.
Some
polyunsaturated fat is necessary in our diet to supply essential
fatty acids that our body requires. In excess, this kind of fat
tends to lower levels of both LDL-cholesterol and high-density lipoprotein
(HDL)-cholesterol. HDL-cholesterol is the kind that removes artery-clogging
cholesterol from your body.
To
keep your intake in the proper balance, consume polyunsaturated
fats from small servings (1/4 cup) of nuts and seeds as snacks several
times per week, and select fatty fish, rich in heart-protective
Omega-3 polyunsaturated fats, one to several times per week. Try
switching to monounsaturated oils like canola, peanut, and olive
instead of polyunsaturated vegetableoils for cooking. Choose products
made with monounsaturated oils instead of polyunsaturated ones.
Monounsaturated
Fat
There is no Daily Value for monounsaturated fat, but the American
Heart Association recommends that up to 15 percent of total calories
should come from monounsaturated fat. This would be roughly 30 grams
(based on 15% of a 2000-calorie reference diet, rounded).
Monounsaturated
fat lowers damaging LDL-cholesterol levels, without affecting the
levels of good HDL-cholesterol.
Olive,
canola, and peanut oils, olives, peanuts, and avocadoes are rich
in this kind of fat.
Trans
Fat
Trans fat raises undesirable LDL-cholesterol levels. It is formed
when hydrogen atoms are added to vegetable oils, making them into
partially hydrogenated oils which are stable and solid at room temperature.
It also occurs naturally; small amounts are found in meats and in
milk.
Trans
fat is not listed on the Nutrition Facts label, but may be roughly
estimated on labels that include the amounts of saturated, polyunsaturated,
and monounsaturated fats by adding the amounts of these together
and subtracting from the total fat amount. Unfortunately, each of
the values may be rounded, so you will get a "guesstimate," at best.
You
will find trans fat hidden in most margarine, baked goods, and deep-fried
foods prepared with hydrogenated vegetable oils.
Liquid
oils such as olive, canola, soybean, and corn oils are free of trans
fat; and liquid or tub margarines are lower in trans fat than stick
margarines. To avoid the trans fats in your spread, look for a trans
fat-free margarine. This means it contains less than one-half gram
of trans fat per tablespoon. (One- half gram is a negligible amount,
about the size of half a raisin.) Be aware that trans fat-free does
not mean free of all fat or free of saturated fat. Read labels carefully
to get the whole picture.
How
Do You Put It All Together?
Read labels to find products with the least amount of saturated
fat, and look at ingredient lists to spot partially hydrogenated
oils, which indicate the presence of trans fats.
Cook
with monounsaturated fats and choose products made with them more
often.
Use
the Nutrition Facts label to keep your total fat intake below 65
grams and your saturated fat intake below 20 grams per day.
