Deliver the good news that eating for heart health
can mean variety, taste, and satisfaction.
For someone hearing the words “heart-healthy
diet” for the first time, an initial thought may be, “Bye-bye
favorite foods, hello tasteless diet.” Associating certain
words with foods is a natural tendency. The word birthday evokes
thoughts of cake and ice cream, Halloween implies pumpkin picking
and candy from trick-or-treating, and Thanksgiving brings thoughts
of turkey and all the trimmings.
As dietitians, we must focus on helping clients
clarify, and in some cases change, certain word associations, especially
implicit messages involving food. It is the dietitian’s job
to make nutritional messages explicit. We must teach ways to bake
the cake using low-fat ingredients, toast the pumpkin seeds in a
light coat of olive oil for a healthy dose of monounsaturated fat,
downsize the amount of candy eaten, and prepare Thanksgiving turkey
lean, skinless, and with whole wheat stuffing. Cardiac patients
attempting to battle the dietary villains of sodium, saturated fat,
and cholesterol may be missing the most important point of all:
learning what foods they can (and should) eat more of.
From apples to zucchini, nutritious food choices
span the alphabet. To help clients eat heart-healthy, we need to
teach specific topics, provide learning tools, and help the client
translate nutrition principles into practice.
Fats: The Good, the Bad…
People don’t walk around boasting about how they limited today’s
saturated fat intake to less than 10% of total calories. They think
in terms of food choices. We need to provide concrete nutrition
tips that support a heart-healthy intake of fats. Fat is a macronutrient
that supplies energy to the body (9 calories per gram). It is needed
to keep cells healthy (eg, skin, hair, nails), regulate metabolic
processes, and transport certain vitamins and minerals throughout
the body.
To help clients understand the role of dietary fat
in promoting heart health, clarify distinctions among types of dietary
fat. Saturated fat is solid at room temperature. It is found in
greatest amounts in foods from animals, such as fatty cuts of meat,
poultry with the skin, whole-milk dairy products, and lard. Some
vegetable oils, including coconut and palm oils, also contain saturated
fat. Make sure patients understand that saturated fat is the main
dietary source of high low-density lipoprotein (LDL) cholesterol.
The egg has long been labeled as a bad food because of its high
cholesterol content. But eating a meal high in saturated fat such
as grilled cheese (prepared in butter) with 1 cup of whole milk
will raise blood cholesterol more than eating scrambled eggs on
whole wheat toast.
Remind patients that they don’t have to cross
out red meat from their grocery list as long as they select healthier
cuts. For instance, 3 ounces of lean sirloin steak has less saturated
fat than 3 ounces of chicken with the skin. Advise your clients
to select extra-lean ground beef that appears cherry red in color;
avoid pink-colored beef, since pink is formed from a mixture of
white (saturated fat) and red. More importantly, encourage clients
to maintain dietary variety by incorporating vegetarian sources
of protein such as beans and tofu that are naturally low in saturated
fat.
As fats become more solid, they become more saturated,
which increases their artery-clogging potential. An easy recommendation
is to tell clients to use soft and liquid fats over solid fats.
They may also be interested in specialty spreads and sprays. I Can’t
Believe It’s Not Butter! spray is calorie-, cholesterol-,
fat-, and sodium-free. Once clients set aside their reservations
about spraying their food, it serves as a great way to save on extra
calorie consumption and can be used on bread or popcorn for extra
flavor. Some soft spreads such as Benecol contain plant sterol esters,
which may also help lower blood cholesterol. If clients insist on
using butter, encourage portion control through the use of teaspoons
over tablespoons.
Foods from plants, including olive, canola, and
peanut oils, along with many nuts (walnuts, almonds, pecans), contain
significant amounts of monounsaturated fat. This type of fat should
comprise the bulk of a client’s fat intake because it has
been shown to help lower blood cholesterol without lowering high-density
lipoprotein (HDL) cholesterol levels.
Polyunsaturated fats are usually liquid at room
temperature. Omega-6 is one type of polyunsaturated fat and most
prevalent in plant-based foods, including safflower, sunflower,
corn, soybean, and cottonseed oils. Omega-6 fatty acids may help
lower total blood cholesterol when substituted for saturated fat.
Omega-3 fatty acids are polyunsaturated fats found in many oily
fish. The highest ranked species of fish are Pacific herring, Atlantic
herring, Pacific mackerel, Atlantic salmon, and sablefish (contain
2 or more grams of omega-3 fats for a 4-ounce serving, cooked).
Other good sources of omega-3s include canned pink
salmon, trout, oysters, whitefish, and sardines. Fish is an excellent
source of lean, high-quality protein, assuming one does not fry
it in saturated fats such as butter. Grilling, baking, poaching,
or lightly sauteing in olive oil are heart-healthy ways to prepare
fish. In addition, eating protein with meals promotes satiety, making
one less likely to overeat.
If your client does not like fish, ground flaxseed
and soybeans are potent plant sources of protein and omega-3s. Flaxseed
and flaxseed oil are available at health food stores and supermarkets.
Flax also contains dietary fiber and lignans. Fiber adds bulk to
meals, maintains bowel regularity, and may help lower blood cholesterol.
Lignans are plant compounds that can have favorable hormonelike
effects in the body. Flax has a light nutty flavor, making it a
tasty addition to cereals, salads, casseroles, soups, smoothies,
pasta, and baked goods.
Omega-3 fatty acids have been promoted for their
amazing health properties. Omega-3 oils alter the production of
a group of biological compounds called eicosanoids, which may decrease
the risk of heart disease, inflammatory processes, and certain cancers.
They have been shown to exert cardio-protective effects by decreasing
blood lipids (LDL cholesterol and triglycerides), decreasing blood
clotting factors and inflammatory processes in the vascular system,
and increasing relaxation in larger arteries and blood vessels.
…and the Trans
What makes up the creamy filling of an Oreo cookie? Trans fatty
acids have been identified as a new dietary promoter of heart disease,
specifically for its artery-clogging properties. Trans fat refers
to a fatty acid that has been chemically altered by a process called
hydrogenation. Hydrogenation changes liquid vegetable oil into a
more solid saturated fat. These fats are often used to maintain
the stability of food products, thus prolonging their shelf life.
Trans fats are primarily found in processed foods
under the code ingredient “partially hydrogenated” and
are frequently used in low-fat items such as cookies, crackers,
granola bars, popcorn, and peanut butter to enhance flavor. They
are also found in a variety of baked and fried goods, along with
some margarines. In fast foods, these artificial fats occur in salad
dressings, buns, chicken items (chicken breasts, patties, nuggets,
or tenders), french fries, milk shakes, seasonings, and croutons.
In response to health concerns related to trans
fats, brand-name products have already produced new lines of trans-free
foods. Smart Beat Super Light, Fleischman’s Lower Fat, and
Promise Ultra 70% Less Fat have 2 to 5 grams of fat per tablespoon,
with no more than 1 gram of trans fat—but keep in mind that
they still have many calories. Your clients are still probably better
off eating moderate portions of foods containing unsaturated fats.
By January 2006, the FDA requires all manufacturers
to list the trans fat content on the food label. The new label lingo
allows a product to be called “trans-fat free” if it
contains less than 0.5 grams trans fat per serving. For this reason,
it is still wise for clients to read the ingredients on the food
label and trace for key words such as “hydrogenated vegetable
shortening” or “partially hydrogenated oil.”
The easiest way to avoid excessive intake of foods
containing trans fats is by encouraging them to choose whole foods
over processed foods. One is better off eating the apple over the
apple pie. A serving size of nuts and dried fruit serves as a healthier
snack than reduced-fat peanut butter on low-fat crackers. The bottom
line is that dietary sources of saturated fat and trans fat should
both be minimized.
Food Label Savvy
On September 8, 2004, the FDA announced that food companies could
make qualified health claims on food labels concerning the heart-healthy
benefits of omega-3 fatty acids. Qualified health claims are intended
to keep consumers well-informed of the health benefits of certain
nutrients in foods. It is important to note, however, that such
statements are based on limited scientific research.
The FDA limited the claims to two omega-3 acids
known as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA),
which may help reduce blood triglycerides, increase HDL cholesterol,
and reduce blood pressure—all actions that help lower coronary
heart disease risk. Manufacturers are required to list the content
of EPA and DHA in a food. Foods that exceed 13 grams of total fat
or 60 milligrams of cholesterol per serving cannot carry the claim.
The American Heart Association recommends that people
with heart disease consume 1 gram of omega-3 fatty acids per day.
It is also advised to consume at least two servings per week of
fatty fish, which contains both EPA and DHA. In light of warnings
concerning mercury and other chemicals found in fish, the FDA announced
that eating up to 12 ounces of fish is safe for everyone. Since
a serving size of fish is 3 to 4 ounces, eating two servings per
week is well below the FDA’s safe limit.
While soy, flaxseed, flax oil, and flax-based omega-3–enriched
eggs contain no EPA and DHA, they’re a rich source of another
omega-3 known as alpha-linolenic acid (ALA). The body can use ALA
to manufacture EPA and DHA. A weekly intake of 6 to 8 grams of omega-3s
will help your clients reap the protective benefits of these oils
against coronary heart disease. Finally, the FDA advises that consumers
not exceed more than 2 grams per day of omega-3 fatty acids from
dietary supplements. It is still preferable to encourage consumption
of whole foods, which contain omega-3s in addition to other nutritional
components.
Qualified Health Claims
Whereas traditional health claims for food (such as the role of
whole grains in reducing blood cholesterol) required years of scientific
research and regulatory approval, qualified health claims shorten
the process. Olive oil and walnuts have also been approved for qualified
health claims.
On March 31, 2004, the FDA said “supportive
but not conclusive research” shows that eating 1.5 ounces
of walnuts per day may reduce coronary heart disease risk. On November
1, 2004, the agency announced that there is limited but not conclusive
evidence that consumers may reduce their risk of heart disease by
substituting monounsaturated fat from olive oil (approximately 2
tablespoons) in place of foods high in saturated fat. Research recently
published in The Journal of the American Medical Association supports
decreased mortality rates among older Europeans following a Mediterranean
diet rich in unsaturated fats, fruits, vegetables, beans, nuts,
and fish.
Still, it is important to consider this: Is it really
necessary to send consumers more information if it is only semireliable?
Just as there is no magic pill for weight loss, there is no magic
food for disease treatment and prevention. After all, one can gain
a lot of weight simply by eating walnuts, cooking with olive oil,
and eating omega-3 fortified eggs. The FDA specifically states that
these foods should be consumed as part of a low-calorie diet, but
consumers may skip the fine print and favor a “more is better”
philosophy. These foods offer health benefits only if they are incorporated
into a well-balanced diet. Although using qualified health claims
to help consumers make informed food choices seems like a benign
purpose, there is more to the story.
The incentive behind posting health claims on food
packages also involves the manufacturer’s interest in selling
the product and gaining a competitive advantage. Nonetheless, this
incentive may start to fizzle with the new relaxed policy regarding
the use of qualified health claims. At the July 2004 Institute of
Food Technologists Annual Meeting and Food Expo, food industry leaders
addressed the significance of the FDA’s proposed “qualified
health claims” and the challenge it poses for food marketers.
Qualified claims aren’t ownable messages if all manufacturers
can apply and find some sort of claim to place on their products.
Different varieties of claims will weaken the impact of the messages,
and ultimately detract from a unique marketing position.
As dietitians, we have two choices: We can either
continue debating that these claims are too vague and confuse consumers,
or we can team up with the FDA initiative to help Americans make
healthier dietary choices. The latter choice will exemplify the
role and enhance the credibility of RDs in the 21st century. The
FDA laid out the facts. For instance, it is true that eating 1.5
ounces of walnuts per day, as part of a low-saturated fat and low-cholesterol
diet, and not increasing caloric intake may reduce the risk of heart
disease.
We are the ones who must deliver the message and
show clients the “how-to” part. Helping clients personalize
their calorie needs and identify dietary sources of fat will help
them keep within their limits of unhealthy saturated and trans fats.
By tracking their food diaries, we must ensure that the walnuts,
olive oil, and omega-3 fats in their diet are eaten in moderation
with high-fiber starches, low-fat dairy, fruits, and vegetables.
For clients interested in eating healthy fats but also trying to
lose weight, recommend ways of adding small quantities of omega-3s
to recipes, such as sprinkling walnuts on salads, using olive oil
for stir-fry dishes, or preparing canned salmon with fat-free mayonnaise.
Dietitian’s Dilemma
In an ideal world, dietitians would be the only voices giving dietary
advice on heart-healthy eating. In reality, I know this is not true
since I spend a good portion of my day reading information related
to the latest fad diets and food products. Once, I even started
a counseling session with a copy of a grapefruit diet my client
brought in. She was taking Lipitor, a statin drug, and should have
been avoiding grapefruit due to potential drug-nutrient interactions.
There is an abundance of dietary information communicated through
the Internet, magazines, television, and friendly conversations;
some is reliable, some is nutrition quackery, and some is unsafe
for clients at risk for heart disease.
We must be fully prepared to address this trend
and provide clients with credible information. For clients trying
to reduce their risk of coronary artery disease, why shouldn’t
they believe that a Nature Valley granola bar is more nutritious
than a Snickers bar? In reality, a Snickers bar has more fiber.
For this reason, it is helpful to provide clients with specific
criteria for choosing heart-healthy foods. Nutritional information
on food packages can be used as a teaching tool in helping clients
become food-label savvy.
Successful Strategies
Keep sample food packages in your work environment. You can arrange
a “food lineup” using five different food labels. Ask
the client to choose one snack he or she would eat based on nutritional
content and personal preference. Guide the client in analyzing the
food label. The snack that meets the most criteria is the “heart-healthy”
choice. Use trick foods such as fruit snacks labeled “excellent
source of vitamin C.” Clients may be surprised to learn the
sugar and calorie content exceeds levels considered heart-healthy.
This will help clients think of alternative food sources of vitamin
C such as fresh fruit.
Dietary intake, both the quantity and quality of
foods consumed, greatly affects heart health. Use the client’s
existing dietary intake as a base for healthy modification to illustrate
this point. For instance, a client may tell you that a typical Chinese
dinner is chicken with vegetables over rice. You are probably asking,
“Is the chicken steamed? Is the rice brown or white? And did
the client eat from the container or plate the food?” Although
these questions come automatically to the trained professional,
the challenge is to help clients acquire these skills. If the client
ate one-half of the portion served but the meal was fried, then
the focus of the session should be on choosing healthier options.
If the client ate an entire order of steamed chicken with vegetables
over a pint of brown rice, later followed by 11/2 cups of low-fat
frozen yogurt, portion control is the apparent learning need.
Clients can learn to plan nutritionally balanced
meals by looking at their diets as a whole, not as good foods vs.
bad foods. Advise clients to pay close attention to how much they
eat by plating their food. This is particularly important for clients
who eat take-out, prepare large bulk meals, or attend cocktail parties
where appetizer trays are floating around the room. The reason why
only 7% of the population in France is obese compared with 30% of
Americans has little to do with genetics or drinking red wine. Preventing
excess weight gain is associated with eating sensible portions from
each food group.
Making mealtime a designated activity is very important.
I often instruct clients to enter “breakfast,” “snack,”
“lunch,” etc. into their Palm Pilot as a reminder to
take time from work and concentrate on eating. It takes 20 minutes
for the brain to register fullness from a meal. It is easy for rapid
eaters occupied with other activities to exceed their calorie limit
in that time period. If possible, encourage your clients to eat
mini meals every three to five hours to avoid rebound hunger and
help increase the nutritional variety of their diet.
Meal Planning Tips
Although all meals are important, heart-healthy eating starts with
a balanced breakfast. Eating a nutritious breakfast energizes the
mind and body so one can perform daily activities at peak level.
Whether clients choose a blender shake or an egg omelet on whole
wheat toast, a hearty breakfast will prevent them from overindulging
at later meals. A 200- to 300-calorie breakfast can comprise anything
from one Kashi Go Lean waffle topped with strawberries to an Egg
Beater omelet with vegetables. Encourage clients to “mix it
up” by some days eating a protein-based breakfast and some
days eating a starch-based breakfast (high-fiber).
Provide clients with a skeleton model for meals.
For instance, lunch can be a soup, sandwich, or salad base. Clients
can fill in the blanks with foods they enjoy. Encourage vegetable-,
bean-, and lentil-based soups, whole grain breads for sandwiches,
and creative salad ideas. Recommend adding lean protein such as
tuna canned in water, legumes, tofu, or grilled chicken to salads
for a more satisfying meal.
Lastly, clients can fill in the nutritional gaps
of their day with healthy snacks and dinner. For example, if breakfast
and lunch lacked in fiber, clients can get their daily boost from
a stir-fry dish using frozen or fresh vegetables over whole wheat
couscous. Nutrient-dense snacks include nonfat yogurt topped with
fresh fruit and 100% whole wheat crackers (eg, Kavli, Ryvita, Wasa)
spread with 1 to 2 tablespoons of hummus. Easy heart-healthy recipes
can help your clients plan nutritious meals and are available at
the American Heart Association Web site (www.americanheart.org;
click on Healthy Lifestyle, Delicious Decision).
People are more likely to make dietary changes that
they perceive as important and achievable. We must be good listeners
and customize our dietary advice to fit the personalities and lifestyles
of our clients. For a client on the go, encourage “harm-reduction”
tips. For instance, a stop at Starbucks can be nutritious if one
chooses a cafe latte made with skim or soy milk. Portable snacks
such as instant oatmeal, precut vegetables, and heart-healthy trail
mixes (small baggies of dried fruit, nuts, seeds, and high-fiber
cereal) can prevent one from buying empty-calorie foods impulsively.
A client who just won’t give up on a jumbo
breakfast bagel does not want to hear the words, “Thou shall
forgo bagels forever.” Advise the client to scoop out the
bagel and put something nutritious inside, such as 2 teaspoons of
natural peanut butter with sliced bananas. Provide alternatives
such as eating half the bagel with a yogurt or choosing a mini whole
wheat bagel for breakfast, balanced with a vegetable and protein-based
lunch and dinner. Remind clients that combining a variety of food
groups at each meal will make it easier to meet heart-healthy guidelines.
By revising the bagel breakfast, the client learns how to turn a
500-calorie meal of refined carbohydrates into a 500-calorie nutrient-dense
package of unsaturated fats, antioxidants, and lean protein.
The credibility of RDs goes beyond simply preaching
good nutrition. We must practice it. We don’t have control
over certain cardiac risk factors such as age, gender, and family
health history, but we can modify our dietary intake. By establishing
personal levels of fitness and nutrition, we are living proof that
a physically active lifestyle balanced with heart-healthy eating
habits serve for both the prevention and treatment of cardiac disease.

Omega-3 Fats Sources
Alpha-linolenic acid sources:
1 tablespoon of ground flax = 1.8 grams omega-3 fats. Ground flax
is recommended over eating whole seeds because it is easier to digest.
1 tablespoon of flax oil = 8 grams of omega-3 fats.
One teaspoon of flax oil will meet your daily needs.
Eicosapentaenoic acid and docosahexaenoic acid sources:
1.5 ounces of fatty fish = approximately 1.5 grams of omega-3 fat
(salmon, tuna, mackerel).
