Eating for LIFE
Eat
for life? Eat to improve your chances for a long and healthy life?
Yes, you can.
At a time when we seem to be overwhelmed by
conflicting diet and health messages, the National Cancer Institute
(NCI) and the National Heart, Lung, and Blood Institute (NHLBI) have
some good news: by making the right food choices, you may reduce your
risk of developing cardiovascular disease and cancer.
These diseases take the lives of more Americans than all
other illnesses and causes of death combined. Each day, about three out
of every four deaths in the United States will occur as a result of
cardiovascular disease or heart disease (like heart attacks and strokes)
and cancer. This need not be. Although no diet can ensure you won't
get a heart attack, stroke or cancer, what you eat can affect your
health. This has been shown by research of the National Cancer Institute
and the National Heart, Lung, and Blood Institute (two of this country's
National Institutes of Health), along with the research of other
scientists.
How does a
person eat for life? It's easier and more enjoyable than you might
think. The practical ideas in this booklet show you how to make
healthful, tasty, and appetizing food choices at home and when you're
eating out. They are consistent with the Dietary Guidelines for
Americans, published by the U.S. Department of Agriculture and the U.S.
Department of Health and Human Services. These seven basic guidelines
are:
* Eat a variety of foods.
* Maintain desirable weight.
* Avoid too much fat, saturated fat, and cholesterol.
* Eat foods with adequate starch and fiber.
* Avoid too much sugar.
* Avoid too much sodium.
* If you drink alcoholic beverages, do so in moderation.
The first
two guidelines form the framework of a good diet: eat a variety of
foods so that you get enough of the essential nutrients you need,
and eat only enough calories to maintain desirable weight. The next
five guidelines describe special characteristics of a good
diet-getting adequate starch and fiber and avoiding too much fat,
sugar, sodium, and alcohol. Although the guidelines are designed
for healthy adult Americans, these suggestions are considered especially appropriate
for people who may already have some of the risk factors for chronic
diseases. These risk factors include a family history of obesity,
premature heart disease, diabetes, high blood pressure, or high
blood cholesterol levels.
This
pamphlet focuses on five guidelines that are particularly related
to the prevention of heart disease and/or cancer: eat a variety of
foods; maintain desirable weight; avoid too much fat, saturated
fat, and cholesterol; eat foods with adequate starch and fiber; and
avoid too much sodium.
Keep in
mind that staying healthy requires more than just good nutrition.
Regular exercise, getting enough rest, learning to cope with stress, and
having regular physical checkups are important ways to help ensure good
health. Checkups are especially important for early detection of cancer
and heart disease. Another important way to reduce your risks of heart
disease and cancer is not to smoke or use tobacco in any form.
Controlling high blood pressure (hypertension) can also greatly reduce
your risk of heart disease and stroke. Remember, three of the major risk
factors for heart disease are largely under your control. They are
smoking, high blood pressure, and high blood cholesterol.
How Do the Foods We Eat Affect Our
Chances of Getting Cancer and Heart Disease?
There is
much still to be learned about the relationship between the foods
we eat and our risk of getting cancer and heart disease. The NHLBI
and NCI are conducting a great deal of research to find out more about
this relationship. There is, however, a lot that we know now. The
relationship of diet to cancer and the relationship of diet to risk
factors for heart disease are summarized below:
Obesity
* We know that obesity
is associated with high blood pressure, high blood cholesterol,
diabetes, heart disease, and stroke, Extreme obesity has also been
linked to several cancers. This means that if you are obese,
losing weight may reduce your chances of developing these serious diseases
or conditions. If you already suffer from hypertension and are
overweight, weight loss alone can often lower your blood pressure
to normal levels. Because fat (both saturated and unsaturated fat)
provides more than twice the number of calories provided by equal weights
of carbohydrate or protein, decreasing the fat in your diet may
help you lose weight as well as help reduce your risk of cancer and
heart disease. Today, most Americans get about 37 percent of their
daily calories from fat. Many experts suggest that fat should be
reduced to 30 percent or less of calories.
Heart Disease
* We know that high blood cholesterol increases your risk
of heart disease, especially as it rises above 200 mg/dl (milligrams
of cholesterol per deciliter of blood). The evidence is clear that
elevated cholesterol in the blood, resulting in part from the foods
we eat and in part from cholesterol made in the body, contributes
to the development of arteriosclerosis, a disorder of arteries that
results in their narrowing and in reduced blood circulation. This
condition can lead to a heart attack or stroke.
We know that blood cholesterol levels are greatly influenced by the
amount of saturated fat and cholesterol found in many of the foods
we eat. These raise blood cholesterol levels. (Of the two,
saturated fat seems to be the major dietary factor which affects
blood cholesterol.)
To reduce your blood cholesterol level, it is important to eat less
saturated fat and cholesterol. Saturated fat and cholesterol are
often found together in foods. Saturated fat in the U.S. diet is
provided primarily by animal products such as the fat in meat,
butter, whole milk, cream, cheese, and ice cream. There are a few
vegetable fats--coconut oil, cocoa butter, palm kernel and palm
oils
which are also high in saturated fat. Cholesterol is found only in
animal products eggs, meat, poultry, fish and dairy products. Plant
foods such as vegetables, grains, cereals, nuts, and seeds do not
contain cholesterol. A few foods are high in cholesterol but
relatively low in fat--for example, egg yolks and liver.
Watch out
for items in the grocery store that are labeled no cholesterol or,
contains no animal fat." They may still contain a large amount
of fat or saturated fat. Examples are peanut butter, solid
vegetable shortening, nondairy creamer, and baked products like
cookies, cakes, and crackers. For
people trying to lose blood cholesterol level, these foods should
be chosen less often.
* We know that
substituting unsaturated fatty acids (which are usually liquid and
usually come from plant sources) for saturated fats can help reduce high
blood cholesterol. Safflower, corn, soybean, olive, and canola
oils are major sources of unsaturated fats. The omega-3 fatty acids
which are found in fish and seafood, may have a favorable effect on
blood fat and reduce the risk of heart disease. No one is sure yet.
* We know that there
is an association between too much sodium in the diet and high
blood pressure in some individuals. Sodium is a mineral that occurs
naturally in some foods and is added to many foods and beverages as salt
or other additives. Most sodium in the American diet comes from
salt. One teaspoon of salt contains about 2 grams of sodium. In
countries where people eat only small amounts of sodium, high blood
pressure is rare. We also know that when some people with high
blood pressure greatly reduce their sodium intake, their blood
pressure will fall. Because Americans generally eat much more sodium
than they need, it is probably best for most people to reduce the
amount of sodium they eat. According to the
National Academy of Sciences, a safe and adequate amount of sodium in
the diet of the average adult is between 1 and 3.3 grams daily.
Some recent studies indicated that the substitution of monosaturated
fats, such as those saturated fats may lower
blood cholesterol.
Cancer
* The National Cancer Institute estimates that about 80 percent
of all cancers may be related to smoking, diet, and the
environment.
* The National Cancer
Institute estimates that about one-third of all cancer deaths may
be related to the foods we eat. Studies at the National Cancer
Institute suggest that eating foods high in fiber may reduce risks
of cancers of the colon and rectum. Adult Americans now eat about
11 grams of fiber daily according to NCI studies.
NCI recommends that Americans increase the
daily amount of fiber they eat to between 20 and 30 grams, with an upper
limit of 35 grams. The NCI also emphasizes the importance of choosing
fiber rich foods, not supplements. Good sources of fiber are whole
grain breads and bran cereals, vegetables, cooked dry peas and
beans, and fruits.
* We know that diets
high in fats of all kinds have been linked to certain cancers,
particularly those of the breast, colon, lining of the uterus, and
prostate gland. Some studies have suggested that fat may act as a
cancer promoter (an agent that speeds up the development of cancer).
* There is some
evidence that diets rich in vitamin A, vitamin C, and beta-carotene
(the plant form of vitamin A) may help reduce the risk of certain
cancers. The evidence we have about vitamins A and C comes from
studies of these vitamins as they are found in foods. That is why
NCI recommends that you eat a variety of foods rich in vitamins
rather than relying on vitamin supplements. Good sources of vitamin
A include yellow-orange vegetables such as carrots, winter squash,
sweet potatoes and pumpkin; and yellow-orange fruits such as
peaches, cantaloupes and mangoes. Sources of vitamin C include
dark-green leafy vegetables such as kale, spinach, and watercress;
broccoli and asparagus; and tomatoes. Some fruit sources of vitamin C
are oranges, lemons, grapefruit, peaches, berries, and cantaloupe.
* There is some
evidence that vegetables in the cabbage family may help protect
against cancer of the colon. These vegetables are also good sources
of fiber, vitamins, and minerals. Cabbage family vegetables include
cabbage, broccoli, cauliflower, Brussels sprouts, collards, kale, turnips,
mustard greens, turnip greens, kohlrabi, watercress and radishes.
Reducing Your Risk of Heart Disease
and Cancer
Based on
what we know, the National Heart, Lung, and Blood Institute and the
National Cancer Institute have joined together to suggest some ways you
may reduce your risks of heart disease and cancer. These suggestions
emphasize the need to eat a variety of foods each day. They also include
some "mealtime strategies" that you can use to plan meals that
avoid too much fat, saturated fat, cholesterol, and sodium, and that
help you to get adequate starch and fiber. These strategies are
consistent with the Department of Agriculture and Department of Health
and Human Services Dietary Guidelines for Americans.
These strategies should encourage you to think about the foods you eat,
how to prepare them, and what food choices you can make when you go
grocery shopping or eat away from home.
The key is
following a Choose More Often approach. It doesn't mean giving up
your favorite foods. It means taking steps to choose more often
foods that are low in fat and high in fiber. For example, if you
enjoy eating steak, choose a low-fat cut such as round steak, trim
off the excess fat, broil it, and drain off the drippings. Pizza?
To try a low-fat version that is rich in fiber, use a whole-grain
English muffin or pita bread topped with part-skim mozzarella, fresh
vegetables, and tomato sauce. And cookies or other desserts? In many
recipes you can reduce the fat, and substitute vegetable oils or
margarine for butter. To increase fiber, use whole wheat flour in place
of white flour.
Here's how
the Choose More Often approach works:
Choose More Often:
Low-fat meat, poultry, fish
Lean cuts of meat trimmed of fat (round tip roast, pork
tenderloin, loin lamb chop), poultry without skin, and
fish, cooked without breading or fat added.
Low-fat dairy products
1 percent or skim milk, buttermilk; low-fat or nonfat
yogurt; lower fat cheeses (part-skim ricotta, pot, and
farmer); ice milk, sherbet.
Dry beans and peas
All beans, peas and lentils--the dry forms are higher in
protein.
Whole grain products
Breads,
bagels, and English muffins made from whole wheat, rye, bran, and
corn flour or meal; whole grain or bran cereals; whole wheat
pasta; brown rice; bulgur.
Fruits and
vegetables
All fruits and vegetables
(except avocados, which are high in fat, but that fat is
primarily unsaturated). For example, apples, pears,
cantaloupe, oranges, grapefruit, pineapple, peaches, bananas,
carrots, broccoli, Brussels sprouts, cabbage, kale, potatoes,
tomatoes, sweet potatoes, spinach, cauliflower, and turnips,
and others.
Fats and oils high in
unsaturates
Unsaturated vegetable oils, such as canola oil, corn oil, cottonseed
oil, olive oil, and soybean oil, and margarine; reduced-calorie
mayonnaise and salad dressings.
To assure
an adequate diet, choose a variety of foods daily including
selections of vegetables; fruits; whole-grain breads and cereals;
low-fat dairy products; poultry, fish, and lean meat, dry beans and
peas. Here are some tips for following the Choose More Often approach in
three important areas: grocery shopping, food preparation, and eating
out.
Grocery Shopping
Focus on variety. Choose a wide selection of
low-fat foods rich in fiber. Include whole grain breads and
cereals, vegetables, fruits, low-fat dairy products, and poultry,
fish, and lean meat. Although the goal is to reduce fat to 30
percent or less of calories, when choosing foods that do contain fat,
try to choose ones that contain primarily unsaturated fats. For example,
choose an unsaturated-rich margarine instead of butter; choose vegetable
oils.
Read food
labels. To help you find foods that are low in fat and cholesterol
and high in fiber, get into the label-reading habit. Many
nutritional labels on packaged foods show the amount of unsaturated and
saturated fatty acids and the amount of cholesterol and fiber they
contain. Check the type of fat on the ingredients list. Is it an animal
fat, coconut or palm kernel oil high in saturated fat? Or, is it corn
or soybean oil high in polyunsaturated fat? Choose a product with
the lowest proportion of saturated fat. The label also tells you
something else about a product. Ingredients are listed in order of
amount from most to least by weight. So, when you buy a breakfast
cereal, for example, choose one that has a whole grain listed first
(such as whole wheat or oatmeal).
Pay attention to sodium. Many processed,
canned, and frozen foods are high in sodium. Cured or processed
meats, cheeses, and condiments (soy sauce, mustard, tartar sauce)
are also high in sodium. Check for salt, onion or garlic salt, and any
ingredient with "sodium" on the label. If the sodium content
is given on the nutritional label, compare products and choose the ones
with lower levels.
Food Preparation
Use small amounts of fat and fatty foods. There
are lots of ways to use less fat. For example, when you sauté or stir-fry,
use only 1/2 teaspoon of fat per serving. When you use margarine,
mayonnaise, or salad dressing, use half as much as usual. And, decrease
portion sizes of other high fat
foods--rich desserts, untrimmed and fatty types of meat, poultry
with skin, and fried foods, especially breaded foods.
Use less
saturated fat. While reducing your total fat intake, substitute
unsaturated fat and oils for saturated fat in food preparation. For
example, instead of butter, use margarine or vegetable oil. One
teaspoon of butter can be replaced with equal portions (or less) of
margarine or 3/4 teaspoon of vegetable oil in many recipes without
affecting the quality. Saturated fat may be reduced even more if you
want to experiment with recipes. Poultry without skin and fish are good
choices because they are often lower in fat and saturated fat than many
meats.
Use
low-fat alternatives. Substitute 1 percent, skim, or reconstituted
nonfat dry milk for whole milk. Use low-fat yogurt, buttermilk, or
evaporated skim milk in place of cream or sour cream. Try
reduced-calorie mayonnaise and salad dressing in place of regular.
Choose
lean meat. When you buy meat, choose lean cuts such as beef round, pork
tenderloin, and loin lamb chops. Be sure to trim all visible fat from
meat and poultry and remove poultry skin.
Use
low-fat cooking methods. Bake, steam, broil, microwave, or boil
foods rafter than frying. Skim fat from soups and gravies.
Increase fiber. Choose whole grain breads and
cereals. Substitute whole grain flour for white flour. Eat
vegetables and fruits more often and have generous servings.
Whenever possible, eat the edible fiber-rich skin as well as the
rest of the vegetable or fruit.
Use herbs,
spices, and other flavorings. For a different way to add flavor to
meals, try lemon juice, basil, chives, allspice, onion, and garlic
in place of fats and sodium. Try new recipes that use less fat or
sodium-containing ingredients, and adjust favorite recipes to reduce fat
and sodium.
Eating Out
Choose the restaurant carefully. Are there
low-fat as well as high-fiber selections on the menu? Is there a
salad bar? How are the meat, chicken, and fish dishes cooked? Can you
have menu items broiled or baked without added fat instead of fried? These
are important things to know before you enter a restaurant--fast
food or otherwise. Seafood restaurants usually offer broiled, baked, or
poached fish, and you can often request butter and sauces on the side.
Many steak houses offer small steaks and have salad bars.
Try ethnic
cuisines. Italian and Asian restaurants often feature low-fat
dishes. though you must be selective and alert to portion size. Try a
small serving of pasta or fish in a tomato sauce at an Italian
restaurant. Many Chinese, Japanese, and Thai dishes include plenty of
steamed vegetables and a high proportion of vegetables to meat. Steamed
rice, steamed noodle dishes, and vegetarian dishes are good choices too.
Ask that the chef cook your food without soy sauce or salt to decrease
sodium. Some Latin American restaurants feature a variety of fish and
chicken dishes that are low in fat.
Make sure you get what you want Here are just a
few things you can do to make sure you're in control when you eat out.
Ask how dishes are cooked. Don't hesitate to request that one food be
substituted for another. Order a green salad or baked potato in place of
French fries or order fruit, fruit ice, or sherbet instead of ice cream.
Request sauces and salad dressings on the side and use only a small
amount. Ask that butter not be sent to the table with your rolls. If
you're not very hungry, order two low-fat appetizers rather than an
entire meal, split a menu item with a friend, get a doggie-bag to take
half of your meal home, or order a half-size portion. When you have
finished eating, have the waiter clear the dishes away so that you can
avoid post meal nibbling.
Mealtime Strategies
We've given you some basic information on fat,
fiber, and sodium. And, we've provided some tips on decreasing fat, saturated
fat, cholesterol and sodium; and increasing fiber. But, how do you
put it all together when it comes to breakfast, lunch, and dinner? These
mealtime strategies should help.
Breakfast
Strategy
#1--Choose fruit more often. Just a few great choices in the fruit
family are: cantaloupe, grapefruit, strawberries, oranges, bananas,
pears, and apples.
Strategy
#2--Choose whole-grain cereals and products more often. Examples are
whole wheat or bran breads, bagels, and cereal.
Strategy #3--Try making pancakes and waffles
with whole wheat flour instead of white flour and one whole egg and one
egg white rafter than two whole eggs. For a low-fat topping with fiber,
try applesauce, apple butter and cinnamon, or fruit and low-fat plain
yogurt.
Strategy
#4--Fruit juice and skim milk are familiar breakfast drinks. For an
extra boost in the morning, why not try a fruit smoothie made from
juice, fruit and nonfat plain yogurt blended together. Other nonfat
choices are seltzer water, coffee, and tea.
These
breakfast choices are sound nutrition choices because they are not
only low in fat and cholesterol but also provide fiber, vitamins,
and minerals. Some foods that you should choose less often are
sausage, bacon, butter, whole milk and cream (including commercial
nondairy creamer). These foods are high in saturated fat and
cholesterol.
Lunch
Strategy #1--Try a fiber-rich bean, split pea,
vegetable,
or minestrone soup. Use commercially canned and frozen soups and cream
soups less often--they can be high in sodium and fat. If you make your
own soup, use broth or skim milk to keep the fat content low.
Strategy
#2--Have a bean salad or mixed greens with plenty of vegetables. For
fiber include some vegetables like-- carrots, broccoli, cauliflower, and
kidney or garbanzo beans. For a low-fat dressing, try lemon juice or a
reduced-calorie dressing. If you use regular dressing, use only a
very small
amount.
Strategy
#3--Try sandwiches made with water-packed tuna, sliced chicken, turkey,
lean meat, or low-fat cheese, and use whole-grain bread or pita bread.
To decrease fat, use reduced-calorie mayonnaise, or just a small amount
of regular mayonnaise, or use mustard. Mustard contains no fat.
Strategy #4--For dessert, have fresh fruit,
low-fat yogurt, or a frozen fruit bar.
Strategy
#5--Fruit juice and skim milk are good beverage choices. Club soda
with a twist of lemon or lime, hot or iced tea with lemon, or
coffee without cream are refreshing drinks.
At lunch,
try to eat these foods less often: processed luncheon meats, fried
meat, chicken, or fish; creamy salads, french fries and chips,
richer creamy desserts, high-fat baked goods, and high-fat cheeses such
as Swiss, cheddar, American, and Brie.
Dinner
Strategy
#1--Eat a variety of vegetables. To increase
variety, try some that might be new to you, such as those from the
cabbage family (broccoli, Brussels sprouts, cauliflower, and cabbage),
dark-green leafy vegetables (spinach and kale), and yellow-orange
vegetables (winter squash and sweet potatoes). For old favorites, like
peas and green beans, skip the butter and sprinkle with lemon juice or
herbs. Or, how about a baked potato, with the skin, and topped with
low-fat yogurt and chives, tomato salsa, or a small amount of low-fat
cheese?
Strategy
#2--Try whole wheat pasta and casseroles made with brown rice,
bulgur, and other grains. If you are careful with preparation,
these dishes can be excellent sources of fiber and low in fat. For
example, when milk and eggs are ingredients in a recipe, try using
1 percent or skim milk, reduce the number of egg yolks and replace
with egg whites. Here are some ideas for grain-based dishes:
--Whole wheat
spaghetti with fresh tomato sauce;
--Whole wheat macaroni and chickpea stew in tomato sauce;
--Tuna noodle casserole, using water-packed tuna (or
rinsed, oil-packed tuna), skim milk, and fresh mushrooms or sliced
water chestnuts;
--Turkey, broccoli and brown rice casserole using skim milk
and egg whites;
--Eggplant lasagna, made with broiled eggplant and part-
skim mozzarella or ricotta cheese.
Strategy
#3--Substitute whole-grain breads and rolls for white bread.
Strategy
#4--Choose main dishes that call for fish,
chicken, turkey or lean meat. Don't forget to remove the skin and
visible fat from poultry and trim the fat from meat. Some good low-fat
choices are:
Red snapper stew;
Flounder or sole florentine (make the cream sauce with skim milk);
Salmon loaf (use skim milk, rolled oats, and egg whites);
Baked white fish with lemon and fennel;
Chicken cacciatore Italian-style (decrease the oil in the recipe);
Chicken curry served over steamed
wild rice (choose a recipe that requires little or no fat;
"sauté" the onions in chicken broth instead of butter);
Light beef stroganoff with
well-trimmed beef round steak and buttermilk served over noodles;
Oriental pork made with lean pork
loin, green peppers and pineapple chunks served over rice.
Strategy
#5--Choose desserts that give you fiber but little fat such as:
Baked apples or bananas, sprinkled with cinnamon;
Fresh fruit cup;
Brown bread or rice pudding made with skim milk;
Oatmeal cookies (made with margarine or vegetable oil; add raisins).
For many,
the end of the workday, represents a time to relax, and dinner can
be a light meal and an opportunity to decrease fat and cholesterol.
Snacks
Strategy #1--Try a raw vegetable platter made
with a variety of vegetables. Include some good fiber choices: carrots,
snow peas, cauliflower, broccoli, green beans.
Strategy
#2--Make sauces and dips with nonfat plain yogurt as the base.
Strategy #3--Eat more fruit. Oranges,
grapefruit, kiwi, apples, pears, bananas, strawberries and
cantaloupe are all good fiber sources. Make a big fruit salad and
keep it on hand for snacks.
Strategy
#4--Plain, air-popped popcorn is a great low-fat snack with fiber.
Watch out! Some prepackaged microwave popcorn has fat added. Remember to
go easy on the salt or use other seasonings.
Strategy
#5--Instead of chips, try one of these low-fat
alternatives that provide fiber: toasted shredded wheat Squares
sprinkled with a small amount of grated Parmesan cheese, whole-grain
English muffins, or toasted plain corn tortillas.
Strategy
#6--When you are thirsty, try water, skim milk, juice, or club soda
with a twist of lime or lemon.
The
National Heart, Lung, and Blood Institute and the National Cancer
Institute are committed to promoting good health and reducing the
loss of life from heart disease and cancer. You can help. By using
the ideas in this booklet, trying recipes that have been modified
