What are the keys to a healthy diet?
Your daily diet and physical activity are very important to
your health--how you feel today and in the future. The
three keys to a healthy diet are:
- Make smart choices from every food group: fruits,
vegetables, grains, milk products, and meat (or other
protein-rich foods).
- Find a balance between how much food you eat and how
much physical activity you have.
- Get the most nutrition out of your calories.
What foods do I need?
The best way to give your body the balanced nutrition it
needs is by eating a variety of nutrient-packed foods every
day. Just be sure to stay within your daily calorie needs.
A healthy eating plan is one that:
- Emphasizes fruits, vegetables, whole grains, and fat-free
or low-fat milk and milk products.
- Includes lean meats, poultry, fish, soy protein, beans,
eggs, and nuts.
- Is low in saturated fats, trans fats, cholesterol, salt
(sodium), and added sugars.
Fruits
Eat a variety of fruits--whether fresh, frozen, canned, or
dried--rather than fruit juice for most of your fruit
choices. (Fruit juice is higher in calories and sugar and
does not have as much fiber as whole fruits.) For a
2000-calorie diet, you should have 2 cups of fruit each day (for
example, 1 small banana, 1 large orange, and 1/4 cup of
dried apricots).
Vegetables
A 2000-calorie diet should include 2 and 1/2 cups of
vegetables each day. Eat:
- more green vegetables, such as broccoli, cabbage, and
dark leafy greens
- orange vegetables, such as carrots, sweet potatoes,
pumpkin, and winter squash
- beans and peas, such as pinto beans, kidney beans, black
beans, garbanzo beans, split peas, and lentils.
Whole Grains
Eat at least 3 ounces of whole-grain cereals, breads,
crackers, rice, or pasta every day. One ounce is about 1
slice of bread, 1 cup of cereal, or a half cup of cooked
rice or pasta.
Whole grains are good sources of fiber and other important
nutrients. As well as helping to prevent constipation,
fiber can slow sugar absorption and help lower cholesterol
levels. You should try to have 14 grams of fiber for every
1000 calories in your diet. Whole-grain sources of fiber
are whole wheat, bran, whole rye, oats and oatmeal,
whole-grain corn, and brown or wild rice. Other sources of fiber
are flax seeds, nuts, vegetables, fruits, and beans.
Milk products
Get 3 cups of low-fat or fat-free milk--or an equivalent
amount of low-fat yogurt or low-fat cheese (1 and 1/2 ounces
of cheese equals 1 cup of milk)--every day. If you have
trouble digesting milk, choose lactose-free milk products or
calcium-fortified foods and beverages.
Protein
Choose lean meats and poultry. Bake, broil, or grill the
meats instead of frying them. Get some of your protein
from other foods, such as fish, beans, peas, nuts, and
seeds. Try to use meat as a side dish rather than a main
course. You can decrease the amount of meat you eat by
including it in a casserole or stew, using the meat as a
flavoring for the main dish.
It is possible to have a healthy diet without eating meat.
Vegetarians do have to be careful to make sure they get
complete protein and enough iron.
Most packaged foods have a Nutrition Facts label. Use this
tool to make healthy food choices quickly and easily. Use
the % Daily Value (DV) column when possible: 5% DV or less
is low, and 20% DV or more is high. Try these tips:
- Keep these low: saturated fats, trans fats, cholesterol,
and sodium.
- Get enough of these: potassium, fiber, vitamins A and C,
calcium, and iron.
Look at the serving size listed on the label and think
about how many servings you are actually eating. If you
double the servings you eat, you double the calories and
nutrients, including the % DVs. Look at the calories on
the label and compare them with the nutrients you are also
getting to decide whether the food is worth eating.
Remember that when one serving of a single food item has
over 400 calories per serving, it is high in calories.
The foods to limit
Some foods contain very little nutritional value or have
ingredients that can cause disease. Eating healthy doesn't
mean giving up all sweets, salt, and snacks. It means
eating such foods in moderation. You should limit
saturated fats, trans fats, cholesterol, sodium, and added
sugars in your diet. Reading the Nutrition Facts label on
foods can help you do this.
Fats
Look for foods low in saturated fats, trans fats, and
cholesterol to help reduce the risk of heart disease.
Examples of foods that contain saturated fat include
butter, cheese, some margarines, shortening, tropical oils
such as coconut and palm oil, and the fats in meat and
poultry skin. Some margarines and many processed foods
contain trans, or hydrogenated, fats. Cholesterol is a
substance found in animal products such as meat, eggs,
dairy products, and baked goods made with eggs and milk.
Most of the fats you eat should be polyunsaturated and
monounsaturated fats. Healthy oils to use are canola, soy,
olive, peanut, or corn oil. Try not to eat foods
containing tropical oils such as palm or coconut oil. Fats
should contribute no more than 20% to 35% of your daily
calories.
Salt
Choose and prepare foods and beverages with little salt
(sodium). An average healthy person should have at least
500 mg (milligrams) of sodium a day but no more than 2300
mg a day. Research shows that eating less than 2300
milligrams of sodium (about 1 tsp of salt) per day may
reduce the risk of high blood pressure. Most of the sodium
people eat comes from processed and fast foods, not from
the salt shaker. Taste food before you add salt to it at
the table. Try adding other spices or herbs to the foods
you cook and eat instead of salt. Also look for foods high
in potassium, which counteracts some of sodium's effects on
blood pressure.
Sugars
Choose foods and beverages low in added sugars. Sugars
supply a lot of calories with few, if any, nutrients. Read
the ingredient list for packaged foods and make sure that
added sugars are not one of the first few ingredients.
Some names for added sugars are sucrose, glucose, corn
syrup, maple syrup, and fructose.
Alcohol
If you choose to drink alcohol, do so in moderation.
Moderate drinking means up to 1 drink a day for women and up
to 2 drinks for men. A drink equals 12 ounces of regular
beer, 5 ounces of wine, or 1 and 1/2 ounces of 80-proof
distilled spirits. Remember that alcoholic beverages have
calories but are low in nutritional value. Generally,
anything more than moderate drinking can be harmful to your
health. Some people, or people in certain situations,
should not drink at all.
Pay attention to the calories in your diet
There is a right number of calories for you to eat each day.
This number depends on your age, activity level, and whether
you are trying to gain, maintain, or lose weight. You could
get all the calories you need from a few high-calorie items,
but chances are you won't get all of the vitamins and
nutrients your body needs to be healthy. Choose the most
nutritionally rich foods you can from each food group each
day: foods packed with vitamins, minerals, fiber, and other
nutrients but lower in calories. Pick foods like fruits,
vegetables, whole grains, and fat-free or low-fat milk and
milk products more often.
If you eat 100 more food calories a day than you burn, you
will gain about 1 pound in a month. That's about 10 pounds
in a year. The bottom line is that, if you want to maintain
your weight, the number of calories you eat every day should
equal the number of calories you burn. If you want to lose
weight, you need to eat fewer calories and increase your
physical activity.
Be physically active.
Regular physical activity is important for your overall
health and fitness. It also helps you control body weight
by balancing the calories you take in as food with the
calories you burn each day.
- Be physically active for at least 30 minutes most days of
the week.
- Increasing the intensity or the amount of time that you
are physically active can have even greater health
benefits and may be needed to control body weight. About
60 minutes of moderate exercise a day may be needed to
prevent weight gain and 90 minutes a day to lose weight.
Moderate aerobic exercise is generally defined as
requiring about the energy it takes to walk 2 miles in 30
minutes. Follow your health care provider's
recommendations.
