Developing healthy eating
habits isn't as confusing or as restrictive as many people imagine.
The first principle of a healthy diet
is simply to eat a wide variety of foods. This is important because
different foods make different nutritional contributions.
Secondly,
fruits, vegetables, grains, and legumes—foods high
in complex carbohydrates, fiber, vitamins, and minerals, low in
fat, and free of cholesterol—should make up the bulk of the
calories you consume.
The rest should come from low-fat dairy products,
lean meat and poultry, and fish.
You should also try to maintain
a balance between calorie intake and calorie expenditure—that
is, don't eat more food than your body can utilize. Otherwise,
you will gain weight. The more
active you are, therefore, the more you can eat and still maintain
this balance.
Following these three basic steps doesn't mean that
you have to give up your favorite foods. As long as your overall
diet is balanced
and rich in nutrients and fiber, there is nothing wrong with
an occasional cheeseburger. Just be sure to limit how frequently
you
eat such foods, and try to eat small portions of them.
You can also
view healthy eating as an opportunity to expand your range of choices
by trying foods—especially vegetables, whole
grains, or fruits—that you don't normally eat. A healthy
diet doesn't have to mean eating foods that are bland or unappealing.
The
following basic guidelines are what you need to know to construct
a healthy
diet.
1 Eat plenty of high-fiber
foods—that is, fruits, vegetables, beans,
and
whole grains. These are the "good" carbohydrates—nutritious,
filling, and relatively low in calories. They should supply the 20 to 30 grams
of dietary fiber you need each day, which slows the absorption of carbohydrates,
so there’s less effect on insulin and blood sugar, and provides other
health benefits as well. Such foods also provide important vitamins, minerals,
and phytochemicals
(plant chemicals essential to good health).
2 Make sure to include
green, orange, and yellow fruits and vegetables—such
as broccoli, carrots, cantaloupe, and citrus fruits. The antioxidants and
other nutrients in these foods may help protect against developing
certain types
of cancer and other diseases. Eat five or more servings a day.
3 Limit your
intake of sugary foods, refined-grain products such as white bread,
and salty snack foods. Sugar, our No.1 additive, is added to a
vast
array of
foods. Just one daily 12-ounce can of soda (160 calories) can add up to 16
pounds over the course of a year. Many sugary foods are also high in fat,
so they’re
calorie-dense.
4 Cut down on animal
fat. It’s rich in saturated fat,
which boosts blood cholesterol levels and has other adverse health effects.
Choose lean meats, skinless
poultry, and nonfat or low-fat or nonfat dairy products.
5 Cut way down
on trans fats, supplied by hydrogenated vegetable oils used in
most processed foods in the supermarket and in many fast foods.
6 Eat more
fish and nuts, which contain healthy unsaturated fats. Substitute
olive or canola oil for butter or stick margarine.
7 Keep portions
moderate, especially of high-calorie foods. In
recent years serving sizes have ballooned, particularly in restaurants.
Choose a starter
instead of
an entrée, split a dish with a friend, and don’t order supersized
anything.
8 Keep your cholesterol
intake below 300 milligrams per day. Cholesterol is found only
in animal products, such as
meats, poultry, dairy products,
and
egg yolks.
9 Eat a variety of foods.
Don't try to fill your nutrient requirements by eating the same
foods day in, day out.
It is possible that not every
essential
nutrient
has been identified, and so eating a wide assortment of foods helps
to ensure that you will get all the necessary nutrients. In addition,
this
will limit
your exposure to any pesticides or toxic substances that may be present
in one particular
food.
10 Maintain an adequate
calcium intake. Calcium is essential for strong bones and teeth.
Get your calcium from low-fat
sources,
such as skim
milk and low-fat
yogurt. If you can't get the optimal amount from foods, take supplements.
11 Try
to get your vitamins and minerals from foods, not from supplements.
Supplements cannot substitute for a healthy diet, which supplies nutrients
and other compounds
besides vitamins and minerals. Foods also provide the "synergy" that
many nutrients require to be efficiently used in the body.
12 Maintain
a desirable weight. Balance energy (calorie) intake with energy output.
Exercise and other physical activity are essential.
13 If you drink
alcohol, do so in moderation. That is one drink a day for women,
two a day for men. A drink is defined as 12 ounces
of beer,
4 ounces
of wine,
or 1.5 ounces of 80-proof spirits. Excess alcohol consumption leads
to a variety of health problems. And alcoholic beverages can add
many calories
to your diet
without supplying nutrients.
