Nutrition
Having a healthy
diet is sometimes easier said than done. Between
work or school, and family you are probably
balancing a hundred things at once. Having a
healthy meal sometimes falls last on your list.
But you should know that it isn't hard to make
simple changes to improve your diet. A little
learning and planning can help you find a diet
to fit your lifestyle.
Why Have a Healthy Diet?
Obesity in
Americans is on the rise. About 35 percent of us
weigh more than we should for good health.
Obesity is measured with a body mass index
(BMI), which shows the relationship of weight to
height. As your body mass increases, so does
your risk for serious health problems, such as
type 2 diabetes, high blood pressure, stroke,
heart disease, and some cancers. Your body mass
is affected by how much physical activity you
do, your diet, and your genes. So having a
healthy diet is one of the most important things
you can do to help your overall health. If you
burn as many calories as you take in, your
weight remains the same. If you take in fewer
calories than you burn, you will lose weight. So
make sure the foods you eat are healthy ones
that will work hard for your body.
Basic Steps to a Healthy Diet
There are some
basic steps to good nutrition that you can
easily build into your lifestyle. It doesn't
hurt that these steps also help you reduce your
risk for heart disease — the #1 killer of men.
You can do this by having a diet that:
- helps you
either lose weight or keeps your body mass index
(BMI) in the "healthy" range
- is balanced
overall, with foods from all food groups, with
lots of delicious fruits, vegetables, whole
grains, and fat-free or low-fat milk and milk
products.
- is low in
saturated fat, trans fat, and cholesterol
(consume less than 10 percent of your daily
calories from saturated fat, and less than 300
mg/day of cholesterol, and keep trans fatty acid
consumption as low as possible). Foods low in
saturated fat include fruits, vegetables, whole
grain foods, and low-fat or nonfat dairy
products. Try to avoid commercially fried and
baked goods such as crackers and cookies. Keep
total fat intake between 20 to 35 percent of
calories, with most fats coming from sources of
polyunsaturated and monounsaturated fatty acids,
such as fish, nuts, and vegetable oils.
- includes a
variety of grains daily, especially whole
grains, a good source of fiber.
- includes a
variety of fruits and vegetables (two cups of
fruit and 2 1/2 cups of vegetables per day are
recommended for a 2,000 calorie diet).
- has a small
number of calories from added sugars (like in
candy, cookies, and cakes)
- has foods
prepared with less sodium or salt (aim for no
more than 2,300 milligrams of sodium per day, or
about one teaspoon of salt per day). You can
choose low-sodium foods, which will also help
lower your cholesterol, such as fruits,
vegetables, whole grains, low-fat or nonfat
dairy products, and moderate amounts of lean
meat. To flavor your food, reach for herbs and
spices rather than high-sodium table salt. Be
sure to read the labels of seasoning mixes
because some contain salt.
- if you drink
alcoholic beverages, does not include more than
two drinks per day (one drink per day for
women).
- if you want to
improve your heart health, includes at least two
servings of fish per week (especially fatty fish
like salmon and lake trout) because they are
high in omega-3 fatty acids, which may help
lower blood cholesterol. You also can eat
omega-3 fatty acids from plant sources, such as
from tofu, soybeans, canola, walnuts, and
flaxseed (these contain alpha-linolenic acid, a
less potent form of omega-3 fatty acid).
Know
Your Fats
There are
different kinds of fats in our foods. Some can
hurt our health, while others aren't so bad!
Some are even good for you! Here's what you need
to know:
- Monounsaturated
fats (canola, olive and peanut oils, and
avocados) and polyunsaturated fats (safflower,
sesame, sunflower seeds, and many other nuts and
seeds) don't raise your LDL ("bad") cholesterol
levels but can raise your HDL ("good")
cholesterol levels. To keep healthy, it is best
to choose foods with these fats.
- Saturated fat,
trans fatty acids, and dietary cholesterol raise
your LDL ("bad") blood cholesterol levels, which
can lead to heart disease. Saturated fat is
found mostly in food from animals, like beef,
veal, lamb, pork, lard, poultry fat, butter,
cream, whole milk dairy products, cheeses, and
from some plants, such as tropical oils.
Tropical oils include coconut, palm kernel, and
palm oils that are found in commercial cakes,
cookies, and salty snack foods. Unlike other
plant oils, these oils have a lot of saturated
fatty acids. Some processed foods (such as
frozen dinners and canned foods) can be quite
high in saturated fat-it' s best to check
package labels before purchasing these types of
foods.
-Trans fatty
acids (TFAs) are formed during the process of
making cooking oils, margarine, and shortening
and are in commercially fried foods, baked
goods, cookies, and crackers. Some are naturally
found in small amounts in some animal products,
such as beef, pork, lamb, and the butterfat in
butter and milk. In studies, TFAs tend to raise
our total blood cholesterol. TFAs also tend to
raise LDL ("bad") cholesterol and lower HDL
("good") cholesterol. At this time, TFAs are not
listed on nutrition labels, but that will soon
change. Although it might take a couple of years
to begin seeing it, the Food and Drug
Administration (FDA) is now asking food
manufacturers to begin labeling TFA content. And
some food manufacturers are announcing they are
taking TFAs out of their food.
Portion Control
Sizes for
everything from bananas to soft drinks have
gotten larger in the past 20 years. It's not
enough to eat the right kinds of food to
maintain a healthy weight or to lose weight.
Eating the right amount of food at each meal is
just as important. If you are a healthy eater,
it is possible to sabotage your efforts by
eating more than the recommended amount of food.
A serving is a specific amount of food, and it
might be smaller than you realize. Here are some
examples:
- A serving of
meat (boneless, cooked weight) is two to three
ounces, or roughly the size of the palm of your
hand, a deck of cards, or an audiocassette tape.
-A serving of
chopped vegetables or fruit is 1/2 cup, or
approximately half a baseball or a rounded
handful.
- A serving of
fresh fruit is one medium piece, or the size of
a baseball.
- A serving of
cooked pasta, rice, or cereal is 1/2 cup, or
half a baseball or a rounded handful.
- A serving of
cooked beans is 1/2 cup, or half a baseball or a
rounded handful.
- A serving of
nuts is 1/3 cup, or a level handful for an
average adult.
- A serving of
peanut butter is two tablespoons, about the size
of a golf ball.
No matter which
diet you choose, be sure to talk with your
doctor before starting any type of eating plan.
You might want to ask your doctor for a referral
to a registered dietician (RD) who can help you.
You might also want to enlist the help of a
family member or friend to give you support and
help you stay on track. Try to have some fun
learning new recipes and different ways to cook!
Making Sense of Nutrition Terms
We see these terms all the time,
but what do they mean?
(These definitions are based on
one - serving of a food. If you
eat more than one serving, you
will go over these levels of
calories, fat, cholesterol, and
sodium.)
Calorie-free:
fewer than 5
calories
Low calorie: 40 calories or
fewer
Reduced calorie: at least 25%
fewer calories than the regular
food item has
Fat free: less than ½ gram of
fat
Low fat: 3 grams of fat or fewer
Reduced fat: at least 25% less
fat than the regular food item
has
Cholesterol free: fewer than 2
milligrams cholesterol and no
more than 2 grams of saturated
fat
Low cholesterol: 20 milligrams
or fewer cholesterol and 2 grams
or less saturated fat
Sodium free: fewer than 5
milligrams sodium
Very low sodium: fewer than 35
milligrams sodium
Low sodium: fewer than 140
milligrams sodium
High fiber: 5 grams or more fiber
