"I have trouble chewing."
"Food just doesn’t taste the same anymore."
"I don’t have a car to go shopping."
"It’s hard to cook for one person."
"I’m just not that hungry anymore."
Is one of these a reason you
are not eating well now? Food provides energy and nutrients that your
body needs to stay healthy. Nutrients include proteins, carbohydrates, fats,
vitamins, minerals, and water. As you grow older, you may need less energy
from what you eat. But, you still need just as many of the nutrients in food.
Nutrition experts can recommend what the average older person needs to eat,
but you should also check with your doctor or a registered dietitian, a specialist
trained in nutrition. This is especially true if you have a health problem
that limits what you should eat. They can help you plan meals that will include
the healthy foods you need without the foods you should avoid.

Choose many different healthy
foods. Pick those that are lower in fat, especially saturated fat (mostly
in foods that come from animals), and cholesterol. Eat or drink only small
amounts of sugary or salty foods, and alcoholic drinks, if you drink them
at all. Avoid "empty calories" as much as you can. These are foods like sodas,
potato chips, and cookies that have a lot of calories, but not many nutrients.
Calories are
a way to measure the energy you get from food. If you eat more calories
than your body needs, you could gain weight. If you are not active, choose
lower calorie foods and eat the smallest number of servings suggested for
each of the five food groups (See below). If you are active, you should eat
more servings for more calories. The calorie counts for most packaged foods
are listed in the Nutrition Facts part of the label or package.

The U.S. Department of Agriculture
(USDA) has developed the Food Guide Pyramid to help you make healthy food
choices. There are five major food groups. Every day you should try to eat
the suggested number of servings from each group. If you can’t do that,
at least try to eat something from each group each day. Lower fat choices
are best.
Make sure you eat vegetables, fruits, and whole-grain foods. The food groups
are:
Grains—6-11 servings; one
serving is:
- One roll, slice of bread, or small
muffin,
- 1/2 bagel or English muffin,
- 1/2 cup of cooked rice or pasta,
- 1/2 cup of cooked cereal, or
- about 1 cup (1 oz.) of ready-to-eat
cereal.
Vegetables—3-5 servings;
one serving is:
- 1/2 cup of chopped raw or cooked
vegetables, or
- 1 cup of leafy raw vegetables.
Fruits—2-4 servings; one
serving is:
- 1 medium piece of fruit or melon
wedge,
- 3/4 cup of juice,
- 1/2 cup of canned fruit, or
- 1/4 cup of dried fruit.
Milk, yogurt, and cheese—2-3 servings (3 for
people over 50); one serving is:
- 1 cup of milk or yogurt, or
- 1-1/2 to 2 ounces of cheese.
One cup of soup made with
milk, 1/2 cup of pudding from "scratch" or a mix, or 1 cup of cottage cheese
counts as half a serving.
Meat, poultry, fish, dry beans, eggs, and nuts—2-3
servings (to equal 5 to 7 ounces of lean meat, poultry, or fish);
one serving is:
- 2 to 3 ounces of cooked lean meat,
poultry, or fish,
- 1/2 cup of tuna fish, or
- 1/2 cup of cooked beans or tofu,
1 egg, 1/3 cup of nuts, or 2 tablespoons of peanut butter—each of
which can count as one ounce of meat.
Some other tips:
- Each day eat only small amounts
of fats, oils, and sweets.
- Remember, when counting servings,
that there may be more than one "Food Pyramid serving" of a food on your
plate. For example, a sandwich made with two slices of bread is two servings
of grain products.
- Sometimes manufacturers put more
than one serving in a package or bottle.

Does your favorite chicken
dish taste different? Does Aunt Molly’s pea soup suddenly seem to need
salt? The flavor of the food is probably the same as always. With age your
sense of taste and sense of smell may change. This affects how foods taste.
They may
seem to have lost flavor. You may not be able to smell if foods have gone
bad. You might want to date foods in your refrigerator to keep yourself from
eating foods that are no longer fresh. If in doubt, throw it out.
There are other reasons food
may not taste the same. Some medicines can change your sense of taste or make
you feel less hungry. Maybe you have slowed down a bit, so your body needs
fewer calories. Maybe chewing is difficult because your dentures need to be
adjusted or your teeth or gums need to be checked. You might want to pick
softer foods to eat.

Not just water. You need to
drink plenty of liquids like water, juice, milk, and soup. Aim for eight 8-ounce
glasses a day. You have to replace the fluids you lose every day. But, check
with your doctor if he or she has told you to limit how much you drink.
Don’t wait until you
feel thirsty to start drinking. With age you may lose some of your sense of
thirst. In addition, medicine can sometimes cause you to lose fluids. If you
are drinking enough, your urine will be pale yellow. If it is a bright or
dark yellow, you need to drink more liquids. If the color still does not change,
talk to your health care provider.
Do you have a urinary control
problem? If your answer is yes, don’t stop drinking a lot of liquid.
But, talk to your doctor for help with your urinary control problem.

Dietary fiber is found in
foods that come from plants— fruits, vegetables, beans, nuts, seeds,
brown rice, and whole grains, such as oat, barley, wheat, corn, and rice bran.
It is the part of plant foods that your body cannot digest. Eating more fiber
may prevent intestinal problems like constipation, diverticulosis, and diverticulitis.
It may also lower cholesterol and blood sugar and help you have regular bowel
movements.
Some nutrition experts think
adults should eat 20 to 35 grams of fiber each day. If you are not used to
eating a lot of fiber, add extra sources of fiber to your diet slowly to avoid
stomach problems. The best source of this fiber is food, rather than dietary
supplements. When adding fiber, remember:
- Eat cooked dry beans, peas, and
lentils often.
- Leave skins on your fruit and vegetables
when possible.
- Choose whole fruit over fruit juice.
- Eat whole-grain breads and cereals.
- Drink lots of fluids to keep the
fiber moving through your intestines.

Salt (sodium chloride) is
the most common way people get sodium. Sodium is naturally present in most
foods, and salt is added to many canned and prepared foods. The body uses
sodium to keep the blood, muscles, and nerves healthy, but too much is not
good. Most people eat a lot more sodium than they need.
Each day you should eat no
more than 2400 mg of sodium. This is about one teaspoon of table salt.
It includes all the sodium you get in your food and drink, not just what you
add when cooking or eating. If your doctor tells you to use less salt, try
to cut back on salty foods like processed meats and mustard. Use spices, herbs,
and lemon juice to add flavor to your food.

Fat in your diet provides
energy and certain vitamins. Too much fat, especially saturated fat, can be
bad for your heart and blood vessels and can lead to heart disease. Saturated
fats often come from animal sources. They tend to be solid at room temperature,
rather than liquid. Also, fat is high in calories. It should make up no more
than 30 percent of your total calories—53 grams of fat if you are trying
to eat 1600 calories a day. Some examples of fat content are:
- a 3-ounce broiled, extra-lean hamburger
patty has about 14 grams,
- a hard-boiled egg has 5 grams, and
- a teaspoon of butter or margarine
has 4 grams.
To lower the fat in your diet:
- Choose lean cuts of meat, fish,
or poultry (with the skin removed).
- Trim off any extra fat before cooking.
- Use low-fat dairy products and salad
dressings.
- Use non-stick pots and pans, and
cook without added fat.
- If you do use fat, use either an
unsaturated vegetable oil or a nonfat cooking spray.
- Broil, roast, bake, stir-fry, steam,
microwave, or boil foods. Avoid frying them.
- Season your foods with lemon juice,
herbs, or spices, instead of butter.

Plan your meals in advance.
Check your supply of staples like flour, sugar, rice, and cereal. Make a list
of what you need. Keep some canned or frozen fish, meat, fruits, vegetables,
dinners, and soups on hand. These are handy when you do not feel like cooking
or cannot
go out. Powdered nonfat dry milk, canned evaporated milk, and ultra-pasteurized
milk in a carton can be stored easily.
Think about how much of a
product you will use. A large size may be cheaper per unit, but it is not
a bargain if you end up throwing much of it away. Share large packages with
a friend. Frozen vegetables sold in bags save money because you can use small
amounts while keeping the rest frozen. If a package of meat or fresh
produce is too large, ask a store employee to repackage it in a smaller size.
Learn to read food package
labels. There you will find a list of ingredients. The first one listed is
present in the food in the largest amount. The ones that follow are present
in smaller and smaller amounts. Look at "Nutrition Facts" for the calories,
protein, carbohydrate, fat, sodium, fiber, vitamin, and mineral amounts per
serving. It also suggests a serving size for
comparing foods. There may be an expiration or "use by" date on the label
or container. At first, reading labels will add some time to your shopping
trip. Soon you will learn which products are best for you.

Here are some ways to keep
your food costs down:
- Plain (generic) labels, if available,
or store brands are usually cheaper than name brands.
- Plan your menu around items on sale.
- Prepare more of the foods you enjoy,
and quickly refrigerate the leftovers to eat in a day or two.
- Or, divide leftovers into individual
servings. Write the contents and date on each package, and freeze to use
within a few months.
- Share meal preparation and costs
with a friend.
- Plan a "pot-luck" dinner where everyone
brings a prepared dish.
The federal government provides
food stamps to help people with low incomes buy groceries. If you think you
are eligible, check with a local food stamps office or area agency
on aging. Also check with your local area agency on aging or tribal organization
for the nearest senior center or nutrition site. You may be able to enjoy
free or low-cost meals for older people at a community center, church, or
school. These meals offer good food and a chance to be with other people.
Home delivered meals are available for people who are homebound.
