As you age, you should realize that aging started the day we were born. Our society is living longer than ever before. In the United States, the older population—persons 65 years or older—numbered 35.9 million in 2003 (the latest year for which data are available). Throughout our entire life course, our minds and our bodies constantly undergo changes. When we consider aging as affecting us on many levels, we are exploring aging through a biopsychosocial lens.

For example, on a biological level, our major organs—heart, lungs, eyes, ears, and brain—lose a portion of their functioning ability as we grow older. On a psychological level, changes in our short-term memory may decrease our ability to recall information that we have just heard. Aging also affects our social environment. Upon retirement, friends may elect to move to a warmer climate or closer to family or friends. Friendship patterns may change from being centered around a work life to being centered around religion, travel, clubs or organizations, or volunteer activities.

Not only does aging affect our bodies, our minds, and our relationships, it also affects our nutritional status. This publication highlights nutrition and wellness practices to help you maintain a healthy, productive lifestyle—lifelong goals for everyone.

Remember that most age-related changes are gradual, and considerable variation exists in how older adults are affected by them. As a rule, we are well equipped to handle our age-related changes.

Aging Facts

* The young-old are between the ages of 65 and 80.
* The oldest-old are aged 81 and older.
* In 2030, the U.S. Census Bureau projects that the number of older adults will exceed the number of children.
* In 2030, 21% of the population will be people 65 and older.

Eat the Food Guide Pyramid Way

The Food Guide Pyramid is a general guideline to help children, youth, and adults eat a well-balanced diet. It is based on the Dietary Guidelines for Americans. Everyone should eat at least the minimum servings from each group of the Food Guide Pyramid. This gives you a variety of daily vitamins, minerals, protein, and fiber. Also, research shows that a variety of foods have other naturally occurring ingredients, such as antioxidants and phytochemicals. These ingredients may decrease the risk of cancer and heart disease.

As you age, your lifestyle may become less active; you may sit more and perform less vigorous exercises or physical labor. In addition, your body’s metabolism may be less efficient or slower. These lifestyle and metabolism changes may cause weight gain and less efficient absorption of nutrients. Select more nutrient-dense foods with lower amounts of fat and sugar (empty calories). If you are having problems losing weight, limit your fat or sugar intake. Eat a variety of foods that are good sources of protein, vitamins, minerals, and fiber.

The New Food Guide Pyramid

Recently, researchers from Tufts University developed a Food Guide Pyramid to represent more accurately the calorie and special nutrient needs for healthy persons over the age of 70. The new Modified Food Guide Pyramid for 70+ Adults includes the following changes:

* Eat at least the minimum number of servings for each food group in the Food Guide Pyramid. Eat a variety of foods that are good sources of protein, vitamins, minerals, and fiber. It is important to eat nutrient dense foods with calories. Eating fewer foods or calories may be due to poor appetite, less activity, or medical conditions, which may result in weight loss.

* Eat at least three servings of calcium-rich foods. Calcium and vitamin D are important to maintaining bone health.
* Drink eight cups of water as the base of the 70+ Pyramid. This is needed because of a higher intake of medications and to prevent dehydration and constipation.
* Eat fiber-rich foods from grains, fruits, vegetables, dried beans, and nuts.
* Eat fortified foods with vitamin B12, calcium, and vitamin D. Consult a doctor or dietitian if you need a dietary supplement.

Eat a Diet Rich in Fiber

Fiber (F) or roughage is important to having a healthy digestive system and proper bowel function. Constipation is a problem for many aging adults. Choose a variety of high-fiber foods—vegetables, fruits, beans, nuts, and whole-grain products—drink plenty of water and be physically active to stay regular. Eat at least one high fiber food (pears, dried beans and peas, corn, dates, 100% bran cereals, or potatoes with skins) daily to help you get 20 to 35 grams of fiber each day.

Drink Enough Fluids

Water or other liquids are needed to avoid and prevent constipation and dehydration. Drink six to eight eight-ounce glasses of fluid every day—water or other liquids (100% juice, soy, almond or rice milk, beverages, or soup). Limit your intake of caffeinated drinks (coffee, tea, and soda). If you are taking medications, you need more water. Take water breaks throughout the day, or in the morning, fill up a glass to remind you to drink water.

Eat Calcium-Rich Foods

Calcium and vitamin D are essential to maintaining strong bones and teeth. After age 50, your body needs more calcium, or at least 1,200 milligrams, to prevent a disease called osteoporosis. As you age, your bones lose minerals and they may get thinner. Protect your bones by choosing calcium-rich foods, such as milk, cheese, yogurt, greens, broccoli, sardines, canned salmon with bones, dried beans and peas, tofu, and calcium-fortified foods. If you have problems digesting milk:

* Eat green leafy vegetables,
* Eat yogurt or cheese, where the lactose has been broken down,
* Eliminate cow’s milk and substitute for healthier soy, almond, or rice milk,
* Eat other calcium-rich foods that are not milk-based.

Vitamin D helps the absorption of calcium. It is found in soy, almond, and rice milk, as well as fortified cereals. Your body can make its own vitamin D when your skin is exposed to the sunshine. Try to take a walk or sit in the sun for 20 to 30 minutes several times a week. This is especially important in the winter when there is less sunlight. Remember to use sunscreen when you are in the sun.

Eat Protein-Rich Foods

Body proteins are constantly being made and used during your lifetime to maintain cell and organ functions. Adequate protein intake and protein reserves are important for older adults, especially during periods of emotional and physical stress. Protein helps prevent muscle loss. Eat protein-rich foods such as meats, fish, dried beans and peas, or tofu. These foods are also good sources of iron and zinc.

As you age, vitamin B-12 levels in the blood usually decrease. Vitamin B-12 is needed to make red blood cells and maintain the central nervous system. Animal foods are good sources.

Eat a Plant-Based Diet

Research reveals that a variety of nutrient-dense fruits, vegetables, and whole grain foods may protect cells against free radicals (unstable compounds). They may also help protect you against the adverse effects of everyday cancer-causing agents, such as pollution, dietary factors, tobacco smoke, and viruses.

Phytochemicals are chemicals or ingredients found naturally in all plant foods. Some phytochemicals help protect a healthy, normal cell from turning into a cancerous cell. In addition, phytochemicals may slow the growth of tumor cells.

Eat colorful meals and snacks by choosing lots of fruits, vegetables, dried beans, nuts, and whole grain foods. This is the easiest way to get all of these important nutrients.

* Vitamins A, C, E, D, niacin, riboflavin, thiamin, folate, B-6 and B-12
* Minerals such as calcium, iron, and zinc
* Fiber, both soluble and insoluble
* Proteins, carbohydrates, and fats

Antioxidants

Antioxidants are compounds found in foods such as vitamins A, C, and E. They protect us from cell damage and may reduce the risk of cancer and heart disease, and may slow the aging process.

Fruits and vegetables supply antioxidants other than those you can get from pills, say researchers at the USDA’s Jean Mayer Human Nutrition Research Center on Aging at Tufts University in Boston.

Ron Prior and coworkers fed 36 men and women aged 20 to 40 or 60 to 80 a diet containing ten servings of fruits and vegetables a day. They then measured the “antioxidant capacity” of the participants’ blood samples by seeing how well the blood deactivated damaging oxidized free radicals in a test tube.

After two weeks, the antioxidant capacity of the participants’ blood rose in both groups, though more consistently in the older people.

“Based on this and other studies, it appears that compounds other than vitamins C and E and carotenoids contribute a major portion of the increase in antioxidant capacity,” said Prior. Among the foods with the highest antioxidant capacity were oranges, cauliflower, and peas.

Should I Take Supplements?

We see ads every day in the media for dietary supplements that promise to prevent aging changes or improve physical, mental, and nutritional health. Although we know that vitamins, minerals, antioxidants, and possibly some herbs are beneficial to health, it is important that we don’t use supplements in place of food or in extremely high amounts. Some herbal remedies or high potency vitamin or mineral supplements can interfere with the action of certain prescription and over-the-counter medications. Be sure to check with your doctor before starting any dietary supplements.

Vitamin B-12 can be a problem nutrient for older people. In nature, vitamin B-12 is found only in animal foods. Acid normally found in the stomach releases the vitamin B-12 from the animal proteins, where it was found. Unfortunately, the amount of stomach acid decreases as we age, resulting in lower body levels of vitamin B-12. Vitamin B-12 found in fortified foods can be absorbed by older people despite lower stomach acid. Regular use of a breakfast cereal fortified with vitamin B-12 helps supply this vitamin.

Some older people have poor appetites resulting from their health conditions, lack of exercise, or as a side effect of certain medications. Older people with low food intake who rely on a nutritional supplement to help provide needed amounts of protein, vitamins, and minerals should seek the advice of a health professional when selecting a supplement. Well-meaning family or friends do not have the educational background to help you avoid dangerous drug interactions. Store clerks may be more interested in selling products than providing reliable information. Liquid nutritional supplements are very expensive and don’t always contain other important dietary components such as phytochemicals or fiber. Your doctor, if trained in nutrition, or a nutritionist is the best source of information.

Osteoporosis

Osteoporosis is an age-related bone disorder characterized by thinning of the bones where bones become fragile and prone to fractures. This chronic, progressive disease affects more than 28 million Americans, and about 80% are women.

Osteoporosis offers unique challenges to older adults. Most people in the early stages of osteoporosis experience few or no signs or symptoms. If the disease progresses and multiple fractures occur, many people have pain, particularly after standing for a long time, bending and reaching, and riding in a car. This often makes performing daily activities difficult. Unable to do them alone, older adults with osteoporosis often rely on their spouses or adult children for help. Older women and men with osteoporosis may experience stress and depression. These problems often result in withdrawal from social relationships and activities and increased feelings of isolation and loneliness.

Successful strategies used by older people to cope with osteoporosis include the following.

Physical Strategies: do weight-bearing exercises; eat a balanced diet rich in calcium and vitamin D; limit lifting, pushing, and pulling; rest and take breaks during the day; say “no” to activities that cause pain.

Psychological Strategies: seek information; read or watch television as a distraction; try biofeedback or relaxation techniques; talk to a friend or family member; join a support group.

Medical Strategies: ask your doctor about approved medication; see a doctor of chiropractic or physical therapist; talk to a nutritionist.

Social Strategies: keep in contact with and accept help from family members and friends; modify social and recreational activities; develop new interests and skills.
