One in eight Americans is 65 years of age or older. This number is growing and will continue to do so with the aging of the baby boomers. The oldest old, people who are at least 85 years of age, is the fastest-growing segment of America's senior population.
What You Will Learn
You will learn the importance of good nutrition in helping the elderly to:
The U.S. Department of Agriculture MyPlate is a tool that guides Americans in selecting which foods to eat and how much to eat each day to be healthy. MyPlate contains five food groups: fruits, vegetables, grains, protein foods and dairy. Each day, people of all ages should eat a variety of foods from each food group. Foods containing solid fats and added sugars, such as cookies, pies, cakes and sodas should be limited. For more information on healthful eating and physical activity, go to www.choosemyplate.gov. Look for the SuperTracker to create a personalized meal plan. You can also set goals and track your food intake and physical activity
Physical and body function changes take place during aging and can result in changes in nutrient needs. These changes can contribute to decreased food intake, unintentional weight loss and malnutrition. Not everyone experiences all these changes.
Here are some changes that may occur:
Because Americans are living longer, it is important for us all to plan well for a long life. It is never too early nor late to begin. Aging well depends on several factors, some of which include the following: personal health and well-being, lifestyle issues (housing, leisure activities, lifelong learning) and finances. It is important to remember and understand that today's choices do have consequences in later life.
In this lesson, we will focus on only one factor of aging well: health.
Research has shown that nutritional status influences the progress of many diseases and that having good nutritional status can help to reduce the length of hospital stays.
Being well-nourished is important for several reasons:
The United States Department of Agriculture (USDA) Continuing Survey of Food Intakes by Individuals (CSFII) provides up-to-date information on food intake by Americans. This survey indicated that adults have low intakes of fiber, magnesium and zinc. These results could be improved by eating more whole grains, fruits, dark green vegetables and legumes. Consuming low-fat dairy products is important in that it can help to boost calcium levels. The study also found more adults to be overweight than before. Adults' diets could benefit overall by simply decreasing intakes of foods and beverages that are high in fats and sugars. Low activity levels were also shown to contribute to the large numbers of adults who were overweight. For better health, adults should become more active, incorporating activities into their everyday living.
Nutrients to be concerned about:
Vitamin A supplements: The need for supplements containing vitamin A decrease with age, making toxicity from supplements more common as one ages. Adequate vitamin A can be obtained in the diet alone through several different food sources. Breakfast cereals, juices, dairy products and other foods are fortified with vitamin A. Also, dark green and yellow, orange and red vegetables and fruits contain beta carotene and other vitamin A precursors, which the body can use to form vitamin A.
Protein: Protein needs increase with age. Low-protein and calorie intake can make a person more likely to get sick and can also make it harder to recover from an illness. Foods that are excellent sources of protein include meat, poultry, fish and eggs. Other sources of protein include the following foods: dairy foods, such as milk, yogurt and cheese; soy products, such as tofu and soy milk; beans and peas; nuts and seeds.
Vitamin D (the sunshine vitamin): Vitamin D is needed for the absorption of calcium. Calcium and vitamin D work together to build strong teeth and bones. Luckily, most individuals are able to receive enough vitamin D from sunshine alone. This is why vitamin D is known as the sunshine vitamin. Your body produces vitamin D when your skin is exposed to the sun for 10-15 minutes every day. Some individuals have been shown to have much lower levels of vitamin D, including African-Americans and other individuals with dark skin. This is believed to be due to less formation of the vitamin from the action of sunlight on the skin. The elderly, as well as adults and children are at risk of vitamin D deficiency. Some good dietary sources of vitamin D include fatty fish, such as salmon, tuna and mackerel, mushrooms, beef liver, egg yolks and cheese. Milk, yogurt, orange juice, breakfast cereals and other foods are fortified with vitamin D. Cod liver oil is rich in vitamin D. Some individuals prefer getting their daily intakes of vitamin D from a multivitamin; however, levels found in most multivitamins are too low.
Vitamin B-12, vitamin B-6 and folate: These are believed to prevent some of the decline in cognitive function that is associated with aging. Deficiencies of these nutrients, along with low intakes of vitamin C and riboflavin, may result in poor memory. Folate, along with these other two B vitamins, is believed to play some role in fighting heart disease and some types of cancer. Further research is still needed in this area, however. Folic acid has recently been fortified in several foods, making it much easier now than in past years to receive adequate amounts from the diet. Good dietary sources of folic acid include enriched breads, flour, cornmeal, pastas, rice and other grain products.
Cholesterol: Cholesterol is a waxy substance. There are two types of cholesterol: dietary and endogenous. Dietary cholesterol comes from animal foods we eat, such as meat, cheese, and eggs. Endogenous cholesterol is made by the liver, which acts to link cholesterol to carrier proteins in the body called lipoproteins that let it dissolve in blood. It is then transported all through the body. Cholesterol plays some essential roles in the body, such as in the formation of cell membranes, some hormones and vitamin D. While too much cholesterol can be problematic, very low levels of cholesterol can be as well. Very low levels may be a sign of disease and of decreased mental ability.
Beta carotene (forms vitamin A), vitamin C and vitamin E: These are all antioxidants. Beta carotene is a precursor for vitamin A. But unlike vitamin A supplements, which can occur with too high of a vitamin A intake, this is not the case with beta carotene. Beta carotene is essentially safe at all levels. Adequate levels of vitamin C can be consumed from the diet. Excellent food sources of vitamin C include citrus fruits or citrus juices, berries, green and red peppers, tomatoes, broccoli and spinach. Many breakfast cereals are also fortified with vitamin C. Vitamin E is an antioxidant that destroys free radicals. Free radicals damage cells and may contribute to heart disease and cancer. Vitamin E is found in foods, such as nuts and seeds and vegetable oils. All three of these compounds can help prevent the formation of cataracts of the eye, which can help prolong eyesight.
Zinc and other nutrients are believed to help improve immune function or one's ability to fight disease.
Water is important for the body to function as it should. Dehydration is a major problem in older adults, especially in those 85 and older. There are several factors that can contribute to decreased intakes of fluid in older individuals. These can include the loss of sense of thirst, medication side effects, difficulty in getting to or in using the toilet, or fear of being unable to control one's bladder. It is important to find ways of incorporating water throughout the day as to prevent dehydration.
Ways to improve the diet of an elderly person include:
Research shows that there are advantages to both aerobic and weight-bearing exercise. Older Americans are shown to be less likely to participate in fitness activities. These activities can be important to older Americans.
Walking and weight training have been shown to improve an older person's balance and ability to walk. This makes them more independent and less likely to fall and be injured. Also, regular physical activity that is done several days each week reduces the risk of developing several illnesses.
Regular physical activity improves health by reducing risk of:
Exercise also reduces feelings of depression and anxiety, helps control weight and helps build and maintain healthy bones, muscles and joints. Exercise helps older adults become stronger and better able to move without falling.
Exercise does not have to be strenuous in order to provide health benefits. Older adults who have been inactive for a while can begin exercise programs by doing short intervals of moderate physical activity (5- to 10-minute intervals). Gradually, they can build up to the desired amount of exercise. Both muscle-strengthening and aerobic activities should be included in the exercise program. Stronger muscles can help reduce the risk of falling and can help to improve one’s ability to perform the routine tasks of daily life. Among adults aged 65 years and older, walking and gardening, along with yard work, are some of the most popular physical activities.
It is important for seniors who want to begin an exercise program to first consult their doctors before beginning the program!
There are products that make it easier for older Americans to prepare and eat food. Some of the available products are:
Easy jar opener
Utensils with thick handles
Liquid level indicator

Because Americans are living longer, it is important to plan for a long life. The keys to enjoying later life are understanding and planning for what lies ahead. It is never too early nor too late to begin.
Aging well and leading a quality life depend on personal health and well-being as well as lifestyle choices such as housing, leisure activities, volunteering, and lifelong learning. Today's choices do have consequences in later life.
To promote health, eat according to the USDA Dietary Guidelines and MyPlate, and exercise!
