Older adults who eat a healthy diet tend to live longer than those who indulge in desserts and high-fat dairy products, according to a new study in the Journal of the American Dietetic Association. With the projected doubling of our older population by 2030, what people put on their plates may be even more important.
For 10 years, researchers followed the eating habits of 2,500 healthy seniors aged 70 to 79. They found people who ate ice cream, whole milk and other high fat-dairy items had a 40% higher risk of dying during the decade of study than those who ate a healthful diet. People who ate sweets such as doughnuts, cakes, and cookies had a 37% higher risk of dying in that same 10 year study period.
The seniors were placed into one of the following 6 dietary categories depending upon what they ate: 1) Healthy foods 2) High-fat dairy products 3) Meat, fried foods and alcohol 4) Breakfast cereal 5) Refined grains and 6) Sweets and desserts. The people with the more healthful diets not only lived longer they also reported having a better quality of life, for a longer period of time than others.
“Our study and several previous studies suggest that it may be important what people eat at any age and that people can perhaps increase their quality of life and survival by following a healthy diet,” explains lead author Amy Anderson, Postdoctoral Researcher with the University of Maryland's Department of Nutrition and Food Science.
Eating healthy meant including more low-fat dairy products, fruits and vegetables, whole grains, poultry and fish in the diet as opposed to meat, fried foods, sweets, highly sugared drinks and other fatty foods. The healthy group got only 3% of their calories from high-fat dairy products such as cheese and ice cream, for example, while the high-fat dairy group got 17% of their calories from these foods. The healthier group also ate fewer sweets with only 6% of their calories coming from these treats compared to 25% by those in the desserts group.
The study noted that in the past century, the leading causes of death were from infectious diseases. Now people are dying from chronic illnesses such as heart disease and cancer, which are often tied to what we eat.
“I think this research is important, especially now with the baby boomers entering these older age groups. So if people have a higher quality of life and survival , if they're healthier, this can reduce the cost of health care and improve people's daily lives in general,” says Anderson.
How Much Should I Eat?
How much you should eat depends on how active you are. If you eat more calories than your body uses, you gain weight.
What are calories? Calories are a way to count how much energy is in food. You use the energy you get from food to do the things you need to do each day.
Just counting calories is not enough for making healthy choices. For example, a medium banana, 1 cup of flaked cereal, 2-1/2 cups of cooked spinach, 1 tablespoon of peanut butter, or 1 cup of 1% milk–all have roughly the same number of calories. But, the foods are different in many ways. Some have more of the nutrients you might need than others do. Milk gives you more calcium than a banana, and peanut butter gives you more protein than cereal. And a banana is likely to make you feel fuller than a tablespoon of peanut butter.
How many calories do people over age 50 need each day?
- who is not physically active needs about 1,600 calories
- who is somewhat active needs about 1,800 calories
- who has an active lifestyle needs about 2,000-2,200 calories
- who is not physically active needs about 2,000 calories
- who is somewhat active needs about 2,200-2,400 calories
- who has an active lifestyle needs about 2,400-2,800 calories
Here's a tip: Get at least 30 minutes of moderate physical activity on most, if not all days of the week.
How Much Is on My Plate?
How does the food on your plate compare to how much you should be eating? For example, one very large chicken breast could be more from the meat/beans group than you are supposed to eat in a whole day. Here are some general ways you can check:
3 ounces of meat, poultry, or fish = deck of cards
½ cup of fruit, rice, pasta, or ice cream = ½ baseball
1 cup of salad greens = baseball
1-1/2 ounces of cheese = 4 stacked dice
1 teaspoon of butter or margarine = 1 dice (or die)
2 tablespoons of peanut butter = ping pong ball
1 cup of flaked cereal or a baked potato = fist
Read the Label
At first, reading labels on many packaged foods may take some time. The facts there can help you make better food choices. Labels have a Nutrition Facts panel. It tells how much protein, carbohydrates, fats, sodium, key vitamins and minerals, and calories are in a serving. The panel also shows how many servings are in the package—be careful because sometimes what you think is one serving is really more.
Each can, bottle, or package label also has an ingredients list. Items are listed from largest amount to smallest.
Having Problems with Food?
Does your favorite chicken dish taste different? As you grow older, your sense of taste and sense of smell may change. Foods may seem to have lost flavor. Also, medicines can change how food tastes. They can also make you feel less hungry. Talk to your doctor about whether there is a different medicine you could use. Try extra spices or herbs on your foods to add flavor.
As you get older, you might not be able to eat all the foods you used to eat. For example, some people become lactose intolerant. They have symptoms like stomach pain, gas, or diarrhea after eating or drinking something with milk in it, like ice cream. Most can eat small amounts of such food or can try yogurt, buttermilk, or hard cheese. Lactose-free foods are available now also. Your doctor can test to see if you are lactose intolerant.
Is it harder to chew? Maybe your dentures need to fit better, or your gums are sore. If so, a dentist can help you. Until then, you might want to eat softer foods that are easier to chew.
Do I Need to Drink Water?
With age, you may lose some of your sense of thirst. Drink plenty of liquids like water, juice, milk, and soup. Don't wait until you feel thirsty. Try to drink several large glasses of water each day. Your urine should be pale yellow. If it is a bright or dark yellow, you need to drink more liquids.
Be sure to talk with your doctor if you have trouble controlling your urine. Don't stop drinking liquids. There are better ways to help bladder control problems.
What about Fibre?
Fibre is found in foods from plants—fruits, vegetables, beans, nuts, seeds, and whole grains. Eating more fibre might prevent stomach or intestine problems, like constipation. It might also help lower cholesterol, as well as blood sugar.
It is better to get fibre from food than dietary supplements. Start adding more fibre slowly. That will help avoid unwanted gas. Here are some tips for adding fibre:
- Eat cooked dry beans, peas, and lentils often.
- Leave skins on your fruit and vegetables if possible.
- Choose whole fruit over fruit juice.
- Eat whole-grain breads and cereals.
- Drink plenty of liquids to help fibre move through your intestines.
Should I Cut Back on Salt?
The usual way people get sodium is by eating salt. The body needs sodium, but too much can make blood pressure go up in some people. Most fresh food contains some sodium. Salt is added to many canned and prepared foods.
People tend to eat more salt than they need. If you are over age 50, about 2/3 of a teaspoon of table salt–1500 milligrams (mg) of sodium–is all you need each day. That includes all the sodium in your food and drink, not just the salt you add when cooking or eating. If your doctor tells you to use less salt, ask about a salt substitute. Some contain sodium. Also, don't add salt during cooking or at the table, and avoid salty snacks and processed foods. Look for the word sodium, not salt, on the Nutrition Facts panel. Choose foods labeled “low-sodium.” Often, the amount of sodium in the same kind of food can vary greatly between brands.
Here's a tip: Spices, herbs, and lemon juice can add flavor to your food, so you won't miss the salt.
What about Fat?
Fat in your diet comes from two places–the fat already found in food and the fat added when you cook. Fat gives you energy and helps your body use certain vitamins, but it is high in calories. To lower the fat in your diet:
Choose cuts of meat, fish, or poultry (with the skin removed) with less fat. 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. Choose an unsaturated or monosaturated vegetable oil (check the label) or a nonfat cooking spray. Instead of frying, broil, roast, bake, stir-fry, steam, microwave, or boil foods.
Keeping Food Safe
Older people must take extra care to keep their food safe to eat. As you get older, you are less able to fight off infections, and some foods could make you very sick. Be sure to fully cook eggs, pork, fish, shellfish, poultry, and hot dogs. Talk to your doctor or Nastaran about foods to avoid. These might include raw sprouts, some deli meats, and foods that are not pasteurized (heated to destroy disease-causing organisms), like some milk products and juices in the refrigerated section of the grocery.
Before cooking, handle raw food with care. Keep it apart from foods that are already cooked or won't be cooked, like salad, fruit, or bread. Be careful with tools–your knife, plate, or cutting board, for example. Don't cut raw meat with the same knife you will use to make a salad. Rinse raw fruits and vegetables before eating. Use hot soapy water to wash your hands, tools, and work surfaces as you cook.
As you get older, you can't depend on sniffing or tasting food to tell if it has gone bad. Try putting dates on foods in your refrigerator. Check the “use by” date on foods. If in doubt, toss it out.
Here's a tip: Make sure food gets into the refrigerator no more than 2 hours after it is cooked—whether you made it yourself or brought it home from a restaurant.
Can I Afford to Eat Right?
If your budget is limited, it might take some thought and planning to be able to pay for the foods you should eat. Here are some suggestions. First, buy only the foods you need. A shopping list will help with that. Before shopping, plan your meals, and check your supply of staples like flour and cereal. Make sure you have some canned or frozen foods in case you do not feel like cooking or cannot go out. Powdered, canned, or ultra-pasteurized milk in a shelf carton can be stored easily.
Think about how much of a food you will use. A large size may be cheaper per unit, but it is only a bargain if you use all of it. Try to share large packages of food with a friend. Frozen vegetables in bags save money because you can use small amounts and keep 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.
Here are other ways to keep your food costs down:
- Plain (generic) labels or store brands often cost less than name brands.
- Plan your meals around food that is on sale.
- Prepare more of the foods you enjoy, and quickly refrigerate the leftovers to eat in a day or two.
- Divide leftovers into small servings, label and date, and freeze to use within a few months.
Eating alone can be difficult for people of any age. It may not seem worth the effort to cook just for you. But there are ways to put the fun back into eating. Start with keeping your cupboards well stocked with nutritious foods that you enjoy. Studies show that when you eat with others, you tend to have an improved nutrient intake. So, sit down with some friends, family members or neighbours and enjoy their company while you dine. Treat yourself well; you deserve it!
Make it a pleasure
- Create a pleasant place to eat. Set a table with flowers, place mat and napkin, even candles. Listen to music.
- Sometimes moving to a different location or doing something else while eating is helpful. Take your meal out on the porch, sit near a window, go to the park for a picnic, watch TV or read a book.
- Enjoy a dinner out in a restaurant occasionally. Ask for a “doggie bag” to take leftovers home.
- Want a break from cooking? Try a no-cook meal, ready-made meals or other convenience foods.
- Consider taking Meals on Wheels a few times a week or more.
- • Share a potluck dinner with a friend, or form a regular lunch group.
- Start an eating club. The host makes soup and others bring bread, salad or fruit.
- Join a collective kitchen or share cooking with friends. Find a place where a few of you can meet to plan, shop and prepare several meals together. Take those meals home, freeze them and pull them out when you don't feel like shopping or cooking.
- Ask other seniors who are alone for ideas and suggestions, and share yours.
- Exchange recipes.
- Teach your grandchildren how to cook or bake.
- Check your local senior or community centres; many serve weekly meals.
- Beyond the nutritional benefits of eating with others, starting a supper club or joining an eating group can also help you meet new people and forge new friendships.
If you have lost your appetite for more than a day or two, talk with your doctor. Nastaran can provide food and nutrition information you can trust.
