Never before has so much good nutritional advice been available from so many sources -- from nutrition facts panels on food labels to books by highly respected experts.
But there’s plenty of misinformation out there, too. For seniors looking for reliable information about healthy aging and nutrition, separating facts from fiction can be tricky. Most standard dietary advice is geared to middle-aged Americans, not seniors. Only recently have researchers looked closely at the specific nutritional needs in older adults. Their findings have toppled more than a few myths about nutrition and aging.
Is there such a thing as a longevity diet? Increasingly, studies suggest the answer is yes.
Around the world, certain groups of people enjoy exceptionally long lives. Consider the lucky people of Okinawa. These Pacific Islanders have an average life expectancy of more than 81 years, compared to 78 in the United States and a worldwide average of just 67. Closer to home, members of the Seventh Day Adventists, who typically eat vegetarian diets, outlive their neighbors by four to seven years on average...
Myth: Once you reach your 60s, metabolism slows down and you need fewer nutrients.
Fact: While it’s true that older people typically require fewer calories than young adults, they actually need more of certain nutrients. The reason: As we age, our bodies are less efficient at making or absorbing some vitamins and minerals. The skin’s ability to generate vitamin D from sunlight declines. The body’s ability to absorb B12 also decreases.
“With age, the requirements for calcium, vitamin D, and B12 may all increase,” says Alice H. Lichtenstein, DSc, senior scientist and director of the cardiovascular nutrition laboratory at the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University.
Because seniors typically need fewer calories yet more of some key nutrients, they must take special care to eat nutrient-rich foods.
Myth: Older adults don’t need to worry about becoming overweight or obese.
Fact: Excess weight is a growing problem even among older Americans, says Lichtenstein. The culprit for people of all ages is simple: Consuming more calories than needed. Those extra calories are then stored as body fat. Excess body fat increases the risks of heart disease and type 2 diabetes.
Myth: If you don’t have a weight problem, you can eat whatever you like.
Fact: “Being overweight certainly increases the risk of chronic illnesses,” says Nancy Wellman, RD, past president of the American Dietetic Association. “But even if you’re slim, a poor diet can raise your risks of developing any of these chronic diseases.” Diets overloaded with saturated fat are linked to cardiovascular problems, for example. The bottom line: Following healthy nutrition advice is important whether you’re thin or fat.
