You’ve likely heard the saying, “You are what you eat.” Research from Brigham and Women’s Hospital takes that concept further by supporting the notion, “You become what you eat.” The study, which compared diet quality and physical function in over 50,000 women, found that those who maintained a healthy diet over the years were less likely to develop problems with physical function as they grew older.
“Physical function is crucial as you age,” Kaitlin Hagan, one of the study’s authors, said. “It includes being able to get yourself dressed, walk around the block and could impact your ability to live independently.”
Good physical function aids senior mobility, helps prevent falls and enables older adults to maintain independence in activities of daily living, such as bathing and dressing.
While the study found some foods, such as apples, oranges, pears, romaine lettuce and walnuts were strongly linked with better physical function, overall diet quality is more important than any particular wonder food. Components of a healthy diet included:
- Eating lots of fruits and vegetables
- Low intake of sugary beverages, trans fats and sodium
- Moderate alcohol use
Physical function, especially senior mobility, relies on maintaining strong bone health. The Centers for Disease Control (CDC) reports that one in three adults over age 65 falls each year, while one in five falls results in serious harm, such as broken bones or head injury. Strong bones can’t prevent a fall but may help a senior avoid getting a fracture as a result of a fall.
- Dairy products including low-fat milk, yogurt and cheese
- Orange juice or cereals fortified with calcium
- Dark leafy vegetables such as broccoli, spinach and collard greens
- Sardines or canned salmon
- Soybeans and tofu
- Almonds and hazelnuts
- White beans
Exposure to sunshine stimulates the body to produce vitamin D. For an older adult who is indoors much of the day, getting a sufficient amount may require eating foods that contain vitamin D or taking supplements. The CDC lists vitamin D deficiency, as well as lower body weakness and difficulties with walking and balance, as some potential risk factors for falls.
Vitamin D is found in eggs, fortified milk and cereals, tuna, sardines, salmon, mushrooms and beef liver. According to the NIH, people ages 51-70 should get at least 600 international units (IU) daily, while adults over age 70 should have at least 800 IUs daily. The NIH advises talking to your physician about vitamin D supplements, since taking too much could be harmful.
Even if an older adult’s eating habits were less than ideal in the past, it is worth the effort to eat healthy in the future. Doing so can help nourish and strengthen their body and help preserve the physical function that remains.
