Food for thought
Nutrition for older adults
Research from physicians at Rush University Medical Center in Chicago, Illinois, and elsewhere could one day give new meaning to the phrase “food for thought.”
Increasingly, experts are finding evidence that our diet could play a significant role in how our brains function and our risk for developing conditions such as Alzheimer’s disease. Last May, many of these experts gathered in Chicago for a conference cosponsored by Rush to discuss recent research results.
Findings concerning docosahexaenoic acid (DHA) generated considerable excitement, says Martha Clare Morris, ScD, of the Rush Institute for Healthy Aging. DHA is a type of omega-3 fatty acid found in high levels in fish. It’s important for normal brain function, but we tend to lose this type of fatty (lipid) material in our brains as we age. One study showed that omega-3 fatty acids seemed to enhance the ability of the brain’s basic nerve cells to communicate with each other. Initial research suggests that through diet you can replenish lost DHA. Morris’ work has shown that eating just one fish meal per week could lower your risk of developing Alzheimer’s disease by 60 percent, perhaps by restoring DHA.
Know it by heart
Other studies found that people with very high levels of low-density lipoprotein (LDL) cholesterol - or “bad” cholesterol - in middle age were at increased risk for developing Alzheimer’s disease 20 years later. This highlights another area that is drawing increased attention - the possible connection between heart and brain health.
“We believe that if you increase your intake of green leafy vegetables and decrease saturated fats, which you get through whole milk, animal products and fatty red meat, you’ll prevent clogged arteries and heart disease - and you might also benefit your brain,” Morris says.
This type of diet, which tends to reduce calorie intake, might also help control your weight. That could prevent a host of other health problems linked to obesity that often affect older adults, such as high blood pressure, diabetes, osteoarthritis and certain cancers.
Lab research suggests eating less can help you live longer, says Jack Olson Jr., MD, a physician at Rush who specializes in older adult care. However, it’s not advisable for everyone, especially frail older adults. And if you do eat less, it’s important that you’re still getting the nutrients your body needs. Talk to your doctor about what is best for you. n
