Healthy eating for older adults Archive

Postprandial hypotension, low blood pressure that occurs after eating, can cause dizziness, chest pain, nausea, or other issues, particularly in the elderly.

Trans fats and saturated fats can raise LDL cholesterol levels. A diet rich in unsaturated fats, whole grains, and fruits and vegetables can lower them.

The growing field of health and wellness coaching uses motivational techniques and positive psychology to offer people individualized support as they work to achieve their health goals.

Some drugs that contain ranitidine (best known as Zantac) have been found by the FDA to have unacceptable amounts of N-nitrosodimethylamine (NDMA), a possible cancer-causing chemical (which also triggered recalls of certain lots of the blood pressure drugs called angiotensin-receptor blockers).

On April 1, 2020, the FDA requested that all forms of ranitidine (Zantac, generic versions), including prescription and over-the-counter products, be removed from the market. They may contain unacceptable levels of a potential cancer-causing substance known as NDMA, or N-Nitrosodimethylamine. In some samples tested by the FDA, the impurity appears to increase over time, especially when stored at higher temperatures. So far, tests of other acid blockers do not show this potential increased cancer risk. 

Cannabis use among older adults has been steadily increasing, due to lessening stigma and increased interest in using medical marijuana. But there are specific concerns for older people, so anyone considering this option should have a conversation with their doctor weighing the benefits and risks.

How much dairy should you consume each day? And are some dairy products or milk alternatives better for heart health than others?

These days, the supermarket dairy aisle can be tricky to navigate. Along with the nonfat, 2%, and full-fat cow's milk lining the refrigerated shelves, you'll often find a dizzying array of plant-based milk alternatives made from different nuts, beans, and grains. Even the yogurt and cheese sections now feature nondairy products, such as coconut yogurt and cashew cheese.

The expanded choices reflect the growing trend toward plant-based diets, which people embrace for a range of reasons. Some people minimize or avoid meat, dairy, and other animal-based foods because of religious reasons or concerns about environmental sustainability or animal welfare. People who are focused mainly on a heart-healthy diet know to steer clear of red and processed meat. But when it comes to dairy products, the story isn't quite as straightforward.

You've heard (in these pages, and others) that a healthy lifestyle can stave off chronic disease. But just how many extra disease-free years might you get from that healthy lifestyle? A lot, suggests an observational Harvard-led study published online Jan. 8, 2020, by The BMJ. Researchers evaluated more than 30 years' worth of health data from 111,000 people who were free of cancer, diabetes, and cardiovascular disease at age 50. Compared with those who didn't follow any healthy lifestyle habits, those who followed four or five healthy habits had an additional decade of disease-free living. The elements of a healthy lifestyle will come as no surprise: don't smoke, limit alcohol intake, eat a healthy diet, maintain a healthy weight, and exercise at least 30 minutes per day. The surprise is just how many additional disease-free years a healthy lifestyle can give you.

Getting the right amount is really about just listening to your body.

Many experts these days are advising women to drink lots of water to stay in good health, and women seem to be listening. It's common to see people toting around voluminous bottles of water and swigging from them all day long. And there's no question that water is necessary for optimal health: it keeps your urinary tract healthy, keeps food moving along your digestive tract, helps regulate your blood pressure and body temperature, and works to cushion and protect joints, organs, and other tissues.

One recent study suggested that not drinking enough water could also affect women's cognition. The study, published online in November 2019 by the European Journal of Nutrition, found that women with lower scores on a test that measured how hydrated they were (called serum osmolarity) also scored lower on cognitive tests that measured recall, attention, mental processing speed, and verbal fluency.

In the old days, doctors would make house calls; that rarely happens today. However, a new kind of "house call" is in the works: in many cities it's now possible to receive hospital care at home for certain conditions. Such "home hospital care" programs are gaining in popularity. A randomized controlled Harvard study published online Dec. 17, 2019, by Annals of Internal Medicine suggests that the home hospital model of care is less expensive and leads to fewer readmissions than in-hospital care.

Researchers studied about 90 people who'd been diagnosed in the emergency room with infections or flares of heart failure or breathing problems. Half of the people were admitted to hospitals, and the other half were enrolled in home hospital care. The home hospital care group received visits from doctors and nurses, intravenous medications, and video monitoring. People in the home group had 38% lower hospital costs than those in the hospital group, they were more active during care, and they were readmitted to the hospital within 30 days after their care less frequently (7% vs. 23%) than those in the hospital group. Home hospital care is not appropriate for everyone. "If someone is too sick or is in need of advanced procedures, their care may be better delivered in a traditional hospital," says Dr. David M. Levine, the study's lead author and an internal medicine specialist with Harvard-affiliated Brigham and Women's Hospital. However, if you have an illness that needs constant monitoring and treatment for several days — in other words, it can't be done in a doctor's office — yet it also doesn't require advanced procedures or constant and intensive nursing care, the home hospital care model may make sense. "If the home hospital model were offered to a member of my family, I'd encourage them to do it," says Dr. Levine.
