Meeting fiber goals improves overall nutrition and helps with regularity, even without dramatic dietary changes.

Physical therapy is helpful for wear-and-tear knee osteoarthritis, especially if you start doing it early. But injecting a painful knee with an anti-inflammatory steroid medication before starting physical therapy offers no additional benefit, according to a clinical trial in JAMA Internal Medicine.

Studies have shown that physical therapy modestly reduces pain and improves daily functioning in people with knee osteoarthritis. That could mean being able to walk farther with less pain or to continue leisure activities such as gardening. Before you start physical therapy, your doctor may offer to inject the knee with a cocktail of anti-inflammatory steroid medication and an anesthetic. Hypothetically, this could make it easier for you to stick with exercise and therefore lead to better results.

Foods such as kale, cantaloupe, and quinoa can boost the amount of nutrients you consume without increasing calories.

Getting enough nutrients through diet is challenging as we age. Our bodies don't absorb nutrients as well as they once did, yet we tend to need fewer calories and eat less. So it's important to make the most out of the foods we do eat. One way is by choosing more nutrient-dense foods, which provide more nutrition bang for the calorie buck. "They contain an abundance of nutrients and other healthful substances—vitamins and minerals, fiber, lean protein, and unsaturated fats—but are not excessive in calories. This is compared with foods of low nutrient density that are high in calories," says Liz Moore, a registered dietitian at Harvard-affiliated Beth Israel Deaconess Medical Center.

Fatty plaque in the arteries that feed the kidneys poses a danger to the heart and brain.

Some research has suggested that older people who take blood pressure medications may be prone to falls, perhaps because the drugs make them dizzy or lightheaded when they stand up. But a new study in the May 2015 Hypertension found no increased risk of falls in people taking blood pressure drugs.

For the study, nearly 600 people with chronic high blood pressure reported their falls to researchers via mail-in postcards and phone calls. Almost half of the participants, whose average age was 78, reported one or more falls during the yearlong study. Neither standard nor high doses of blood pressure drugs were linked to falls. In fact, people who took two commonly prescribed types of blood pressure medications—ACE inhibitors and calcium-channel blockers—had a lower rate of falling compared with people not taking those drugs. Given the known benefits of treating high blood pressure in older people, the authors say, withholding blood pressure medication for fear of causing a fall may not make sense.

Serious health problems are uncommon after drugs or surgery to treat chronic heartburn, according to a recent study in Alimentary Pharmacology and Therapeutics. Many men take acid-reducing drugs called proton-pump inhibitors (PPIs), such as omeprazole (Prilosec, others) and lansoprazole (Prevacid), for chronic heartburn. One alternative is a surgical procedure to tighten the entrance to the stomach and prevent acidic stomach contents from backing up into the esophagus.

The new study drew on findings from two different clinical trials that tracked the health of people treated with either drugs or surgery. One trial involved about 300 people who were followed for up to 12 years; the other involved about 500 people who were followed for five years.

It appears that cognitive behavior therapy may help people with chronic insomnia and no underlying medical problems fall asleep faster.
