Cold-pressed juices and smoothies can add fruits and vegetables to your diet, but they can also pack in calories.

According to food industry statistics, there's a healthy trend afoot. People are shifting from sugary sodas and processed bottled juice drinks to beverages like cold-pressed juices and smoothies. Sales of juice extractors and blenders lead the small-appliance market, and juice bars continue to spring up on city streets, in shopping malls, and even in supermarkets.

There are a couple of reasons people are taking to these beverages, says Kathy McManus, director of the Department of Nutrition at Harvard-affiliated Brigham and Women's Hospital. "They think they are doing something healthy, and the beverages can be time savers. It can be faster to grab a smoothie in the morning instead of sitting down to breakfast."

Forgoing drugs that slow bone loss to avoid rare side effects can be the wrong decision for your hips and spine.

A front-page article in the June 1, 2016, edition of The New York Times carried this headline: "Fearing drugs' rare side effects, millions take their chances with osteoporosis." The article described a situation all too familiar to doctors. Women are declining prescriptions of bisphosphonates—drugs that slow the rate at which the body breaks down bone—or discontinuing the medications far earlier than recommended. In fact, according to a 2015 report in the Journal of Bone and Mineral Research, the rate of bisphosphonate use fell by half between 2008 and 2012. That article documented a wave of media coverage of scientific studies that reported two rare side effects—osteonecrosis (bone death) of the jaw and atypical fractures near the top of the femur (thigh-bone)—and suggested that the reports had kindled fears that had led women to abandon bisphosphonates.

"The perception of risk is so much greater than the actual risk," says Dr. Meryl LeBoff, director of the skeletal health and osteoporosis center at Harvard-affiliated Brigham and Women's Hospital. Compared with many other common diseases, we are fortunate that we have good therapies to reduce the risk of osteoporotic fractures by 70% at the spine and 40 to 50% at the hip. She points to statistics referenced in the New York Times article: for every 100,000 women taking a bisphosphonate, fewer than three will have osteonecrosis of the jaw and one will have an atypical femur fracture, but 2,000 will have avoided an osteoporotic fracture.

Both wearing a bite counter and eating from a small plate were linked to lower calorie consumption. 

Long-term doses of certain medications may rob you of calcium, folic acid, and crucial B vitamins.

Short-term medication use will not lead to nutrient deficiency. But long-term use may interfere with your body's ability to absorb nutrients or produce them.

Medications are well known for causing side effects such as nausea or drowsiness. These are the kinds of side effects you notice and can do something about. But sometimes a lesser known side effect happens without giving you any warning: nutrient deficiency.

Most food manufacturers have until July 2018 to implement the changes.

Nutrition Facts labels on food packages made headlines when the FDA ordered a makeover for them in May of this year. But will the big to-do translate to big changes in the way you make food choices? "I'm hopeful it will," says Kathy McManus, director of the Department of Nutrition at Harvard-affiliated Brigham and Women's Hospital. "It will be great if the labels can get people to look at the numbers and think more about their health."

Boosting intake of whole grains, such as wheat or oats, may reduce the risk of an early death.

The FDA is warning that over-the-counter antacids with aspirin in them can cause stomach bleeding in rare cases. 

A daily aspirin may help defend against heart disease, but it should still be used with caution.

Aspirin tablets have been a staple of home medicine cabinets and first-aid kits for nearly 100 years. Long before that, people chewed willow tree bark, which contains aspirin-like compounds, to treat a variety of ailments. On top of being an excellent painkiller and fever reducer at its standard dosage, aspirin dramatically reduces the risks for a second heart attack and certain types of stroke when taken daily at a low (81-mg) dose. Research also suggests that aspirin might help limit the growth of colorectal cancer and possibly inhibit other cancers as well, but more research in this area is needed.

These benefits, coupled with the fact that aspirin is both cheap and relatively safe, have led the U.S. Preventive Services Task Force (USPSTF) to recommend that even some healthy people take a daily aspirin to ward off future disease. But figuring out exactly who is likely to benefit most from this therapy is a more complex calculation, says Dr. Michael Gaziano, a professor of medicine at Harvard Medical School and cardiologist at Brigham and Women's Hospital.

People who eat at least four servings of whole-grain foods per day appear to have a 23% lower risk of dying of cardiovascular disease compared with people who eat little or no whole grains.

Medication can be an unpredictable and costly expense. Whether it is short-term treatment or multiple drugs you take indefinitely, prescriptions can have a serious impact on your wallet.

Nowadays there are many generic versions of brand-name drugs that are often significantly less expensive. There are generic drugs to treat most common ailments, such as pain, high cholesterol, high blood pressure, diabetes, asthma, and depression.
