From fast-food restaurants and delis exploding with high-calorie sandwiches to salad bars stocked with high-fat and high-sugar add-ons, lunchtime can be a minefield of temptation for those trying to eat a healthy and balanced diet.

But a healthful — and enjoyable — lunch can be done. These simple tips can help.

Declining testosterone is a normal part of aging, but is replacement therapy right for you? Here is what you need to know.

Testosterone replacement therapy (TRT) has surged in popularity over the past decade. Millions of older men have turned to TRT to restore hormone levels in hopes of refueling energy and reigniting their sex drive.

Yet TRT remains controversial because of its uncertain benefits and potential health risks. Safety concerns were raised years ago when studies showed a possible association between TRT and an increased risk of cardiovascular disease.

Proton-pump inhibitors are among the most-prescribed medications, but is long-term use safe?

Proton-pump inhibitors (PPIs), which are used to treat a variety of gastrointestinal problems, are among the most popular drugs in the United States. In fact, the FDA estimates about one in 14 Americans has used a PPI.

Increasing daily water intake by one, two, or three cups daily can help reduce total calorie intake and lower a person’s intake of saturated fat, sugar, sodium, and cholesterol.

Eating 10 servings of green leafy vegetables per week, or about 1.5 cups per day, may lower a person’s risk for primary open-angle glaucoma by 20% to 30%. These foods are rich in nitrate, which can help reduce eye pressure and improve blood flow to the optic nerve.

Each of your medications may be affecting how the others work, leading to harmful side effects and complications.

Each additional medication you take increases the risk of drug interactions.

Are you taking more than one drug? Are you taking a few different types of medications? Are you seeing several different doctors? If so, you may be at increased risk for drug interactions, which occur when a drug, a supplement, or even a food affects the way your body processes a medication. Such interactions can make a drug more powerful—so that a standard dose becomes an overdose—or can render it less potent or altogether ineffective.

Inflammation is an important link between obesity, elevated blood sugar, and type 2 diabetes.

We've known for a long time that being overweight is a major risk factor for developing type 2 diabetes. But only in the last 20 years have researchers determined that metabolism and immune responses are linked and that chronic inflammation plays an important role in the development of obesity, diabetes, and related metabolic diseases. "Inflammation is not only associated with obesity, diabetes, and cardiovascular disease, but also precedes and predicts these conditions," says Dr. Allison Goldfine, head of the Clinical Research section at Harvard-affiliated Joslin Diabetes Center.

Research We’re Watching

In the 2015–2020 Dietary Guidelines for Americans, the emphasis shifted from healthy foods to healthy eating plans. Scientists are also focusing on the role of one's entire diet in preventing osteoporosis.

A team of German researchers analyzed data from more than 90,000 women enrolled in the Women's Health Initiative (WHI), who were ages 50 to 79 when they entered the study.

They follow their own advice to enjoy lots of vegetables, legumes, lean protein, and a fruit-based dessert.

Following a healthy diet is a proven and powerful way to lower your risk of heart disease. But do you ever wonder if doc-tors actually practice what they preach, especially with regard to their eating habits? While we obviously can't speak for all of them, four Harvard physicians with diverse ethnic backgrounds agreed to share examples of their favorite heart-healthy dinner menus.

About one in six strokes can be traced to atrial fibrillation. Doctors now have newer and better options to lessen this risk.

Close to one in 10 people ages 65 or older have atrial fibrillation (afib), the most common heart rhythm disorder. During a bout of afib, the usually rhythmic contractions of the heart's upper chambers (the atria) are replaced by an ineffectual quiver. While the symptoms, which include a racing heartbeat, dizziness, and shortness of breath, are troublesome for some people, the real threat lies in the increased risk of stroke that accompanies the condition.

When the heart takes on the afib rhythm, blood does not completely move out of the atria. Instead, it tends to pool and clot in a pouchlike extension in the upper left quadrant of the heart, called the left atrial appendage. If these clots break loose, they may travel to the brain and cause a blockage. This is known as an ischemic stroke.
