Between 1959 and 2014, average life expectancy in the United States rose astoundingly by nearly a decade. Then it began declining. A recent report examining this situation raises tough questions about that unexpected change.

One of the first cultivated grains, wheat is now ubiquitous in the average American diet. In the United States, about 75% of all grain products (such as bread, pasta, tortillas, cakes, and pastries) are made with wheat. Unfortunately, most of these commonly consumed foods are made with white flour: wheat kernels that have been stripped of their outer bran and inner germ layers and milled into a fine powder. White flour is fortified with some of the vitamins and minerals removed during this refining process. But most of the fiber and other healthful plant-based chemicals found in intact whole grains are missing.

Eating more whole grains is linked to a lower risk of heart disease and cancer, which is why the federal dietary guidelines say to "make half your grains whole." But most people aren't even close to that goal. According to the CDC, whole grains account for only about 16% of the total grain-based food adults eat on any given day.

A recent study suggested that eating red or processed meats won't necessarily harm your health. What is the truth?

The news headlines were everywhere: "It's Okay to Eat Red Meat." The source for this statement was a study published online Oct. 1, 2019, in Annals of Internal Medicine.

An international team of researchers conducted five systematic reviews that looked at the effects of red meat and processed meat on multiple health issues, such as heart disease, cancer, diabetes, and premature death.

Q. I started having side effects from a prescribed drug. I stopped taking it, but the side effects are still there. How long does it take for a drug to be out of your system?

A. Most drugs will be out of your system quite quickly, but the symptoms of side effects may remain for some time. It depends on the medication and what kind of side effect has developed. The majority of prescription drugs are cleared out of your body rapidly by your kidneys and liver. Trace levels of a medicine may remain in the system while the liver and kidneys finish their filtering job. But these levels are often too low to have any noticeable effect. Patients with kidney or liver disease, however, can continue to have elevated blood levels of a drug even after stopping it.

Q. I'm 80 and no longer do colon cancer screening. However, I recently noticed some bleeding from my rectum. Does that change my need for a colonoscopy?

A. Screening for a disease means the person has no symptoms. Since you now have rectal bleeding, a colonoscopy would be considered not a screening test, but a diagnostic test. Whether you have it now or wait to see if more bleeding occurs depends upon many factors. The most important question is whether anything found on the colonoscopy will lead to treatment that improves your quality of life.

Here's what to do when your mind tends to wander.

Everyone's attention can drift at times, like when you lose your concentration for a moment while doing routine tasks.

Many people shrug off these lapses in focus as "senior moments," but they might be related to a vulnerable brain process called executive function.

Chronic stress is associated with an increased risk of heart disease, heart attacks, and strokes. These strategies can help you manage it.

People often complain about stress, but it's actually a natural reaction with an essential purpose.

When the body senses danger, it starts its fight-or-flight response. Your nervous system releases hormones like adrenaline and cortisol, which jolt the body into a protective mode. Your heart pounds faster, muscles tighten, blood pressure rises, breathing quickens, and your senses sharpen.

If you have put off cataract surgery, consider this: the procedure could make you a safer driver, according to research presented in October 2019 at the Annual Meeting of the American Academy of Ophthalmology.

Cataracts, in which the lenses of the eyes become cloudy, are a normal part of aging. Vision changes due to cataracts occur slowly, so people often don't realize they have trouble seeing at night and struggle with depth perception. While cataract surgery is low-risk and effective, many people avoid it because they feel their cataracts don't interfere with their quality of life.

People with high blood pressure may benefit from taking their antihypertension medication at bedtime instead of the morning, according to a study published online Oct. 22, 2019, by the European Heart Journal.

The researchers looked at about 19,000 people (most of them men) who took blood pressure medication. Participants took their daily dose either upon waking or before going to bed. Everyone's blood pressure was checked over 48 hours once a year for six years.

Q. Every winter I experience mood changes. How do I know if it's seasonal affective disorder?

A. Seasonal affective disorder (SAD) is a type of depression that typically affects individuals during the winter months. Some experts believe it's triggered by a reduction in natural light, which starts in the fall and continues until the spring. Tracking your mood changes can help your doctor determine if you have the condition. People formally diagnosed with SAD experience episodes of major depression that occur in the fall and winter for at least two years. During these episodes, people may feel hopeless or worthless, have sleep problems, or experience changes in appetite or weight. They may also be irritable or anxious and lose interest in favorite activities.
