Standing up more throughout the day may help you dodge heart disease and live longer.

Some first-generation diet pills proved risky to the heart. New drugs may have expanded the options for treating obesity.

To live longer, going for a leisurely jog just a few times a week seems to be a good strategy, according to a study in the February 2015 Journal of theAmerican College of Cardiology.

For the study, Danish researchers tracked about 1,500 healthy people for 12 years. They found that people who jogged two to three times a week at a pace of about 5 mph (defined as "light joggers") were less likely to die during the study than sedentary nonjoggers. The light joggers, who logged between one and 2.5 hours of jogging per week, also had lower death rates than moderate and strenuous joggers. However, only a small number of the vigorous exercisers died during the study, which means the findings do not provide proof that moderate or strenuous exercise is harmful. Still, the results are heartening for those who can't find the time or stamina to run faster and more often than the modest amounts achieved by the light joggers in this study. 

Q. Would you suggest I try taking a probiotic supplement for general colon health? I have a sensitive stomach and sometimes suffer from constipation.

A. Probiotics, the beneficial bacteria that live in our intestines and assist in digestion, have gained a lot of support lately. Each week, a new study appears describing health benefits or diseases associated with changes in the so-called microbiome—the diverse community of microorganisms each of us carries inside our body. Still, the benefits of adding probiotics to the intestinal tract are uncertain.

Probiotics have proved helpful in situations where the body's normal, healthy bacteria have been destroyed, such as after taking a powerful antibiotic. Small studies in people with irritable bowel syndrome have suggested that taking probiotics improves pain and diarrhea. The benefit in constipation is less certain, but it's reasonable for you to try taking a probiotic if you are interested.

Soy foods can help you build a healthy diet, but their ability to prevent heart disease and cancer remain unproven. Soy foods, from soy milk to tofu, are often touted for their health benefits. But if you add soy to your diet, be mindful about what you are pushing off the plate.

What's better for you: moderate but prolonged exercise, or a shorter but more intense workout? A recent study in Annals of Internal Medicine found that both levels of exercise will help you lose about the same amount of belly fat if you burn the same number of calories. But only high-intensity exercise helped control blood sugar levels.

In the study, 300 people with abdominal obesity walked and jogged on treadmills at a moderate or high intensity, burning equivalent numbers of calories. The 217 people who stuck through the study for the entire six months lost on average 1.75 inches from their waistlines—about 5% to 6% of body weight. It made no difference whether they huffed through the higher-intensity workout or the more moderate regimen.

Allergies can cause great misery. Luckily, there are options to help manage symptoms and continue doing the things you enjoy. The goal is to find the treatment that best suits your allergies, your lifestyle, and your wallet. Here are three of the most common ways to find relief from allergy symptoms.

Antihistamines

These medications are the mainstay for treating the sneezing, runny nose, and itchy eyes that come with allergies. Antihistamines also relieve hives and other symptoms of some food allergies.

Many people who suffer from hay fever (seasonal allergic rhinitis) are familiar with the older antihistamines such as diphenhydramine (Benadryl) and chlorpheniramine (Chlor-Trimeton). While these drugs work well, they leave many people feeling groggy, sleepy, or just "out of it." Thankfully, the newer generation of antihistamines, including cetirizine (Zyrtec), desloratadine (Clarinex), fexofenadine (Allegra), and loratadine (Claritin), are far less likely to cause drowsiness at recommended doses. Their effects are also longer lasting, so usually you need to take them only once a day instead of every four to six hours.

Many popular workouts that aim to strengthen your arms, legs, and abs give short shrift to many of the muscles that form your body's core (the group of muscles that form the sturdy central link connecting your upper and lower body). Strong core muscles are essential to improving performance in almost any sport — and are the secret to sidestepping debilitating back pain.

If you haven't been working your core muscles regularly — or if you challenge yourself with a new set of exercises — expect to feel a little soreness as you get used to your new routine.

Q. When is it time to stop driving? My kids worry that my driving skills are slipping.

A. You can drive safely if you have adequate vision, hearing, coordination, strength, and reaction time. These abilities tend to decline with age, and drivers over age 75 are involved in more fatal accidents per mile driven than younger drivers. To drive safely, you should have near-normal corrected vision, including peripheral vision. You should be able to hear a car horn or siren easily. You should be able to rotate your neck to look over your shoulder and have good sensation in your feet.
