Excess sugar in the diet can cause a whole host of health problems, both physical and mental. If you’re concerned about cutting down on sugar, you might think you’re covered if you skip the soda and pastries. But there are plenty of hidden and added sugars lurking in all kinds of foods — even those traditionally considered “healthy.” Here, we’ve given you some tips on what to watch out for.

Many pregnant women turn to zero-calorie artificially sweetened beverages to help avoid weight gain. However, these beverages may actually cause weight gain—and even alter your digestion and sense of taste. Recent research suggests that pregnant women who drink diet beverages to avoid weight gain may end up with heavier babies. So, if you’re pregnant, you may want to rethink that zero-calorie soda. After all, the old adage about “eating for two” is a reminder to eat and drink in ways that keep both you and your baby healthy.

Many people struggle with self-acceptance. A lack of self-acceptance can do more than impact your self-esteem: it can actually reduce the amount of gray matter your brain has available to work with. Fortunately, there are several different ways to increase your self-acceptance and, in the process, make real, physical changes in the way your brain works. Give it a try!

A hospital stay can be confusing and disorienting for anyone — but especially for older people, who are prone to episodes of delirium when in the hospital. Several hospital-based programs exist to help identify people at risk for delirium and prevent episodes before they happen. We’ve discussed one such successful program, plus listed tips to help you or your loved one avoid delirium during a hospital stay.

Exercise: It does so much more than burn calories

Elizabeth Pegg Frates, MD

You’ve probably heard that if you want to lose weight, it’s as simple as “eat less, exercise more.” A recent study suggests that a lot of exercise doesn’t always translate into a lot of extra calories burned. But even if you never lose a single pound with exercise, it has so many other benefits for your body and mind that it’s always worth it to be active. Give it a try today!

Hip replacement surgery is becoming increasingly common. After this type of surgery, people are required to undergo rehab to help them become stronger and steadier with their new joint. Traditionally, this has involved lots of back-and-forth to physical therapy appointments. But a new study suggests that many people may be able to do their exercises at home instead — with nearly identical results.

If you’ve looked up from your phone recently — or even if you haven’t! — you may have noticed that many children and teens are glued to their devices. While experts aren’t quite ready to call this an “addiction,” a new survey of parents and teens confirms that many of them suspect they’re too dependent on their devices. We’ve discussed the potential implications of this, plus suggested some “ground rules” for when to ignore those devices.

Phrases like “I almost died of fright” aren’t just hyperbole. The heart and brain are actually intimately connected, and emotions that are strong enough to disrupt the brain’s function can also take a measurable physical toll on the heart. Of course, this means that if you can change your brain’s responses to these emotions, you can get a healthier heart in the process, too. We’ve listed some ways you can get started.

We often think of depression as making someone feel “down,” but it can sometimes show up as cognitive symptoms — for example, trouble with adapting to new information or thinking through a solution to a problem. Researchers recently determined that several common depression medications are not effective at relieving cognitive symptoms. But there are several things people with depression can try to help return themselves to their usual level of cognitive functioning.

Doctors are often hesitant to prescribe newer drugs. We simply can’t know everything about them until the experiences of early adopters tell us what they’re really like. Such is the case with thiazolidinediones. Some of the more recent diabetes drugs fell out of favor, but a new study suggests that may be helpful for very specific types of patients.
