Heart failure is a common ailment afflicting older Americans, and many take drugs called diuretics to rid the body of excess fluid buildup that can impede breathing. Now, a team of Brazilian researchers say that, in some cases, it’s safe for patients with stable heart failure to stop taking diuretic drugs. “Patients don’t like using diuretics because they feel they have to stay at home to use the bathroom and they get cramps,” noted study principal investigator Dr. Luis Rohde, of the Federal University of Rio Grande do Sul in Porto Alegre, Brazil. “Patients would welcome being able to stop this medication,” he said, and the new study suggests it can often be done safely. One U.S. expert who reviewed the new findings stressed that diuretics are key to heart failure care. “Congestive heart failure is one of the most common chronic ailments in the United States, characterized primarily by volume (fluid) overload,” explained Dr. Mohammed Imam. In heart failure, a damaged or weakened heart fails to pump blood as efficiently as it should. “The mainstay of treatment for decades have been diuretics,” said Imam, who directs cardiothoracic surgery at The Heart Institute at Staten Island University Hospital in New York City. Diuretics help patients with heart failure reduce excess fluids that can cause shortness of breath, swollen legs, coughing and weight gain. However, the… read on >

From cappuccinos to cold brew, coffee is a morning must for many Americans, but is it healthy and how much is too much? A University of South Australia study suggests a couple of cups to start your day probably won’t hurt — and may even be good for you. But drinking six or more cups of coffee a day can increase your risk of heart disease by up to 22%, the researchers found. About one in four deaths in the United States is due to heart disease, according to the U.S. Centers for Disease Control and Prevention. Heart disease is the leading cause of death worldwide. That’s why Elina Hypponen and Ang Zhou of the Australian Center for Precision Health in Adelaide set out to discover the point when too much caffeine causes high blood pressure, a key heart disease risk factor. The tipping point: Six 8-ounce cups — each containing 75 milligrams (mg) of caffeine. “Knowing the limits of what’s good for you and what’s not is imperative,” Hypponen said in a university news release. “Overindulge and your health will pay for it,” she added. For the study, the researchers used a U.K. database of more than 300,000 adults, aged 37 to 73, to explore how the caffeine-metabolizing gene (CYP1A2) affected people’s ability to process caffeine and their risk for heart disease. The investigators… read on >

Want to be part of the movement to limit food waste of all kinds? One tasty way is to get the most from all your citrus fruits by using the zest, the brightly colored top layer of peel. Tangy citrus zest is a natural antioxidant. It’s also a “free” food, because it has practically zero calories, yet is full of flavor thanks to the natural oils that give grapefruit, oranges, lemons and others their strong scents. Unlike the underlying white pith, the zest is not bitter. The best way to zest? Pick up an inexpensive super-slim microplane. The tiny grater holes create a fine zest when you run the fruit along its length. They stay sharp, plus the tool is dishwasher safe (though a quick rinse might be all it needs after use). Choose organic citrus to avoid ingesting any pesticides that can linger on the peel. Wash the whole fruit under cold running water, then carefully shave off the fragrant skin, stopping short of the pith. Mix zest with olive oil and minced garlic for a savory, fresh-tasting marinade for chicken. Make flavored cooking oil by stirring citrus zest into a beaker of extra-virgin olive oil. Use zest to enhance baked goods — cut the sugar in traditional recipes by half, then add a teaspoon of zest to add unique flavor. Zest is also… read on >

Vaping is gaining a foothold in an unlikely population: New research shows a growing number of cancer patients are using electronic cigarettes. “The gradual but steady increase is quite striking,” said study author Dr. Nina Sanford, an assistant professor of radiation oncology at UT Southwestern Medical Center in Dallas. “The high prevalence of e-cigarette use among younger cancer patients and survivors is concerning.” E-cigarette use by cancer patients rose from 8.5% in 2014 to nearly 11% in 2017, according to the analysis of federal government data on more than 13,000 patients. Among patients younger than 50, the rate of use rose from 23% in 2014 to 27% in 2017. Use of conventional cigarettes by cancer patients remained stable between 2014 and 2017, according to Sanford. There is little known about e-cigarette use among cancer patients, she added. “Because e-cigarettes are relatively new, we don’t have the long-term data on their side effects yet,” Sanford said in a medical center news release. It’s known that conventional cigarettes can impair healing from surgery and radiation therapy, so it’s possible that e-cigarettes may cause similar problems, she noted. Sanford said patients often ask about e-cigarettes, and she advises them to avoid all kinds of smoking or vaping. “I don’t encourage it, but I also am honest that the jury is still out on what the long-term effects of… read on >

Brittle bones are often seen as a woman’s health issue, but low bone mass may be more common among middle-aged men than generally thought, a small study suggests. The research, of 173 adults aged 35 to 50, found that men and women were equally likely to have low bone mass in the hip. It was found in 28% of men and 26% of women. Those study participants, the researchers said, had osteopenia, or lower-than-normal bone density. In some cases, it progresses to osteoporosis — the brittle-bone disease that makes people vulnerable to fractures. The fact that osteopenia was just as common in men came as a surprise, said researcher Allison Ford, a professor of health and exercise science at the University of Mississippi. Full-blown osteoporosis is clearly more common in women. About one-quarter of U.S. women aged 65 and up have the condition in the hip or lower spine, according to the U.S. Centers for Disease Control and Prevention. That compares with about 5% of men the same age. But, Ford said, the new findings suggest low bone density might be more common in middle-aged men than appreciated. “Low bone mineral density and osteoporosis affect men,” she said. “They should not be overlooked.” Ford suggested men take steps to help ensure their bones stay healthy — including eating a well-balanced diet with enough calcium, getting… read on >

If you’ve ever wondered why emotional distress causes stomach cramps or a mad dash to the bathroom, know that there’s a direct line of communication that runs from your brain to your digestive tract. It’s called the enteric nervous system, and it can have a powerful effect. For instance, when you feel nervous or threatened, digestion can slow or stop so that your body can focus on functions with higher priority — and that might result in cramps or diarrhea. This is a hallmark of the condition called irritable bowel syndrome, or IBS. The brain-gut connection works in both directions. For example, having a digestive condition can make you anxious or cause emotional distress. Plus, that anxiety can then worsen your digestive symptoms. Researchers recently found a connection between depression and the absence of certain good gut bacteria — they can’t yet say which comes first, but it’s clear that there’s some type of relationship. If your gut reacts negatively to emotions and it’s affecting your life, talk to your doctor. Find out if you have a digestive issue that’s causing physical as well as emotional stress, such as IBS, and take steps to treat it. These may involve changes to your diet and other lifestyle habits. Know that the answer doesn’t always have to include drug therapy. To master anxiety regardless of its source,… read on >

Compound strength-training exercises get fast results, because they work many muscle groups at once. Many of these exercises use just your own bodyweight, such as pull-ups, which engage not only the shoulders and all the muscles of your arms, but also those in your back and core. Other exercises can be enhanced by holding a weight or weights. Hand-Held Weight Options Kettlebells Dumbbells or a barbell with or without weight plates Jugs of water Heavy food cans Here are three exercises to try: For the loaded carry, engage your core muscles and hold a weight in each hand. Now simply walk for 30 to 60 seconds, then stop and release the weights. Rest for 60 seconds and then repeat the sequence up to five times. For the classic squat, stand with feet shoulder-width apart, toes slightly turned out. Hold a barbell behind your head, press your shoulders back and engage your core. Keep your back straight as you press your hips behind you and lower your chest toward your thighs. Your thighs move parallel to the floor, but your knees don’t go beyond your feet as they bend. Feet stay flat on floor throughout. Press heels into the floor to push up and return to standing. Note: It will take time to master a full squat. Beginners can start by holding an unweighted barbell.

Exercise apps and fitness trackers are all the rage, and now a new study shows they might actually work. A combination of an exercise app, an activity tracker and personal counseling increased women’s physical activity levels, researchers found. The study of 210 inactive women found that three months of this combined approach increased the number of steps they took each day and their amount of moderate to vigorous physical activity. Even if the women stopped using the mobile phone app after three months, they continued to get more exercise, the findings showed. After the women had gained the skills and knowledge during the initial part of the study, they only needed the fitness tracker, not the app, to continue being more active, the University of California, San Francisco (UCSF) researchers explained. The study was published online May 24 in JAMA Network Open. “Studies show that engaging in at least 150 minutes of moderate-intensity physical activity per week can reduce the risk of cardiovascular disease, type 2 diabetes and certain types of cancer,” said lead author Yoshimi Fukuoka, a professor at the UCSF School of Nursing. “Digital technologies are moving faster than research in transforming the way we promote physical activity and in reducing risks of chronic illness. But, in addition to an activity tracker and mobile app, having activity goals, self-monitoring and accountability are important,”… read on >

Here’s another reason to keep your cholesterol under control: New research suggests that LDL, or “bad,” cholesterol may play a role in the development of early-onset Alzheimer’s. A rare form of the disease that occurs before the age of 65, early-onset Alzheimer’s has previously been linked to a gene mutation involved in how the body processes fats and cholesterol. But that mutation only accounts for a small percentage of cases, the scientists noted. Their new research suggests that “LDL cholesterol levels [also] play a causal role in the pathogenesis of Alzheimer’s disease,” said lead researcher Dr. Thomas Wingo. He’s an assistant professor of neurology at Emory University School of Medicine in Atlanta. “The big question is whether there is a causal link between cholesterol levels in the blood and Alzheimer’s disease risk,” Wingo said. “The existing data is murky on this point. Our current work is focused on testing whether there is a causal link.” Most early-onset Alzheimer’s disease is not explained by known gene mutations, Wingo added. The APOE genetic mutation, called APOE E4, raises levels of LDL cholesterol. High levels of this type of cholesterol can clog arteries, increasing the risk for heart attack and stroke. Other gene mutations associated with early-onset Alzheimer’s are called APP, PSEN1 and PSEN2. But all of these genetic variants are only linked to about 10% of all… read on >

You know how important it is to eat seafood twice a week, but buying fresh fish and shellfish can seem daunting. You’ll find that it’s a lot easier if you remember a few simple rules. When buying whole fish, look for bright, clear eyes. The eyes are the window to a truly fresh fish, because they quickly turn to a dull gray with age. The rest of a fish will also fade as it sits around, so look for vibrant flesh. If you’re considering a fillet that still has the skin on, that skin should look shiny, metallic and clean. Any dullness or discoloration is another sign of age. Finally, a fresh fish should smell like clean water or just slightly briny, never fishy. Under no circumstances should you ever buy a nasty smelling fish — cooking can’t improve a fish past its prime. As for shellfish, buy only at stores with rapid turnover so you can be assured of fresh mussels, clams, oysters and more. Their shells should be tightly closed. If slightly open, they should close quickly if you tap on them — if not, don’t buy them. Also, any mussels or clams that haven’t opened after being cooked are spoiled and must be thrown away. Whether you shop at a dedicated fish store or the fish counter of your local grocery, your… read on >
