When you’re diagnosed with diabetes, your doctor is likely to start you on a program to lower blood sugar and help insulin work more efficiently — a regimen that may include a modified diet, exercise and possibly medication. Starting (or ramping up) an exercise program can be the hardest of all these lifestyle changes. Typical exercise guidelines to help manage type 2 diabetes recommend 150 minutes a week of moderate to vigorous aerobic exercise, plus strength training on two or three days. Meeting these goals, especially exercising for 30 minutes on most days, is a stumbling block for people who aren’t used to working out. And, unfortunately, many people with diabetes stay sedentary. But a study published in the journal Diabetes Care found an alternative that may be less taxing and more effective. The study looked at whether short but very frequent bouts of walking or strength training — three minutes every half-hour during an eight-hour workday — could improve the health of diabetics. For the walking study, participants walked on a flat treadmill at a pace of two miles per hour for each of their 16 daily three-minute stints (roughly 1/10 of a mile or 200 to 250 steps, depending on your stride). For the strength training, each three-minute stint included 20-second segments alternating half-squats, calf raises, glute contractions and alternating knee raises, using… read on >

With research finding that the body prefers calcium from food, not supplements, it can be a challenge to meet daily requirements if you’re lactose-intolerant. On average, adults need about 1,000 milligrams of calcium a day. Fortunately, there are choices within many food groups that deliver on calcium. Leafy greens are a great calcium source, and at the top of the list are cooked spinach, collard and turnip greens. Salad lovers, reach for raw kale. Calcium Content in Greens Cooked spinach, collard greens and turnip greens, 1 cup: 200 mg Raw kale, 1 cup: 90 mg Among legumes, beans and white beans in particular are calcium-rich, as are green soybeans, better known as edamame. Some brands of firm tofu made with calcium sulfate have more than half the daily requirement in a serving — check nutrition labels before you buy. Calcium Content in Legumes Cooked white beans, 1 cup: 160 mg Green soybeans, 1 cup: 260 mg Firm tofu, 3.5 ounces: up to 650 mg Some seeds and nuts also pack in calcium along with their unique mix of healthy fats, protein and carbohydrates. Choices include sesame seeds and tahini (sesame seed butter), chia seeds and amaranth, a seed that cooks up like a grain. Enjoy almonds as a snack or spread almond butter on your morning toast. Calcium Content in Seeds and Nuts Sesame seeds,… read on >

High testosterone levels can drastically increase a man’s risk of heart failure and stroke-causing blood clots, a new study reports. Men with a genetic predisposition to high testosterone levels have a nearly eightfold increased risk of heart failure and twice the risk of thromboembolism (blood clots that can block veins or arteries leading to the brain or lungs), researchers found. Although the study focuses on men with naturally high testosterone, it has implications for aging men who are taking testosterone supplements to boost their energy levels and improve their sex drive, experts said. Testosterone sales increased 12-fold globally between 2000 and 2011, particularly in the United States, the researchers said in background notes. “This study serves as a big, red stop sign, a warning that higher circulating levels of testosterone can lead to an increase in cardiovascular events, which are all associated with an increased risk of death,” said Dr. Guy Mintz. He is director of cardiovascular health and lipidology at Northwell Health’s Sandra Atlas Bass Heart Hospital in Manhasset, N.Y. For the study, an international research team, led by C. Mary Schooling from the School of Public Health and Health Policy at City University of New York, analyzed genetic variants that predict testosterone levels, and then assessed whether those variants appeared to influence a person’s risk of blood clots, heart failure or heart attack.… read on >

Foods high in antioxidants — like kale, broccoli and blueberries — could be your ticket to better health, as long as you don’t cook the nutrition out of them. Some like it hot, but not the delicate pigments that give antioxidant-rich veggies their rich colors and health benefits. Choose cooking methods that provide gentle, quick or low heat. For instance, quickly sauteeing vegetables with olive oil for five to eight minutes over medium-high heat will cook them through without destroying all the nutrients. Another option is light roasting at 400 degrees for less than 10 minutes. Gentle baking for less than 30 minutes at 350 degrees will also do the trick. Blending is a fast, no-cook trick that makes these nutrients easier for your body to absorb. Try blending berries, yogurt and a few ice cubes with greens, such as kale and spinach, for a double antioxidant hit for breakfast. For foods with water-soluble nutrients, such as vitamin C, cook with the least amount of water possible. Put just one inch of water in a stockpot, then bring to a boil, add your sliced veggies and cover. Steam three to four minutes until tender-crisp, then serve. Remember that you don’t have to sacrifice flavor to preserve nutrients. This kale recipe is a tasty example. Parmesan Kale 2 teaspoons canola or grapeseed oil 5 ounces chopped… read on >

There’s no doubt that a first baby changes the dynamic between spouses. Here are steps you can take to stay close. First, you need a creative plan to get some sleep. Beyond feeling tired, being sleep-deprived affects your mood and your ability to think clearly. It can lead you to over-react to little things and argue more. Next, prioritize your relationship. Rather than using that last ounce of energy on laundry, enjoy a few minutes of conversation when baby’s napping. Share your thoughts and feelings about your changing world. Don’t stew over them silently and let them come between you. Be honest and admit that parenting is harder than you thought, if that’s what you’re feeling. Being stressed over baby can make you both abandon the little niceties you used to do for each other. But rather than get angry at what you view as slights, acknowledge that you’re in this together and that you each may be struggling, even if in different ways. When your partner does something positive, be appreciative — everyone responds to being acknowledged. When people come to see the baby, don’t feel that you have to entertain them. Ask a close family member or friend to babysit, even if you both stay at home, to give you together time without having to jump up at the first cry from the… read on >

Can you tell how long you’ll live? For seniors, how fit you are may offer a clearer forecast of life span than traditional markers such as high blood pressure, high cholesterol, diabetes and smoking, a new study suggests. It included more than 6,500 people, age 70 and older, who had an exercise stress test between 1991 and 2009. The test measured their fitness by having them exercise on the treadmill as hard as they could. After the test, participants were tracked for an average of just under 10 years. During the follow-up, 39 percent died. Researchers found that the people who were most fit were more than twice as likely to be alive a decade later than the least fit. Surprisingly, the number of heart disease risk factors was not associated with odds of death. Participants with no risk factors had about the same chance of dying as those with three or more risk factors, according to the study, though researchers only found an association between fitness and life span. “We found fitness is an extremely strong risk predictor of survival in the older age group — that is, regardless of whether you are otherwise healthy or have cardiovascular risk factors, being more fit means you’re more likely to live longer than someone who is less fit,” said lead author Dr. Seamus Whelton. He’s an… read on >

“Athlete’s heart” — an enlarged heart created by intense physical training — is a common and often brushed-off condition within elite and professional sports. But a new study of National Football League players is raising concern about the long-term consequences of athlete’s heart when it comes to retirees who have long left the field. These retirees are as likely to have an enlarged heart as those who’ve recently retired, according to a Tulane University study sponsored by the NFL Player Care Foundation. This runs counter to previous assumptions that an elite player’s enlarged heart would return to normal after stopping the intense training associated with his sport, researchers said. “I think we anticipated as these guys got older, they would actually change from having the enlarged heart back to a more normal-sized heart,” said study senior author Dr. Gregory Stewart, co-director of the Sports Medicine Program at Tulane University in New Orleans. “We didn’t see that.” The researchers are to present their findings at the American College of Cardiology’s (ACC) annual meeting March 16-18, in New Orleans. Research presented at meetings is typically considered preliminary until published in a peer-reviewed journal. Dr. Matthew Martinez, head of the ACC’s Sports and Exercise Cardiology Council, expects the findings to be “provocative.” “You’re seeing bigger and bigger folks running faster and faster,” said Martinez, a cardiologist in Allentown,… read on >

(HealthDay News) — Screen devices such as smartphones and TVs are making children more sedentary, the American Heart Association says. This lack of movement is linked to obesity in young people. Experts recommend that parents limit children aged 2 to 5 to one hour of screen time per day. Older children are also cautioned against too much screen time, although no specific time limit has been noted.

Keto, Paleo, Atkins — there’s no shortage of low-carb diets to try, but new research suggests that over time, living low-carb can raise your risk of a heart condition called atrial fibrillation, or a-fib. People who regularly got fewer than 45 percent of their calories from carbohydrates were 18 percent more likely to develop a-fib than people who ate a moderate amount of carbohydrates (about 45 percent to 52 percent of their calories). The Chinese researchers said the risk of a-fib was raised no matter what types of protein or fat were used to replace carbohydrates. “Extremes of anything aren’t good. Too much carbohydrate is bad and too little is also bad,” explained Dr. Laurence Epstein, system director of electrophysiology at Northwell Health in Manhasset, N.Y. Epstein wasn’t involved with the new study. Atrial fibrillation is a heart rhythm disorder. Instead of the usual heartbeat, the heart sometimes quivers in people with a-fib. Because the heart isn’t pumping properly, blood pools in the heart and can form clots. If a blood clot breaks free, it can reach the brain and cause a stroke, according to the American Heart Association. Although the current study was only designed to find an association, and not a cause-and-effect relationship, Epstein pointed to several reasons a low-carb diet could have negative consequences. He said that one way low-carb diets cause… read on >

The U.S. Food and Drug Administration on Tuesday approved the nasal spray medication esketamine — a relative of the club drug and anesthetic ketamine — for use against severe depression. Sold as Spravato, the fast-acting drug becomes the first new type of medicine approved in years against an illness that plagues millions of Americans. In a statement, the FDA said Spravato should be used in conjunction with an antidepressant pill and is meant only for people whose depression has not responded to at least two other antidepressants. Spravato — a much less potent relative of the illicit club drug “Special K” — comes with other restrictions, the FDA said. Ketamine can induce dissociation (feeling disconnected from one’s surroundings) and sedation. Because Spravato might act similarly for a minority of patients, the FDA said safeguards are warranted. “Because of safety concerns, the drug will only be available through a restricted distribution system and it must be administered in a certified medical office where the health care provider can monitor the patient,” said Dr. Tiffany Farchione. She’s acting director of the Division of Psychiatry Products in the FDA’s Center for Drug Evaluation and Research. Patients will self-administer the nasal spray during visits to a medical clinic, and the spray cannot be taken home. A health care provider will monitor the patient until it is clear that he… read on >
