People trying to adopt a healthier diet probably aren’t the best judges of how well they’re actually eating, a new study discovers. Only about 1 in 4 people could accurately estimate how healthy they were eating when asked to assess their diet after a year spent trying to lose weight, researchers found. Worse, only 1 in 10 people understood how their diet had actually changed during that year, with most assuming they’d made much greater strides than they actually had. “There’s not very good agreement between what they perceive their diet quality to be and what we’ve calculated their diet quality to be. They’re also overestimating the amount of change that they’ve made in their diet quality,” said lead researcher Jessica Cheng. She’s a postdoctoral research fellow in epidemiology at the Harvard T.H. Chan School of Public Health in Boston. “And so that was really the big takeaway here, that there might be some disconnect among people trying to diet with both how healthy they think their diet is and how much change they think they’ve made in their diet over the course of attempting to lose weight,” Cheng added. Cheng will present these findings at this weekend’s annual meeting of the American Heart Association, held in Chicago and virtually. Findings presented at medical meetings are considered preliminary until published in a peer-reviewed journal. Nearly… read on > read on >

MONDAY, Oct. 31, 2022 (HealthDay News) – It could be harder to fill a prescription for the widely used antibiotic amoxicillin because of a shortage that appears to be linked to an ongoing surge in RSV infections across the United States. Supplies of amoxicillin oral solution, which is typically used in children, are low, the U.S. Food and Drug Administration warned Friday. One issue could be that the pharmacy has the drug in stock, but not in the strength needed for the prescription, so it may require some back and forth between the pharmacy and the prescriber, CNN reported. “I think it’s going to be challenging for doctors and prescribers to give their patients a prescription that they’ll then be able to get filled, because pharmacies are going to have a variety of different strengths in stock, and you hate to have that delay of the back and forth, especially for an antibiotic they usually want to get started pretty quick. So I think it’s going to be a frustrating shortage,” Erin Fox, a senior pharmacy director at University of Utah Health, told CNN. In the meantime, the FDA is working with manufacturers to prevent further shortages or reduce the effects of any delays, CNN reported. The American Society of Health-System Pharmacists said it started hearing about shortages of both tablets and oral solutions about… read on > read on >

Intermittent fasting has taken off as a way to lose weight without having to limit types of a food a person eats. But there was little research on how eating only during a few hours of the day and then only drinking water might affect female reproductive hormones. A new study shows that while hormones do change with intermittent fasting, it might not harm fertility. “We’ve observed thousands of pre- and postmenopausal women through different alternate-day fasting and time-restricted eating strategies. All it’s doing is making people eat less,” said Krista Varady, a professor of nutrition at the University of Illinois Chicago. “By shortening that eating window, you’re just naturally cutting calories.” Much of the negative information on intermittent fasting has come from studies on mice or rats, she said, calling for more research of the effects on people. For this study, the researchers followed women with obesity for eight weeks. They ate a “warrior diet,” which was four or six hours of eating without counting calories followed by 18 or 20 hours of water and nothing else. Researchers then compared the women’s hormone levels to those of a control group. Levels of sex-binding globulin hormone, a protein that carries reproductive hormones throughout the body, did not change. Neither did levels of testosterone and androstenedione, which the body uses to produce both testosterone and estrogen.… read on > read on >

People at risk for developing diabetes could help themselves now by eating fewer carbs, according to new research. While low-carb diets are a common next step for someone diagnosed with the disease, people who are prediabetic or with diabetes not treated with medication don’t need to wait to cut back and see benefits to their blood sugar levels. “The key message is that a low-carbohydrate diet, if maintained, might be a useful approach for preventing and treating type 2 diabetes, though more research is needed,” said lead author Kirsten Dorans. She’s an assistant professor of epidemiology at Tulane University School of Public Health and Tropical Medicine in New Orleans. For the study, the researchers studied two groups of 75 people each. In one, participants were assigned to a low-carb diet. The other ate as usual. Six months later, the low-carb diet group had greater drops in hemoglobin A1C, which is a marker for blood sugar levels. That group also lost weight and had lower fasting blood sugar levels. While the study doesn’t prove that a low-carb diet prevents diabetes, it opens the door to further research on how to work through health risks of those with prediabetes and diabetes not treated by medication, Dorans said. “We already know that a low-carbohydrate diet is one dietary approach used among people who have type 2 diabetes, but… read on > read on >

Controlling high blood pressure in older adults may be one of the “best bets” for reducing the risk of developing dementia, Australian researchers report. “Given population aging and the substantial costs of caring for people with dementia, even a small reduction could have considerable global impact,” said researcher Ruth Peters, an associate professor at the University of New South Wales (UNSW) Sydney and program lead for dementia in the George Institute’s Global Brain Health Initiative. In the study of more than 28,000 people, her team found strong evidence that lowering blood pressure could cut dementia risk. Five double-blind, placebo-controlled randomized trials were analyzed that included individuals from 20 countries. The trials used different treatments to lower blood pressure. The researchers followed patients until the development of dementia. Patients were an average age of 69 and mid-range follow-up was about four years. “We found there was a significant effect of treatment in lowering the odds of dementia associated with a sustained reduction in blood pressure in this older population,” Peters said in a George Institute news release. “Our results imply a broadly linear relationship between blood pressure reduction and lower risk of dementia, regardless of which type of treatment was used.” Without significant dementia treatment breakthroughs, reducing risks may help. An estimated 50 million people live with dementia worldwide, and the numbers could triple by 2050.… read on > read on >

Cronobacter sakazakii has been in the news as the cause of infant infections and the reason for a U.S. baby formula recall and resulting shortage this year. Infections are rare and the bacteria is harmless for most people. Yet it can be dangerous or even life-threatening for infants, especially those who are younger than 2 months old, are premature, are immunocompromised or have low birth weight. The U.S. Food and Drug Administration offers some tips for staying safe from this germ, which can live on most surfaces and survive easily in dry food and drink, such as starches, herbal teas and infant formula powder. The bacteria can also live on bottles and come into homes and factories on hands or the soles of someone’s shoes. While liquid formulas go through certain sterilizing treatments during production, powders do not, according to the FDA. So, one way to avoid the bacteria is to use ready-to-feed infant liquid formula, as recommended by the U.S. Centers for Disease Control and Prevention, for infants who are at higher risk. Another is to prepare powdered formula with water that is at least 158 degrees Fahrenheit, then allow it to cool before feeding an infant. This option isn’t possible for certain metabolic and specialty products, which warn against heating above 100 degrees F because it could result in a loss of vitamins… read on > read on >

Even when eating nutritiously, healthy aging depends on moderating the number of calories you take in. Surprisingly, studies show that if you follow a healthy diet, but eat more than an average number of calories, you won’t fare any better in terms of healthy aging than people who follow the traditional Western diet. You want a lifelong diet plan that provides micronutrients, fiber and antioxidants while still limiting calories. That means whether you count calories or portion sizes, it’s important to keep track of all high-calorie foods, even the healthful ones. Here are some examples. While plant oils — such as walnut, olive, safflower, sunflower, grapeseed and sesame oils — are better for you than butter with all its saturated fat, tablespoon for tablespoon, oils actually have more calories — 120 to 130 calories compared to butter’s 100. Use an oil spray to coat pans before cooking to conserve calories when you really need to use oil. When eating a rainbow of veggies, winter squash and sweet potatoes are great choices in the orange color range, but 4 ounces of squash have only 44 calories compared to 84 calories for the same amount of sweet potatoes. If you need a large portion to feel full, eating squash will allow you twice the volume for the same number of calories. Among the most nutrient-dense fruits, a… read on >

Americans’ love affair with fast food continues, with 1 in every 3 adults chowing down on the fare on any given day. That’s the finding from a new report from the U.S. Centers for Disease Control and Prevention. When asked by researchers, 37 percent of adults said they’d eaten fast food at least once over the past 24 hours. There was one surprise: Bucking the notion that poorer Americans favor fast food the most, the report found that intake actually rose with income. For example, while about 32 percent of lower-income folks ate fast food daily, more than 36 percent of middle-income consumers had fast food on a given day, as did 42 percent of those with higher incomes, the report found. Whatever your income bracket, fast food probably isn’t doing your health any favors. That’s because it “has been associated with increased intake of calories, fat and sodium,” the CDC team said. All that adds up to widening waistlines and hardening arteries, one nutritionist warned. “Most fast food is not good for our bodies,” said Liz Weinandy, a registered dietitian at Ohio State University’s Wexner Medical Center. “The more of it we eat, the more likely we are to be overweight or obese and have increased risk for several diseases like type 2 diabetes, heart disease and metabolic syndrome when talking to patients,” she… read on >

Weight loss depends on eating fewer calories than your body uses up. But when you eat those calories could make a difference that you’ll see on the scale. An Italian study found that you can boost weight loss by about 25 percent just by eating 70 percent of each day’s calories between breakfast and lunch, including a mid-morning snack, and the other 30 percent as an afternoon snack and dinner. The researchers used the heart-healthy Mediterranean diet for their study. Participants all cut their intake by 600 calories a day. Their calorie breakdown was 55 percent carbohydrates, 30 percent fat and 15 percent protein, with over 30 grams of fiber daily. At the end of three months, the participants who ate 70 percent of their daily calories through lunch lost 18 pounds compared to 14 pounds lost by those who ate just 55 percent of their calories through lunch. Plus, they lost more body fat and used insulin more effectively, which can help ward off diabetes. It will take some effort to rebalance your calories, especially if you’re used to eating more later in the day and evening. But the results could be more than worth the switch. Key guidelines for following the Mediterranean diet: Most of the foods you eat should be plant-based, such as vegetables, fruits, nuts and seeds. Use plant-based oils, notably… read on >

You’ve probably heard about the high-carb diet and the low-carb diet, but a new study suggests a moderate-carb diet could be the key to longevity. Researchers followed more than 15,000 people in the United States for a median of 25 years and found that low-carb diets (fewer than 40 percent of calories from carbohydrates) and high-carb diets (more than 70 percent of calories) were associated with an increased risk of premature death. Moderate consumption of carbohydrates (50 to 55 percent of calories) was associated with the lowest risk of early death. “This work provides the most comprehensive study of carbohydrate intake that has been done to date, and helps us better understand the relationship between the specific components of diet and long-term health,” said senior study author Dr. Scott Solomon, of Brigham and Women’s Hospital and Harvard Medical School in Boston. The researchers estimated that from age 50, people eating a moderate-carb diet would live another 33 years, four years longer than those with very low carb consumption, and one year longer than those with high carb consumption. The investigators also found that all low-carb diets may not be equal. Eating more animal-based proteins and fats from foods like beef, lamb, pork, chicken and cheese instead of carbohydrates was associated with a greater risk of early death, while eating more plant-based proteins and fats from… read on >
