The researchers determined children’s nicotine levels using blood samples taken between 2017 and 2020. The children in the study with the lowest nicotine levels were those who had no exposure to secondhand aerosols of any kind at home. Earlier studies have found similar nicotine exposure among children in homes with cigarette and e-cigarette users. Some of his research has shown much higher nicotine levels in e-cigarette households than in the new study. In 2020, Galiatsatos published what is believed to be the first study to document significant injury in an adult with secondhand e-cigarette exposure.

CNN —GLP-1 medications such as Ozempic and Wegovy may help lower the risk of certain cancers, a new study suggests. About 40% of new cancer diagnoses are associated with excess weight, according to the US Centers for Disease Control and Prevention. The risk was cut by more than half for gallbladder cancer, meningioma, pancreatic cancer and hepatocellular carcinoma, a kind of liver cancer. It was also significantly reduced for ovarian cancer, colorectal cancer, multiple myeloma, esophageal cancer, endometrial cancer and kidney cancer. And GLP-1 medications interact with systems related to insulin production.

He follows the Longevity Diet, created by his colleague and L-Nutra cofounder Valter Longo, a professor of gerontology and director of the USC Longevity Institute. It's mainly a plant-based diet but includes fish a few times a week, plus lots of complex carbohydrates, and healthy fats from nuts, Antoun said. Eat nuts every dayNuts are a good source of plant-based protein, complex carbs, and healthy fats, Antoun said. In a 2023 study published in JAMA Network Open, 22 pairs of twins were randomly assigned either a healthy vegan diet or a healthy omnivorous diet for eight weeks. Have dinner early and breakfast lateAnother part of Longo's Longevity Diet, and the central tenant of L-Nutra's business model, is intermittent fasting.

For this study, researchers analyzed data from the Nurses’ Health Study of more than 45,000 people age 50 or older in 1992 who were also free of chronic disease, according to the study published Tuesday in the journal JAMA Network Open. On the other hand, adding two hours of light physical activity at work added a 6% increase in the odds of healthy aging. Replacing one hour of sitting to watch TV with light physical activity at home or work was associated with better chances of healthy aging, the study showed. More activity and less sitting while watching TV may give you a better chance at healthy aging, a new study showed. “You’re missing out on all that physical activity, which is truly an unbelievable way to reduce cardiovascular risk and blood pressure,” Freeman said.

CNN —Women who closely followed a Mediterranean diet lived much longer than those who did not, according to a new study that followed more than 25,000 women for 25 years. “In this study, adherence to the Mediterranean diet was a proxy for diet quality. Each increase in the adherence to the Mediterranean diet extended life for women, the new study found. In all that data, however, are few details on the specific ways the Mediterranean diet may affect women, especially long-term. “What might be worth noting is that the adherence measure ‘corrects’ for distortions of the Mediterranean diet,” Katz said.

CNN —Younger generations are getting their first periods earlier, and the length of time it takes to become regular is changing — which could point to later health problems, according to a new study. But other research has documented the trend in first menstrual cycles starting at earlier ages over time. Earlier periods might be associated with high body mass index, or BMI, during childhood, Wang said. “This implies that childhood obesity, which has been increasing in the US, might be contributing to people getting their periods earlier,” Wang added. Physicians should evaluate children with early periods or a long duration of irregular cycles to make sure there isn’t an underlying problem, Feinberg said.

CNN —Chemical toxins are everywhere — in our water, food, air and soil. Children born to European mothers exposed to four families of chemicals that disrupt the body’s endocrine (hormone) system had elevated levels of metabolic syndrome at ages 6 to 11. Metabolic syndrome can include obesity, elevated blood pressure, and abnormally high cholesterol and insulin resistance, which is a precursor to type 2 diabetes. Metabolic syndrome is typically associated with adult cardiovascular disease, type 2 diabetes and stroke, but the growing epidemic of childhood obesity has seen symptoms appearing in kids at younger and younger ages. Having metabolic syndrome as a child is highly predictive of chronic disease as an adult, experts say.

The BackgroundFluoride strengthens tooth enamel, and research suggests that drinking water with added fluoride can reduce cavities by up to 25 percent. Most of the women lived in areas with fluoridated water. The researchers measured the fluoride levels in their urine in a single test during the third trimester. And on average, higher fluoride levels in the mothers’ urine were correlated with a greater risk of behavioral problems in the children. That said, the increases in behavioral scores were relatively small — about two points on a scale from 28 to 100 for overall behavioral problems.

CNN —The ultraprocessed foods your kids eat now may be putting them a greater risk for cardiometabolic problems – like heart attack, stroke and diabetes – in adulthood, a new study suggests. Researchers divided the data from the children into three groups based on the amount of ultraprocessed food they ate. “This particular topic, ultraprocessed food consumptions and risk, is a very important topic in kids,” he said. The ultraprocessed foods kids eat now may have lasting impacts, a new study suggests. In places where fresh food might be harder to obtain, ultraprocessed foods are more accessible and inexpensive, Freeman said.

CNN —An influential group of medical experts, the US Preventive Services Task Force, recommended last week that most women receive a mammogram starting at age 40. People should now starting getting mammograms at age 40, according to new recommendations. According to a study in the journal Lancet Oncology, the mortality from breast cancer could be lowered by starting mammograms earlier, at age 40. A woman who has a sister, mother or other first-degree relative with breast cancer has double the average risk of breast cancer.

Olive oil may lower risk of dementia-related death
  + stars: | 2024-05-06 | by ( Kristen Rogers | ) edition.cnn.com   time to read: +5 min
CNN —A daily spoonful of olive oil could lower your risk of dying from dementia, according to a new study by Harvard scientists. Olive oil can be a healthy, tasty addition to foods such as sandwiches and salads. Replacing 5 grams — around 1.2 teaspoons — of margarine or mayonnaise consumed daily with olive oil was associated with an 8% to 14% lower risk of death from dementia. “It is also possible that olive oil has an indirect effect on brain health by benefiting cardiovascular health,” she added. Besides cooking with olive oil, you can also use it to make salad dressings or vinaigrettes, mayonnaise, pesto or bread dip.

UnitedHealth Group struck a deal in March to buy the nine-state doctor group of the struggling hospital system Steward Health Care. AdvertisementDoctors are hot commoditiesIt's tough to lump the many buyers of medical practices together, as they're pursuing different strategies. Insurers like UnitedHealthcare and CVS' Aetna are required by federal law to spend most of the money they collect in premiums on medical care. Plus, running a modern medical practice is expensive, requiring investments in staffing, technology, and electronic health records.

CNN —Flame retardants added for decades to thousands of consumer products in the United States may raise the risk of dying from cancer, according to new research. “The new study links PBDEs to deaths from cancer, building a case for the association between flame retardants and cancer mortality being real,” said Trasande, who researches the impact of plastics, flame retardants and other chemicals on children. Flame retardant chemicals also can pass to developing fetuses via the placenta and to newborns through breast milk, past research has found. In some cases, the industry has replaced these chemicals with newer phosphorus-based flame retardants, Trasande said, adding that researchers are now concerned these chemicals may be linked to cancer as well. When reupholstering older couches or chairs, be sure to replace the old foam with flame retardant-free foam.

The blockbuster diabetes drug Ozempic could be manufactured for less than $5 a month, even as Novo Nordisk charges close to $1,000 per month for the injection in the U.S. before insurance, a study released Wednesday suggests. The study also comes after years of political pressure on Novo Nordisk and other drugmakers to slash high costs of diabetes care, especially insulin. Ozempic can generally be produced for less than various forms of insulin, according to the study published in JAMA Network Open. Novo Nordisk's list price for a monthly package of Ozempic is $935.77 before insurance and other rebates. In a statement on Wednesday, Novo Nordisk declined to provide production costs for Ozempic and its weight loss drug counterpart Wegovy.

Teen pregnancy increases the chances that a young woman will drop out of school and struggle with poverty, research has shown. Teenagers are also more likely to develop serious medical complications during pregnancy. Now a large study in Canada reports another disturbing finding: Women who were pregnant as teenagers are more likely to die before their 31st birthday. The trend was observed among women who had carried teen pregnancies to term, as well as among those who had miscarried. “Some people will argue that we shouldn’t be judgmental about this, but I think we’ve always known intuitively that there’s an age that is too young for pregnancy,” he added.

Sleep is an important lifestyle factor in reducing risk for type 2 diabetes, a new study has found. In terms of risk for type 2 diabetes, there wasn’t a significant difference between those with normal sleep and those who slept six hours. And even for those who ate the healthiest, their diet didn’t offset the effects of insufficient sleep on diabetes risk. The findings are also based on participants’ recollections of their food and sleep habits, according to the study. Confirming a causal relationship “would require randomized trials intervening on sleeping habits to increase sleep time and see if this reduces risk of diabetes in those at risk, e.g.

A study found people on the Atlantic diet had a lower risk of metabolic syndrome and less belly fat. AdvertisementIf you love carbs and want to eat more healthfully, a close neighbor of the Mediterranean diet may be just the thing. The Atlantic diet diet focuses on plenty of longevity-boosting foods like produce, olive oil, beans, seafood, and even some wine. AdvertisementBut the Atlantic diet features even more carbs, specifically whole grains and starchy foods like bread, pasta, and potatoes. Half the participants were randomly assigned to follow a traditional Atlantic diet, and provided with food, cooking classes, and other resources to do so.

What is the Atlantic diet?
  + stars: | 2024-02-13 | by ( Sandee Lamotte | ) edition.cnn.com   time to read: +6 min
CNN —The traditional diet of northern Portugal and northwestern Spain, known as the Southern European Traditional Atlantic Diet, or Atlantic diet for short, may hold some clues to better heart health and a lower risk of dying early from cancer, heart disease or any cause, according to studies conducted in Europe. The diet is based on foods grown or found in that part of the Europe, much like its famous cousin the Mediterranean diet. Because it’s plant-based and locally sourced, the Atlantic diet also helps protect the planet by contributing to the United Nations’ Sustainable Development Goals, the study’s authors noted. Like the Mediterranean diet, the Atlantic diet focuses on home-cooked food served family style, with an emphasis on social interactions between friends and family. However, other studies have shown that not all food groups in the traditional Atlantic diet are beneficial.

Read previewA gentle, low-impact form of exercise may help keep your heart healthy and lower your blood pressure even more than hitting the treadmill, new research suggests. Half the group were randomly assigned to do tai chi, while the other group did cardio exercises such as jogging or cycling. AdvertisementWithin six months, participants who did tai chi saw more improvements in their blood pressure than the cardio group. By the end of the year, the tai chi group had even lower blood pressure, and were significantly more likely to have a healthy blood pressure than their cardio-trained peers, according to the researchers. While more research is needed to understand how it works, the latest study suggests tai chi could be a safe, effective strategy for people of all ages to improve their blood pressure toward healthy levels.

Teen suicide: Study identifies behavioral risk factor

But you should pay more attention since social withdrawal could signal something deeper is going on, a new study has found. Across the globe, 10% to 20% of adolescents experience suicidal thoughts, and suicide is one of the leading causes of death among them, highlighting the need for strengthened prevention efforts. But the current study examined the associations between the long-term trajectory of multiple categories of psychological and behavioral symptoms and suicidal thoughts. But the link between social withdrawal and suicidal thoughts could be explained by the “loss of protective social connections,” according to the study. “If you hear a lot of complaints about aches and pains, it doesn’t (automatically) mean your child is suicidal,” Willard said.

People who predominantly sit at work have a 16% higher risk of mortality from all causes, and a 34% higher risk of mortality from cardiovascular disease. As I sit here typing, I’m wondering what I should make of these study results. CNN: Are you surprised by the findings in this study — a 16% higher mortality from all causes and a 34% higher mortality from cardiovascular disease for people who predominantly sit at work? Studies have also shown that even light activity to break up the periods of prolonged sitting can reduce that risk. People would do a lot to change that habit, as they should when they sit for prolonged periods at work.

CNN —Treating loneliness and social isolation may put people classified as obese at a lower risk for health complications, according to a new study. Social isolation was found to be a greater risk factor for all causes of mortality, including cancer and cardiovascular disease, than depression, anxiety and lifestyle risk factors — which included alcohol, exercise and diet, according to the study. But the findings do point to improving “social isolation as a potential remedy for the reduction of mortality,” he said. “Think of maintaining a social network like any other health-promoting activity: exercising regularly, eating well, looking after yourself,” Canli said. And fatphobia can lead communities to make it harder for people with obesity to feel understood and accepted, she said.

Vegan diets may lead to better heart health and slower aging, suggests a new study of twins. 22 pairs of twins tried either vegan or omnivore diets to control for factors like genetics. While vegan diets may be harder to stick to, you don't have to be strictly plant-based to benefit. One member of each pair of twins was randomly assigned a vegan diet, eating exclusively plant-based foods with no meat, eggs, dairy, or other animal products. However, the vegan participants self-reported that they weren't as happy with their food, which could account for the extra weight loss.

A vegan diet differs from a vegetarian diet in that it eliminates not only animal flesh but dairy, eggs or any other ingredient derived from animals. In each pair, one twin was assigned a vegan diet, while the other was assigned an omnivore diet. “I feel like a lot of people who do a vegan diet think ‘Oh great, soda is vegan. Cutting back on eating meat and animal byproducts can be done slowly, bit by bit. Harvard’s Hu agreed: “While this study showed a vegan diet may provide additional advantages compared to a healthy omnivorous diet, it does not mean that everyone should become a vegan or vegetarian.
