The time children and teens spend video gaming, scrolling through social media or watching TV could be putting their future heart health at risk, a new study says. Each additional hour of screen time is associated with an increase in heart risk factors like blood pressure, cholesterol and blood sugar levels, researchers reported today in the Journal of the American Heart Association. “It’s a small change per hour, but when screen time accumulates to three, five or even six hours a day, as we saw in many adolescents, that adds up,” lead investigator David Horner, a researcher at the University of Copenhagen in Denmark, said in a news release. “Multiply that across a whole population of children, and you’re looking at a meaningful shift in early cardiometabolic risk that could carry into adulthood,” Horner added. For the study, researchers pooled data from more than 1,000 participants in two Danish studies of childhood health. Each child received a heart health risk score based on factors like waist size, blood pressure, “good” HDL cholesterol, triglycerides and blood sugar, researchers said. Parents reported on the kids’ screen time. Every hour a child or teen spent glued to a screen caused those risk factors to tilt toward the bad, results showed. A child’s sleep patterns contributed to this risk, researchers added. Both shorter sleep duration and hitting the sack…  read on >  read on >

Want to drop some pounds? Drop the ultra-processed foods, a new study says. People lost twice as much weight on a diet with minimally processed foods compared to one with ultra-processed products, even though both diets were nutritionally matched, researchers reported Aug. 4 in the journal Nature Medicine. “The global food system at the moment drives diet-related poor health and obesity, particularly because of the wide availability of cheap, unhealthy food,” researcher Chris van Tulleken, an associate professor with the University College London, said in a news release. “This study highlights the importance of ultra-processing in driving health outcomes in addition to the role of nutrients like fat, salt and sugar,” van Tulleken said. Ultra-processed foods are made mostly from substances extracted from whole foods, like saturated fats, starches and added sugars.  They also contain a wide variety of additives to make them more tasty, attractive and shelf-stable, including colors, emulsifiers, flavors and stabilizers. Examples include packaged baked goods, sugary cereals, frozen pizza, instant soups and deli cold cuts. For this study, researchers recruited 55 adults to take turns eating a diet of minimally processed or ultra-processed eats. For eight weeks, participants ate minimally processed meals like oatmeal or homemade spaghetti Bolognese. Then for another eight weeks, they munched on ultra-processed food like breakfast oat bars or ready-to-eat packaged lasagna. Meals were delivered to the…  read on >  read on >

The U.S. Food and Drug Administration’s (FDA) top vaccine official is stepping down after just three months in a role that upset drug companies, patient groups and some political leaders. Dr. Vinay Prasad will leave the agency to “spend more time with his family,” a spokesperson for the U.S. Department of Health and Human Services (HHS) said in a statement. But two people familiar with the situation told the Associated Press that Prasad was asked to leave after a series of recent controversies. They spoke anonymously to discuss internal matters. Prasad joined the FDA in May from the University of California, San Francisco. He had gained attention for questioning the agency’s current approach on approving new drugs, including COVID-19 vaccines. In recent weeks, some conservative activists like Laura Loomer raised concerns about Prasad’s past statements, including praise for U.S. Sen. Bernie Sanders  (I-Vt.) and criticism of President Donald Trump. “How did this Trump-hating Bernie Bro get into the Trump admin???” Loomer posted on X last week. Prasad has also faced pushback for pausing shipments of the only approved gene therapy for Duchenne’s muscular dystrophy, a fatal muscle-wasting disease that mainly affects young boys, the AP reported. The shipments were briefly stopped after reports of patient deaths. However, they resumed this week following pressure from families who rely on the treatment. Prasad has long questioned the…  read on >  read on >

Experts already know that high consumption of ultra-processed foods is bad news for your health, and new research suggests these foods can raise risks for a major killer: lung cancer. Besides the fact that ultra-processed foods are often high in salt, sugar and fat, people who consumed a lot of these foods also tended to avoid healthier, cancer-fighting fare, researchers noted. “Low consumption of minimally processed foods like fruits, vegetables, fish and whole grains was linked to increased lung cancer risk,” noted a team led by Yongzhong Wu of Chongqing Cancer Hospital, in Chongqing, China.   They published their findings July 29 in the journal Thorax. Ultra-processed foods are made mostly from substances extracted from whole foods, like saturated fats, starches and added sugars. They also contain a wide variety of additives to make them more tasty, attractive and shelf-stable, including colors, emulsifiers, flavors and stabilizers. Examples include packaged baked goods, sugary cereals, ready-to-eat or ready-to-heat products and deli cold cuts. Consumption of ultra-processed foods has already been associated with 32 health problems, including heart disease, obesity, diabetes, some types of cancer and depression.  The new study may add the leading cancer killer, lung cancer, to that list. Wu’s team looked at data from the US Prostate, Lung, Colorectal and Ovarian (PLCO) Cancer Screening Trials.  The trials tracked cancer incidence and deaths between 1993 and 2018…  read on >  read on >

Two years’ involvement in programs focused on healthy eating, regular exercise and “brain training” exercises appears to have helped a wide range of older adults — even those at heightened risk for Alzheimer’s — avoid cognitive decline, a new study finds. The findings, presented Monday at the Alzheimer’s Association International Conference in Toronto, “encourage us to look at the potential for a combination of a lifestyle program and drug treatment as the next frontier in our fight against cognitive decline and possibly dementia,” said Dr. Joanne Pike, president of the Alzheimer’s Association. The research, known as the U.S. Study to Protect Brain Health Through Lifestyle Intervention to Reduce Risk (U.S. POINTER), is funded by the association.  The study involved more than 2,100 people aged 60 to 79 who were enrolled at five academic centers across the U.S.   To qualify for enrollment, people had to have had certain risk factors for cognitive decline — a sedentary lifestyle, a “suboptimal” diet, poorer heart and metabolic health, and a family history of memory impairment.  These at-risk individuals were then asked over two years to help turn some of those risk factors around.  For example, they were asked to abandon their previously unhealthy diets and adopt the MIND diet, known to be especially beneficial for the brain.   They were also asked to get off the couch and meet…  read on >  read on >
