A study of more than 400,000 people tracked for up to 24 years finds that those who got their dietary fat from plants versus animals had significantly lower odds of dying during the study period. Plant-based fats’ benefit included a reduced odds for deaths due to heart disease, the research showed. Conversely, the study “provides evidence that diets high in animal-based fats, including dairy and eggs, are associated with elevated risks of overall and cardiovascular disease mortality,” concluded a team led by Dr. Demetrius Albanes, of the U.S. National Cancer Institute. As the researchers noted, the composition of fats found in plant sources — grains, vegetables, beans or nuts — differs greatly from that sourced from animals. “Plant-based fats are recognized for their greater composition of monounsaturated fatty acids [MUFAs] and polyunsaturated fatty acids [PUFAs], whereas animal-based fats are characterized by a higher proportion of saturated fatty acids [SFAs],” the team explained. Bodies need fat to live, but U.S. dietary guidelines say that cutting down on saturated fats and replacing them with unsaturated fats is a healthy move. How much would that help folks over the long term? To find out, Albanes’ team looked at dietary and health data collected from 1995 through 2019 as part of the National Institutes of Health AARP Diet and Health Study. The analysis included data on 407,531 adults who…  read on >  read on >

An apple a day, along with a healthy serving of vegetables, could become a first line of treatment for hypertension, new research suggests. Diet plays a large role in overall health, and the study confirmed that a diet high in fruits and vegetables lowers blood pressure while improving both heart and kidney health. And although most modern diets include animal products, which produce high levels of unhealthy acid in the body, fruits and vegetables can help neutralize that acid. “It’s important for us to remember that the usual diets that we eat in modern societies contain much more animal products like meats than fruits and vegetables,” said lead study author Dr. Donald Wesson, a professor of internal medicine at the University of Texas at Austin’s Medical School. “So, when we eat a diet like we do in modern societies, more animal products like meat than fruits and vegetables, we have an acid-producing diet.” In the study, published Aug. 6 in the American Journal of Medicine, 153 patients with primary hypertension who also had very high levels of blood acid were divided into three groups: those who added 2 to 4 cups of fruits and vegetables to their daily diet; those who took sodium bicarbonate (baking soda) tablets; or those who received standard blood pressure treatment and medications. The patients were followed for five years. What…  read on >  read on >

Does your kid suffer from wheezing that returns again and again? They might be suffering from a “silent” viral lung infection that would be better treated by changing up their medications, a new study finds. Nearly a quarter of children and teens with severe wheezing have undetected lung infections, researchers reported recently in the Journal of Allergy and Clinical Immunology. Unfortunately, these infections won’t respond to corticosteroids commonly used to treat wheezing, researchers said. In fact, higher doses of steroids might put children at higher risk of lingering lung inflammation, as well as other known side effects of those drugs. “While steroids can help some children with wheeze, many children in the study showed no patterns of inflammation that would improve with steroids,” said lead researcher Dr. Gerald Teague, a pediatric pulmonologist with the University of Virginia School of Medicine. Instead, these kids should be treated with medications that target viruses and symptoms of viral infection, Teague said. “I advise the parents of my patients that have wheeze episodes that are triggered by colds should be treated with anti-inflammatory medications that build immunity to viruses, such as azithromycin,” Teague said in a university news release. “They look surprised that we would use an antibiotic for a viral infection, but, in fact, azithromycin bolsters the immune response to viruses in a positive way,” Teague added.

Pregnant women and new moms have better access to treatment for mood disorders, thanks to Obamacare, a new study finds. More women received treatment for their pregnancy-related depression or anxiety after the Affordable Care Act (ACA) went into effect in 2014, researchers reported Aug. 9 in the journal JAMA Network Open. However, researchers said more can be done to improve treatment for conditions like postpartum depression. About 10% of women with private insurance received therapy in 2019-2020 for pregnancy-related anxiety or depression, a slight increase over pre-ACA numbers, researchers found. Unfortunately, about 25% of pregnant women and new mothers suffered from a mood disorder in 2019, researchers noted. That means many women did not get the mental health care that could help them and their babies, said lead researcher Kara Zivin, a professor of psychiatry, obstetrics and gynecology with the University of Michigan. “The gap between mental and physical health care closed slightly over time, and cost barriers decreased marginally,” Zivin said in a university news release. This slow increase in treatment following the ACA is likely due to a combination of factors, including a shortage of mental health providers, under-diagnosis of pregnancy-related mood disorders and stigma against seeking therapy, Zivin said. “In this high-risk population, and in the context of what we know about the impact of mental health conditions on maternal mortality, many…  read on >  read on >

As Americans sweat through another scorching summer, one expert warns that while extreme heat can cause physical harm it can also wreak havoc with your mental health. Sizzling temperatures can make anyone irritable, but it can be far worse for some, especially those with mental health conditions, said Dr. Asim Shah, executive vice chair in the Menninger Department of Psychiatry and Behavioral Sciences at Baylor College of Medicine in Houston. Excessive heat can trigger feelings of anger, irritability, aggression, discomfort, stress and fatigue because of its impact on serotonin, the neurotransmitter that regulates your sleep, mood and behaviors, Shah noted. The most vulnerable groups include people with preexisting mental health conditions and people who abuse alcohol or other drugs.  “All mental illnesses increase with heat because it results in more fatigue, irritability and anxiety, and it can exacerbate depressive episodes,” Shah explained in a Baylor news release. What are the signs of impending trouble? They tend to start with irritability, decreased motivation, aggressive behavior and sometimes mental fogging. In worse cases, confusion and disorientation occur, Shah noted. While avoiding the heat may not be possible, Shah recommends hydrating and keeping your head covered when going outside. If it gets too hot, pour some water on your head to cool down and try doing things in the shade. If you normally go for walks outside, try walking in the mall or…  read on >  read on >

Women exposed to TikTok videos that make eating disorders look cool and glamorous tend to have worse body image, a new study finds. These videos include what researchers call “pro-anorexia” clips, as well as other videos focused on weight loss. “Our study showed that less than 10 minutes of exposure to implicit and explicit pro-anorexia TikTok content had immediate negative consequences for body image states and internalization of appearance ideals,” wrote study co-authors Madison Blackburn and Rachel Hogg, from Charles Sturt University in Australia. TikTok is incredibly popular among young users worldwide, and its algorithm creates a customized “For You” page based on user preferences. That means that if girls and young women show a liking for weight loss-oriented videos, such clips can quickly flood their TikTok feed. To understand the impact of all this on viewers’ psyches, Blackburn and Hogg surveyed 273 women between the ages of 18 and 28. They queried the young women on how much time they spent on TikTok, and also assessed symptoms of disordered eating (conditions such as anorexia and bulimia). These conditions also included what’s known as orthorexia: An unhealthy fixation on restricted diets that aim to eliminate “unhealthy” or “impure” foods. The women were then randomized to one of two groups. One group watched seven to eight minutes of TikTok clips focused on disordered eating — for…  read on >  read on >

Pollen is a known trigger for seasonal allergies and asthma, but new research suggests that certain plant species release pollen that are especially tough on asthmatics. Species-specific pollen alerts could help keep people with asthma safe, the Cornell University researchers reasoned. “Even though the percent of asthma-related emergency department visits associated with pollen overall was only a few percent on an annual basis, at certain times of year when particular types of pollen were spiking, we sometimes saw up to almost 20% of visits were due to pollen,” said study lead author Daniel Katz. He’s an assistant professor at Cornell’s School of Integrative Plant Science Soil and Crop Sciences. His team tracked nearly 175,000 emergency department visits recorded by the Texas Department of State Health Services between 2015 and 2020. They focused on people living within 15 miles of one of eight pollen monitoring stations. Viruses and pollen can each help trigger an asthma attack, Katz noted. “Sometimes the timing of when viruses were prevalent changed,” he said in a Cornell news release, “and sometimes the timing of when pollen was in the air changed. So, because of this natural variability, we were able to better untangle what was contributing to these asthma-related emergency department visits.” Pollen from one species of tree, the Ashe juniper, was a clear culprit in exacerbating asthma, the study found. In…  read on >  read on >

People with a genetic predisposition for high cholesterol can lower their levels by taking fish oil supplements, a new study shows. The results indicate that lifestyle can be a powerful influence on artery-clogging cholesterol, even if a person’s genetics tends to make those levels higher, researchers said. “Recent advances in genetic studies have allowed us to predict someone’s genetic risk of high cholesterol,” said lead researcher Yitang Sun, a doctoral graduate from the University of Georgia’s Department of Genetics. “But the current prediction has room for improvement because it does not consider individual differences in lifestyles, such as taking fish oil supplements,” Sun added in a university news release. About 1 in 4 Americans — more than 86 million — have high cholesterol, the researchers said in background notes. Millions more are at risk for high cholesterol because of their genetics, the researchers added. For the study, researchers used genetic data on more than 441,000 British residents to calculate each person’s genetic likelihood of high levels of cholesterol. The study participants are taking part in a large-scale research project called the UK Biobank. As part of that project, the people also reported in a questionnaire whether they take fish oil supplements and provided a blood sample for a cholesterol check. Results show that participants taking fish oil had lower blood cholesterol levels than would be…  read on >  read on >

Kids and teens around the world are consuming more sugary drinks, increasing their risk of future health problems, a new study finds. Young people consumed nearly 23% more sugar-sweetened beverages in 2018 compared to 1990, according to the report published Aug. 7 in the BMJ. “Sugary beverages increase weight gain and risk of obesity, so even though kids don’t often develop diabetes or cardiovascular disease when they are young, there could be significant impacts later in life,” said lead researcher Laura Lara-Castor. She’s a postdoctoral scholar in nutritional epidemiology at the University of Washington. The study provides the first global estimates of sugary drink intake by kids and teens, researchers said. For the study, researchers analyzed data from more than 1,200 surveys completed during the three-decade study period. The data assessed the dietary habits of children from 185 countries. The research team specifically looked at consumption of soda, juice drinks, energy drinks, sports drinks and home-sweetened fruit drinks like aquas frescas. Their definition of sugary drinks did not include 100% fruit juices, diet sodas or sweetened milks. Sugar-sweetened beverage intake averaged 3.6 servings a week globally, and ranged from 1.3 servings a week in South Asia to 9.1 in Latin America and the Caribbean. Children and teens in 56 countries representing 238 million young people – about 10% of the global youth population – averaged…  read on >  read on >

Remember your besties from high school? Sure, they made a lasting impression, but science suggests they influenced the trajectory of your health, too. It’s not that far-fetched: Your friends carry genes that may or may nor predispose them to mental health issues ranging from addiction to anxiety and depression. That can influence the mental health of the people in their friend circle, according to researchers at Rutgers University in New Jersey. “Peers’ genetic predispositions for psychiatric and substance use disorders are associated with an individual’s own risk of developing the same disorders in young adulthood,” said study lead author Jessica Salvatore. “What our data exemplifies is the long reach of social genetic effects,” she said in a Rutgers news release. Salvatore is an associate professor of psychiatry at the university. It’s a relatively new field of research called socio-genomics: How one person’s genetic makeup (“genotype”) can influence a wider network of people. Just how powerful is the socio-genomic effect? To find out, Salvatore’s group looked at Swedish data on over 1.5 million individuals born in Sweden between 1980 and 1998. They then pinpointed exactly where everyone went to school in their teen years. That was followed up by a deep dive into local medical, pharmacy and legal registries that documented any history of substance use and mental health disorders for the same individuals in adulthood.…  read on >  read on >
