Green tea extract promotes gut health, lowers blood sugar

Ohio State University, July 26, 2022New research in people with a cluster of heart disease risk factors has shown that consuming green tea extract for four weeks can reduce blood sugar levels and improve gut health by lowering inflammation and decreasing “leaky gut.”Researchers said this is the first study assessing whether the health risks linked to the condition known as metabolic syndrome, which affects about one-third of Americans, may be diminished by green tea’s anti-inflammatory benefits in the gut.”There is much evidence that greater consumption of green tea is associated with good levels of cholesterol, glucose and triglycerides, but no studies have linked its benefits at the gut to those health factors,” said Richard Bruno, senior study author and professor of human nutrition at The Ohio State University.In the new study, green tea extract also lowered blood sugar, or glucose, and decreased gut inflammation and permeability in healthy people—an unexpected finding.

“What this tells us is that within one month we’re able to lower blood glucose in both people with metabolic syndrome and healthy people, and the lowering of bloodglucose appears to be related to decreasing leaky gut and decreasing gut inflammation—regardless of health status,” Bruno said.”We did not attempt to cure metabolic syndrome with a one-month study,” he said. “But based on what we know about the causal factors behind metabolic syndrome, there is potential for green tea to be acting at least in part at the gut level to alleviate the risk for either developing it or reversing it if you already have metabolic syndrome.”

Blood vessels can actually get better with age 

Study finds that arteries adapt to oxidative stress caused by agingUniversity of Missouri, July 21, 2022Although the causes of many age-related diseases remain unknown, oxidative stress is thought to be the main culprit. Oxidative stress has been linked to cardiovascular and neurodegenerative diseases including diabetes, hypertension and age-related cancers. However, researchers at the University of Missouri found that aging actually offered significant protection against oxidative stress. These findings suggest that aging may trigger an adaptive response to counteract the effects of oxidative stress on blood vessels.”Molecules known as reactive oxygen species, or ROS, play an important role in regulating cellular function,” said Steven Segal, a professor of medical pharmacology and physiology at the MU School of Medicine and senior author of the study. “However, the overproduction of ROS can help create a condition referred to as oxidative stress, which can alter the function of cells and interfere with their growth and reproduction.””We studied the endothelium from resistance arteries of male mice at 4 months and 24 months of age, which correspond to humans in their early 20s and mid-60s,” Segal said. “We first studied the endothelium under resting conditions and in the absence of oxidative stress. We then simulated oxidative stress by adding hydrogen peroxide. When oxidative stress was induced for 20 minutes, the endothelial cells of the younger mice had abnormal increases in calcium when compared to the endothelial cells of the older mice. This finding is important because when calcium gets too high, cells can be severely damaged.” 

When oxidative stress was extended to 60 minutes, Segal’s team found that the death of endothelial cells in the younger mice was seven times greater than those from the older mice. These findings indicated that with advancing age, the endothelium had adapted to preserve cellular integrity when confronted with oxidative stress.Our study suggests that blood vessels adapt during the aging process to regulate ROS and minimize cell death when subjected to an abrupt increase in oxidative stress. This adaptation helps to ensure that the arteries of older individuals can still do their jobs.” 

Elevated tween screen time linked to disruptive behavior disorders

University of California, San Francisco, July 26, 2022Tweens who spend more time on screens have a higher likelihood of developing disruptive behavior disorders, with social media having an especially strong influence, a new UC San Francisco-led study published in the Journal of Child Psychology and Psychiatry found.Social media use was most likely to be linked to conduct disorder, while other forms of screen use—such as watching videos and television, playing video games, and texting—were more likely to be associated with oppositional defiant disorder (ODD).Conduct disorder is characterized by violating others’ basic rights or societal rules with actions such as bullying, vandalism and stealing, while ODD is marked by a pattern of angry or irritable mood, argumentative or defiant behavior, and vindictiveness.Researchers collected data on screen use, then evaluated for behavior disorders one year later. Each hour of social media was linked with a 62% higher prevalence of conduct disorder, while television, video games, video chat, and texting were linked with a 14% to 21% higher prevalence of ODD.In another recent study, Nagata and colleagues found that adolescents are so attached to their phones—the main vehicle for screen time—that they report losing track of time when using their phone (47.5%) and will interrupt whatever they are doing when contacted by phone (31%).The average amount of screen time was four hours per day, with the most time spent watching/streaming TV shows/movies (1.3 hours on average), playing videogames (1.1 hours), and watching/streaming videos (1 hour).  In fact, four hours a day was a threshold, with time above four hours associated with a 69% higher prevalence of conduct disorder and a 46% higher prevalence of ODD.

Cocoa shown to reduce blood pressure and arterial stiffness in study

University of Surrey (UK), July 26, 2022

Cocoa flavanols have previously been found to lower blood pressure and arterial stiffnessas much as some blood pressure medication. However, how effective flavanols are in everyday life in reducing blood pressure has remained unknown, as previous studies in this area have been performed in tightly controlled experimental settings.

Surrey’s new research reduces concerns that cocoa as a treatment for raised blood pressure could pose health risks by decreasing blood pressure when it is not raised, paving the way for it to be potentially used in clinical practice.

In the first study of its kind study, researchers set out to investigate the use of flavanols, a compound found in cocoa, in lowering blood pressure and arterial stiffness in individuals outside of clinical settings.

For several days, eleven healthy participants consumed, on alternating days, either six cocoa flavanol capsules or six placebo capsules containing brown sugar. Participants were provided with an upper arm blood pressure monitor and a finger clip measuring pulse wave velocity (PWV) which gauges levels of arterial stiffness.

Measurements of blood pressure and PWV were taken prior to consumption of the capsules and every 30 minutes after ingestion for the first three hours, and then hourly for the remaining nine hours. Researchers found that blood pressure and arterial stiffness were only lowered in participants if it was high, and there was no effect when the blood pressure was low in the morning.

Professor Heiss added, “The positive impact cocoa flavanols have on our cardiovascular system, in particular, blood vessel function and blood pressure, is undeniable. Doctors often fear that some blood pressure tablets can decrease the blood pressure too much on some days.

Greater potassium intake linked to lower blood pressure in women

Amsterdam University Medical Center, July 25 2022. 

A study  in European Heart Journal found an association between consuming a higher amount of potassium and lower blood pressure among women with a high intake of sodium. “It is well known that high salt consumption is associated with elevated blood pressure and a raised risk of heart attacks and strokes,” noted study author Liffert Vogt, MD, PhD, of Amsterdam University Medical Center. “Health advice has focused on limiting salt intake but this is difficult to achieve when our diets include processed foods. Potassium helps the body excrete more sodium in the urine.”

The study included 11,267 men and 13,696 women who enrolled in England’s EPIC-Norfolk study between 1993 and 1997. Some participants were being treated for hypertension. Sodium and potassium intake were estimated from urinary levels of these minerals and categorized as low, medium or high. 

Increased potassium intake was associated with declining blood pressure among women with high sodium intake. In this group, each 1 gram increase in potassium consumption was associated with a 2.4 mmHg decrease in systolic blood pressure. 

During a median follow-up of 19.5 years, 54.5% of the men and women experienced cardiovascular disease events. Men whose potassium intake was among the top one-third of participants had a 7% lower risk of hospitalization or death caused by cardiovascular disease compared to men whose intake was among the lowest third. Among women whose potassium intake was highest, the risk was 11% lower. 

Elderberry benefits air travelers 

Griffith University, July 21, 2022

The negative health effects of international air travel are well documented but now it seems that the common elderberry can provide some relief.

Associate Professor Evelin Tiralongo and Dr Shirley Wee from Griffith’s Menzies Health Institute Queensland (MHIQ) have completed a clinical trial showing that an elderberry supplement can provide some protection from cold and flu-like symptoms following long-haul flights.

Intercontinental air travel can be stressful and affect a passenger’s physical and psychological wellbeing. Whilst jet lag and fatigue remain the best known problems, holidaymakers also often experience upper respiratory symptoms.

The randomised, double-blind placebo controlled clinical trial was conducted with 312 economy class passengers travelling from Australia to an overseas destination. Cold episodes, cold duration and symptoms were recorded in a daily diary and participants also completed surveys before, during and after travel.

“We found that most cold episodes occurred in the placebo group. However, the placebo group had a significantly higher number of cold episode days, and the symptom score in the placebo group over these days was also significantly higher,” says Associate Professor Tiralongo.

The trial used capsules containing 300mg of a standardised, proprietary membrane-filtered elderberry extract which has shown to be effective in working against respiratory bacteria and influenza viruses.
