Heart-healthy habits also prevent cancer, Alzheimer’s, COPD, other diseases, Emory study finds

A new study from Emory University reveals that maintaining optimal cardiovascular health can significantly improve overall physical and psychological well-being.
Published today in the Journal of the American Heart Association, the study synthesizes findings from nearly 500 peer-reviewed studies. It confirms that the benefits of heart-healthy behaviors extend far beyond the heart, positively impacting brain function, vision, hearing, muscle strength, and even reducing the risk of chronic diseases such as cancer and dementia.
“While we recently learned that heart-health and brain health are closely tied, in this review we found that almost every organ system and bodily function from head to toe benefit from a heart-healthy lifestyle,” says Liliana Aguayo, PhD, MPH, research assistant professor at the Emory University Nell Hodgson Woodruff School of Nursing and core faculty member at Emory’s Global Diabetes Research Center, who led the study.
The review is the first of its kind to systematically examine how the American Heart Association’s Life’s Simple 7™ metrics — which include not smoking, healthy eating, regular physical activity, maintaining a healthy weight, and managing blood pressure, cholesterol, and blood sugar — influence health outcomes across multiple organ systems. The updated Life’s Essential 8™ also includes sleep as a key factor.
Among the key findings were that those with heart-healthy habits:
Were more likely to maintain their brain and lung function, vision and hearing, and keep their teeth and muscle strength as they age.
Experienced lower levels of cortisol and stress and lower frequencies of several chronic diseases, including cancer, COPD, pneumonia, Alzheimer’s disease, dementia, fatty liver disease, type 2 diabetes, depression, and kidney and end-stage renal disease.
Had a higher self-reported quality of life and a lower risk of adverse pregnancy outcomes, sleep-disordered breathing, metabolic syndrome, erectile dysfunction, functional disability and mobility problems, and all-cause mortality.
Experienced lower medical expenditures, health care utilization, and non-cardiovascular disease costs.
The study was supported in part by the American Heart Association and the National Institutes of Health. It calls for further research in underrepresented populations, including children and pregnant women, and emphasizes the need to understand how even minor lifestyle improvements yield significant health benefits.

A team of University of Florida scientists has been awarded a $1 million grant from the National Science Foundation to tackle one of South Florida’s most urgent environmental threats: groundwater flooding and saltwater intrusion caused by sea level rise.
During the three-year project, scientists on a multidisciplinary team at UF’s Institute of Food and Agricultural Sciences (UF/IFAS), will develop a decision-support system to help local leaders make science-based, cost-effective choices about land use, infrastructure, climate adaptation and flooding mitigation.

New research published in Cell has found that the environment inside our bodies, specifically, the pH level within cells, has a powerful influence on the immune system. The research team identified a key molecular sensor that detects changes in intracellular pH and helps regulate the body’s immune defense. This sensor affects how cells respond to bacterial infections and may also influence susceptibility to inflammatory diseases and cancer. These findings open up a new way of thinking about ...

RIVERSIDE, Calif. -- Inhaling agricultural dust may pose significant risks to gut health for workers in animal agriculture, a University of California, Riverside, study has found.
Led by Declan McCole, a professor of biomedical sciences in the UCR School of Medicine, the study expands on prior findings that hog farm dust causes airway inflammation. The researchers now report in the Journal of Applied Toxicology that inhaling this dust also alters the gut microbiome and impairs intestinal function, including increased “leaky gut” or intestinal permeability. Leaky ...

A new international study suggests that ancient viral DNA embedded in our genome, which were long dismissed as genetic “junk”, may actually play powerful roles in regulating gene expression. Focusing on a family of sequences called MER11, researchers from Japan, China, Canada, and the US have shown that these elements have evolved to influence how genes turn on and off, particularly in early human development.
Transposable elements (TEs) are repetitive DNA sequences in the genome that originated from ancient viruses. Over millions of years, they spread throughout the genome via copy-and-paste mechanisms. Today, TEs make up nearly half of the human genome. While they ...

Osaka, Japan – Ulcerative colitis (UC) causes misery for millions worldwide. It affects the large intestine, causing pain, cramping, and frequent bowel movements with bloody diarrhea. Although some people go through periods when they feel well, the disease will suddenly flare up, causing another cycle of pain, diarrhea, and weight loss. There is currently no cure.
The intestinal flora plays a vital role in UC, but the exact role is unclear. In healthy people, the intestinal flora contains a wide variety of microbes that help digestion and provide benefits for the whole body. In contrast, the intestinal flora of people with UC is unbalanced, with fewer beneficial microbes ...

Chinese researchers have recently challenged the long-held belief that "all life depends on sunlight." In a study published in Science Advances, the researchers identified how microbes in deep subsurface areas can derive energy from chemical reactions driven by crustal faulting, offering critical insights into life deep below Earth's surface.
The research was led by Prof. HE Hongping, a member of the Chinese Academy of Sciences (CAS), and Prof. ZHU Jianxi, both from the Guangzhou Institute of Geochemistry of CAS.
Long regarded as inhospitable to life ...

Everyone knows that if you want to enjoy the full experience of the dawn chorus in the forests of Central Europe, or carry out scientific research on bird species, you have to get up very early in the morning. Until now however, detailed data about daily and seasonal patterns in birdsong have only been available for a few species, as the observations required are time-consuming. A research team from the University of Göttingen and the Northwest German Forest Research Institute has now, for the first time, analysed the song ...
