Beneficial gut bacteria found to suppress harmful microbes

Intestinal bacteria are important for human health as they help digest food and regulate immune function. Thus, in recent years, it has become clear that gut microbiota dysbiosis, an imbalance in types and composition of intestinal bacteria, is associated with digestive disorders and other diseases.

Scientists finally define what it means to be flexitarian

Researchers conducted a systematic review to develop a clear, evidence-based definition of the “flexitarian” diet, identifying it as consuming animal products at least once a month but less than once a week. Analysis of 42 countries’ dietary guidelines revealed that while “flexitarian” is not officially recognized, many nations implicitly support plant-forward eating by recommending reduced red meat consumption.

MRI brain scans help identify effective use of self-guided anxiety app

By understanding differences in how people's brains are wired, clinicians may be able to predict who would benefit from a self-guided anxiety care app, according to a new analysis from a clinical trial led by Weill Cornell Medicine and NewYork-Presbyterian investigators.

FAU experts recommend high-potency statins to reduce LDL cholesterol

There is broad consensus that the overall body of evidence shows lowering LDL (low-density lipoprotein) cholesterol provides both statistically significant and clinically meaningful benefits in treating and preventing cardiovascular disease.

New research reveals why fiber-rich diets fuel you better than refined foods

This study quantifies how much energy the human body harvests from gut microbial fermentation of dietary fiber, integrating bacterial physiology, diet, and metagenomic data. Results reveal that dietary fiber, not microbiome composition, mainly determines the amount of short-chain fatty acids absorbed, impacting daily energy and metabolic health.

Virtual memory T cells provide nonspecific immunity for infants early in life

Findings from St. Jude Children's Research Hospital demonstrate that virtual memory T cells, a specialized group of immune cells, provide nonspecific immunity for infants early in life.

Selective impairment of translation contributes to brain aging in killifish

Aging selectively impairs the production of crucial DNA- and RNA-binding proteins, which contributes to hallmarks of aging in the brains of killifish, according to a new study.

Behavioral adaptation precedes morphological change in human evolution

As early humans spread from lush African forests into grasslands, their need for ready sources of energy led them to develop a taste for grassy plants, especially grains and the starchy plant tissue hidden underground.

Saliva testing offers a non-invasive way to detect early metabolic risk

Measuring elevated levels of insulin in blood, called hyperinsulinemia, is a proven way to measure metabolic health and can show risk of developing future health concerns, including Type 2 diabetes, obesity and heart disease.
