In a cross-sectional analysis of 7,256 adults from the Maastricht Study, researchers found that greater adherence to the DASH and Dutch Healthy Diet patterns was associated with higher very-low-frequency (VLF) heart rate variability power, particularly among participants not taking beta-blockers.

Excessive physical exercise affects more than just the muscles; it can also alter brain chemistry. A new study published in the journal Neuroscience revealed that exhaustive training without adequate rest alters the regulation of dopamine in the hippocampus, a brain region closely linked to memory and the regulation of emotions.
 
   The type of fiber you eat shapes how gut bacteria feed and work togetherThe type of fiber you eat shapes how gut bacteria feed and work together
 
A 2021 review examined how the chemical structure and physical properties of dietary fiber influence which gut bacteria can break it down and how microbial species compete and cooperate during fermentation. The authors described how these interactions contribute to short-chain fatty acid production, while emphasizing the need for further research involving intact plant foods to understand their implications for human health.
 
 Can broccoli sprouts help with insulin resistance? New review offers clues
 
Can broccoli sprouts help with insulin resistance? New review offers cluesA review published in the British Journal of Nutrition examines how carotenoids and bioactive compounds in Brassicaceae microgreens may influence obesity, insulin resistance, and type 2 diabetes through metabolic and inflammatory pathways. Small human trials involving broccoli sprouts have reported improvements in selected metabolic markers, but larger, longer-term studies are needed to establish their clinical benefits.

 Mayo Clinic enters new medical era with precure research
 
Mayo Clinic enters new medical era with precure researchMayo Clinic researchers are uncovering the earliest shifts in disease biology - long before symptoms appear - revealing how disease takes root and opening new possibilities to identify, predict and potentially prevent disease before symptoms develop.
 
 
 Younger adults in America's famous Blue Zone are eating differently
 
Younger adults in America's famous Blue Zone are eating differentlyA cross-sectional study of 615 adults in the Loma Linda Blue Zone area and surrounding communities found that vegetarian diets were more common among older adults and Seventh-day Adventists, with vegetarians also reporting significantly lower BMI than non-vegetarians.
 
 
 High-fat diets in mouse parents alter offspring brain development
 
High-fat diets in mouse parents alter offspring brain developmentResearchers fed breeding pairs of mice five diets with different fat and sugar contents to examine how parental nutrition affects offspring brain development. High-fat diets, alone or combined with high sugar, delayed early motor development and altered brain structure in young adult offspring, while the high-sugar-only diet produced no significant changes in individual brain regions after correction for multiple comparisons.
 
 
 Extreme heat and cold hit some people far harder, and it's not just about illness
 
Extreme heat and cold hit some people far harder, and it's not just about illnessResearchers analysing 285,444 adults in Finland and the UK found that excess mortality associated with extreme heat and cold was more than tenfold higher among people with both pre-existing medical conditions and socioeconomic disadvantage than among those with neither or only one vulnerability.
 
 
 Testosterone shows no evidence of improving menopausal brain fog
 
Testosterone shows no evidence of improving menopausal brain fogPublished in Reproduction and Fertility, the review examined five existing studies of women aged 41 to 65 to understand whether testosterone treatment improves thinking and memory in women during and after menopause.
 
 
 Study identifies molecular links between menopause and brain aging
 
Study identifies molecular links between menopause and brain agingResearchers at UC Santa Barbara, UC San Francisco and international collaborators are uncovering the cascade of molecular events that happen when women undergo menopause, a time of life marked by endocrine changes and symptoms like hot flashes, brain fog and sleep disturbances.
