Mediterranean diet benefits identified by SPARC levels

A new study published in Life Metabolism reports that a single post-meal blood biomarker, 1-hour postprandial SPARC (SPARC-1H), can predict who will benefit most from adopting a Mediterranean diet.

Fanconi anemia patients show striking metabolic differences

Experts at Cincinnati Children's have uncovered striking metabolic differences in people with Fanconi anemia (FA), a rare genetic disorder that causes bone marrow failure and dramatically increases cancer risk.

How the gut microbiome links obesity to colorectal cancer

The gut microbiome serves as both a biomarker and therapeutic target in diseases like obesity, metabolic syndrome, and colorectal cancer.

Alternate-day fasting cuts body fat but also reduces muscle

Research reveals that alternate-day fasting reduces body weight and fat but also leads to muscle loss, with whey protein supplementation proving ineffective.

Drinking three to four cups of coffee a day may slow cellular aging

New findings reveal that 3-4 cups of coffee daily may enhance telomere length, potentially slowing cellular aging in individuals with severe mental disorders.

Texture-based analysis of OCT images reveals early retinal changes in diabetes

Diabetic retinopathy (DR) is a leading cause of blindness among working-age adults, affecting more than 130 million people worldwide.

Chronic drinking weakens the blood-brain barrier through the gut

Chronic alcohol consumption disrupts the blood-brain barrier, but Faecalibacterium prausnitzii shows promise in repairing this damage and improving cognition.

SNAP and Medicaid cuts could strip students of school meals

Federal changes to Medicaid and SNAP could limit school meal access for vulnerable students, undermining nutrition equity and increasing administrative strain.

Polyphenol-rich dietary patterns linked to lower cardiovascular disease risk

People who regularly consume polyphenol-rich foods and drinks, such as tea, coffee, berries, cocoa, nuts, whole grains and olive oil, may have better long-term heart health.

Uncovering the hidden metabolic effects of soybean oil

Soybean oil, the most widely consumed cooking oil in the United States and a staple of processed foods, contributes to obesity, at least in mice, through a mechanism scientists are now beginning to understand.

Moderate coffee intake linked to slower biological aging in people with severe mental illness

Drinking a maximum of 3-4 cups of coffee a day may slow the 'biological' ageing of people with severe mental illness, by lengthening their telomeres-indicators of cellular ageing-and giving them the equivalent of 5 extra biological years, compared with non-coffee drinkers, finds research published in the open access journal BMJ Mental Health.

Obesity-related metabolic stress may affect brain health far earlier than expected

For decades, scientists have known that what harms the body often harms the brain. Conditions such as obesity, high blood pressure and insulin resistance strain the body's vascular and metabolic systems.

Global data show why gut microbiomes in industrialized regions look increasingly alike

Researchers studying more than 1 000 adults across 12 countries found that industrialization is one of the strongest forces reshaping the human gut microbiome, reducing diversity and stability. Industrialized and urban populations also showed higher immune and gut stress markers, suggesting physiological consequences of these altered microbial communities.

Long-term calorie restriction can slow cellular markers of brain aging

As the brain ages, cells in the central nervous system experience metabolic dysfunction and increased oxidative damage.

Polyamines restore gut regeneration in aging mice

With aging, the intestine gradually loses its ability to regenerate after damage. An international research team involving the Leibniz Institute on Aging - Fritz Lipmann Institute (FLI) in Jena and the University of Turin has now found that polyamines, small molecules produced naturally in the body, can play a decisive role in this process.
