Strawberries could help reduce harmful inflammation in the colonUniversity of Massachusetts, August 20, 202

Inflammatory bowel disease (IBD) is a set of painful conditions that can cause severe diarrhea and fatigue. Treatments can include medications and surgery. But now researchers report that a simple dietary intervention could mitigate colonic inflammation and improve gut health. In this case, a strawberry—or rather, less than a cupful of strawberries—a day could help keep the doctor away.

The dietary consumption of fruits and vegetables has been associated with a lowered risk of IBD. To establish an effective and practical approach to decrease colonic inflammation in both IBD patients and the general population, Xiao and his team at the University of Massachusetts Amherst focused on strawberries due to their wide consumption. 

The researchers found that dietary consumption of whole strawberries at a dose equivalent to as low as three-quarters of a cup of strawberries per day in humans significantly suppressed symptoms like body weight loss and bloody diarrhea in mice with IBD. Strawberry treatments also diminished inflammatory responses in the mice's colonic tissue.

But decreased inflammation wasn't the strawberry's only conferred benefit during this study.  Following the dietary treatments of whole strawberries, the researchers observed a reversal of that unhealthy microbiota composition in the IBD mice. Xiao's team also obtained experimental data that indicated strawberries might impact abnormal metabolic pathways in the IBD mice, which in turn could lead to the decreased colonic inflammation they observed.

Higher diet quality relates to decelerated epigenetic aging Tufts University, August 1, 2022DNA methylation–based epigenetic age measures have been used as biological aging markers and are associated with a healthy lifespan. Few population-based studies have examined the relation between diet and epigenetic age acceleration. We aimed to investigate the relation between diet quality and epigenetic age acceleration.

We analyzed data from 1995 participants (mean age, 67 years; 55% women) of the Framingham Heart Study Offspring Cohort. Cross-sectional associations between the Dietary Approaches to Stop Hypertension (DASH) score and 3 whole-blood DNA methylation–derived epigenetic age acceleration measures—Dunedin Pace of Aging Methylation (DunedinPoAm), GrimAge acceleration (GrimAA), and PhenoAge acceleration (PhenoAA)—were examined.Conclusions:  Higher diet quality is associated with slower epigenetic age acceleration, which partially explains the beneficial effect of diet quality on the lifespan. Our findings emphasize that adopting a healthy diet is crucial for maintaining healthy aging.

Feeling anxious or blue? Ultra-processed foods may be to blameFlorida Atlantic University, August 25, 2022

Do you love those sugary-sweet beverages, reconstituted meat products and packaged snacks? You may want to reconsider based on a new study that explored whether individuals who consume higher amounts of ultra-processed food have more adverse mental health symptoms.

Researchers from Florida Atlantic University's Schmidt College of Medicine and collaborators explored a nationally representative sample of the United States population to determine if individuals who consume high amounts of ultra-processed foods report significantly more adverse mental health symptoms including depression, anxiety and mentally unhealthy days.  They measured mild depression, number of mental unhealthy days and number of anxious days in 10,359 adults 18 and older from the U.S. National Health and Nutrition Examination Survey.

Results of the study, published in the journal Public Health Nutrition, showed that individuals who consumed the most ultra-processed foods as compared with those who consumed the least amount had statistically significant increases in the adverse mental health symptoms of mild depression, "mentally unhealthy days" and "
