Diet & Nutrition

Food and beverages provide the energy and nutrients you need to improve health, manage disease, and reduce the risk of disease. Complete nutrition requires ingestion and absorption of vitamins, minerals, essential amino acids from protein and essential fatty acids from fat-containing food, also food energy in the form of carbohydrate, protein, and fat. Dietary habits and choices play a significant role in the quality of life, health and longevity.

Dehydrated Foods: Nutrition Facts, Health Benefits, and Safety Risks

Dehydrated foods extend shelf life and improve storage stability by reducing water activity, while modern drying technologies help preserve nutrients, texture, and bioactive compounds more effectively than traditional methods. Careful control of drying conditions, packaging, and storage is essential to minimize nutrient loss, microbial risks, and quality deterioration in dehydrated fruits, vegetables, meats, and ready-to-eat foods.

GLP-1 drugs may reshape obesity care, but clinicians still have questions

Interviews with 11 healthcare professionals in a UK specialist weight management service found generally positive attitudes toward injectable GLP-1 drugs, alongside limited formal training and uncertainty about how the medications should be integrated with behavioral care. Participants anticipated potential benefits for confidence and weight management but also raised concerns about treatment discontinuation, behavioral engagement, and evolving professional responsibilities.

Why living to 100 may depend on far more than diet and exercise

A critical narrative review found that healthy diets, regular physical activity, strong social ties, and psychological well-being can support healthier aging and reduce premature mortality, but none has been shown to reliably determine who reaches 100. The authors argue that exceptional longevity arises from complex interactions among biological resilience, genetics, social and environmental conditions, lifelong exposures, and chance rather than any universal lifestyle formula.

Scientists found a distinct gut microbiome pattern in people with symptomatic diverticular disease

A multicenter Japanese study found that symptomatic uncomplicated diverticular disease (SUDD) was associated with reduced gut microbial diversity, increased abundance of the Ruminococcus gnavus group, and depletion of Coprococcus and other butyrate-producing bacteria. Predictive microbiome analysis also identified enrichment of pathways linked to exopolysaccharide biosynthesis and the cell cycle, although the observational design means these associations cannot establish causality.

A year after women lost weight, researchers saw which health gains lasted and which faded

Diet-induced weight loss significantly reduced predicted 10-year risks of major adverse cardiovascular events and type 2 diabetes in healthy premenopausal women with overweight, regardless of whether aerobic or resistance exercise was added. Some of these gains diminished as weight was partially regained over the following year, although greater exercise adherence was associated with less rebound in predicted diabetes risk.

Researchers traced lifelong obesity resistance in mice back to an early microbial encounter

Natural wild-derived microbiota protected mice against diet-induced obesity across sexes, genetic backgrounds, and age by increasing energy expenditure and promoting a thermogenic program in brown adipose tissue. The effect depended on the immune system’s initial encounter with the microbiota and required CCR2-associated myeloid activity, revealing a long-lasting microbiota-immune-brown fat pathway.

Anti-immigrant policies linked to rising HIV cases among Hispanic populations

Following the Trump administration's 2018 announcement of changes to the public charge rule that would penalize immigrants for using public benefit programs, antisanctuary counties in the US saw a 16.8-percent increase in HIV cases among Hispanic populations, compared to baseline counties.

Consistent meal logging drives major weight loss in app users

The people who log their meals most days of the week lose the most weight. This is the central finding of a peer-reviewed study of 5132 MyNetDiary users, published on August 13, 2026, in the Journal of Medical Internet Research.

What decades of wine research can, and cannot, tell us about health

A narrative review found that moderate wine intake has repeatedly been associated with lower all-cause and cardiovascular mortality, with proposed mechanisms involving ethanol and grape-derived polyphenols, but the evidence remains largely observational and cannot establish causation. The authors argue that drinking pattern, beverage type, age, cancer risk, and risk-modeling choices all influence how the J-shaped association should be interpreted and how alcohol guidelines are developed.

From caffeine to trigonelline, coffee has surprising links to muscle biology

A scoping review of 54 studies found that coffee and several coffee-derived bioactive compounds influence pathways linked to skeletal muscle metabolism, including insulin signaling, mitochondrial function, oxidative stress, inflammation, glucose uptake, and protein turnover. Human studies reported associations with greater muscle mass and lower frailty or functional impairment, but most evidence remains observational or preclinical and cannot establish causality.

The diet-Alzheimer’s connection is more complicated than “eat this, avoid that”

A mini-review finds that dietary patterns may influence Alzheimer’s disease through interconnected pathways involving neuroinflammation, insulin resistance, oxidative stress, blood-brain barrier dysfunction, homocysteine, and the gut-brain axis. The authors argue that genetics, sex, age, physical activity, and socioeconomic context may modify these relationships, supporting more individualized approaches to nutrition research and dementia prevention.

Scientists compared 51 longevity studies to see which aging biomarkers respond most reliably

Researchers analyzing 51 longitudinal intervention studies found that reliable generation 2+ DNA methylation biomarkers, particularly those predicting mortality or pace of aging, were the most responsive to interventions aimed at longevity or healthspan. Pharmacological and lifestyle interventions produced the strongest biomarker changes, but the authors cautioned that responsiveness does not yet establish these measures as validated surrogate endpoints for slower aging or longer life.

Understanding opioid risks can help prevent accidental overdoses

According to numbers calculated from the CDC, approximately 80,000 people died last year from a drug overdose, which represents about 21 deaths per 100,000 residents in the U.S. alone. Overdose deaths are preventable, and in most of the cases we see, they are completely accidental.

Could a daily vinegar drink help with constipation? A small trial offers a clue

A randomized, double-blind trial found that adults with mild constipation who drank a vinegar beverage daily for four weeks had more frequent bowel movements than those receiving placebo. Exploratory findings also suggested earlier improvements in bowel habits, although the small feasibility-based trial requires confirmation in larger and more diverse populations.

Semaglutide’s heart benefits may partly involve reduced inflammation

A prespecified analysis of 17,604 SELECT participants found that higher baseline hsCRP was associated with greater risks of major cardiovascular events and death in people with overweight or obesity and established cardiovascular disease. Semaglutide produced rapid and sustained reductions in hsCRP, with changes emerging before substantial weight loss, although the study could not establish whether reduced inflammation directly mediated its cardiovascular benefits.

A two-year diet trial challenges the idea that weight loss is the only result that matters

In the two-year DELISH randomized trial, adults with obesity achieved modest, sustained weight loss with either an adapted Mediterranean-style program or a commercial weight loss program. The Mediterranean-style intervention produced greater improvements in self-reported diet quality, while 24-month weight loss did not materially differ between groups.

Historic redlining continues limiting healthy food access, study finds

Bad housing, high crime and poor schools are more important than transportation or income when it comes to accessing healthy food in neighborhoods historically subjected to "redlining" - the now-illegal practice once used to refuse loans, insurance or mortgages to people in certain neighborhoods that were disproportionately inhabited by racial and ethnicity minorities.
