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.

Ketogenic diet excels at reversing prediabetes and fatty liver

There is no shortage of popular diets to try, and they can generally produce weight loss if followed to the letter. But are all diet plans created equal in terms of reducing the cardiometabolic risks that come with obesity, such as Type 2 diabetes and liver disease?

Can caffeine make you mentally sharper in the morning? This study tested the idea

In a controlled crossover study of 51 recreationally active young men with low habitual caffeine intake, researchers tested whether 300 mg of caffeine taken about an hour before morning testing affected cognition, mood, temperature, appetite, and related outcomes, with reactive agility assessed in 27 participants. Caffeine did not improve cognitive or reactive agility performance or meaningfully alter mood, tiredness, appetite, or thermoregulation under the study conditions.

Breast milk fats may reflect more than the fats a mother eats

A cross-sectional study of 109 breastfeeding women in the Netherlands found that maternal intakes of omega-3 and omega-6 PUFAs and trans fats were associated with corresponding fatty acid proportions in human milk. The researchers also identified links involving dietary fiber, diet quality and several micronutrients, although whether these relationships reflect direct biological effects or broader dietary patterns remains uncertain.

Tea, berries and dark chocolate featured in a diet linked to lower Parkinson’s risk

A prospective UK Biobank study of 123,655 adults found that a dietary pattern richer in flavonoid-containing foods was modestly associated with a lower incidence of hospital-recorded Parkinson’s disease. The association was strongest among those with the highest flavonoid diet scores, while exploratory proteomic and transcriptomic analyses pointed to possible neuroimmune and cell-adhesion pathways but did not establish causality or mechanism.

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.
