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.

Biofortified millet improves toddler gut health without adverse effects

Toddlers who ate iron- and zinc-biofortified pearl millet for nine months did not experience adverse effects typically associated with increased iron intake and developed gut microbiomes with distinct and potentially beneficial changes, according to a new study led by researchers at Cornell University's Joan Klein Jacobs Center for Precision Nutrition and Health.

Inflammatory bowel disease linked to elevated risk of psychiatric disorders

Patients with inflammatory bowel disease (IBD) face a significantly higher risk of psychiatric disorders starting two to three years before diagnosis and lasting up to a decade after, according to a nationwide study to be published in Clinical Gastroenterology and Hepatology.

Mouse study shows how liraglutide briefly rewires gut bacterial communities

Researchers treated male high-fat-fed mice with liraglutide for 14 days, then tracked fecal bacterial communities after a 7-day washout using 16S rRNA sequencing. Liraglutide shifted the microbiome toward Lactobacillus- and Leptogranulimonas-related taxa while reducing several fermentative taxa, but most changes moved back toward baseline after treatment stopped.

NIH funds smartphone platform to improve driving safety for teens

Dr. Jeffrey Keller, Hibernia National Bank/Edward G. Schleider Endowed Chair at LSU's Pennington Biomedical Research Center, and Sara Seifert, president of Minnesota HealthSolutions, have received a new National Institutes of Health Small Business Innovation Research (SBIR) award to develop an innovative digital health platform that will help parents support teenagers with attention-deficit/hyperactivity disorder (ADHD) as they learn to drive.

Better sleep may boost academic and social success in adolescents

A new UC Davis Health study published in Psychological Medicine suggests that when it comes to helping adolescents succeed in school and maintain healthy friendships, sleep may matter more than screen time, exercise or diet.

Exercise helps protect Hispanic adults from late life cognitive decline

Previous studies have examined the associations between adherence to LS7 and cognitive outcomes, with findings suggesting that higher LS7 scores are associated with better cognitive performance, reduced dementia risk and improved brain health.

Researchers suggest a potential therapeutic strategy for muscle loss associated with obesity

Obesity has been linked to skeletal muscle loss and deterioration. While M2 macrophages may play a role in regulating muscle function, the underlying mechanisms remain poorly understood.

Blood filtration method helps clear circulating lipids and toxic microplastics

The machine is not new. Some version of it has run in hospital treatment rooms for about four decades, drawing blood from one arm, separating out the plasma, passing it across a filter or an adsorber, and returning it to the other arm.

Continuous glucose monitors show no proven benefits for healthy people

Continuous glucose monitors are becoming increasingly popular, including among people without diabetes.

Food may taste different on GLP-1 drugs, but taste may not be the reason

The review suggests that patient-reported “taste changes” during GLP-1RA treatment may reflect reduced food enjoyment and motivation rather than consistent impairment of basic taste. The authors propose a sensory-liking-wanting framework while emphasizing that current human evidence remains heterogeneous and largely indirect.

Study links lower vitamin D to mood and cognitive health in adults over 85 with diabetes

Researchers studying 188 adults aged 85 years or older with type 2 diabetes found the lowest serum 25(OH)D concentrations among those with both depressive symptoms and mild cognitive impairment. Lower levels remained associated with having both conditions after adjustment for selected factors, but the cross-sectional study cannot establish causation or a benefit from supplementation.

Restricting select amino acids may mimic protein restriction’s healthy aging benefits

A review finds that restricting protein, particularly methionine, isoleucine, and valine, may improve metabolism and influence key aging pathways, largely in experimental models. Short human studies suggest metabolic benefits, but effects on lifespan remain unknown and restriction may harm people with unmet or increased protein needs.

Large US trial supports silver diamine fluoride for severe early childhood caries

A phase 3 randomized trial of 830 young children with severe early childhood caries found that 38% silver diamine fluoride arrested 54.0% of eligible cavitated dentin lesions at six months, compared with 22.5% after placebo. The noninvasive treatment showed clinically meaningful efficacy, but about half of the lesions remained active, supporting close monitoring and additional preventive care.

Texas A&M study links polyethylene microplastics to fatty liver disease

Microplastics have become nearly impossible to avoid. They have been detected in oceans, drinking water and even the human body, but scientists are still uncovering how they affect human health.

Gut microbiome shifts may begin before Alzheimer’s symptoms appear

A narrative review links reduced SCFA-producing gut bacteria and altered microbial metabolism with Alzheimer’s disease, while early evidence suggests similar changes may appear before cognitive symptoms. Mediterranean, DASH, MIND, and prudent diets are associated with beneficial microbial profiles, but direct evidence connecting diet, the microbiome, and amyloid pathology remains limited.

Daily tomatoes lowered a key marker of liver fat in MASLD trial

An exploratory randomized trial found that 200 g of raw tomatoes plus 50 g of tomato sauce daily for six weeks produced a greater reduction in CAP-defined hepatic steatosis than a tomato-free diet in adults with MASLD. The improvement occurred without major weight or metabolic changes, but larger and longer trials are needed to confirm its clinical significance.

Traditional Japanese medicine for obesity may help reduce age-related tissue fibrosis

A traditional Japanese medicine used for obesity may do more than support weight loss. Researchers at the University of Osaka, working with Kobayashi Pharmaceutical Co., Ltd. investigated whether Bofutsushosan could protect aging tissues from fibrosis - the excessive buildup of scar-like tissue that can make organs stiff and less functional.
