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.

Flavorings, colors and sweeteners emerge as UPF markers linked to depression risk

A prospective UK Biobank study of 171,818 adults found that greater estimated exposure to foods containing flavorings, coloring agents, and sweeteners was dose-dependently associated with a higher risk of incident depression over 10.7 years. The findings suggest that specific markers, rather than ultra-processed foods uniformly, may help explain associations between UPF consumption and depression risk.

Researchers found one childhood behavior linked to folic acid use before pregnancy

Researchers analyzed 646 children aged 2–8 years and their 563 mothers to examine whether maternal folic acid supplementation before conception was associated with childhood behavioral difficulties. Preconception supplementation was associated with a 34% lower risk of peer relationship problems, while no significant associations were found for total behavioral difficulties, emotional, conduct, hyperactivity/inattention, or prosocial problems.

Blocking a key protein protects against metabolic liver damage

Obesity-related metabolic liver disease affects hundreds of millions of people worldwide, but only some fraction of those livers develop scarring, become inflamed, and eventually fail. University of Utah researchers have identified a protein, EFHD1, that appears to drive that transition by triggering an out-of-place antiviral immune response.

Could the type of fiber children eat matter for their developing gut microbiome?

A recent study found that different dietary fibers can shape the composition and activity of the gut microbiome during early childhood, with xyloglucan, arabinoxylan, and pectin increasing short-chain fatty acid production in laboratory fermentation experiments. Some fibers also supported gut barrier measures and altered inflammatory responses, while observational data linked higher pectin intake with greater microbial diversity in young children.

Breastmilk from cannabis users showed differences, but cannabis may not be the whole story

A narrative review found that maternal cannabis use may be associated with differences in breastmilk fat, protein, lactose, and the immune factor secretory immunoglobulin A, but evidence comes primarily from only two human studies and remains limited and inconsistent. The authors stress that maternal diet, food security, socioeconomic circumstances, and other forms of adversity could confound these associations and should be incorporated into future research.

A personalized elimination diet changed the gut microbiome in people with migraine

In a 12-week randomized, sham-controlled trial of 98 adults with migraine, eliminating IgG-positive foods altered gut microbial composition and produced a greater reduction in serum zonulin than a sham elimination diet. The microbial changes were associated with previously reported reductions in CGRP and IL-6 and improvements in migraine and sleep, although the authors emphasized that these mechanistic links remain exploratory.

The scale told a similar story across three diets. The liver told a different one

In a randomized controlled trial of people with metabolically unhealthy obesity, approximately 10% weight loss improved insulin sensitivity and several cardiometabolic measures across ketogenic, Mediterranean, and very-low-fat plant-forward diets. However, the very-low-carbohydrate ketogenic diet produced larger improvements in hepatic insulin sensitivity and greater reductions in liver fat and several glucose and insulin measures than the higher-carbohydrate diets.

Experts call for safer weight loss as concerns grow over GLP-1 use

An editorial in Diabetology International argues that inappropriate GLP-1 use should be judged not only by regulatory compliance or off-label prescribing, but also by whether weight reduction is medically safe, nutritionally adequate, and properly supervised. Drawing on Japanese reports of ketosis and ketoacidosis following inappropriate tirzepatide use, the authors call for greater attention to the risks of unsafe weight-loss practices alongside medication-related harms.

People with diabetes may have another reason to protect their cardiovascular health

Better cardiovascular health, measured using Life’s Essential 8, was associated with a lower risk of mild cognitive impairment among people with diabetes after accounting for genetic susceptibility. Associations with dementia varied by genetic risk, while higher LE8 scores were also linked to greater gray matter volume and lower white matter hyperintensity volume.

Your skin may offer clues about how many fruits and vegetables you eat

In an exploratory study of 137 Australian adults, skin yellowness measured by reflectance spectroscopy was associated with combined fruit and vegetable intake, fruit intake alone, total carotenoid intake, body fat percentage and skin color. The findings suggest skin measurements could provide an objective dietary biomarker, but the researchers caution that skin color, ethnicity and other individual characteristics may influence how the measurements are interpreted.

In a natural experiment involving 72,920 propensity-matched US adults aged 60 years and older, recombinant shingles vaccination was associated with a 9% lower cardiovascular disease burden over seven years compared with the live attenuated vaccine. Lower burdens of ischemic heart disease and heart failure were seen in both sexes, while ischemic stroke was significantly lower only among men, supporting further clinical trials and mechanistic studies
