Why the same healthy diet may not work the same way for everyone

A review published in Nutrients proposes a seven-pillar precision nutrition framework that combines biological, behavioral, and environmental information to tailor dietary interventions throughout life. The authors identify potential benefits for cardiovascular, respiratory, blood, and sleep health, while emphasizing the need for further clinical trials to establish effective, accessible, and personalized nutritional strategies.

Researchers investigate molecular mechanisms linking high-calorie diets to cognitive decline

The molecular mechanisms linking a high calorie diet to cognitive impairment remain unclear. Researchers at Institute of Science Tokyo, Japan, investigated this association in mice, finding that the diet reduced nuclear protein PQBP1 expression, disrupting the alternative splicing of genes involved in synaptic function.

Not all ultra-processed foods show the same cancer risk

Ultra-processed foods show varied associations with colorectal cancer, underscoring the need for precise research on diet quality and cancer risk factors.

Could eating whey protein before meals help reduce blood sugar spikes?

A narrative review of 57 randomized trials found that milk and dairy products have inconsistent effects on long-term blood sugar control in adults with type 2 diabetes or prediabetes. Whey protein consumed before meals more consistently reduced short-term blood sugar spikes, but further research is needed to establish whether these benefits persist over time.

Fruit and sugary drinks stood out in a three-year study of teenage mental health

A three-year study of 6,537 Australian adolescents found that higher fruit consumption was associated with a lower risk of elevated depression and anxiety symptoms, while greater sugar-sweetened beverage intake was associated with increased risk. Vegetable consumption showed no significant association with either outcome, and the observational findings cannot establish cause and effect.

Researchers use mitochondrial uncouplers to target breast cancer metastasis

Mitochondrial serine catabolic pathway (MSCP), also called serine, glycine, and one-carbon metabolism, is essential for cancer cells to produce amino acids, one-carbon units, and reducing equivalents.

Could ultraprocessed foods affect your brain before you notice?

Ultraprocessed food intake correlates with increased body fat and vascular brain injury in middle-aged adults, though cognitive performance remains unaffected.

Could this flowering plant help people lose body fat?

Lythrum salicaria extract supplementation led to body fat reduction in a clinical trial, suggesting a promising plant-based approach to weight management.

Your age may not tell the whole story about your health, but your blood could

Researchers analyzed plasma metabolites from 18,476 individuals aged 1 to 96 years and developed two metabolomic aging measures to assess biological aging, chronic disease, and mortality risk. Accelerated metabolomic aging was associated with greater risks of chronic disease and death, while a separate mortality-linked measure provided additional information about health status and disease burden beyond conventional clinical assessments.

A CDC survey finds 4 in 5 US teenagers fall short of high heart health scores

A CDC study of 5,192 US high school students found that approximately 80% had low or moderate cardiovascular health scores based on five measures assessed in a national survey. Diet, sleep, and physical activity received the least favorable scores, with differences observed across sex, grade, and racial and ethnic groups.

Study: First 90 days of antipsychotic treatment critical for metabolic changes

The first 90 days after starting antipsychotic treatment are crucial for changes in blood sugar and weight, finds a new study led by UCL researchers.

Scientists reviewed studies covering 1.17 million children and found a major research gap

Researchers identified 104 pregnancy and birth cohorts representing more than 1.17 million children across 41 countries, documenting the availability of data on early-life nutrition and neurodevelopment. Approximately 99% of participants in the income-stratified analysis came from high- or upper-middle-income countries, while differences in data collection and assessment methods complicate future international comparisons.

Losing weight is one thing. Keeping your muscle is another, experts say

The International Society of Sports Nutrition (ISSN) position stand concludes that sustained calorie restriction drives weight loss, while adequate protein intake and resistance training help preserve lean mass. Reviewing intermittent fasting, ketogenic diets, and other dietary approaches, the authors emphasize individualized nutrition plans, body composition, and sustainable weight management rather than rapid weight loss alone.

Coffee, citrus and genetics: What scientists found inside human breast milk

In a bioRxiv preprint, researchers analyzed 458 metabolites in breast milk samples from 349 mothers to investigate how maternal diet, genetics, clinical characteristics, and milk-cell gene expression relate to milk composition. Maternal diet explained the greatest share of metabolite variation among the measured maternal factors, while specific genetic variants and gene-expression patterns were associated with individual metabolites, although the study did not establish effects on infant health.

Your diet may have more to do with your sense of smell than you think

Researchers analyzed dietary patterns and odor identification in 6,690 adults in Italy, finding that healthier plant-rich diets, particularly those emphasizing fruits and vegetables, were associated with better olfactory function and lower odds of hyposmia. Diets emphasizing less healthy plant foods showed the opposite association, although the cross-sectional study could not establish whether diet influences smell or impaired smell affects food choices.

Scientists studied diet and lung cancer in 95,612 adults. One eating pattern stood out

A prospective study of 95,612 U.S. adults found that those with the highest sulfur microbial diet scores had a 23% higher adjusted lung cancer incidence hazard and a 19% higher lung cancer-related mortality hazard than those with the lowest scores. However, the associations weakened after accounting for overall dietary quality and competing causes of death, and the findings do not establish a causal relationship.

Switching to a vegan diet rapidly alters liver metabolism

A team from UNIGE has shown that switching from a vegetarian to a vegan diet is enough to modify the liver’s metabolism within a few days.

Beyond ‘bad’ cholesterol: new clues to the risk of heart disease

Researchers at Chalmers University of Technology, in Sweden, shed new light on the remaining risk of heart disease, even after the known risk factor of ‘bad’ cholesterol is brought down to a healthy level.

Mediterranean-style diet during pregnancy lowers risk of infant colic and eczema

Infants born to mothers who ate a healthy, Mediterranean-style diet during pregnancy were at lower risk for colic and eczema, according to a new study by researchers at Harvard T.H. Chan School of Public Health, Boston Children's Hospital, and Harvard Pilgrim Health Care Institute.
