Multivitamins boost key vitamin levels, but do they improve your health?

A scoping review of 157 clinical trial reports found that multivitamins consistently improved circulating levels of folate, vitamin B6, and vitamin B12, while other nutritional and clinical effects varied by formulation, population, and baseline nutritional status. Selected prenatal and cognitive outcomes improved in some trials, but evidence for cardiovascular disease prevention was largely negative, and the review could not establish the overall certainty of clinical benefits.

Fish, shellfish or seaweed? A Korean study found striking differences in chemical exposure

A national study of 4,279 Korean adults found that higher finfish consumption was associated with increased blood concentrations of PFAS, PCBs, and mercury, while shellfish showed narrower associations with three PFAS. Persistent chemical mixtures were also associated with modest increases in liver health biomarkers, and mediation analysis identified a positive PFAS-related pathway, although finfish intake was not significantly associated with GGT overall.

Too little or too much iodine may push immunity off balance

This narrative review finds that adequate iodine supports thyroid hormone signaling, leukocyte metabolism, antioxidant defenses, and antimicrobial activity in humans and domesticated mammals. Both deficiency and sustained excess may impair immunity or promote thyroid inflammation, but precise immune-specific intake thresholds remain uncertain.

Meat and dairy cuts may improve health without raising food costs

A Scottish microsimulation study found that reducing meat and dairy intake, especially red meat among high consumers, could improve modeled health and environmental outcomes without increasing diet costs. However, some nutrient intakes, particularly calcium and iodine, declined, highlighting the need for carefully planned substitutions and fortified alternatives.

Dutch study shows why plant-based eating can miss key nutrients

A Dutch dietary modeling study found that replacing major animal-based protein sources with plant-based substitutes reduced protein, EAA, vitamin, and mineral intake across age groups. Older adults, adolescents, children, and women were especially vulnerable to shortfalls, highlighting the need for planned substitutions, fortified foods, and age-specific dietary guidance.

Thyroid hormone profiles provide critical prognostic clues for patients facing liver failure

Early and accurate prognostic assessment is crucial to prevent disease progression in liver failure. Thyroid hormones (THs), particularly triiodothyronine (T3), are key metabolic regulators and play an important role in liver regeneration. Liver failure is frequently complicated by non‑thyroidal illness syndrome (NTIS), characterized by low T3 with normal or slightly elevated TSH and T4.

Can diet influence thyroid disease? A major review points to Mediterranean-style eating

This review found that thyroid health depends on more than iodine alone, with selenium, iron, zinc, vitamins, omega-3s, and overall eating patterns all shaping thyroid function and autoimmunity. It also concluded that Mediterranean-style diets are linked to more favorable thyroid outcomes, while unnecessary restrictive diets offer little benefit without a clear medical indication.
