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.

Traditional Inuit Diet: Foods, Nutrition, and Health Effects

Traditional Inuit diets combine nutrient-dense marine and terrestrial country foods that remain important sources of protein, vitamin D, vitamin B12, iron, and other essential nutrients. The transition toward market foods is occurring alongside changes in cardiometabolic health, micronutrient intake, and gut microbiome patterns, while food insecurity, socioeconomic conditions, physical activity, colonial processes, and environmental change complicate the relationship between diet and health.

Gut microbial catalog reveals systemic inflammation drivers in spinal injury

Scientists exploring the links between a spinal cord injury, inflammation and immune function have turned their attention to a genome-level analysis of the gut microbial community, with early study results offering hints at potential new approaches to aid healing.

Why do we turn to comfort food? A survey of 1,203 adults offers clues

A cross-sectional study of 1,203 UK adults found that stronger expectations of positive emotions from high-fat, salt and/or sugar foods were weakly associated with poorer diet quality and more frequent comfort eating. Negative emotional expectations about many foods also tracked with comfort eating, but the study did not establish whether eating these foods actually changed mood.

Discarded fruit and vegetable parts offer overlooked fiber benefits

Most of us routinely discard the peels, skins, stalks, and seeds of fruits and vegetables at mealtime. But new research from King's College London suggests these scraps could be a valuable – and overlooked – source of dietary fiber, offering potential benefits for both public health and the environment.

Major studies identify accurate non-invasive tests for liver disease

Two major international studies have delivered the strongest evidence to date on which non-invasive tests can accurately diagnose and measure the severity of metabolic dysfunction-associated steatotic liver disease (MASLD) and its more severe form, MASH, reducing reliance on liver biopsy.

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.

Brief dietary changes may prime the immune system for inflammation

Scientists have long known that diet shapes the immune system. Now, a UC San Francisco team has found that even a brief dietary change can substantially change how the body responds to skin irritation, at least in mice.

Worried nuts will cause weight gain? A large review puts that concern in perspective

A systematic review and meta-analysis of randomized trials found that eating nuts modestly reduced body fat and improved cholesterol levels without significantly changing body weight. The review did not establish that nuts rich in monounsaturated fats offered greater body-composition benefits than those rich in polyunsaturated fats.

Can broccoli sprouts help with insulin resistance? New review offers clues

A review published in the British Journal of Nutrition examines how carotenoids and bioactive compounds in Brassicaceae microgreens may influence obesity, insulin resistance, and type 2 diabetes through metabolic and inflammatory pathways. Small human trials involving broccoli sprouts have reported improvements in selected metabolic markers, but larger, longer-term studies are needed to establish their 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.

New study reveals why colorectal cancer is more aggressive in youth

Dana-Farber Cancer Institute researchers, along with Mass General Brigham researchers from the Gene Lay Institute of Immunology and Inflammation, and the Broad Institute, have uncovered biological clues to why colorectal cancer can behave more aggressively in younger people.

Limited app use adds a twist to a nurse-led dementia risk trial

A cluster-randomized trial involving 403 Australian adults aged 45–65 found that a 12-month nurse-led behavioral intervention supported by a mobile app modestly improved estimated dementia risk scores compared with brief counseling and usual care. The study found no significant improvements in cognitive performance or other secondary outcomes, leaving its long-term effects on dementia prevention uncertain.

Identical twins showed a survival divide when only one had Parkinson’s

Researchers followed 54 twin pairs discordant for Parkinson’s disease and found substantially higher 10-year mortality among affected twins, including in genetically identical pairs. They also observed more frequent constipation among affected twins, but dietary and nutritional differences were limited, with secondary findings requiring confirmation.

High-fat diets in mouse parents alter offspring brain development

Researchers fed breeding pairs of mice five diets with different fat and sugar contents to examine how parental nutrition affects offspring brain development. High-fat diets, alone or combined with high sugar, delayed early motor development and altered brain structure in young adult offspring, while the high-sugar-only diet produced no significant changes in individual brain regions after correction for multiple comparisons.

Ketones may change sleep patterns, but not always for the better

Researchers reviewed animal and human studies and found that ketone bodies may affect sleep stages through energy metabolism and cellular signaling, with the clearest direct evidence involving acetoacetate in mice. They reported mixed human findings and called for controlled studies to separate ketone-specific effects from changes linked to diet, disease, circadian timing, and physiological stress.
