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.

Why you still want dessert even when you're completely full

A 2026 narrative review examines how food liking (pleasure) and wanting (motivation) interact with hunger and satiety to influence food choices, explaining why certain foods may remain appealing even after a satisfying meal. The authors report that food reward can change independently of hunger under specific conditions, but evidence remains limited that these changes reliably predict subsequent eating or improve weight-management outcomes.

The type of fiber you eat shapes how gut bacteria feed and work together

A 2021 review examined how the chemical structure and physical properties of dietary fiber influence which gut bacteria can break it down and how microbial species compete and cooperate during fermentation. The authors described how these interactions contribute to short-chain fatty acid production, while emphasizing the need for further research involving intact plant foods to understand their implications for human health.

Eating walnuts was linked to higher IgG levels, but what does that mean for health?

A two-year randomized trial involving 474 older adults found that daily consumption of 30–60 grams of walnuts was associated with 6% higher total serum IgG concentrations compared with a control diet, with an 11% difference observed among US participants. Walnut consumption did not significantly affect IgM, MDA-LDL or MDA-LDL-specific antibodies, and whether the modest IgG difference has meaningful cardiovascular benefits remains unknown.

Holistic family surroundings are essential for raising healthy children

A child's health is shaped by more than inherited genes or the food on the table. Family routines, relationships, cultural practices, and everyday conditions—from early school schedules to long commutes—also influence how children grow and thrive, according to an Ateneo de Manila University medical professor and clinician.

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.
