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 bacteria metabolites directly extend the lifespan of host flies

Gut microbiota influences multiple aspects of host physiology, including metabolic and immune functions.

Cornell study reveals hidden nutritional trade-offs in healthy food labels

A new analysis of nearly 150,000 food and beverage products launched in the United States over the past decade, found that products bearing health-related claims are not only not consistently healthier, they are sometimes less nutritious.

GLP-1 drugs may influence chronic pain through gut-brain and immune pathways

Researchers reviewed evidence linking GLP-1 and GLP-1 receptor agonists to chronic pain modulation through gut microbial, neuroimmune, vagal, and metabolic pathways, with the strongest clinical evidence currently involving knee osteoarthritis and idiopathic intracranial hypertension headache. Much of the proposed biology remains supported by preclinical research, and human studies have yet to establish that GLP-1RA-induced changes in the gut microbiome directly cause pain relief.

First foods bring an early functional shift in the infant gut microbiome

Researchers analyzing paired gut microbiome samples from 125 Irish infants found that complementary feeding was associated with early changes in microbial composition and metabolic potential, including an increased capacity for complex carbohydrate metabolism. Breastfeeding duration was more closely associated with microbial community development than the timing of solid-food introduction, while formula-fed infants showed more extensive functional pathway changes after solids were introduced.

Frailty linked to greater cognitive impairment risk in men with chronic kidney disease

New research from the University of Colorado Anschutz Department of Medicine is shedding light on how women and men with chronic kidney disease (CKD) may fare differently as they age and their disease progresses.

Obesity disrupts ILC2 metabolism through increased fatty acid uptake

A group of innate immune cells, known as group 2 lymphoid cells (ILC2), are essential for maintaining a stable metabolism in adipose tissue. Obesity significantly impairs the number and function of ILC2 cells, leading to the progression of metabolism-related inflammation.

Industry ties widespread among authors challenging ultra-processed food classification

A growing body of research links higher consumption of ultra-processed foods with poorer health. Much of that research relies on a food classification system called Nova, which categorizes foods by the degree and purpose of industrial processing.

A child's gut microbiome may offer early clues to type 1 diabetes risk

Researchers tracking 887 children at high genetic risk of type 1 diabetes identified three distinct patterns of gut microbiome maturation during early childhood. One pattern was associated with substantially higher risk of islet autoantibody seroconversion or type 1 diabetes, while host genetic background altered the risk associated with another pattern.

A chemical used in BPA-free products may have a connection to diabetes control

In adults with type 2 diabetes receiving oral glucose-lowering therapy, higher plasma BPS concentrations were associated with higher HbA1c after accounting for demographic factors, medication adherence, and diet, whereas BPA was not associated with HbA1c. The BPS association was modest and no longer statistically significant after further adjustment for BPA, BMI, and physical fitness, supporting the need for larger studies to determine whether reducing exposure could improve glycemic control.

New 3D lipid atlas maps the chemistry of mouse brains

The brain is often described in terms of cells and wiring. However, much of it is made of lipids that form the membranes of neurons, wrap nerve fibers with myelin, and help brain cells send and receive signals.

What links smoking, body fat, mental health, genes, and heart risk? Inflammation may be part of the answer

In a large UK Biobank study, higher levels of the chronic inflammation marker GlycA were associated with smaller heart chambers, thicker heart walls, impaired diastolic function, reduced stroke volume, and a 43% higher risk of major adverse cardiovascular events in the highest versus lowest GlycA group. Genetic susceptibility also modified the associations between environmental exposures, inflammation, and cardiovascular risk, while inflammatory proteins in the IL-1, TNF, and IL-6 pathways statistically mediated several of these associations.

Aging population drives rise in smoking-related mortality risks

Smoking kills. But why does smoking seem more likely to kill now than a few decades ago? In 1987, a smoker had a 3.4% chance of dying within five years. By 2013, a smoker had a 4.9% chance of drying within five years.

Children who ate healthier plant foods had slightly lower blood pressure later

Researchers followed 3,990 Dutch children for an average of 1.6 years and found that higher healthful plant-based diet scores were associated with modestly lower blood pressure and total cholesterol. Children with higher unhealthful plant-based diet scores had lower estimated food costs and distinct metabolite profiles, while healthful scores showed no clear cost association.
