Food addiction and binge eating disorder show striking clinical overlap that current diagnostic frameworks do not fully capture. In binge eating disorder samples, Yale Food Addiction Scale-defined food addiction has been reported in roughly half of participants. Higher symptom severity is associated with greater impairment.

A nationwide survey reveals that eating meals at irregular times is tied to a higher likelihood of depression. Dietary diversity can cushion this effect, while regularly skipping breakfast amplifies the connection between sporadic eating schedules and low mood.

Scientists at UC Riverside uncovered evidence that compounds beyond THC may influence how the body regulates metabolism and insulin signaling. A preclinical study from the University of California, Riverside offers new insight into a puzzling pattern that scientists have noticed for years: people who use cannabis chronically often have lower body weight and a lower [...]

Creatine research was built on male data. New science shows women may benefit more, especially during perimenopause, when the stakes across muscle, bone, and the brain are highest.

An EHU study says that vitamin D supplements can help to strengthen the immune system, but not to improve athletic performance.

processed meat, frozen meals, snacks, soft drinks, sauces, desserts, and many other supermarket products. Most people rarely notice them, even though they appear in the ingredient lists of foods eaten every day. These additives are mainly used to keep food fresh for longer, prevent mold and bacteria from growing, and improve appearance and flavor stability. […] The post Everyday Food Additives Co…

The supplement is a proven sports performance enhancer, but research is ongoing and for most people it’s an optional extra, not an essential Once the preserve of bodybuilders and sprinters, creatine is now being touted as everything from a brain booster to a healthy-ageing essential. But should we all be taking it? Not quite. “There’s really substantial evidence of creatine being effective,” says…

Published on May 25, 2026 5:22 AM GMT TL;DR GiveWell has published a podcast, looking back on their investments in iron fortification and their $8.2M grant to Fortify Health in 2021. When the grant was made, the projected cost-effectiveness was 5x cash transfers we delivered and estimated 12x. We want to share what this looked like from the inside. Over three years, our team scaled from reaching …

Drinking nitrate-rich beetroot juice may do more than support heart health — it could actually reshape the bacteria living in the mouth in ways that help lower blood pressure in older adults. In the largest study of its kind, researchers found that older people who drank concentrated beetroot juice twice daily for two weeks experienced noticeable blood pressure reductions, while younger adults di…

HRV is only useful if it changes your day I have tracked HRV every morning for a few years now. Not because I like graphs. Because it is the only number that consistently talks back when I am lying to myself. I build web stuff, coach baseball, and play the biohacker hobby game. That combination makes it very easy to run on willpower and caffeine until something breaks. HRV is my early warning sys…

Food insecurity among adults in Tasmania was strongly associated with lower diet satisfaction and poorer self-rated mental and physical health, with diet dissatisfaction showing the strongest link. The findings suggest that food insecurity limits not only nutrition, but also food choice, agency, wellbeing, and equitable access to acceptable, affordable, and culturally appropriate diets.

A long-running study suggests that one of the simplest ways to support healthy aging may also be one of the most effective: eating slightly fewer calories. Search online, and you will find countless biohacking trends that promise healthier aging, from cold plunges and hyperbaric oxygen therapy to sleeping under red lights. But research from Tufts [...]

The 2026 CDC Nutrition Report will make nearly 24 years of NHANES biomarker data easier to use, covering up to 131 nutritional biomarkers in the US population aged 1 year and older. By standardizing blood and urine biomarker trends, demographic patterns, and comparisons of supplement use, the report aims to support nutrition policy, clinical reference intervals, and public health monitoring.

New research suggests grapes may offer surprising benefits for skin health by changing how genes behave in the body. Earlier clinical trials showed that eating grapes could improve resistance to UV radiation in about 30% to 50% of people. Now, scientists say the effects appear to be much broader and may influence nearly everyone in [...]

The review finds that several candidate biomarkers may help estimate fruit and vegetable intake more objectively than self-reported dietary tools, but most remain limited by specificity, sampling burden, supplement use, or incomplete validation. Blood and skin carotenoids appear strongest for habitual intake, while vitamin C, folate, urinary flavonoids, hippuric acid, and potassium may be more us…

GLP-1 agonists have been a remarkable treatment for those who suffer from obesity-related illness, but suppressing hunger cues could pose a risk for those with eating disorders.

Scientists are uncovering why some dietary fats may worsen metabolic disease while others appear to help protect against it. A new study is shedding light on how two common dietary fats may influence the risk of developing type 2 diabetes, a disease linked to serious health complications worldwide. The research, published in Trends in Endocrinology [...]
