Walk down any grocery aisle and the words on the labels almost write themselves. Zero sugar. No calories. Keto-friendly. Diet. For decades, the assumption built into all of that marketing has been that swapping out sugar for a sweetener was a free trade, with the calories gone and nothing meaningful taken on in their place. The newer research is starting to complicate that picture. A Medscape review in late May pulled together a body of evidence that has been building for the

If you've ever been told you have prehypertension or stage 1 hypertension, you probably know the feeling that follows. The numbers aren't quite bad enough to start medication. They aren't quite good enough to ignore. You leave the appointment with a vague directive to lose some weight, walk more, eat less salt, and recheck in three months. For a lot of people, that middle zone is where blood pressure drifts in the wrong direction. A small trial out of the United Kingdom, just

Ashwagandha has had a long run as one of the most widely used adaptogenic herbs in the wellness world. Capsules, gummies, sleep blends, energy drinks, latte powders. If you've spent any time in a supplement aisle in the last decade, you've seen it. On April 16, 2026, the Indian Food Safety and Standards Authority issued an advisory that reshaped the global ashwagandha conversation: it banned the use of ashwagandha leaves, in any form, in Indian food and supplement products. T

Cocaine addiction has been one of the most stubborn problems in addiction medicine. Despite decades of research and considerable money spent, no medication has ever been approved for cocaine use disorder. Use is rising in the United States and globally. Most people who want to stop are offered cognitive behavioral therapy and contingency-management approaches, both of which help, neither of which works as reliably as patients and clinicians wish. A trial published this month

Most people who want to drink less alcohol already know they want to. The harder question is what actually moves the needle. Resolutions made on January 1 fade. Vague intentions to "cut back" rarely survive a stressful Tuesday. A randomized controlled trial published in Addictive Behaviors in 2021, recirculated this month in ScienceAlert, tested several public-health messages against each other and found one combination that worked when others didn't. The result is worth paus

There's a particular flavor of anxiety that shows up after meals. Not the dramatic, panic-attack version. The lower-key one: a little jittery, a little wired, a little harder to settle than you should be for the time of day. Some people have been living with that pattern for years and chalking it up to stress, caffeine, or a busy mind. A new study out of France adds a different possible piece to the picture. For a meaningful slice of the population, the body simply isn't abso

If you have COPD, you already know the daily picture. Some mornings the cough is louder than it was the night before. Some afternoons a flight of stairs feels longer than it used to. Most clinical conversations turn on inhalers, exacerbation prevention, and getting through the next winter without a hospital visit. Diet usually gets a passing mention. A small new study out of Johns Hopkins makes a case that one specific piece of the diet, the isoflavones in soy and other legum

Most research on how the gut talks to the brain has, until now, centered on chemistry: bacteria producing signaling molecules, immune cells responding, metabolites circulating. A March 2026 paper in PLOS Biology added a finding that sounds almost too literal to be plausible. In mice, when the gut becomes leaky, actual bacteria physically travel from the intestine, along the vagus nerve, and into the brain. TL;DR: A mouse study just showed bacteria physically traveling from a

A patient comes in with a familiar story. Years of bloating, intermittent diarrhea, vague abdominal discomfort after meals, weight that won't quite stay on. She has been told it's IBS. She has been told it's stress. She has been told to try a low-FODMAP diet, which helped a little but not as much as she expected. The piece that hasn't been checked, in some of these patients, is whether the pancreas is keeping up with the work of digestion. A practitioner-focused review by Chr

The story of gut bacteria and mood has been building for fifteen years. Patients with depression have measurably different microbial communities. Animal studies show that transplanting gut microbes from depressed humans into germ-free mice produces depressive behaviors in the mice. The mechanisms have been blurry, though. Researchers have been pointing at inflammation, vagal signaling, neurotransmitter precursors, yet no one has been able to point at a specific molecule the b

TL;DR: A new study mapped 31 pesticides against Peru's cancer registry, and the geography lined up — with liver tissue pointing at a non-genotoxic mechanism, not direct DNA damage. Photo: Shelley Pauls / Unsplash Key takeaways: 31 pesticides mapped against Peru's cancer registry — the geographic overlap is striking. Hotspot livers showed a gene-expression signature pointing at non-genotoxic disruption. Single-chemical studies miss what mixed real-world exposure looks like. Pr

TL;DR: A new observational study suggests late-night eating only damages gut function when stacked on top of chronic stress. Eating timing alone isn't doing the harm. KEY TAKEAWAYS: High stress PLUS late-night eating: abnormal bowel habits 39.3% vs. 23.2% baseline Late night eating alone, without high stress, wasn't linked to worse gut function The compounding stressors framework explains gut symptoms that "just don't eat late" misses Sleep, work, mood, or environment: whic

A new paper found that Methanobrevibacter smithii, a common gut archaeon, shows up more often in people with colorectal cancer and appears to cooperate metabolically with cancer-linked bacteria — but the evidence-supported levers for lowering risk are still fiber, plant diversity, and age-appropriate screening.

If you have ever been told you have polycystic ovary syndrome, there is a decent chance you walked out of that appointment confused. Maybe an ultrasound was normal. Maybe there were no actual cysts. Maybe you were told you had PCOS because of irregular cycles and acne and weight that wouldn't budge, and you spent the next decade trying to find a clinician who understood why the name and the lived experience didn't line up. A May 2026 paper in The Lancet finally calls the ques

Have you spent any time in the longevity corner of the internet? You've heard about rapamycin. Originally an immunosuppressant given to organ transplant patients, this drug has become the darling of the geroscience world because it extends lifespan in mice, slows certain markers of cellular aging in lab studies, and gets a lot of biohacker airtime as a potential anti-aging tool in humans. A new randomised, double-blind, placebo-controlled trial, RAPA-EX-01, just complicated t

A patient called the office last winter to ask whether the weight-loss injection she was buying online was the same as the one her cousin was getting through her insurance. The price was a third of what her cousin was paying. The vials looked similar. The website mentioned a "compounding pharmacy partner." She wanted to know if she should be worried. The answer, in a phrase, is yes. A new study presented this April at the Obesity Medicine Association 2026 meeting put hard num

There's a particular moment most of us have witnessed in someone we love. A grandparent pushing off the arms of a chair to stand. The pause. The slight wobble. The small, half-conscious calculation of whether to try a second time or sit back down. That moment is what researchers call "lower-limb power," and when it slips, fall risk rises. A six-month randomised controlled trial out of Deakin University in Australia, published in February 2026 in the Journal of Cachexia, Sarco

A study getting headlines this month showed that a seed extract from the moringa tree can remove microplastics from drinking water, in some conditions as effectively as the chemical coagulants currently used in water treatment plants. The headline is fun. The deeper story is more important. Microplastics are a real and growing exposure, and personal water filtration is one piece of a much larger conversation about the chemicals we're all swimming in. What the research found A

A small randomized trial out of Turkey is making the rounds for showing that inhaled thyme essential oil eased a long list of COVID-19 symptoms in hospitalized patients. The naturopathic instinct on a story like this is to nod and say "yes, of course, plants have been in the lungs game for centuries." The scientifically rigorous instinct is to slow down, look at the trial design, and ask what the data actually support. Both can be true. Let's hold both. What the research foun

Have you (or someone close to you) been on a GLP-1? You already know the nausea conversation. It's the most common side effect, the most common reason people stop the medication, and the thing that makes the first few weeks of dosing harder than the medication itself. A new pilot trial reported by Medscape in April 2026 asked whether something as simple as a ginger supplement could take the edge off. The signal is small, the trial is small, the data is preliminary in every wa
