Non-sugar sweeteners are neither miracle cures for obesity nor hidden health threats. Recent evidence shows they can modestly support weight loss, help reduce sugar intake and fit safely into a balanced diet.

The "uncomfortable truth" is clear: these sweeteners are context-dependent tools, not standalone solutions. Over-relying on them or ignoring overall eating patterns won't deliver big results. Let's take a closer look.

In a strange turn of events, The Lancet—one of the world's oldest medical journals—has taken a line you might expect to hear from Robert F. Kennedy Jr., declaring "ultra-processed" food a driver of chronic disease. Is there any evidence behind this association, or are we just dealing with academic snobs who can't appreciate the benefits of convenient, abundant food?

With highly potent and (sometimes) legal marijuana widely available across the US, emergency rooms are reporting an increase in cannabis hyperemesis syndrome (CHS), an unpleasant condition characterized by screaming and vomiting—"scromiting" in the vernacular. The condition is yet more evidence that marijuana’s reputation as a low-risk drug is undeserved.

What does science tell us about gluten sensitivity? Depending on whom you ask, it's either a heal scare advanced by social media grifters or a legitimate medical condition that afflicts many people. Let's take a closer look to separate fact from myth.

The story everyone knows about the opioid epidemic goes like this: Big, bad Purdue Pharma aggressively marketed its potent painkiller OxyContin, hooking legions of unsuspecting Americans on the pharmaceutical equivalent of heroin. It's a compelling tale—and it's wrong in almost of its particulars. Let's take a closer look.

In the high-stakes arena of cancer drug development, SU212 was engineered as a safer twist on podophyllotoxin—a toxic killer designed to halt rogue cell division. Yet in a twist worthy of scientific serendipity, it veered off course, bypassing its intended target entirely and stumbling upon a superior mark. SU212 starves aggressive cancers, slashing growth with scant harm to healthy cells. This off-script pivot echoes drug history's happy accidents. Let's talk about how luck can lead to scientific breakthroughs.

Following the emergence of COVID-19, "follow the science" became a stark ideological divide that pitted one American against another. This partisan framing weaponized the scientific method instead of letting it solve a critical public-health crisis. Is it time to abandon this unhelpful slogan and rethink our broken understanding of science?

"You have cancer." It's a life-changing (and sometimes life-ending) development—a horrible piece of news no one is really ever prepared to receive. Are there better and worse ways to react? Can you do anything to improve your prognosis? Dr. Chuck Dinerstein answers these questions while recounting his harrowing experience with prostate cancer.

Social media is awash in testimonials from anonymous men who claim that testosterone-replacement therapy (TRT) helped them beat depression, sexual dysfunction, obesity and other maladies that often impact men as they age. Such compelling endorsements no doubt appeal to others who struggle with these critical health issues, but do they stand up to scientific scrutiny? Let's take a closer look.

Experiencing heartburn? Then consuming an acidic product like apple cider vinegar isn't the solution. The logic is simple: if you've got excess stomach acid, more acid won't help. But up is down in the world of alternative medicine, so let's take a closer look at the bad chemistry behind this "natural" treatment for acid reflux.
