Ultra-processed foods now account for more than half of caloric intake in the average American diet, and a growing body of research links them to cancer, cardiovascular disease, metabolic disorders, and declining mental health. Understanding what ultra-processed foods are — and why they appear to cause harm beyond their individual ingredients — is foundational health literacy in 2026.

Most men only see a doctor when something already hurts. Preventive men's health screenings exist precisely to find problems before symptoms appear — catching cardiovascular disease, cancers, and metabolic disorders at stages when treatment is most effective. This guide covers which tests men actually need at every age, based on current clinical guidelines.

Researchers have identified lifestyle habits, biological mechanisms, and environmental factors that consistently predict longer, healthier lives. Understanding what separates lifespan from healthspan — and what the latest anti-aging research actually supports — may be the most important health education you undertake this year.

GLP-1 (glucagon-like peptide-1) is a hormone your gut releases after you eat. It tells the pancreas to release insulin, lowers blood sugar, slows how fast your stomach empties, and signals your brain that you are full. Ozempic (semaglutide) is a synthetic copy of this hormone, called a GLP-1 receptor agonist, that lasts far longer in the body than the natural version. That is why one weekly injection can manage blood sugar and reduce appetite. How does GLP-1 work? GLP-1 binds

Inflammation is your immune system's natural response to injury, infection, or harmful substances. Blood flow increases to the affected area, and white blood cells and signaling chemicals move in to remove the threat and start repair. Short-term (acute) inflammation protects you and usually settles on its own. When inflammation lasts for months or years, it becomes chronic and can begin to damage healthy tissue. What does inflammation do in your body? Inflammation is part of

Ozempic (semaglutide) is a GLP-1 receptor agonist approved to treat type 2 diabetes. Its most common side effects are digestive: nausea, diarrhea, vomiting, constipation, and stomach pain. Most side effects are mild and usually ease within a few weeks as your body adjusts to the dose. Rare but serious risks include pancreatitis, gallbladder problems, kidney injury, and a boxed warning for thyroid tumors. The rest of this page answers the questions patients ask most, separates

Key takeaways Trust in your doctor dropped from 93% to 85% between June 2023 and January 2025 (KFF). Trust remains high, but it is falling quickly. The decline traces to pandemic-era policy reversals, conflicting public guidance, and growing scrutiny of the pharmaceutical industry. Lower trust has real costs: delayed care, refused treatments, and greater vulnerability to health misinformation. Healthy skepticism and harmful distrust are not the same thing—one protects you, th

Walk into any grocery store today, and you’ll see kombucha advertised as a gut health solution, turmeric products promising to fight inflammation, and blueberry packaging suggesting cognitive protection. Scan your social media feed, and you’ll see claims that some foods can reverse autoimmune disease, wipe out cancer risk, or cure chronic diseases that doctors struggle to treat with pharmaceuticals. Meanwhile, hospital systems are launching “food as medicine” initiatives. Ins

Americans are turning to artificial intelligence more frequently for health advice. Pew Research’s 2026 findings show that some 38% of Americans now use AI tools weekly to inquire about symptoms, medications, diagnoses, and treatment options. This isn’t fringe behavior. It’s a mainstream shift in how people get health information. The question to be asked is not whether AI is being used for health questions. It surely is. The real question is, is AI reliable for health inform
