Myth: delaying the birth-dose hepatitis B vaccine is harmless. Modeling suggests replacing universal newborn vaccination with delayed or shared-decision approaches could substantially increase chronic hepatitis B infections in children.
Take: Follow the local newborn hepatitis B schedule and don't postpone on your own; ask your pediatric or vaccination clinic if unsure.
Myth: ADHD is just a trend or bad parenting. Scientists debunk this and similar claims; ADHD is a recognized condition with neurobiological underpinnings that can be diagnosed and managed.
Take: Avoid labeling yourself or a child as lazy or disobedient; if attention, impulsivity, or organization problems interfere with daily life, seek a professional evaluation.
Myth: trendy diet beliefs are all backed by research. A 2026 review tested popular diet claims and found several were not supported by the evidence.
Take: Be skeptical of absolute rules like "always eat on an empty stomach" or "never combine these foods"; focus on overall diet patterns and reliable sources.
Myth: only 10,000 daily steps help the brain. New research links about 3,000 steps a day to slower Alzheimer's-related brain changes and less cognitive decline, even in people with early signs.
Take: Don't be intimidated by 10,000; start with a short daily walk and split it into a few bouts you can sustain.
Myth: red meat's link to diabetes is only about weight gain. In nearly 90,000 adults, those consuming the most of a little-known sugar in red meat had a 63% higher type 2 diabetes risk, possibly via chronic inflammation.
Take: You don't have to quit red meat, but swap some for beans, fish, or poultry; watch portion size and frequency rather than eating it at every meal.
Myth: excess salt only affects blood pressure. Animal research suggests a high-salt diet may also harm memory and social behavior, while a soy-derived compound called LPC70 showed protective effects in mice.
Take: Look beyond the blood pressure cuff: cut back on salt and soy sauce in cooking and go easy on salty processed foods; use spices and vinegar for flavor and reduce salt gradually.
Myth: sleep problems in Alzheimer's just have to be endured. In mice, sleep loss was traced to overactive brain immune cells; temporarily removing them restored more than two hours of sleep a day.
Take: This isn't a cue to self-medicate; tell your doctor about persistent poor sleep, keep regular hours, and stay active during the day instead of silently toughing it out.
Myth: if taste is still off more than a year after COVID, nothing can be done. Researchers examining taste buds found molecular abnormalities that weaken taste signals, offering clues to explain and address the symptom.
Take: Don't dismiss it as "all in your head"; report persistent taste problems to an ENT or post-COVID clinic, and keep meals balanced rather than over-salting or over-sugaring to compensate.
Myth: carrying a high-risk Alzheimer's gene means you're doomed. Scientists found a rare protective mutation that helps some high-risk people stay sharp into their 80s by limiting harmful protein buildup.
Take: Genes aren't a verdict, so don't give up on brain-protective habits; staying active, managing blood pressure and blood sugar, and socializing still matter for your brain.
Myth: fatty liver is a single condition. Mayo Clinic researchers found it actually consists of five biological subtypes, each with different risks such as liver failure, in a disease affecting nearly 30% of adults worldwide.
Take: If diagnosed, don't just "cut fat"; get metabolic and liver assessments as advised, manage weight, and keep regular follow-ups instead of treating it as one-size-fits-all.
