249 articlesAre vapor inhalers safe? The short answer is that no inhaled vapor device is risk-free, but harm depends heavily on what is being vaporized: nicotine e-liquids are widely judged substantially less harmful than combustible cigarettes for…
Let's find outYes, Trojan condoms are good. They are reliable, widely tested, and regulated as medical devices under FDA rules that cap the allowable breakage rate at 0.4% during water leak testing.
Let's find outAre tonsil stones a symptom of something serious? In the overwhelming majority of cases, no.
Let's find outNo vaccine is approved to prevent or cure multiple myeloma. The FDA has licensed no preventive or therapeutic myeloma vaccine as of November 2026.
Let's find outAre thermogenic fat burners safe? Not entirely. Most are safe for healthy adults at label doses, but the category has real cardiovascular and liver risks concentrated in stimulant-heavy and proprietary-blend products.
Let's find outYes, there are ticks in Ireland, and at least six species have been recorded there. The sheep tick (Ixodes ricinus) is the common biting species, and it is present across most of the country, including urban parks and domestic gardens.
Let's find outYes, there are genuinely different types of gluten, but not in the way most people assume. "Gluten" is not a single molecule but a family of related storage proteins, and different grains carry structurally distinct versions.
Let's find outYes, several natural compounds can nudge the same metabolic levers tirzepatide pulls, but none matches its effect size. Tirzepatide, a dual GIP/GLP-1 receptor agonist, produces roughly 15 to 21 percent body-weight loss in trials.
Let's find outNo. Tobacco and weed (cannabis) are not the same, even though both are smoked plant material delivering psychoactive drugs through the lungs.
Let's find outYes, tinnitus and vertigo are related, but not in a one-to-one way: they are sibling symptoms that often arise from the same inner-ear and vestibular-nerve pathology rather than from each other.
Let's find outNo, the scientific consensus is that milk from rBST-treated cows is not measurably different in safety from other milk, and no major health authority has found a health risk from drinking it.
Let's find outYes, there are mosquitoes in the UK, and they are a genuine but limited public health risk. Around 34 native mosquito species breed across Britain, and the widespread Culex pipiens complex is the country's most common biting mosquito.
Let's find outNo, there are no muscles in your fingers. The fingers contain only bones, joints, tendons, ligaments, blood vessels, and skin.
Let's find outYes, there are different types of hazel eyes. Hazel is not one color but a continuum, and clinicians and color analysts commonly sort it into five subtypes: classic golden hazel, green-dominant hazel, brown-dominant hazel, gray-hazel, and…
Let's find outYes, lymph nodes sit under and around the breast, but they are not buried inside the fatty tissue itself. The nodes people feel as "under the breast" belong to the axillary (armpit) and infraclavicular (below the collarbone) groups.
Let's find outYes, measurable average differences in the corpus callosum exist between males and females, but they are small, overlap heavily between the sexes, and most claims about what they mean are unsupported.
Let's find outNo, there are no lymph nodes on your ribs themselves. Ribs are bone, and bone contains marrow but no lymph node tissue.
Let's find outYes, there are bones in your nose, but not in the part you can pinch.
Let's find outYes, there are different types of autism, but not in the way most people imagine.
Let's find outYes, sweet potatoes are good for most people with diabetes when eaten in controlled portions and prepared a certain way.
Let's find outYes, cannabinoids can be detected in human breast milk, and THC is the cannabinoid found most consistently.
Let's find outAre support groups helpful? Yes, for most people, but modestly and conditionally.
Let's find outYes, sweet potatoes are low-glycemic relative to white potatoes, but only under specific conditions: a boiled sweet potato has a glycemic index (GI) of roughly 44 to 50 and a glycemic load (GL) of about 11 per 150-gram serving, which…
Let's find outPoke berries are not safe to eat. The pokeweed plant (Phytolacca americana) contains cytotoxic saponins, mitogenic lectins, and oxalic acid, and every part of it is toxic to humans when raw, including the berries.
Let's find outSweet potato fries are healthier than regular French fries but not healthy in absolute terms.
Let's find outYes, tetraplegia and quadriplegia are the same condition. Both terms describe paralysis of all four limbs and the torso, and the word roots are equivalent: "tetra" is Greek for four, while "quadri" is Latin for four.
Let's find outAre tattoos self-harm? No — not by definition. Self-harm is deliberate self-inflicted injury used to regulate distress, and the clinical criteria require that function, not the wound itself.
Let's find outYes, strawberries and blueberries are good for you, and they are among the most nutrient-dense fruits you can eat.
Let's find outAre skin tag removers safe? For most people, yes, home and professional removal of skin tags (acrochordons) is low-risk, but safety depends entirely on correct diagnosis: benign skin tags rarely bleed, ulcerate, or change color, and…
Let's find outYes, scrambled eggs are good for pregnancy, provided they are cooked until both the white and yolk are fully firm and served hot.
Let's find outSteroids are not effective for treating typical RSV bronchiolitis in infants, and major guidelines recommend against their routine use.
Let's find outAre stress tests accurate for detecting heart disease? They are moderately accurate, not definitive.
Let's find outYes, canned sardines packed in olive oil are genuinely good for you for most adults, delivering roughly 20 to 25 grams of protein, 1.0 to 1.8 grams of omega-3 fatty acids, and 300 to 400 international units of vitamin D per 3.5-ounce…
Let's find outYes, sesame seeds are gluten free. Pure sesame seeds contain no gluten proteins because sesame is an oilseed, not a cereal grain, and gluten occurs only in wheat, barley, rye, and their hybrids.
Let's find outAre skin tags a true sign of diabetes? No — a skin tag (acrochordon) is not a diagnostic sign of diabetes.
Let's find outKidney stones are usually painful rather than dangerous, with most stones under 5 millimeters passing on their own without lasting harm.
Let's find outNo, schizoid personality disorder does not make a person dangerous.
Let's find outYes, SKYN condoms are latex free. Every condom in the SKYN line is made from polyisoprene, a synthetic polymer that contains no natural rubber latex proteins, so it is safe for people with latex allergy.
Let's find outYes, a yellow scab is usually supposed to be yellow. The yellow-tan color comes from dried serum, the clear fluid left behind after blood clots, mixed with fibrin and dead white blood cells.
Let's find outNo, schizophrenia and narcissistic personality disorder are separate conditions, and schizophrenia does not make a person narcissistic.
Let's find outAre Root Canals a Scam? No. A root canal is a legitimate dental procedure with a long track record, treating infection inside a tooth by removing damaged pulp, cleaning the canal system, and sealing it.
Let's find outYes, STDs are tested through urine, but only a specific subset: chlamydia, gonorrhea, trichomoniasis, and sometimes Mycoplasma genitalium are detectable on a urine nucleic acid amplification test (NAAT).
Let's find outYes — refrigerated probiotics are generally better than shelf-stable ones when live-cell delivery to the intestine is the goal, because cold storage slows the metabolic activity and moisture-driven degradation that reduce colony-forming…
Let's find outRingworm bald spots are usually reversible, not permanent. The fungus itself does not kill hair follicles; it invades the hair shaft and the skin around it, and hair typically regrows once effective antifungal treatment clears the…
Let's find outRice Crispy treats are not healthy in any meaningful nutritional sense — they are a near-pure carbohydrate food, delivering roughly 20 to 25 grams of sugar and 90 to 130 calories per 40-gram square with almost no protein, fiber, vitamins,…
Let's find outYes, refried beans are healthy for most people, with one major caveat: the canned version is often high in sodium, while the homemade version is not.
Let's find outYes, protein shakes are generally safe during pregnancy when they are used as a supplement to a balanced diet and not as a replacement for meals.
Let's find outYes, raisins are high in potassium. A standard quarter-cup serving (about 43 grams) delivers roughly 320 to 350 milligrams of potassium, which is more than 7 percent of the 4,700 mg daily target for adults.
