Health
Individual health, treatments, and medical claims.
A Beef-Only Diet Cures Autoimmune and Psychiatric Conditions
FalseMikhaila Peterson claims that a diet consisting exclusively of beef, salt, and water cured her juvenile rheumatoid arthritis, severe depression, and a range of other conditions. These claims are anecdotal and unsupported by clinical trials. Doctors warn of serious nutritional deficiencies.
Aaron Rodgers Was 'Immunised' Against COVID Without a Vaccine
FalseAaron Rodgers told the NFL and the media he was 'immunised', implying he was vaccinated, and then tested positive for COVID one week into the season. It emerged that he had been following an alternative protocol developed in consultation with Robert Malone. No alternative immunisation protocol is clinically equivalent to a vaccine.
Alkaline water cures disease and balances body pH
FalseAlkaline water, marketed as a cure or preventive treatment for cancer and other diseases by raising the body's pH, has no clinical evidence supporting these claims, and human physiology already tightly regulates blood pH regardless of what is consumed.
Antibiotics can treat viral infections
FalseAntibiotics are designed to target structures and processes specific to bacteria and have no effect on viruses, which replicate using entirely different mechanisms; taking antibiotics for viral infections such as colds or flu provides no benefit and contributes to antibiotic resistance.
Apple cider vinegar cures many illnesses
FalseApple cider vinegar has some limited, modest evidence for minor effects on blood sugar and appetite, but claims that it cures cancer, controls blood pressure, or works as a general health tonic are not supported by science. A widely cited 2024 weight-loss study on the topic was later retracted.
Baking soda cures cancer
FalseThe claim that ingesting sodium bicarbonate can cure cancer by "alkalizing" the body has no support in clinical evidence. Human blood pH is tightly regulated within a narrow range regardless of diet, and no trial has shown baking soda cures or shrinks tumors in humans.
Bluetooth radiation is dangerous to health
FalseBluetooth devices emit non-ionizing radiofrequency radiation at power levels far below international safety limits, and the large body of research on radiofrequency exposure has not established that Bluetooth use causes cancer or other significant health harm.
Breakfast is the most important meal of the day
MixedThe claim that breakfast is uniquely essential for health and weight management is not well supported by rigorous controlled trials, which generally find no significant metabolic advantage to eating breakfast specifically, though breakfast can be a practical and beneficial meal for some individuals depending on personal schedule and health status.
Cell phones cause brain cancer
MixedMost large epidemiological studies and national cancer registry data show no consistent increase in brain tumor rates corresponding to the rise in mobile phone use. IARC classifies RF radiation as "possibly carcinogenic" (Group 2B) based on limited evidence, prompting continued research and precautionary guidance.
Certain foods significantly boost your metabolism
FalseFoods commonly marketed as metabolism boosters, including chili peppers, green tea, and coffee, produce only small, short-lived increases in calorie burning that are far too modest to meaningfully affect weight, contradicting marketing claims that specific foods can significantly accelerate metabolism.
Chocolate causes acne
MixedThe relationship between chocolate and acne has been debated for over half a century. An influential 1969 study found no link and was long treated as definitive, but more recent, better-designed trials have found that chocolate consumption may increase acne lesions in some people, possibly through glycemic or inflammatory mechanisms rather than a unique property of chocolate itself.
Cold weather itself makes you catch a cold
FalseColds are caused by viral infection, not by cold temperature exposure itself, though cold weather is associated with behavioral and biological factors that genuinely increase transmission, which explains the seasonal pattern without cold air itself being the direct cause.
Collagen supplements firm your skin
MixedSome randomized controlled trials report modest improvements in skin elasticity, hydration, and wrinkle depth with hydrolyzed collagen supplements, but a 2025 meta-analysis found that when industry-funded studies are excluded and only high-quality independent trials are analyzed, the measured benefits disappear, leaving the overall evidence inconclusive.
Colon cleanses remove toxic buildup from the intestines
FalseColon cleansing products and procedures, marketed to remove accumulated toxic waste from the intestines, are based on an inaccurate model of digestive anatomy, and gastroenterologists find no evidence that healthy colons accumulate the toxic buildup these products claim to remove.
Cracking your knuckles causes arthritis
FalseThe common belief that habitually cracking knuckles causes arthritis has been tested in multiple studies, including a decades-long self-experiment by a physician, and none have found a meaningful association between knuckle cracking and arthritis development.
Deodorant and antiperspirant cause breast cancer
FalseMajor cancer research organizations, including the American Cancer Society and National Cancer Institute, find no consistent scientific evidence that antiperspirants or deodorants, including those containing aluminum compounds, increase breast cancer risk.
Detox diets remove toxins from the body
FalseCommercial detox diets claiming to flush toxins from the body through juice cleanses, restrictive fasting, or special supplements have no clinical evidence supporting their claimed mechanism, since the liver and kidneys already continuously perform this function in healthy people.
Detox foot pads remove toxins through the feet
FalseAdhesive detox foot pads, marketed to draw toxins out of the body overnight through the soles of the feet, have no clinical evidence supporting their claimed mechanism, and the dark residue they produce after use has been shown in testing to result from the pads' own ingredients reacting with moisture and heat, not from extracted toxins.
Detox juice cleanses remove toxins
FalseNo scientific evidence supports the claim that juice cleanses remove toxins from the body. The liver and kidneys already perform this function continuously and effectively in healthy people. Juice cleanses can cause nutrient deficiencies, blood sugar spikes, and in some cases kidney harm.
Double-dipping a chip into shared dip spreads significant amounts of bacteria
MixedA controlled study measuring bacterial transfer from double-dipping found it does measurably increase the number of bacteria in shared dip compared to no double-dipping, though the studied increase was modest and the same research found dip consistency and acidity affect bacterial survival more than the double-dipping act itself.
Ear candling removes earwax and toxins
FalseEar candling, which involves burning a hollow cone-shaped candle near the ear canal, does not remove earwax or toxins, and the residue left behind after the procedure has been shown to come from the candle itself; the practice also carries a documented risk of burns and injury.
Eating late at night causes weight gain regardless of total calories
MixedResearch on meal timing and weight gain finds that total daily calorie intake remains the primary driver of weight change, though some studies suggest late-night eating is associated with poorer food choices, disrupted metabolism, and reduced sleep quality that can indirectly contribute to weight gain over time.
Eating sugar causes a rush of energy and hyperactivity
MixedBlood sugar does rise after eating sugary food, producing a real but modest and brief increase in available energy, but controlled studies have not found that sugar intake causes the dramatic hyperactivity or subsequent 'crash' commonly described as a sugar rush, particularly in children, an idea more strongly shaped by expectation than by direct causation.
Food dropped on the floor is safe to eat if picked up within five seconds
FalseControlled laboratory testing finds that bacteria can transfer to food essentially immediately upon contact with a contaminated surface, meaning contact time within the range of a few seconds makes little meaningful difference to contamination risk, contradicting the popular five-second rule.
Hair growth vitamins and supplements work for everyone
MixedHair growth supplements, commonly containing biotin and other vitamins, can meaningfully help hair growth in people with an actual underlying nutrient deficiency, but there is limited evidence they provide any additional benefit for people who are already adequately nourished, despite broad marketing claims suggesting universal benefit.
Homeopathy can treat cancer
FalseNo credible clinical evidence supports homeopathy as an effective cancer treatment. Homeopathic preparations are typically diluted to the point of containing no detectable active ingredient. Relying on homeopathy instead of conventional treatment has been associated with substantially worse survival outcomes.
Lactic acid buildup causes muscle soreness after exercise
FalseLactic acid, more precisely lactate, is cleared from muscles within about an hour after exercise ends, and delayed onset muscle soreness that appears one to three days later is caused by microscopic muscle fiber damage and inflammation, not by lingering lactate.
Megadosing vitamins improves health
FalseThe idea that taking vitamin doses far above established recommendations improves health is not supported by evidence and carries documented risks. Fat-soluble vitamins accumulate in body tissue and can reach toxic levels, and megadosing several water-soluble vitamins has also been linked to serious, sometimes irreversible, adverse effects.
Microchips in vaccines
FalseCOVID-19 vaccines do not contain microchips, RFID trackers, or any tracking technology. Independent elemental analysis of vaccine vials and public regulatory disclosure of all ingredients confirm no electronic components exist. The claim originated from a misinterpretation of Bill Gates' remarks about digital health records.
Miracle Mineral Solution (MMS) cures disease
FalseMiracle Mineral Solution, an industrial bleach solution containing chlorine dioxide marketed as a cure for autism, cancer, HIV, and many other conditions, has no clinical evidence supporting its efficacy and has caused documented cases of severe injury and death, prompting explicit warnings from health regulators worldwide.
Moderate drinking kills brain cells
MixedAlcohol does not directly kill neurons at the doses associated with moderate or even heavy social drinking. It does disrupt neuronal function, inhibits dendrite growth, and at high chronic doses over years produces documented structural brain changes. The claim as commonly stated is false, but alcohol is not harmless to the brain either.
Muscle turns into fat when you stop exercising
FalseMuscle and fat are biologically distinct tissue types that cannot convert into one another; when exercise stops, muscle tissue can shrink through atrophy while fat tissue can independently increase due to reduced calorie expenditure, but no biological process transforms one tissue type into the other.
Natural immunity is always better than vaccine immunity
MixedFor some diseases, infection-acquired immunity can be similar to or longer-lasting than vaccine immunity, but this comes at the cost of the disease itself, which carries real risks of severe illness, complications, and death that vaccines are specifically designed to avoid.
No pain, no gain, exercise must hurt to be effective
FalseEffective exercise does not require pain, and sports medicine research distinguishes between the normal, mild discomfort of muscular effort and delayed onset muscle soreness, both of which are unrelated to actual injury pain, which is a warning signal that should prompt reduced activity rather than being pushed through.
Raw untreated water is healthier
FalseRaw water, untreated water sold or collected without filtration or disinfection, carries a documented risk of pathogens and contaminants that water treatment specifically exists to remove. There is no scientific evidence that untreated water offers health benefits that outweigh these risks, and public health authorities uniformly recommend treated or otherwise verified safe drinking water.
Reading in dim light permanently damages your eyes
FalseReading in dim light can cause temporary eye strain and fatigue, but ophthalmologists find no evidence that it causes any permanent structural damage to the eyes or lasting vision loss.
Shaving makes hair grow back thicker and darker
FalseShaving cuts hair at the surface of the skin without affecting the hair follicle beneath, and controlled studies find no change in the actual thickness, color, or growth rate of hair as a result of shaving; the appearance of coarser regrowth is a visual and tactile illusion.
Sitting too close to the TV damages your eyes
FalseSitting close to a television does not cause permanent eye damage; the belief traces largely to older cathode-ray tube sets that emitted small amounts of radiation later corrected by regulation, and modern ophthalmology finds no lasting harm from close viewing distance itself, though it may indicate an existing vision problem.
Stretching before exercise prevents injury
MixedResearch on stretching and injury prevention finds that static stretching before exercise does not reliably reduce injury risk and may modestly impair immediate strength and power output, while a proper dynamic warm-up shows more consistent evidence for reducing injury and improving performance.
Sugar makes children hyperactive
FalseThe widely held belief that sugar consumption directly causes hyperactive behavior in children has been tested in numerous controlled trials, which consistently fail to find a causal link, suggesting the perceived connection is largely driven by parental expectation and the social context in which sugary foods are typically consumed.
Swallowed gum stays for 7 years
FalseThe claim that swallowed chewing gum remains in the stomach for seven years has no scientific basis. The digestive system moves indigestible gum base through the gastrointestinal tract at roughly the same pace as other food, typically within 24 to 48 hours, and it exits the body in stool like anything else that cannot be broken down.
Sweating removes toxins from the body
FalseSweat is primarily composed of water, sodium, and other electrolytes released for the purpose of body temperature regulation, and while sweat does contain trace amounts of some other compounds, research finds sweating is not a meaningful mechanism for eliminating toxins compared to the liver and kidneys.
Teething causes high fever
FalseTeething can cause a slight rise in body temperature, irritability, and drooling, but it does not cause a true fever of 38 degrees Celsius (100.4 Fahrenheit) or higher. Any fever reaching that threshold in an infant reflects illness, not teething, and needs medical evaluation.
The alkaline diet changes your blood pH
FalseThe alkaline diet claims that eating specific foods can change the body's blood pH to prevent disease and improve health, but human blood pH is tightly regulated within a very narrow range by the lungs and kidneys regardless of diet, and no rigorous clinical evidence supports the diet's disease-prevention claims through this proposed mechanism.
The Carnivore Diet Cures Depression and Autoimmune Diseases
FalseJordan Peterson and his daughter Mikhaila Peterson claim that a diet consisting exclusively of beef, water, and salt - the so-called 'Lion Diet' - cured their depression, anxiety, and autoimmune conditions. No clinical trials support these claims, and nutritionists warn of serious health risks.
Trump said "Nothing bad can happen, it can only good happen"
FalseIn September 2025, Trump said "nothing bad can happen, it can only good happen" while promoting an unproven Tylenol–autism link at a White House press event. The phrase went viral as a word salad, but the more serious issue was the medically misleading advice to pregnant women.
Vaccines and autism
FalseDecades of large-scale epidemiological research across multiple countries have found no causal link between vaccines and autism spectrum disorder. The original 1998 study that sparked the controversy was retracted after being exposed as deliberate scientific fraud.
Vaccines cause infertility
FalseNo scientific evidence links any vaccine, including COVID-19 vaccines, to infertility in men or women. Multiple large prospective studies, systematic reviews, and major reproductive medicine organizations have investigated this specific claim directly and found no supporting evidence.
Vaccines cause SIDS
FalseVaccines do not cause Sudden Infant Death Syndrome. Large epidemiological studies comparing vaccinated and unvaccinated infants find no increased SIDS risk from vaccination, and SIDS rates have declined substantially since the 1990s even as childhood vaccination schedules expanded, a pattern inconsistent with vaccines causing SIDS.
Vaccines overwhelm the immune system
FalseThe childhood vaccine schedule uses a tiny fraction of the immune system's capacity. Infants encounter and successfully respond to thousands of new antigens daily through ordinary environmental exposure, far exceeding the antigen load from the entire recommended vaccine schedule combined.
Vaping is completely harmless
FalseVaping is not harmless. E-cigarettes expose users to nicotine, ultrafine particles, and toxic chemicals, and have been linked to lung disease, cardiovascular strain, and nicotine addiction, particularly among youth. Current evidence suggests vaping is likely less harmful than combustible cigarettes for established adult smokers who switch completely, but that comparative claim is very different from vaping being safe.
Vegetables and Fruit Are Toxic and Should Be Avoided
FalsePaul Saladino, known as the 'carnivore doctor', claims that plant foods contain toxins and antinutrients that seriously harm human health and should be eliminated from the diet. Decades of nutritional epidemiology show the opposite: high consumption of vegetables and fruit is consistently associated with lower risk of cardiovascular disease, cancer, and all-cause mortality.
Vitamin C megadoses cure colds and cancer
FalseHigh-dose vitamin C is widely promoted as a cure for the common cold and cancer, but rigorous clinical trials have found it does not prevent colds in the general population, shortens cold duration only marginally, and has not been shown to cure cancer.
Wi-Fi harms the brain
MixedWi-Fi routers emit low-power, non-ionizing radiofrequency radiation at levels far below international safety limits. No established scientific evidence links typical Wi-Fi exposure to brain harm, cancer, or the symptoms described in "electromagnetic hypersensitivity."
You can target fat loss in specific body areas through exercise
FalseThe idea that exercising a specific body part, such as doing abdominal crunches to lose belly fat, burns fat preferentially from that area is not supported by controlled research, which consistently finds that fat loss occurs across the body according to genetic and hormonal patterns rather than the specific muscles being exercised.
You must drink 8 glasses of water a day
MixedThe specific recommendation to drink exactly eight 8-ounce glasses of water daily has no clear scientific origin and does not match current hydration guidance, which recognizes that fluid needs vary by individual and can be met partly through food and other beverages, not just plain water.
