“Judaism prohibits smoking.”

Smoking is prohibited by the predominant contemporary interpretation of Jewish law because it poses a well-established danger to health and life. Major Orthodox, Conservative and Reform authorities support that conclusion. However, Judaism has no single central legal authority, and historical and continuing minority opinions prevent the prohibition from being described as universal.

“The American Psychiatric Association published the first edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM) in 1952.”

Historical records conclusively establish that the American Psychiatric Association published the first DSM edition in 1952. The original publication and independent scholarly histories confirm both the publisher and date. Earlier psychiatric classification manuals were precursors, not earlier editions of the DSM.

“Sex hormone levels are associated with crime victimization rates.”

Available research does not substantiate a general association between sex hormone levels and crime victimization rates. Some studies connect victimization with subsequent hormonal changes or examine hormones in trauma responses, providing a narrow biological link. However, the strongest victim-focused evidence mainly concerns cortisol, a stress hormone, while testosterone research largely concerns offending or aggression. No cited study shows that baseline sex hormones predict victimization frequency or risk.

“Obesity in men lowers testosterone levels and thereby reduces criminal perpetration rates.”

The proposed reduction in criminal perpetration is unsupported. Obesity can lower testosterone in men, but no evidence demonstrates that this hormonal effect causes less offending. The only cited longitudinal study examining obesity and later criminal outcomes instead reported higher adult felony-conviction prevalence among people with pediatric obesity, although it did not isolate men or test testosterone as a mediator.

“If a person appears in another person's dream, that person was thinking about the dreamer before falling asleep.”

Dreaming about someone does not establish that they were thinking about the dreamer before sleep. Research links dream content primarily to the dreamer’s own memories, relationships, experiences, and emotions, while no cited study demonstrates the claimed connection to another person’s mental state. Occasional coincidences do not support a universal rule.

“Low muscle mass does not impair estrogen production.”

Available evidence supports the practical conclusion that low muscle mass is not known to meaningfully reduce systemic estrogen production. Ovaries and adipose tissue are much more important estrogen sources, and research chiefly shows low estrogen contributing to muscle loss. Direct studies have not established that muscle loss has absolutely no effect, so the categorical wording is stronger than the evidence.

“Low muscle mass causes excessive aromatase activity.”

The cited evidence does not establish low muscle mass as a cause of excessive aromatase activity. Higher aromatase activity and reduced lean mass can occur together, but the available research primarily identifies adiposity and expanded adipose tissue as the relevant drivers. Evidence that muscle expresses aromatase—or that aromatase can affect muscle—does not support the claimed causal direction.

“Obesity makes men less violent because it lowers testosterone levels.”

The proposed causal explanation is unsupported. Obesity is associated with lower testosterone in men, but research does not show that this makes men less violent; testosterone’s relationship with human aggression is weak and does not establish causation. Several behavioral studies instead associate higher body mass with greater aggression or externalizing behavior, while limited arrest data cannot prove the claimed mechanism.

“An Ofsted survey of approximately 150,000 children aged 10 to 15 found that 32% worried about their bodies.”

Available evidence supports the reported 32% finding and its association with an Ofsted survey of children aged 10–15. However, the exact sample size rests on a secondary citation, while a potentially related official survey recorded 111,325 participants rather than approximately 150,000. The survey’s precise identity and respondent count therefore remain uncertain.

“Generational curses are real spiritual forces that cause misfortune or harmful behavior across family generations.”

No credible evidence establishes generational curses as spiritual forces causing family misfortune or harmful behavior. Intergenerational trauma and recurring behavioral patterns are real, but research explains them through genetic, psychological, environmental, social, and possibly epigenetic pathways. Religious writings document or debate belief in curses rather than proving supernatural causation.

“A doctor pronounced Mr. Anderson dead after the resuscitation attempt.”

The reported sequence is supported for Brian Anderson: CPR was attempted, and an on-call doctor later pronounced him dead. Records involving other people named Anderson do not contradict that account. Confidence is limited because the claim omits identifying details and relies on a single regional news report.

“Tim Andrews lived with a genetically modified pig kidney for nine months before receiving a deceased-donor human kidney, constituting the first known transition from a pig-kidney xenotransplant to a human kidney transplant.”

The evidence supports both the timeline and the historic characterization. Andrews lived with a genetically modified pig kidney for 271 days—about nine months—and subsequently received a deceased-donor human kidney, the first documented transition of this kind. He underwent roughly three months of dialysis between the two organs, so the transition was not immediate.

“Every person should drink 2 liters of water per day.”

A fixed two-liter drinking target does not apply to everyone. Authoritative recommendations vary by sex, age, activity, climate, health, and other circumstances, and many intake figures include water obtained from food and all beverages. Two liters may be suitable for some adults, but the evidence does not support it as a universal daily requirement.

“Magnetic resonance imaging (MRI) scans cause cancer.”

Available evidence does not support MRI scans as a cause of cancer. Unlike X-rays and CT scans, MRI uses non-ionizing magnetic and radiofrequency fields rather than DNA-damaging ionizing radiation, and no cancer increase from ordinary clinical MRI has been established. MRI has other recognized safety considerations, but they do not substantiate this cancer claim.

“Intermittent fasting is harmful to human health.”

Current evidence does not support characterizing intermittent fasting as generally harmful. Clinical reviews and trial meta-analyses find no overall increase in adverse events and report some weight and cardiometabolic benefits. Risks remain for people who are pregnant, have eating disorders, take certain diabetes medications, or follow fasting regimens without appropriate supervision; long-term evidence is also less certain.

“Coffee consumption causes miscarriage.”

Coffee has not been established as a cause of miscarriage. Moderate caffeine intake—generally under 200 mg per day—has not been shown to raise miscarriage risk, while some observational studies associate higher intake with greater pregnancy-loss risk. Those studies cannot reliably separate caffeine’s effect from other factors and therefore do not prove causation.

“Eating banana peels prevents H1N1 influenza infection.”

Eating banana peels has not been shown to prevent H1N1 influenza infection. The relevant research concerns a molecularly engineered banana-derived lectin tested in laboratory and animal models, not ordinary banana peels consumed by humans. Expert commentary explicitly states that eating bananas has no demonstrated antiviral benefit.

“GLP-1 receptor agonist treatment has numerous side effects, including adverse effects on eyesight.”

GLP-1 treatment can have many side effects, and official safety information documents potential eye complications. The clearest evidence concerns semaglutide, including diabetic-retinopathy complications and very rare NAION, which can cause vision loss. Evidence does not establish the same ocular risk for every GLP-1 drug, and several broad analyses have found no significant overall increase in eye disorders.

“Investigational glucagon-like peptide-1 (GLP-1)/glucose-dependent insulinotropic polypeptide (GIP)/glucagon triple-receptor agonists have a lower rate of serious adverse events than GLP-1 receptor agonist medications.”

Available evidence does not establish that triple-receptor agonists cause fewer serious adverse events than GLP-1 receptor agonists. Reported estimates are generally similar, statistically inconclusive, or based on placebo comparisons rather than direct comparisons with GLP-1 medications. Evidence also comes predominantly from retatrutide studies, so it cannot support a class-wide safety advantage.

“Compounded or unapproved peptide injections pose greater safety risks than approved prescription peptide medications.”

The evidence supports a higher overall safety risk for compounded or unapproved peptide injections than for approved prescription peptide medicines. These products may lack FDA premarket review, standardized manufacturing controls, and verified purity or potency, increasing risks such as contamination and immune reactions. Proper pharmacy compounding is generally safer than gray-market use, but it still does not provide the same assurances as an approved product.
