Medical, wellness and disease claims tested against clinical evidence, biological mechanism, dose, risk and study quality.
Health claims can cause direct harm when plausible stories substitute for evidence. We separate biological possibility from demonstrated clinical benefit, track absolute as well as relative risk, and distinguish laboratory findings from outcomes that matter to people.
Investigations
5G uses non-ionizing radiofrequency fields, but that does not by itself settle long-term cancer risk. Direct 5G-specific cancer epidemiology is still immature, broader human RF evidence has not shown increased risk for the best-studied tumours, and positive animal findings remain important but methodologically disputed. Ordinary 5G exposure has not been shown to cause cancer.
Diet changes renal acid load and can substantially change urine pH, but blood pH in healthy people is tightly regulated by respiratory and renal physiology. Human evidence does not support using alkaline diets or alkaline water to prevent or treat cancer by alkalizing the blood.
The vaccine-autism claim has been tested in large cohort studies, case-control studies, meta-analyses and evidence reviews. A 2019 Danish cohort of 657,461 children found no increased autism risk after MMR vaccination, including among children with elevated baseline risk, and a 2014 meta-analysis covering more than 1.2 million children found no association with vaccination, MMR, thimerosal or mercury exposure from vaccines. The 1998 paper that catalyzed the MMR claim was a 12-child case series, did not establish causation and was later retracted.
Some homeopathic preparations are diluted beyond the point where molecules of the starting substance are expected to remain. Proposed water-memory mechanisms and some laboratory studies claim persistent differences, and a 2023 review of homeopathy meta-analyses reported effects beyond placebo. But a reproducible molecular memory mechanism linking an absent solute to specific clinical effects has not been established, and condition-specific evidence remains inconsistent and often limited.
Vaccines can cause adverse events, including some rare serious events, and vaccine safety evidence has real limitations that require continued surveillance. Those facts do not establish an intentional program to create chronic disease. A 2013 National Academies review found no evidence that the then-current U.S. childhood schedule was unsafe while also identifying research gaps; post-licensure systems such as VAERS and VSD are designed to detect and investigate safety signals. Neither that historical schedule review nor the surveillance systems prove every vaccine policy optimal, but no verified documentary, epidemiological or mechanistic evidence establishes the claimed design-for-chronic-illness scheme.
Some deliberately engineered shielding structures can change RF absorption, but that does not validate generic anti-radiation stickers or 'harmonizing' discs. Direct tests of small commercial phone shields have often found no meaningful SAR reduction, and partial shielding can alter antenna performance or transmission power. Product-specific claims require product-specific independent measurements.
Detoxification is a real biological and medical concept: the body chemically transforms and excretes many substances, and specific poisonings can require targeted treatments such as chelation or antidotes. Commercial 'detox' claims usually fail to identify the toxin, dose, biomarker and elimination pathway needed to test the claim. A critical review found very little clinical evidence for detox diets, and current NIH guidance says there is no compelling evidence that commercial detox programs eliminate toxins. Short-term weight changes or altered bowel output do not demonstrate toxin removal.
A small 2001 study of 11 aged cadavers found substantial fluoride in pineal tissue and a positive correlation between pineal fluoride and calcium, so claims that fluoride can occur in calcified pineal tissue have a real empirical basis. The study did not show that fluoride caused pineal calcification, impaired pineal function or reduced cognition. Separately, current systematic reviews report an association between higher fluoride exposure and lower childhood IQ, while evidence at drinking-water concentrations relevant to 0.7 mg/L community fluoridation remains limited and disputed. Neither line of evidence establishes a pineal-mediated cognitive effect or an intentional population-control program.
Grounding changes the body's electrical potential relative to Earth, so the intervention has a real physical effect. Small studies have reported changes in sleep, pain, blood measures and recovery, including sham-controlled experiments. But the clinical literature is small and pilot-scale, several influential papers have commercial or advocacy ties to grounding companies, and independent replication is limited. The proposed free-electron mechanism has not been established as a general therapeutic pathway.
Pink salt can contain more trace elements than refined table salt, but the amounts are generally too small to provide meaningful nutrition at sensible salt intakes. Its dominant dietary effect is still sodium chloride, and non-iodized pink salt may provide less iodine than iodized table salt.
Liquid water does have microscopic structure, but its hydrogen-bond network rearranges on ultrafast timescales. A 2025 cell study reported effects from a product described as energized structured water, but it did not establish persistent freeze-thaw structure or human health benefit. The broader claim remains unsupported.
Typical household Wi-Fi exposure is low, and human RF studies have not shown increased risk for the best-studied cancers. Experimental-animal evidence includes tumour findings, but the strength of that evidence and its translation to human household Wi-Fi are disputed. Cancer from normal household Wi-Fi exposure has not been demonstrated.
The Wim Hof Method has produced measurable physiological effects in small controlled studies. A 2014 randomized endotoxemia experiment showed that trained healthy volunteers could increase epinephrine and alter inflammatory cytokine responses. A 2024 systematic review found promising inflammatory signals, but also judged the underlying studies very low quality, small, heterogeneous and at very high risk of bias. That is not equivalent to proving treatment efficacy across diseases, and cold-water exposure has real safety risks.
