Alkaline water (pH 8-10) does not meaningfully change blood or tissue pH due to the body's robust buffering systems, and there is no clinical evidence that it cures, prevents, or treats diseases including cancer. Minor potential benefits for acid reflux or post-exercise rehydration have been noted but remain unconfirmed in larger trials.

Oral or intravenous sodium bicarbonate (baking soda) as a standalone cancer cure has no clinical evidence supporting it. While early-phase research explores sodium bicarbonate as an adjunct to conventional therapies, based on the observation that tumors create an acidic microenvironment, there is no evidence that consuming baking soda prevents or cures cancer in humans.

Bluetooth devices emit very low-power radiofrequency radiation, typically 10 to 400 times less than a mobile phone, that is non-ionizing in nature and well within safety limits set by international regulatory bodies. No scientific evidence establishes a health risk from Bluetooth at consumer exposure levels.

The human body continuously removes waste and metabolic byproducts through the liver, kidneys, lungs, and digestive system. 'Detox diets' and commercial cleansing products have no randomized controlled trial evidence demonstrating that they enhance this process or remove specific toxins, and some pose risks of harm.

Homeopathy, a practice based on extreme dilution of substances to the point where no molecules of the original substance remain, has no plausible mechanism and no high-quality clinical trial evidence demonstrating efficacy against cancer. Regulatory and scientific bodies worldwide classify it as ineffective for treating serious diseases, and relying on it in place of evidence-based cancer treatment is potentially fatal.

COVID-19 vaccines do not contain microchips, RFID trackers, or any tracking technology. Vaccine ingredients have been independently analyzed and contain no such components. The claim originated from a misinterpretation of Bill Gates' remarks about digital health records.

Miracle Mineral Solution (MMS) is a mixture of sodium chlorite and acid that produces chlorine dioxide, an industrial bleaching agent, when prepared as directed. The FDA, Health Canada, the European Commission, Medsafe New Zealand, and other regulatory bodies warn that ingesting MMS is equivalent to drinking bleach, has caused hospitalizations and deaths, and has no scientific evidence of efficacy for any medical condition.

Decades 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.

Vitamin C is an essential nutrient with well-established roles in immune function and tissue repair. However, evidence does not support claims that megadose supplementation prevents or cures most diseases. A Cochrane review of 29 trials found no reduction in common cold incidence from vitamin C supplementation in the general population, though it modestly reduces cold duration.

Wi-Fi operates using radiofrequency electromagnetic fields (RF-EMF) classified as non-ionizing radiation. Major health and regulatory bodies including the WHO and ICNIRP have concluded that exposure from Wi-Fi at levels encountered in everyday life is below thresholds associated with established health effects. Some researchers argue that non-thermal effects warrant further study, keeping the topic contested at the margins.
