Topic
Claims about minerals, additives, pH, detox, natural products and chemistry where concentration and dose often matter more than labels.
Chemical names and long ingredient lists can sound alarming or impressive while saying little about biological importance. This topic focuses on composition, concentration, exposure and the difference between detecting a substance and receiving a meaningful dose.
Investigations
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.
Microwave ovens use radiofrequency electromagnetic radiation to heat food, but microwaves are non-ionizing: their photons do not carry enough energy to ionize atoms in the way X-rays or gamma rays can. Absorbed microwave energy becomes heat and does not make food radioactive. High microwave exposure can injure tissue through heating, which is why ovens are shielded, interlocked and subject to leakage limits; a damaged oven should not be treated as equivalent to normal operation.
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.
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.
