Health Topics
Evidence-based coverage of the chemicals, lifestyle factors, and biological systems that shape long-term health. Each topic covers what the research shows.
Chemicals and contaminants encountered through air, water, food, and everyday materials. What the evidence says about their effects on the body.
The chemicals present in homes, food, air, and consumer products. How they enter the body and what the research shows about long-term exposure.
Plastic particles now found in blood, lungs, and organs. What they are, where they come from, and what current research says about biological effects.
Lead, mercury, cadmium, and arsenic in food, water, and soil. Exposure pathways, accumulation in tissue, and the health outcomes associated with chronic low-level exposure.
What’s in tap water, filtered water, and bottled water. PFAS, chlorine byproducts, nitrates, and what filtration removes.
Mold in buildings and food produces mycotoxins that affect immune and neurological function. What the research shows about exposure, testing, and remediation.
Chemical residues from agricultural and household pesticide use found in food, water, and soil. Exposure pathways, what washing does and does not remove, and what the research shows about long-term effects.
The daily factors that influence how the body functions. What you eat, how you move, how you sleep, and how technology use affects biological health.
Food quality, chemical residues in the food supply, and the nutritional research that separates signal from noise in one of the most contested areas of health science.
How physical activity affects inflammation, hormonal regulation, and long-term disease risk. What the evidence shows about type, frequency, and intensity.
Sleep drives cellular repair, immune function, and cognitive health. What the research shows about duration, quality, and the environmental factors that disrupt both.
EMF exposure, screen time, blue light, and the biological effects of living in close contact with wireless technology. What the current research supports.
The internal systems that determine how the body responds to chemical and lifestyle factors. Understanding them changes what clean living means.
How genetic variation affects individual responses to toxins, nutrients, and environmental stress. What this means for personalized approaches to health.
How environmental exposures and lifestyle factors change gene expression without altering DNA sequence. Why early and sustained exposure reduction matters.
The biological mechanisms of aging: cellular senescence, mitochondrial function, inflammation. What the evidence shows about what slows or accelerates them.
How cumulative exposure, chronic inflammation, and oxidative stress develop before symptoms appear. The upstream factors that shape long-term health trajectories.
