Nutrition & DietBanned Pesticide DDT Linked to Quadrupled Alzheimer's Risk Still Lurks in Food Supply
DDT was banned in the US in the 1970s, but its breakdown product DDE still contaminates over 90% of Americans' bloodstreams. Research from Rutgers found Alzheimer's patients had significantly higher DDE blood levels, with the highest-exposed individuals facing roughly four times the odds of developing the disease. Lab studies show DDE raises amyloid precursor protein in human brain cells, suggesting a biological mechanism. Because these toxins accumulate up the food chain, meat, fish, dairy, and eggs contain 5–10 times higher levels than plant foods. Shifting toward a plant-based diet appears to significantly reduce DDE body burden and may lower long-term Alzheimer's risk.
