In a Congressional hearing on health, Senator Bernie Sanders (I-Vt.) confronted Robert F. Kennedy Jr., the anti-vaccine Health Secretary, regarding his rejection of germ theory, which posits that specific pathogens cause diseases. Senator Bill Cassidy fact-checked Kennedy's claims, emphasizing the scientific consensus on germ theory. Kennedy, known for promoting conspiracy theories and lacking a scientific background, advocates for terrain theory, suggesting that diseases arise from imbalances in the body rather than germs. This belief aligns with his Make America Healthy Again (MAHA) movement, which emphasizes healthy living and diet. Kennedy's controversial views on health have been mostly underreported, despite their potential implications for public health policy. His recent shift in stance on certain environmental issues, particularly his support for increased glyphosate production, further complicates his position as a health advocate.
