“Believing, incorrectly, that you’ve done something healthy by taking a vitamin pill makes you more likely to take genuine, concrete, real-world risks with your health. It’s a chilling thought, but ideas aren’t without impact, and every time we humour a harmless myth – that vitamin pills are healthy, that some fashionable berry prevents cancer – we might be doing more harm than we think.”—Ben Goldacre
