Esoteric voodoo health crap, Gwyneth ain't the worst, anti-vaccinators are, but she's bad enough. I always marvel at how much resonance these people have, especially with women. If you've lived like me for a couple of years in the tropics and seen how the absence or dearth of conventional medicine availability negatively affects the health situation of a population, you're literally cured from this cloud-cuckoo-medicine stuff.
In Germany, whole parts of the population have fallen for this homeopathy/alternative medicine bullshit. Finish doesn't affect sound - as this most scientific of fora has often determined and re-established - and homeopathic medicine doesn't affect health (except for making it worse for lack of effective counter-measures).
