The dietary effects on health are poorly understood. Nutrition studies are fraught with difficulties and have spawned a resurgence in methodology concerning "measurement error" in the field of statistics. You don't really know how much pizza you ate last year, but the survey will ask you to estimate it somehow... and this kind of measurement is 'noisy'.

Conventionally-grown food looks like organically grown food on steroids, to me. I suppose from the outside a human on steroid may look healthy -- Mr Universe, even -- but we know all is not well inside.

I'm not saying that's really related, but there is substantial evidence for real differences in the makeup of food grown conventionally vs organically.

Quantitative proteomics to study the response of wheat to contrasting fertilisation regimes - http://vwordpress.stmarys-ca.edu/bdf2/files/2013/05/wheat-an...

"... The abundance of 111 protein spots varied significantly between fertilisation regimes. Flag leaf N and P composition were significant drivers of differences in protein spot abundance, including major proteins involved in nitrogen remobilisation, photosynthesis, metabolism and stress response."
