I am skeptical about many of the published studies on food and health. Red meat for example. A lot of those studies on red meat consumption were carried out in the States where cattle are given feeds that are banned in the EU. They are also given growth hormones and prophylactic antibiotics. I'd be surprised if red meat consumption didn't cause problems in humans in those conditions. Also, people who eat a lot of red meat are often the same who barbecue every weekend, eat saturated fats (especially trans fats etc) and drink too much alcohol. So how the hell can the researchers make sweeping conclusions that the red meat is to blame...?
Are health-endangering foods sold in the EU? Yes, I think they are. I gave up drinking homogenized milk a couple of years ago and annoying digestive problems I'd been having for years have disappeared. I believed I was lactose intolerant - but laktoositon "milk" made no difference. Now I am convinced that the homogenization process was the source of my misery! Luomu milk is sometimes homogenized (Lidl's luomu milk is homogenized) - so, in that case, buying organic would have little to do with avoiding the potential health issue. So I buy luomu milk that has not been homogenized. It is more expensive but no more expensive than the lactose-free drink that I had been buying. (And if it means the cows are happy cows then that's good too).
And of course, trans-fats are a legal substance in the EU but are almost certainly harmful (and as far as I know organic foods probably do not contain trans fats).
The Luomo/Organic/Bio thing is a can of worms. As a beekeeper I've studied the topic and concluded that there is no point in us spending money to get a LUOMU logo when we are happy that our honey is good quality (I have lab reports to prove it). But - the criteria for organic honey vary in every country in the EU (and beyond) as do the controls that are in place to oversee the labelling. So the skeptic in me would be reluctant to pay more for "organic" honey from any source. In some countries "organic" means having wooden bee hives. Yet most bee keepers would agree that wooden hives are a source of bacterial infections, moulds etc which necessitate chemical control. In some countries organic hives must be situated X km from the nearest road, yet research of urban hives has shown that "city honey" contains none of the polluants that might be associated with vehicle emissions.
... and so on and so on.
