As far as Organic food is concerned, I think that whilst there may not be anything proven about the difference (ignoring that stupid report this week about it not being any different), common sense tells me that to eat food that has not been sprayed from the minute it appears out of the ground or comes into bud with a constant drenching of fungicides, herbicides, pesticides, fertilizers and any other 'cides or 'izers you can think of, and that is grown in soil that has not had all the goodness drained out of it has to be ultimately more beneficial for the body.
Our poor beleaguered livers have enough to contend with from the chemical pollution in the water, the air, the creams, make-up, shampoo, cleaners, washing detergent, cream soaps, etc., etc., etc., that they really don't need to have any extra burden from our food.
Much of our meat (especially the cheaper supermarket stuff) comes from animals that are reared in vast enclosures without ever seeing a blade of grass, are injected with concoctions of drugs and chemicals, and fed goodness knows what for food.
Whilst an odd thing here and there may not be a problem, what cumulative damage are all these things doing to us? The damage they are doing to the environment is widely recognised - are we invincible??? Obviously not, otherwise we wouldn't get sick!
We rather naively think that because we can't see or taste the chemicals in our food it isn't there. Those who grow their own food would be happy to regale you about the difference in taste and flavour of unadulterated freshly grown fruit and vegetables.
There was a comparison done a while ago between vegetables from a large supermarket and those grown on an organic farm. Some of the organic vegetables had as much as 90% higher nutritive value! Of course, there is organic and there is organic, and nothing will beat pulling it fresh out of your own garden, but I would err on the side of common sense any day.
