Free Radicals May Not Be Cause of Aging
An anonymous reader writes "Researchers at McGill University in Montreal have uncovered strong new evidence that that wildly-accepted mitochondrial free radical theory of aging (MFRTA) is wrong. MFRTA suggests that free radicals cause oxidative damage, which in turn leads to the aging process. This new evidence shows that high levels of Reactive Oxidative species are rather a biological signal used to combat aging then the process itself. This goes against claims of major health benefits from consuming foods and particularly supplements that contain antioxidants."
Organic food is almost all grown the exact same was as regular food: on large, industrial farms, in large volumes, for a profit. The only difference is that the expense of Organic food comes from the limited supply (due to demand as well as a higher rate of spoilage), while the expense of normal food comes from making it better, cheaper, and safer.
Are you trolling, or just ignorant? Most people don't know what organic food is, but if you're going to make an argument about it, why not educate yourself on the subject first rather than just spout your own prejudices for everyone on the internet to read?
Food quality has been on a steady decline. Poisons and hormone-mimickers in food are steadily going up while nutrients like minerals and vitamins are going down. Read the studies about it and wonder why this is so, all while buying cheaper food in larger quantities. The long list doesn't end there however, the earth itself is being drained of nutrients due to unhealthy mono-culture and non-stop farming each and every year. For many farmers, this is more important, so there is a big shift today to organic farming, just because of the higher sustainable development factor. If we destroy the earth, famine is not too far away. If we destroy nature or cut outself out from it too much, we may have to turn to genetic engineering to be able to sustain healthy bodies, always fighting new unknown diseases, not a very pleasant prospect except for the medical industry.
Organic farming can be many different ways, with the more extreme end being biodynamic farming. It is true that you can have large farms producing roughly the same yield as "modern farms", at least if you compare nutrients. Many people have the opinion that you can eat less of organic foods, and still feel satiated. So less yield does not necessarily mean less food.
This clockwork-universe mentality that everything to food and life is about proteins, minerals, vitamins, and this obsession of getting rid of dirt and bugs, is well, an hypothesis without basis in nature. Many people believe that there is more to food than what we can measure in its quantities. Life is certainly about more than its parts. If you lack this understanding, you've been living in the city for too long. It's clouding your judgement, so time to take a break off media and city, find some new fresh perspectives in nature.

Btw, IANAF (I Am Not A Farmer), however, I know there is alot to organic farming and sustainable development, than our prejudices. Currently living outside major cities, and it does bring a different perspective to life than endless visits to cafes and caffe lattes.
Before you condemn something, at least give it a fair shot first, hmm?
