It's long been exasperating to the organic food industry -- the oft-stated belief that organic food is most notable for what it doesn't give you – all those yummy pesticides and chemicals. Nutritionally, common wisdom goes, organic food is no better for you than the conventional stuff.

Maybe not.

A study by researchers at Newcastle University,in England, published in the Journal of Dairy Science, has poked a hole in that thinking, showing that organic milk does have some nutritional advantages over conventional -- less saturated fat and more "good" fatty acids -- specifically omega-3s.
