Is Organic Food Really Healthier




Is Organic Food Really Healthier

Don't ask the US federal government whether there are any health benefits to eating organic food. It won't tell. No mere coincidence, then, that no pictures of farmers or farms (or fertilizers or pesticides) appear in the USDA food pyramid logo. The federal government encourages the consumption of more fruits, vegetables, and grains, but stops short of evaluating the farming systems that produce these same foods. An apple is an apple regardless of how it has been grown, the USDA food pyramid suggests, and the only take-home message is that we should all be eating more apples and less added sugars and fats.

But this message may be too simplistic. Over the past decade, scientists have begun conducting sophisticated comparisons of foods grown in organic and conventional farming systems. They're finding that not all apples (or tomatoes, kiwis, or milk) are equal, especially when in comes to nutrient and pesticide levels. How farmers grow their crops affects, sometimes dramatically, not only how nutritious food is but also how safe it is to eat. It may well be that a federal food policy that fails to acknowledge the connection between what happens on the farm and the healthfulness of foods is enough to make a nation sick.

The Results Are In

In the late 1990s, researcher Anne-Marie Mayer looked at data gathered by the British government from the 1930s to the 1980s on the mineral contents of 20 raw fruits and vegetables. She found that levels of calcium, magnesium, copper, and sodium in vegetables, and of magnesium, iron, copper, and potassium in fruit had dropped significantly.

The 50-year period of Mayer's study coincides with the post World War II escalation of synthetic nitrogen and pesticide use on the farm. These powerful agri-chemicals allowed farmers to bypass the management-intensive methods of maintaining soil fertility by replenishing soil organic matter with cover crops, manure, and compost, and of controlling pests with crop rotation and inter-cropping. Reliance on chemical fertilizers and pesticides became a defining characteristic of conventional farming, while farmers who eschewed the use of agri-chemicals came to be considered organic.


of course it is, I have known this since early 70's when we did community gardens in Raleigh, NC with NOAH'S Food Co-op.
