Are Organic Foods Really Better For You?
What Consumers really want is good, clean, safe foodIs that too much too ask?

“Our goal of no-GMO ingredients in our Whole Foods market brand and 365 products is focused on accessing ingredients derived from non-genetically modified seeds. Unfortunately, absolute “GMO-free” guarantees cannot be made on any manufacturer’s product. Not only is it impossible to test every container of product, but currently there is no system in the United States to guard against drift from farmers using GMO seed that could potentially contaminate non-GMO crops.”

Sixty-eight percent of the respondents in a recent US poll said a product labeled “USDA Certified Organic” would indicate the food was safer than non-organic foods
Sixty-seven percent believe the label would indicate food of higher quality than non-organic foods
Sixty-two percent believe the label would mean the food is more healthful for consumers than non-organic food
Is Organic more nutritious?

The head of the U.S. Organic Trade Association recently had to admit organic food was no more nutritious than any other food and that organic food standards had nothing to do with food safety

Organic Advocates Argue: Wiser Land Use. Less Pesticides. More Biodiversity.
Sustainable Agriculturists Argue….
Is the Organic solution viable for sustainable world agriculture?

Critics argue:
Feeding Humanity From Organic Fields Would Mean Cropping Twice As Much Land As We Currently Plant
Is the Organic solution viable for sustainable world agriculture?
Are There Unknown Risks to the Environment?
• Gene transfer to other crops or wild plants
• Change in herbicide use patterns
• Squandering of valuable pest resistance genes
• Poisoning of wildlife• Creation of new or worse viruses• Un-assessable long term risks

PesticidesKillInsectsIndiscriminately
“A butterfly beats it’s wingsin the Amazon…
and changes the weatherin Chicago.”
In 1962, Carson wrote: “A truly extraordinary variety of alternatives to the chemical control of insects is available. Some are already in use and have achieved brilliant success. Others are in the stage of laboratory testing. Still others are little more than ideas in the minds of imaginative scientists, waiting for the opportunity to put them to the test. All have this in common: they are biological solutions, based on understanding of the living organisms they seek to control, and of the whole fabric of life to which these organisms belong. Specialists representing various areas of the vast field of biology are contributing—entomologists, pathologists, geneticists, physiologists, biochemists and ecologists—all pouring their knowledge and their creative inspirations into the formation of a new science of biotic controls”

Wild-type corn variety with secondary fungal infection
Bt corn resistant to corn borer damage, resulting in less secondary fungal infections
Organic vs. Transgenic
© life_edu
So while the organic standards may attempt to ensure freedom from pesticide residues, the freedom of organic foods from vermin, mycotoxins and other contamination may be less certain
MycotoxinsOrganic farmers are more likely to let their crops suffer rodent and insect damage, which leads to more fungal infections and more natural toxins in the food
What the public wants is safe food that is good

Perhaps New Organic Food Standards Could Use Warning Labels
Organic Products Are Not Necessarily Tastier, Healthier Or Pesticide-Free
© life_edu
Organic agriculture is not a
food safety claim (FDA) Organic means only that the farmers use organic fertilizer instead
of chemical fertilizer and “natural” pesticides such as copper sulfate (broadly toxic) and sulfur (a soil contaminant)
