  • The Hype of Healthier Organic Food Some people buy organic food because they believe organically grown crops are more nutritious and safer for consumption than the people who purchase their conventionally grown counter parts, which are usually produced with pesticide sand synthetic fertilizers. In the name of health, spending. $1.60 for every dollar they would have spent on food that is grown in a manner that is considered conventional. Scientific evidence, therefore, suggests that consumers do not reap significant benefits, in terms of either nutritional value or safety, from organic food. Although advocates of organic food preserve that organic produce is healthier than conventionally grown produce because it has more vitamins and minerals, this assertion is not supported by scientific research. For instance, one review published in The American Journal of Clinical Nutrition provided analysis of the results of comparative studies conducted over a span of 50years, researchers consistently found no evidence thatorganic crops are more nutritious than conventionally grown one sin terms of their vitamin and mineral content. Similarly, Stanford University researchers who examined almost 250 studies comparing the nutritional content of different kinds of organic foods with that of their non organic counter parts found very little difference between the two. Evidence also undermines the claim that organic foodis safer to eat. While researchers have foundlower levels of pesticide residue in organic produce than in non organic produce,the pesticide residue detected in conventional produce falls with in acceptable safety limits. According to such organizations as the US Environmental Protection Agency,the minute amounts of residue falling with in such limits have no negative impact on human health. Based on scientific evidence, organic food offers neither significant nutritional or safety benefits for consumers. Proponents of organic food, of course,are quick to add that their are numerous other reasons buy organic food, such as, a desire to protect the environment from potentially damaging pesticidesora preference for the taste of organically grown foods. Research regarding these issuesis less conclusivethan the findings regarding nutritional content and pesticide residue safety limits. What is clear, though, is this: if a consumers goal is to buy the health i.e stands a fest food to eat, the increased cost of organic food is a waste of money.
