of the questions from 30 to 34.
The popularity of organic foods can be traced to many people’s nostalgia for a simpler, more
pioneer-like life style. And many people believe that organic foods are safer than foods produced on a
large scale by traditional methods. Many people also believe that these organic foods contain more and
better nutrients than conventional food.
In fact, plants absorb all their food directly from the soil in inorganic form, no matter where the
nutrients may originally have come from. Experiments in Michigan and in England that went on for
twenty-five years were unable to find any difference in plants raised organically and plants raised with
chemical fertilizers. Things that do affect nutrient content are climate, time of harvest, and genetics -
but no difference results when plants are grown organically.
Neither are organically grown plants free from chemicals such as pesticides. Some pesticides leave
traces in the soil for years; these traces may be absorbed by the plant that is “organically” grown.
Rainfall may wash pesticides from neighboring farms onto “organic” fields, and sprays or other
applications of chemicals may drift and cause the same problem.
Furthermore, all foods - whether grown
conventionally
or organically - may contain toxic
substances to some degree; the Food and Drug Administration (FDA) maintains constant checks to
ensure that these substances are kept at a harmless level. But aflatoxin, a mold that causes cancer, may
grow on crops such as peanuts, or be present in milk. Lead and arsenic are sometimes present in bone
meal or seafood. And many vegetables contain poisonous compounds such as oxalic acid and nitrite
compounds. The point is, all these toxins may be present in a given food, no matter how the food was
grown and cultivated. Toxic substances in food do not necessarily have to come from fertilizers or
chemical sprays.
