Exploding Field of Dreams

When you think of American agriculture do you think of vast fields of corn or acts of terrorism? Ammonia, the source of nitrogen that stimulates crops to grow large is also what was used to blow up the Oklahoma courthouse as well as other acts of terrorism.

Nitrogen, while necessary in the right balance, is also responsible for terrorism to our soil, water and air. The Green Revolution which started after World War II, heralded an expansion of agriculture with the use of ammonia nitrogen. It was a great triumph of quantity over quality. Only about 30 % of fertilizer reaches the intended plant. The rest stays in the soil where it destroys the natural organisms which plants need. Nitrogen also evaporates into the air, and it runs off into lakes and rivers causing algae blooms and increasing water acidity. The manufacturing of ammonia also contributes to global carbon dioxide emissions.

The story of agriculture is similar to that of medicine. Chemical farming led us away from caring for our earth, air and water. Chemical medicine upsets the ecology of our bodies and ignores the underlying healthy processes.

Drugs: No Comparison

Researchers from Harvard, writing for the Journal of the American Medical Association, have concluded that, “Many of our nation’s research priorities are driven by the pharmaceutical industry. These companies, not surprisingly, focus most of their attention on new therapies.”

This is what I’ve been writing about for years. How can we improve our health when the powerful pharmaceutical industry controls research? Their goal is to make money. New drugs make more money, whether they’re any better than the old or not.

Among this study’s conclusions was that few drugs are ever compared with other drugs for safety or efficacy. Instead they’re usually compared to placebos. When drugs are compared one on one, the report states, they usually don’t compare safety. Doctors and patients can be lured into thinking that the new drug on the block is better than an older, less expensive, drug, when in reality the question was never asked. This is one of the reasons why drug companies make more profits than any other industry.

It goes without saying that drugs are rarely compared to lifestyle changes such as diet and exercise. Drug studies also tend to be relatively short in duration, months rather than years, and limit their scope to very narrow parameters (ie, does it lower cholesterol, not whether it prolongs life).

There is one area where I have seen comparative studies. Cancer research usually involves comparing two chemotherapy programs or chemotherapy to radiation. You’ll never see a cancer therapy compared to life style changes or even doing nothing. Cancer researchers would argue that it would be unethical to use humans with cancer in a study and give them nothing, but the fact is they usually have no idea whether patients undergoing chemotherapy or radiation are in fact helped at all. They may be able to tell you therapy X prolonged survival over therapy Y, but not if either prolonged life over no therapy.

The American public has been dazzled by the advances in medicine over the past few decades. And there have been remarkable achievements. As more reports like this one emerge, the public will undergo a slow awakening to the dangers of allowing a largely unregulated industry to dictate how medical research is conducted.

Drug Side Effects in the Elderly

The elderly aren’t the only ones being prescribed pharmaceuticals, but they’re more likely to be taking several. Along with children, the elderly are most likely to have adverse reactions to medicines. This is mostly due to their lessened ability to detoxify and remove chemicals from the body.

From: (Public Citizen)

Each year, more than 9.6 million adverse drug reactions occur in older Americans. The referenced study found that 37% of these adverse reactions were not reported to the doctor, presumably because patients did not realize the reactions were due to the drug. This is not too surprising considering that most doctors admitted they did not explain possible adverse effects to their patients.

The following national estimates are based on well-conducted studies, mainly in the United States:

  • Each year, in hospitals alone, there are 28,000 cases of life-threatening heart toxicity from adverse reactions to digoxin, the most commonly used form of digitalis in older adults. It is estimated that as many as 40% or more of these people are using this drug unnecessarily, even by pro-pharmaceutical researchers. Therefore, many of these injuries are preventable.
  • Each year 41,000 older adults are hospitalized—and 3,300 of these die from ulcers caused by NSAIDs (nonsteroidal anti-inflammatory drugs, usually for treatment of arthritis). Thousands of younger adults are hospitalized due to these drugs.
  • At least 16,000 injuries from auto crashes each year involving older drivers are attributable to the use of psychoactive drugs, specifically benzodiazepines and tricyclic antidepressants. Psychoactive drugs are those that affect the mind or behavior.
  • Each year 32,000 older adults suffer from hip fractures—contributing to more than 1,500 deaths—attributable to drug-induced falls. In one study, the main categories of drugs responsible for the falls leading to hip fractures were sleeping pills and minor tranquilizers (30%), antipsychotic drugs (52%), and antidepressants (17%). All of these categories of drugs are often prescribed unnecessarily, especially in older adults, according to medical experts that are not anti-drugs. The in-hospital death rate for hip fractures in older adults is 4.9%. Multiplying this times the 32,000 hip fractures a year in older adults attributable to drug-induced falls, 1,568 older adults die each year from adverse drug reactions that cause hip fractures.
