Lifestyle diseases

Lifestyle diseases (also called diseases of longevity or diseases of civilization) arediseases that appear to increase in frequency as countries become more industrialized and people live longer. They include:

• Alzheimer's disease
• Atherosclerosis
• Cancer
• Chronic Liver Disease or Cirrhosis
• Chronic ObstructivePulmonary Disease or COPD
• Diabetes mellitus
• Heart disease
• Nephritis or CRF
• Osteoporosis
• Stroke

Lifestyle diseases and alternative medicine

Changes in diet, lifestyle, and environment are thought to be factors which influence susceptibility to such diseases by biologically based branches of alternative medicine .

In some alternative health interpretations, such diseases are a result of an inappropriate relationship between people andtheir environment . The onset of degenerative diseases is insidious, they takeyears to develop, and once encountered are not readily cured.

The basic evidence that supports the existence of lifestyle diseases is the different incidences of diseases and causes ofdeath in various nations and cultures, as evidenced in compiled statistics.

International variation in cancer rates

A recent research paper published in the Lancet discussed the variation incancer rates that evidences the existence of lifestyle diseases.

"In many [Western] countries, peoples' diet changed substantially in the second half of the twentieth century, generallywith increases in consumption of meat, dairy products, vegetable oils, fruit juice, and alcoholic beverages, and decreases inconsumption of starchy staple foods such as bread, potatoes, rice, and maize flour. Other aspects of lifestyle also changed,notably, large reductions in physical activity and large increases in the prevalence of obesity."

"It was noted in the 1970s that people in many Western countries had diets high in animal products, fat, and sugar, andhigh rates of cancers of the colorectum, breast, prostate, endometrium, and lung; by contrast, individuals in developing countries usually had diets that were based on one ortwo starchy staple foods, with low intakes of animal products, fat, and sugar, and low rates of these cancers."

"These observations suggest that the diets [or lifestyle] of different populations might partly determine their rates ofcancer, and the basis for this hypothesis was strengthened by results of studies showing that people who migrate from one countryto another generally acquire the cancer rates of the new host country, suggesting that environmental [or lifestyle factors]rather than genetic factors are the key determinants of the international variation in cancer rates."[1]

Death statistics in the United States

An analysis of the death statistics of the United States reveals someinteresting facts that support the existence of the lifestyle diseases.

In 1900, the top three causes of death in the United States were pneumonia / influenza , tuberculosis , and diarrhea /enteritis. Communicable diseasesaccounted for about 60 percent of all deaths. In 1900, heart disease and cancer were ranked number four and eight respectively. Since the 1940s, most deaths inthe United States have resulted from heart disease, cancer, and other degenerative diseases . And, by the late 1990s, degenerative diseases accounted for more than 60percent of all deaths.

In 1900, these top three causes of death were from communicable diseases. Since the 1940s, most deaths have come from acompletely different category of disease called lifestyle diseases, or diseases of longevity, which have been unmasked by theamelioration of diseases that previously caused death at younger ages.[2] Until the present era, death was largely due toinfections, malignancies, injuries, poisonings, and war.
