Human diets have changed dramatically over the last few hundred years, and as a consequence so have our diseases. The most recent shift in diet over the last hundred years has resulted in a shift from infectious diseases to degenerative diseases. This trend is summarized in the following Wikipedia entry.
Lifestyle diseases, from Wikipedia:
"Lifestyle diseases (also called diseases of longevity or diseases of civilization) are diseases that appear to increase in frequency as countries become more industrialized and people live longer. They include Alzheimer's disease, atherosclerosis, asthma, cancer, chronic liver disease or cirrhosis, Chronic Obstructive Pulmonary Disease, Type 2 diabetes, heart disease, nephritis or chronic renal failure, osteoporosis, acne, stroke, depression and obesity.
Death statistics in the United States
In 1900, the top three causes of death in the United States were pneumonia/influenza, tuberculosis, and diarrhea/enteritis. Communicable diseases accounted for about 60 percent of all deaths. In 1900, heart disease and cancer were ranked number four and eight respectively. Since the 1940s, the majority of deaths in the United States have resulted from heart disease, cancer, and other degenerative diseases. And, by the late 1990s, degenerative diseases accounted for more than 60 percent of all deaths.

My point here is that all of the so-called lifestyle diseases are also based on inflammation. I checked the research literature for studies of the response of each of these diseases to diets supplemented with omega-3 fish oils. Studies had been performed in each case. Reduction of inflammation by fish oil treatment was uniformly effective in reducing symptoms of all of the degenerative diseases. Other diseases that can be added to the inflammatory list are spinal disc problems and hypertension. It is interesting that disc dislocations are associated with coeliac, an inflammatory/autoimmune disease. It is also interesting that acne and depression are listed. Acne is indirectly associated with diet, but if sufferers shift to an anti-inflammatory diet, acne symptoms disappear. Depression associated with childbirth is particularly responsive to anti-inflammatory drugs, diet and exercise. Most of the symptoms associated with aging are just due to inflammation and are similarly responsive to anti-inflammatory lifestyle changes
To summarize:
- Modern degenerative diseases are caused by modern inflammatory diets (and insufficient exercise.)
- Anti-inflammatory diet and lifestyle reduce degenerative diseases.
- Aging is predominantly mismanaged inflammation.
